Impact of Agroecological Practices on Crop Yield and Food Security in Southwestern Nigeria

This study examines the impact of agroecological practices on crop yield and food security in Southwestern Nigeria. Using data collected from a sample of smallholder farmers, descriptive statistics and regression analysis were employed to assess the relationship between agroecological techniques—such as organic farming, crop rotation, and integrated pest management (IPM)—and agricultural outcomes. The findings reveal that agroecological practices significantly improve crop yield, with organic farming having the strongest positive effect, followed by crop rotation and IPM. Additionally, these practices were associated with higher food security index (FSI) scores, indicating enhanced household food security compared to non-agroecological methods. While soil fertility management showed a positive relationship with yield, it was not statistically significant. The results underscore the potential of agroecological approaches to foster sustainable agricultural development, addressing the dual challenges of productivity and food insecurity in the region. The study recommends promoting these practices through policies and programs that support smallholder farmers, thereby enhancing agricultural resilience and economic well-being.

Effects of Species-Rich Perennial Inter-Row Cover on Weed Flora and Soil Coverage in an Apple Orchard: A Case Study of Opportunities and Limitations in a Dry Continental Climate

The planting of inter-row cover vegetation has long been practised in Western European fruit-growing regions, yet research in this area remains limited in many countries. With the rise of organic farming, the role and selection of inter-row cover species are becoming increasingly important. Proper species selection enhances weed control and promotes biodiversity, supporting flowering plants and beneficial insects in orchards. The six-year research aimed to develop a multi-species, perennial, multifunctional inter-row cover species mixture for a dry continental climate, which is suitable for soil protection and the displacement of heat-loving, drought-tolerant, invasive weed species. There was another expectation for this native seed mixture to be able to regenerate spontaneously and to be sustainable in the orchard for a long time with minimal maintenance. Based on our results, the two multi-species mixtures (15 and 18 species) successfully reduced the cover of weed species, and their composition changed in the direction of the natural flora characteristic of the area. According to general management practices, native species could not widely appear in the control rows created by mowing the local weed flora.

Organic Farming in India: A Dual Strategy for Climate Change Adaptation and Mitigation

Recent decades have transformed Indian agriculture from traditional methods to a mechanized system reliant on fossil fuels, chemical fertilizers, and pesticides, increasing greenhouse gas emissions and impacting global climate. Higher greenhouse gas levels, including carbon dioxide, methane, and ozone are likely, causing the observed rise in air temperatures and leading to significant climate shifts. In most subtropical regions, a 4°C rise in global temperatures is anticipated to reduce groundwater and surface water, heightening food demand and threatening global food security. Climate change denotes long-term, significant alterations in climate measurements. A production system that maintains the health of ecosystems, soils, and human populations is known as organic farming (IFOAM 2006). Organic farming is energy-efficient and reduces greenhouse gas emissions by minimizing chemical and fossil fuel use, while enhancing soil carbon, biodiversity and fertility. It reuses plant and animal waste to restore soil nutrients, relies on renewable resources and supports sustainable, low-pollution management. Organic farming not only helps to mitigate climate change but also provides lasting benefits as an adaptation strategy. Effective nutrient management and carbon sequestration in soils are crucial for adapting and mitigating climate change across diverse temperature zones and local conditions.

Assessment of Different Organic Manures on Yield of Broccoli (Brassica oleracea var. Italica Plenck.) cv. KTS-1 under Bundelkhand Climatic Condition

Aims: The organic content in manure helps soil retain moisture, increases gas exchange, and introduces beneficial bacteria, loosens clayey soil, promoting root growth. Soil with a higher organic content is more resistant to erosion and produces superior crops. Using organic manure decreases farming's environmental impact. Unlike synthetic fertilizers, it recycles waste materials, nourishes the soil, and nurtures crops. Methods: This experiment was carried out during Rabi 2023-24 at the Organic Research farm Kargunwan ji, Department of Horticulture, Institute of Agricultural Sciences, Bundelkhand University Jhansi (Uttar Pradesh). Broccoli (Brassica oleracea var. italicaPlenck.) cv. KTS-1 was sown under randomized block design (RBD) with 11 treatment viz., Control, Vermicompost 100%, Cow litter 100%, Pressmud 100%, Vermicompost 75%, Cow litter 75%, Pressmud 75%, Vermicompost 50%+Cow litter 50%, Cow litter 50%+Press mud 50%, Pressmud 50%+Vermi 50%, Pressmud 33%+Cow litter 33%+Vermi 33% with 3 replication accommodating spacing (60 × 45) cm2,plot size (2.4 × 1.8) m = 4.32 m2 with total gross experimental area of (23.5 x 9.6) m = 225.06 m2. Results: Results shows thatat harvest, treatment T10 took to the minimum curd initiation at 53.10 days, compared to the control plot at 68.07 days. Similarly, days to 50% curd initiation and maturity were also shorter in T10, at 67.03 days and 80.13 days, respectively, while the control plot took (78.03 and 96.13) days. Ttreatment T10 produced the largest curd diameter (14.78 cm) and weight (321.03 g), significantly surpassing the control plot (6.37) cm diameter and (138.43) g weight. Overall, T10 yielded (321.03) q/ha, markedly higher than the control plot (138.43) q/ha, demonstrating significant improvements in broccoli yield and quality. Conclusion: The results clearly revealed that the application of organic treatments, particularly T10 (Pressmud 33% + Cow litter 3% + Vermi 33%), significantly enhanced the yield and quality of broccoli. This treatment resulted in faster curd initiation and maturity, larger curd diameter, and increased curd weight compared to the control plot. The findings indicate that the strategic use of organic manure can optimize broccoli production, suggesting a viable approach for improving crop outcomes in sustainable agriculture.

A Two-Way Street: How Are Yeasts Impacted by Pesticides and How Can They Help Solve Agrochemical Contamination Problems?

Plant-associated yeasts play significant ecological roles within the microbiomes of soils and pollinating insects. In previous studies, we have shown that yeasts can assist pollinators in locating nectar, which is crucial for their nutrition and the reproduction of many angiosperms. Additionally, in soil, yeasts can also act as plant growth promoters. Given the importance of yeasts for plant development, this review first explores the biochemical processes underlying the ecological role of these microorganisms in soil, insects, and in direct association with plants. Based on this premise, we discuss the influence of these relationships on agricultural production, the biological mechanisms through which pesticides negatively affect yeast cells, and how these microorganisms can tolerate widely used agrochemicals. Finally, we address key studies in the literature that support the potential of these microorganisms as bioremediation agents. In this context, we emphasize different experiences with both indigenous and genetically engineered yeasts, which may display enzymes in their surfaces that convert pesticides into less harmful or nontoxic molecules. Our review indicates that yeasts can be effectively harnessed in organic agriculture to promote plant growth and bioremediate contaminated soil or food.

Effect of organic farming on root microbiota, seed production and pathogen resistance in winter wheat fields

Societal Impact StatementAgricultural intensification is a major driver of biodiversity decline in agrosystems. For instance, it has been shown that conventional farming leads to a decline in soil microbial diversity and triggers a strong selection process, altering the functioning of the whole ecosystem. The present study shows that organic farming increases diversity and affects composition of crop plant microbiota, mostly as a response to field management and soil characteristics. Furthermore, crop plant microbiota influences crop production and resistance to pathogens. Therefore, agricultural practices affect plant performance through microorganism‐mediated changes, which may be important pillars of future sustainable crop production.Summary Agricultural intensification threatens biodiversity, but the effects of intensification on microorganisms are still overlooked despite their role in ecosystem functioning. Microorganisms associated with plants provide many services that affect plant growth and health. Organic farming is expected to strongly affect species composition, richness, and their interactions. We analyzed the effect of the farming system on endophytic microbial assemblages associated with winter wheat plants and plant performance in the field. We collected environmental data through farmer interviews, soil analyses, and plant inventories and analyzed root microbiota at vegetative and flowering stages. Organic farming increased fungal and bacterial diversity associated to wheat plants and affected species composition in most phyla. This effect was mostly due to soil characteristics and field management and a little to plant diversity in the field. Microbial responses were more pronounced at the late developmental stage, likely as a result of accumulative effect of management actions during plant development. Seed production and resistance to pathogens were related to specific phyla that are important for seed production and/or wheat resistance to septoriose. This work advances our understanding of how agricultural practices affect plant performance through microorganism‐mediated changes and supports the use of microorganisms as pillars of sustainable crop production.

Nanocząstki krzemu w zrównoważonym rolnictwie

The increasing population, shrinking arable land, and climate change prompt the search for new solutions in agriculture. In a sustainable approach, agriculture should be based on improving the quality and quantity of yields while maintaining biodiversity and protecting the natural environment. Nanotechnology, present in many areas of our lives, offers opportunities to support the development of sustainable agriculture on many levels. Among the numerous solutions and nanomaterials, silicon, which is a natural component of the ecosystem, deserves special attention. In its nanoparticle form, it acquires new, unique properties. This article focuses on the significant role of silicon nanoparticles in organic farming, with particular emphasis on their function as nanofertilizers. The authors analyze the impact of silicon nanoparticles on plant growth and development and their potential in mitigating the negative effects of abiotic stress factors caused by drought, salinity, and exposure to metals. Additionally, the beneficial effects of silicon nanoparticles on plants growing under biotic stress conditions induced by microorganisms such as bacteria and fungi are presented. The paper includes a review of original research results conducted in recent years in this area, as well as possible mechanisms and strategies of silicon nanoparticle action at the physiological, cellular, and molecular levels. The issue of the safety of using nanoparticles in agriculture and the prospects for their further use as a factor enhancing the resistance and productivity of crops are also discussed.

What lies ahead? Consumer expectations and wishes for organic animal farming: analyzing improvements to boost confidence in organic livestock farming

IntroductionTo meet the policy target of increasing the share of organic farming in the EU to 25% by 2030, it is also essential to increase consumer demand for organic products. For many consumers, animal welfare is one of the main reasons to buy organics. Trust is inherently important when purchasing organic food, as most of the standards on which organic farming relies, such as more space, cannot be verified by the consumer. Consumer trust in organic animal farming is therefore an important factor in the expansion of the market share of organic products. The aim of this study is to identify specific trust-building “changes” in organic livestock husbandry to strengthen consumer trust in the long term.MethodA total of eight regulations or practices, e.g. early cow-calf separation or regulations on the use of antibiotics, were assessed in terms of consumer awareness. Further described changes to these practices or regulations were ranked regarding their potential to improve trust in organic animal husbandry.ResultsThe results show that most of the regulations and practices mentioned were not known to consumers, confirming a low level of consumer knowledge about specific aspects of organic farming. All eight possible changes would increase consumer trust, at least somewhat.DiscussionThe ranking shows that, in particular, the practice of dam rearing and an even stronger limitation of flock sizes for poultry have the highest potential to increase consumer trust in organic animal husbandry and can therefore be recommended as important strategies to meet consumer demands in the future.

Promoting social sustainability and transforming foodways through alternative food spaces: a case study of Beijing farmers’ market

ABSTRACT Organic farmers’ markets have rapidly expanded in major Chinese cities as a response to food safety concerns, with the concept of “organic” serving as the driving force behind this movement. This study examines the Beijing Farmers’ Market, the first organic farmers’ market in mainland China, to explore its role in reconfiguring foodways and promoting social sustainability. The development of the Beijing Farmers’ Market is driven by the changing values, attitudes, and ideologies of both producers and consumers, that set them apart from the mainstream food system. While this study is situated within the broader context of food safety concerns that contribute to the emergence of such markets, it primarily focuses on how the market fosters trust and proactive relationships between health-conscious consumers and new farmers committed to safe food production. These dynamic connections are shaped by shifting lifestyles among both producers and consumers. This research highlights how food serves as a socio-spatial space for reconnecting people with nature and cultivating food communities, engagement and resilience.

Innovative organic nutrient management and land arrangements improve soil health and productivity of wheat (Triticum aestivum L.) in an organic farming system

IntroductionSoil health is vital for ecosystems, but excessive use of fertilizers, chemicals, and irrigation harms soil fertility, leading to reduced yields and degradation. Thus, exploring innovative land arrangements and nutrient management for staple crops such as wheat is essential. Organic farming offers a promising solution. This study hypothesized that an appropriate land arrangement, combined with split applications of farmyard manure (FYM) and liquid organic fertilizer, can enhance wheat productivity while also improving soil health. The objective of this study was to investigate the effects of different sowing methods and organic nutrient management practices on the productivity of wheat and soil health.MethodsThis study aimed to examine the impact of sowing methods and nutrient management practices on soil health and organic wheat productivity during the winter seasons of 2021–22 and 2022–23 at the Organic Farming Unit (Agronomy), Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment was arranged in a split-plot design, with three land arrangements/sowing methods in the main plot and eight nutrient management approaches in the subplots.ResultsConcerning different land arrangements, the furrow irrigated raised bed sowing (FIRB) method resulted in the maximum wheat yield (4.34 t ha−1) compared with flat row sowing and zero tillage sowing. With respect to nutrient management practices, 75% of the recommended dose of N (RDN) through the FYM was basal + 25% RDN with the 1st irrigation + Jeevamrut application at 500 L ha−1 during sowing, and the 1st irrigation + Panchagavya spraying at 5% during the booting stage resulted in the highest grain yield (4.47 t ha−1). Both the zero tillage and FIRB land arrangements resulted in better soil biological activities and microbial counts than did flat sowing. The results indicate that sowing wheat via the FIRB method, with the recommended nitrogen dose applied through split applications of FYM along with liquid organic manures such as Jeevamrut and Panchagavya, can be an excellent option for organic wheat cultivation. This approach can enhance both yield and soil health.ConclusionSeventy-five percent RDN through FYM as a basal + 25% RDN during the 1st irrigation + Jeevamrut at 500 L ha−1 during sowing and the 1st irrigation + spraying of Panchagavya at 5% during the booting stage effectively increased the growth and yield of organic wheat. With respect to land arrangements, both FIRB and zero tillage resulted in better growth, yield, and soil biological properties. The practical utility of this study is the optimization of split applications of FYM and land arrangements for organic wheat cultivation.

Impact of Cow Urine and Substrate Composition on Germination and Early Growth of Papaya (Carica papaya L.) Seedlings

Aim: This study evaluates the impact of cow urine and substrate composition on the germination and early growth of papaya (Carica papaya L.) seedlings, a critical phase for successful crop establishment. Study Design and Methodology: Conducted as a factorial experiment, it assessed eleven substrate or growing media combinations with and without cow urine treatment. Results: Results reveal that cow urine significantly reduces the time to 90 percent germination (T90) and enhances the germination index, indicating its stimulatory effect on seed metabolic activity. Treatments combining cow urine with substrates like soil, sand, vermiculite, cocopeat, and perlite (T10) showed the shortest T90 and highest germination index, suggesting cow urine accelerates germination. Additionally, cow urine application improved growth metrics such as relative growth rate (RGR) and total biomass accumulation, with T10 and T8 treatments yielding the highest values. Enhanced leaf relative water content (LRWC) and elevated proline levels in cow urine-treated plants indicate better water retention and stress resilience. Strong positive correlations were observed among proline content, RGR, and biomass accumulation, highlighting cow urine’s contribution to vigorous seedling growth and stress adaptation. Conclusion: The findings suggest that cow urine, in combination with optimized substrates, is a sustainable growth enhancer that promotes robust seedling development, suitable for organic farming practices aimed at papaya cultivation.

Efficacy of a polyherbal formula for controlling lice infestation in chickens and goats in backyard farming system in Romania

IntroductionLice infestation negatively impacts the welfare and productivity of domestic animals. This study aimed to evaluate the efficacy of a commercial polyherbal formula (PHF) containing Asarum europaeum, Lavandula angustifolia, Artemisia absinthium, and Tanacetum vulgare in managing lice infestations in chickens and goats within a backyard farming system in Romania.MethodsThe PHF was analyzed using high-performance liquid chromatography (HPLC) to determine its phytochemical composition. Chickens and goats with confirmed lice infestations were treated with the PHF by spraying it on the entire body. Treatments were administered three times at 14-day intervals for goats and at both 14- and 7-day intervals for chickens. Lice infestations were assessed in experimental groups before each treatment by counting the collected lice specimens.ResultsHPLC analysis identified key compounds in PHF: kaempferol (336.25 mg/ml), quercetin (88.38 mg/ml), epicatechin (43.98 mg/ml), and catechin (9.43 mg/ml). The PHF effectively controlled chewing lice in both chickens and goats, achieving a mortality rate of 76–98% in chickens and 96% in goats. However, the PHF was not effective against sucking lice in goats. A significant reduction in lice infestation (75% in chickens) was observed when the PHF was applied at 7-day intervals. No adverse reactions were noted in treated animals.DiscussionThe polyherbal formula demonstrated promising efficacy against chewing lice in chickens and goats, supporting its potential use as an alternative to chemical treatments, especially in organic farming settings. The findings suggest that this PHF could be a viable option for managing lice infestations in domestic animals, particularly where organic practices are prioritized.

Bio-fumigants as grain protectants in storage-A review

Agriculture is a global lifeline, especially in developing nations like India, where over 70% of the population relies on it. Protecting food grains from insect pests during post-harvest storage is crucial, particularly in regions lacking advanced storage technologies, leading to significant losses. Fumigation is still a key strategy for safeguarding stored grains. Methyl bromide (MBr) and aluminium phosphide (AlP) are the widely used chemical fumigants. Phosphine is used to a greater extent today, but there are frequent reports that several storage pests have developed resistance to this fumigant. The United Nations World Meteorological Organization declared methyl bromide as an ozone-depleting chemical in 1995, and hence, most of the developed countries have phased out its use. Therefore, there is an urgent requirement to develop alternatives having a possible replacement for these fumigants. Biofumigants are organic compounds derived from various plant sources, including essential oils, botanical powders, and plant residues or from microbial volatiles. They release volatile compounds toxic to pests but safe for humans and the environment, offering a sustainable pest management approach. Plants such as mustard and radish produce glucosinolates that release isothiocyanates, known for their pesticidal properties. Essential oils from eucalyptus, clove, and mint and volatiles from certain fungi and bacteria also exhibit fumigant properties. Biofumigants disrupt insect physiological and biochemical processes, leading to mortality or reduced reproduction. Studies showed their efficacy against pests like red flour beetle, lesser grain borer, and rice weevil. Unlike chemical fumigants, biofumigants do not leave harmful residues, preserving grain quality and aligning with organic farming practices. Shifting to biofumigants offers a promising, eco-friendly, and effective alternative for post-harvest pest management, ensuring food safety and sustainability

Site‐specific weed management on organic grain farms using variable rate seeding and data driven simulation

AbstractIntegrated weed management is integral to organic farming, with increased crop seeding rates as one effective weed suppression tactic. Precision agriculture, which uses guidance and sensor technologies to direct site‐specific management, could allow for targeted weed management using variable seeding rates. On farm precision experimentation (OFPE) can be used to predict site‐specific sub‐field weed biomass response to a range of varied crop and cover crop seed rates across whole fields to provide decision support directly to farmers. We used OFPE to compare five simulated precision seeding strategies to either maximize net return or minimize weed biomass. Five site‐years of OFPE data were collected from organic farms in Manitoba, Canada and Montana, USA. Seeding rate, weed biomass, crop yield, topographic variables and other remotely sensed data were collected on a 10‐m grid to model yield and weed response to seeding rates for each field. Simulated site‐specific variable seeding rate net returns improved upon farmer chosen uniform seeding rate net returns on average by $115 ha−1. When variable seeding rates were optimized to minimize weed biomass, simulated weeds were reduced on average by 10 kg ha−1 relative to the farmer chosen uniform seed rates. A combined variable rate approach which balanced net return and weed minimization improved both net return and weed suppression compared to farmer‐chosen seeding rates in every site‐year. The various seeding rate strategies represent different methods from which farmers can choose to implement OFPE to optimize sub‐field‐specific planting rates and to increase their field‐scale ecological knowledge.

Organic farming and semi‐natural habitats for multifunctional agriculture: A case study in hedgerow landscapes of Brittany

Abstract Finding more sustainable ways to produce food is a major challenge for humanity in the face of biodiversity extinction and climate change. Consequently, research on the ability of agroecosystems to provide multiple functions is growing. In this regard, the relative importance of organic farming and landscape‐scale measures for improving multifunctionality has recently been debated. We investigated the effects of farming system (conventional vs. organic) at field scale, total length of hedgerows in the landscape and their interaction on the multifunctionality of 40 winter cereal fields in Brittany (France). Our multifunctionality assessment integrated 21 indicators of five agroecosystem goods: biodiversity conservation, nutrient cycling and soil structure, pest and disease regulation, food production and socio‐economic performance. Many indicators of biodiversity conservation, pest and disease regulation, and socio‐economic performance were higher in organic than in conventional systems. However, indicators of nutrient cycling and soil structure did not improve and food production was much lower in organic systems. Total hedgerow length in the landscape had less influence than organic farming on indicators, although we observed positive interactions. Granivorous carabid abundance and semi‐net margin were highest in organic fields located in well‐preserved hedgerow landscapes. Synthesis and applications. Our study suggests that field‐scale organic farming is necessary to promote biodiversity conservation and associated ecological functioning in crop fields, whereas landscape‐scale preservation of semi‐natural habitats alone is likely insufficient. Preservation of hedgerows in the landscape brings additional ecological and socio‐economic benefits for organic systems without compromising agricultural production. More broadly, our results call for more ambitious research into the myriad possible combinations of farming practices and agri‐environmental measures at both field and landscape scales, to improve both below‐ground and above‐ground functioning.

Microbiome and nutrient dynamics of organic manures for precision NPK management in sunflower (Helianthus annuus L.)

AbstractOrganic manure plays an important role in soil fertility, microbial communities and sustainable agricultural strategies. In organic cultivation of crops, manures are mostly used without any calculation of the nutrients added to soil through their application. The quantities of nutrients supplied by the organic manures to the crop have to equalize the quantity of nutrients supplied by inorganic chemical fertilizers, in order to replace chemical fertilizers in organic farming. Since the organic manures release nutrients slowly into the soil over a period of time, the availability of nutrients to the standing crop requires precise estimation. In the present study, the amount of nutrients available in the soil as well as in all the manures was calculated. Moreover, the study included metagenomic analysis of different organic manures used by farmers and gives an insight to the role the microbiome plays in plant growth. Using a formula of STCR‐IPNS (soil test crop response integrated plant nutrition system), the quantities of different combinations of organic manures required to supply nitrogen, phosphorus and potassium (NPK) to sunflower plants were calculated. Organic manure combinations using animal bone meal, neem cake, farmyard manure and vermicompost recorded better growth and yield responses in sunflower plants compared to inorganic chemical fertilizers. Based on the estimation of NPK in the individual manures and in the soil, pot experiments were carried out to understand the effect of organic manures as well as inorganic fertilizers in the vegetative and reproductive growth of sunflower.

Influence of Farmer’s Income Level on Adoption of Agricultural Water Management Practices among Smallholder Farmers in Rongai Sub-county, Kenya

Water is a resource that cannot be replaced and can only be renewed if it is well managed. It is basic for all forms of life, for every aspects of socio-economic development, and for the maintenance of a healthy ecosystem. Agriculture is the biggest water user globally, accounting for 70 percent of total water withdrawals on average. There are different practices that can aid in managing water used for agriculture. Some of these agricultural water management practices are; rainwater harvesting, irrigation, organic farming, and use of drought resistant crops. Farmer’s decision to either adopt or reject these practices can be affected by several factors, some of which are socio-economic. Some of the socio-economic factors that may influence adoption of these practices include farmer’s educational level, income level and farm size. This study examined the influence of farmer’s income level on adoption of agricultural water management practices (Rainwater harvesting, Irrigation Drought resistant crops). Cross-sectional survey design was adopted, while proportionate and simple random sampling technique was used to obtain the respondents. The accessible population was 6,230 smallholder farmers from the target population of 26,804 smallholder farmers in Rongai sub county Kenya. The study was done in August 2023 to November 2023.The study included 120 smallholder farmers in Rongai Sub County. The study used questionnaire to collect data while binary logistic regression was used to analyze the data. The results indicated that adoption of agricultural water management practices is low, only 36% of smallholder farmers had adopted agricultural water management practices. The P value calculated for the 120 smallholder farmers was P=.033 which is < than .05 and therefore the null hypothesis was rejected concluding that in this study income level had statistically significant influence on adoption of agricultural water management practices among smallholder farmers in Rongai sub-county in Nakuru ,Kenya. The findings may help in emphasizing the necessity of assisting farmers in removing financial obstacles that may hinder adoption of agricultural water management practices.

This study emphasizes the need for creative ideas to improve agricultural sustainability. The present study advances the understanding of sustainable agriculture and offers practical advice to those looking to use greener methods of operation.

Agricultural trade deficit and its impact on Nepalese economy: A comprehensive review

International trade is essential for a country’s economic development and modernization, driven by the dynamics of imports and exports. This review comprehensively examines Nepal’s trade deficit and its impact on the national economy. Nepal’s trade landscape is characterized by a significant imbalance, with imports consistently surpassing exports, as evidenced by an import-to-export ratio of 10.26 in the fiscal year 2022/23. This trade deficit has profound implications for national income, Gross Domestic Product (GDP) growth, inflation rates, and foreign exchange reserves. This review identifies key factors contributing to the trade deficit, including geographical constraints, limited export diversification, heavy reliance on imports, infrastructural deficiencies, insufficient promotion and advertisement, political instability, low productivity, and dependency on remittances. This study underscores the critical need for export diversification as a strategy for mitigating trade deficits. Developing sectors with high potential such as tourism, information technology, hydropower, and organic farming are essential. Additionally, improving the quality and value addition of exported goods, expanding market access through proactive trade diplomacy, and supporting small and medium enterprises are highlighted as necessary measures. This study also emphasizes the importance of substantial investments in infrastructure, education, and skill development to enhance productivity and competitiveness. Promoting a national brand and leveraging digital marketing platforms can boost Nepal’s export profile. Sound monetary policies and a stable economic environment are crucial for addressing the adverse effects of exchange rate volatility and inflation. Political stability and a conducive business environment are vital to fostering long-term economic growth. The effective utilization of remittances through productive investments and reducing dependency on external aid are pivotal for achieving sustainable development. Through coordinated efforts across various sectors, Nepal can work towards reducing its trade deficit, enhancing economic stability, and achieving sustainable economic growth.

The Influence of Cultivation, Storage and Processing Technology on the Nitrate Content in Potato Tubers and Vegetable Crops as the Example of Ecologically and Hygienically Oriented Organic Agricultural Nature Management

The article presents the results of studies of the influence of organic and mineral fertilizers, as well as storage and processing technologies on the level of nitrates in potatoes, carrots and cabbage. The study demonstrated that in order to obtain the high yield of environmentally friendly vegetable crops, it is necessary to use biohumus at a norm of 8 t/ha or the combination of 6 t/ha biohumus and N35P35K40. This treatment can provide the potato yield of 420-440 c/ha, carrots 223-240 c/ha, cabbage 500-520 c/ha, while not exceeding the maximum allowable concentration (MAC) of nitrates. At a same time, studies have revealed that storage and processing of these vegetables under the required standard conditions can significantly reduce the amount of nitrates contained in the products. The work we have done shows an example of organic farming as the ecological and climatic project for carbon sequestration in soils, bioimprovement and bioprotection of soils, for increasing the yield and hygienic quality of the harvest. When processing the resulting vegetable products, toxic hazards to public health are eliminated and the ecological safety of the environment is ensured. Additional measures are needed to control the application of fertilizers to soils, the quality of agricultural products during collection, storage and processing.
