Pengaruh Aplikasi Pupuk NPK Terhadap Pertumbuhan dan Produksi Tanaman Wortel (Daucus carota L.)

Indonesia is one of the tropical countries that has a variety of plants including vegetables and fruits. One that has the largest production is carrots (Daucus carota L.). Carrots are a type of shrub-shaped vegetable plant, which grows upright with a height of 30-100 cm or more. Carrots (Daucus carota L.) are a tuberous vegetable type plant that is usually reddish yellow or yellowish orange with a wood-like texture. The edible part of a carrot is the bulb or root. The plant stores food reserves in the bulb. The stem is short, has a taproot that changes its shape and function into a round and elongated tuber. The skin of carrot bulbs is thin and if eaten raw, it feels crunchy and slightly sweet. Here's a picture of a carrot plant. One way to increase the yield of carrot plants is by increasing soil productivity, using the addition of NPK fertilizer. This study used a factorial randomized group design (RAK). For accuracy in this study, it was repeated 3 times. namely: NPK fertilizer (N) with 3 levels, namely: N0 = Control, N1 = 15 g/plot, and N2 = 25 g/plot. From the ANOVA test results, the variance of treatments that have a significant effect is continued with the Duncan DMRT test at the 5% level. The results of the ANOVA test showed that the effect of NPK fertilizer treatment on plant height 21 hst and 28 hst, the number of leaves had no significant effect, but the observation of the diameter of the base of the tuber, the fresh weight of the plant per sample and the fresh weight of the plant per plot had a significant effect. Keywords: NPK fertilizer, NPK dosage, and carrot plants

The article examines the organization and provisioning of spare stores in the Yakutsk region during the 1840s, which played a crucial role in ensuring the region’s food security. These stores were part of a broader state system aimed at accumulating food supplies for public use during periods of crisis. The author investigates historical documents that describe contracts, supply logistics, and storage conditions, shedding light on critical issues such as delivery challenges, food spoilage, and supplier reliability. The analysis focuses on the measures implemented by authorities to address these challenges, emphasizing the significance of centralized management, quality control, and timely delivery. This study contributes to an understanding of the complex logistics of managing food reserves in the harsh and remote regions of the country, such as Yakutia.

Twenty-five years of the United Nations General Comment number 12 on the human right to adequate food – malnutrition continues to surge

The human right to adequate food is one of the most fundamental human rights crucial for the sustenance of the planet, and the prosperity of all people. It is firmly established in international human rights instruments and is clarified in the United Nations’ General Comment 12 (GC 12). However, deep vulnerabilities and deprivation of the right to adequate food in the form of hunger, food insecurity and malnutrition have persisted in many parts of the world. The climate-induced disasters also continues to devastate many communities, thereby depriving them of their rights including adequate food. This commentary provides a broader perspective on the 25 years of the GC 12 to stimulate further debate and actions to entrench human rights, especially the right to adequate food, at the centre of the food systems transformation and overall sustainable development agenda. This year 2024, marks 25 years of the Global Compact 12 on the human right to adequate food. While it is an important opportunity to celebrate this great achievement of engraining this right into the wider sphere of global reference at the United Nations level, the domestication in countries into actions that concretely address the problem of hunger and malnutrition has been slow in many countries. The world is now faced with the grim realities of starving populations arising from unnecessary and unjust wars, and food continues to be used as a weapon of war against international law and human imagination. Worse still, in the current environment of climate change and its adverse effects on food systems, SDG2 (Zero hunger by 2030), seems unrealistic. Finally, it is no longer a question of providing carbohydrates, as the need to address quality, safety, nutrition and cultural acceptability is ever so pressing. Going forward, there is a need to accelerate advocacy efforts, research and policy formulation that fully operationalise GC 12 in country-level food systems and nutrition interventions. Realization of the right to adequate food benchmarks in GC 12 should certainly be the penultimate of such interventions as strategic food reserves, poverty and hunger reduction programmes, humanitarian disaster preparedness, contingency funding, social protection and child care among others.

The sugar palm plant is a potential plant because almost all parts of the sugar palm tree are useful and can be used for various needs,starting from the roots,stems,leaves, fibers and its products (nira, starch or flour, and fruit)the main product of the sugar palm plant is nira which is processed into various products, such as sugar,alcohol,and biofuel.Sugar palm plants generally live in tropical environments).Sugar palm is a type of palm plant that has a very wide distribution in Indonesia, with an area of 62,009 ha, consisting of Sumatra with an area of 15,802 ha, Java 19,757 ha, Bali 587 ha, NTB 1,816 ha, Kalimantan5,401 ha, Sulawesi16,951 ha and Maluku 1,696 ha. Sugar palm seeds consist of seed coat (testa), endosperm, and embryo, and the embryo becomes a food reserve for apokol. Apokol is a white coral tissue where shoots and roots grow, appearing 2-4 weeks after planting.The development of the potential of sugar palm has problems related to the availability of sugar palm seeds which are currently still hampered because the nature of sugar palm seeds is waterproof so that it will inhibit the ability of the seeds to germinate. The growth process of sugar palm beginswith the emergenceapokol after that shoots will appear in the germinations. But no ideal apokol was found thatlong in determining the process of shoot growth. This study was conducted where the results of the data on apokol diameter, apokol length, root length and number of roots were obtained. Keywords : apocol, anatomy, bud

Biochemical Changes and Germination Response of Indian Sandalwood (Santalum album L.) Seeds Subjected to Biopriming Techniques and Variable Post-priming Storage

Understanding of the storage behaviour of endangered plant species such as Indian Sandalwood, Santalum album L. is important for successful conservation. We tested biopriming method with five biopriming agents (e.g. Effective microorganisms; Plant growth promoting rhizobacteria (PGPR-I and PGPR-II); Pseudomonas fluorescens and Piriformospora indica) with four uniform durations of treatments viz. 2, 4, 6 and 8 days. Hydropriming was also performed with similar condition for comparison of seed performance. The study examined the biochemical changes that occur in Sandalwood seeds during different post-priming storage periods (0, 30, 60, 90 days) to assess the efficacy of biopriming techniques on seed germination and health. Biopriming with Pseudomonas fluorescens for eight days recorded the highest germination percentage (70.67%) and the highest germination rate index (0.84). Longer durations of PGPR-I and Piriformospora indica treatment (6-8 days) lowered the imbibition period and mean germination time while increasing the germination rate. After a post-priming storage period of 30 days, only EM and Pseudomonas fluorescens treated seeds germinated while all other treatments failed to germinate. Absence of germination in any biopriming group at 60 and 90 days storage period indicated that the sandal seeds deteriorated over extended storage period. The reduction in seed viability of sandal seeds was consequent to the changes in the biochemical characteristics and action of enzymes (α and β amylases) involved in seed food reserve depletion and loss in membrane integrity.

An integrated food management framework: A preventive measure for food scarcity during the Prabowo Subianto administration

The Food and Agriculture Organization (FAO) reported in 2024 that Indonesia is at risk of facing a future food crisis if adequate food supply is not ensured. A critical aspect of food management in Indonesia lies in its management systems. Thus, this study aims to review the extent to which food management under the Joko Widodo administration has been integrated to address food shortages. Further, this study will develop an integrated food management system as an alternative to prevent food scarcity during the Prabowo Subianto administration. The methodology involves a literature review and in-depth interviews with stakeholders involved in managing the national food reserve. Findings indicate that food management in Indonesia remains fragmented and lacks integration between central and local governments, hindering effective food management during periods of scarcity. Based on an online website, the proposed integrated food management framework aims to simplify national food management and prevent food shortages.

Green Light Drives Embryonic Photosynthesis and Protein Accumulation in Cotyledons of Developing Pea (Pisum sativum L.) Seeds

Photosynthesis is a vital process for seed productivity. It occurs in the leaves and provides developing seeds with the necessary nutrients. Moreover, many crops require photochemical reactions inside the seeds for proper development. The present study aimed to investigate Pisum sativum L. seeds at the middle stage of maturation, which is characterized by the active synthesis of nutrient reserves. Embryonic photosynthesis represents a crucial process to produce cells’ NADP(H) and ATP, which are necessary to convert sucrose into reserve biopolymers. However, it remains unclear how the pea embryo, covered by a coat and pericarp, receives sufficient light to provide energy for photochemical reactions. Recent studies have demonstrated that the photosynthetically active radiation reaching the developing pea embryo has a high proportion of green light. In addition, green light can be utilized in foliar photosynthesis by plants cultivated in shaded conditions. Here, we addressed the role of green light in seed development. Pea plants were cultivated under red and blue (RB) LEDs or red, green, and blue (RGB) LEDs. A Chl a fluorescence transient based on OJIP kinetics was detected at the periphery of the cotyledons isolated from developing seeds. Our findings showed that the addition of green light resulted in an increase in photochemical activity. Furthermore, the mature seeds that developed in the RGB module had a significantly higher weight and more storage proteins. Using a metabolomics approach, we also detected significant differences in the levels of organic acids, carbohydrates, nucleotide monophosphates, and nitrogenous substances between the RB and RGB conditions. Under RGB light, the cotyledons contained more ornithine, tryptophan, arginine, and aspartic acid. These changes indicate an impact of green light on the ornithine–urea cycle and polyamine biosynthesis. These results allow for a deeper understanding of the photochemical processes in embryos of developing seeds grown under a low light intensity. The photosynthetic system in the embryo cell adapts to the shade conditions by using green light.

The use of aquatic bioresources as a factor in ensuring Ukraine’s food security: legal aspects

The article is dedicated to the study of the legal aspects of using aquatic bioresources in Ukraine and the impact of their usage on ensuring the country’s food security. It is argued that the issue of proper legal regulation of the use of aquatic bioresources is becoming increasingly relevant today. Attention is given to both legislative and scientific approaches to the issue of legal regulation of Ukraine’s food security. The necessity of adopting a separate law titled «On the Fundamentals of Food Security of Ukraine» is emphasized. It is noted that the state’s food policy should aim for the highest degree of self-sufficiency, as the quality and quantity of consumed food products directly impact the nation’s health, life expectancy, work capacity, and intellectual potential. The article examines the legal grounds for the usage of aquatic bioresources. The impact of the fishing industry on ensuring Ukraine’s food security is analyzed, with the conclusion drawn that the country’s food security largely depends on the state of aquatic bioresource usage. The level of fish consumption and its processed products serves as an indicator of the population’s food security, which should be maintained at a level conducive to physiological needs. It is stressed that the development of the fishing industry is one of the most important tasks for ensuring the post-war recovery of the country. The article identifies aquatic bioresources as a strategic state food reserve in the current context. The artificial reproduction of valuable fish species is aimed at both supporting aquatic ecosystems and building industrial stocks. The author asserts that today, food security is a condition for maintaining the state’s sovereignty, supporting high levels of public health, and developing the country’s economy. Emphasis is placed on the fact that the use of aquatic bioresources is crucial for the country in terms of ensuring food security, improving economic conditions, saturating the domestic market with quality food products, increasing employment and welfare, as well as preserving biodiversity and effectively using water and hydrobiological resources.

Neutrophils on the mast cell menu.

A recent article in Cell reported a new peculiar interaction between mast cells and neutrophils. Upon IgE/Ag-mediated degranulation, mast cells (MCs) produce leukotriene B4 (LTB4), which attracts migrating neutrophils. Some neutrophils are able to establish close contact with MCs and end up trapped inside the MC, forming a cell-in-cell structure. While the neutrophil eventually dies inside the vacuole, the MC benefits from the remains of its prisoner, using it as a nutrient reserve and reusing its antimicrobial weapons.

Determinan Keputusan Petani Mengelola Usahatani Padi Di Lahan Suboptimal

The conversion of paddy fields seriously impacts rice availability for national food reserves, so the government is implementing a sub-optimal land extension program. Indonesia has suboptimal land that has the potential to become a national rice barn if appropriately managed. The types of suboptimal land most widely used in rice cultivation are lowland and tidal swamps, where the community can work. This research analyzes the determinants of rice farmers' decisions in managing suboptimal land. This research was conducted in West Tanjung Jabung Regency, Jambi Province, with a sample of 90 rice farmers. Data were analyzed using the multinomial logistic regression method. The determining factors are seen from the demographic and economic aspects. The research results show that factors that significantly influence farmers' decisions to choose tidal land from the demographic aspect are age and farming experience; from the economic element are the number of family dependents, land ownership status, and non-farming income. The significant determining factors in farmers' decisions to manage lowland swamp land from the demographic aspect are age and farming experience, and from the economic element are the number of family dependents and non-farming income. From the research, recommendations that can maximize the use of suboptimal land are increasing promotion and education to the community about rice cultivation on suboptimal land, providing easy access for farmers to rent land, and it is hoped that farmers will continue to have non-farming income to balance household needs and procurement of capital and farming input.

The prospects of the food and agro-food sector in the structure of the economic management system are related to global and national trends in the development of agriculture, food industry and effective management of these industries. The growing demand for environmentally friendly products forces companies and farmers to implement sustainable production methods. This includes reducing greenhouse gas emissions, using water and resources efficiently, and moving to organic agriculture. Environmental standards are becoming important in ensuring the competitiveness of products on the domestic and international markets. Automation and digital technologies are rapidly penetrating the agri-food sector. Precision farming technologies, artificial intelligence, drones and satellite systems allow for increased production efficiency, improved resource management and reduced costs.In addition, digital platforms help to optimize supply chains and improve interaction between market participants. There is an increasing focus on food safety due to increased regulation by governments and international organizations. This requires agri-food businesses to invest in quality control systems and meet international standards such as HACCP. The increase in the export of food and agricultural products is an important factor in the economic development of many countries. This requires diversification of sales markets, improvement of logistics infrastructure and adaptation to the requirements of foreign markets.In addition, supporting local producers through government subsidy programs can strengthen the domestic market. The concept of a closed-cycle economy involves minimizing waste and maximizing the use of resources at each stage of production. In the food sector, this may include using waste as raw material for fertilizer or energy production. Small and medium-sized businesses in the agri-food sector can play an important role in ensuring food security and sustainable development of rural areas. Government support programs, access to finance and educational programs can help strengthen this sector. Climate change directly affects the food sector, causing unpredictable weather conditions that can reduce harvests and increase the risk of production losses. Adapting to these changes requires the introduction of new technologies, genetically modified crops, and risk management programs. At the global level, more and more attention is being paid to food security - ensuring a stable food supply. This includes the development of the agro-industrial complex to reduce dependence on imports, increase food reserves, and develop infrastructure for storage and transportation

Impact of the Political Risk on Food Reserve Ratio: Evidence Across Countries

Impact of the Political Risk on Food Reserve Ratio: Evidence Across Countries

The Role of Mycorrhizal Fungi in Orchids Mycobiont and Orchids.

In nature, orchid plants are obligate myco-heterotrophs, and rely on mycorrhizal nutrient resources to grow and sustain in the wild, until they become physiologically active photosynthetic plants. Their seeds lack nutrient reserves and receive the necessary carbon from symbiotic fungi during germination. A mycorrhizal fungus provides nutrients, especially sugars, as well as water to the corresponding host plant. The range and distribution of orchid mycorrhizal fungi influence the survivability of orchid populations in their natural habitats. Mycorrhizae form symbiotic connections with the parenchymatous tissues of the roots of orchid plants. The objective of this study was to examine the presence of mycorrhiza in the roots of Aerides multiflora during the vegetative phase Methods: Fresh roots were hand-sectioned, and thin sections were observed under the microscope to locate the presence of mycorrhiza. Simultaneously, to observe the expansion of mycorrhiza in the cortical region. During the vegetative phase of plant growth, a peloton-like structure forms within the cortical region of the orchid roots. Mycorrhizae was observed to be distributed throughout the cortical layer of the root. This communication reviews the role of mycorrhiza in orchid plants.

The Influencing Mechanism of Household Food Purchasing Behavior and Household Reserve Efficiency under Non-Normal Conditions

Family reserves are an important part of national reserves, and how to do a good job in family reserves is a common concern of the government and society. Under the non-normal conditions of major accidents and disasters, wars, plagues, social unrest, etc., urban food supply mainly depends on external supply guarantee, and urban residents’ risk perception is more sensitive. Based on the Theory of Planned Behavior and Norm Activation Model, this study constructs an analytical framework for the risk perception, perceived behavior control, and family reserve efficacy of urban residents under non-normal conditions from the perspectives of rationality and sensibility, self-interest, and altruism. The perceived behavior control of household food reserves in non-normal conditions is affected by risk perception, subjective norms, and personal norms. On this basis, countermeasures and suggestions are put forward: Urban residents should strengthen their sense of risk and responsibility for storing food at home, reserve food appropriately, and develop a good habit of family saving. On the other hand, it is necessary to pay attention to personal norms, reduce the negative impact of subjective norms on residents, and avoid excessive food storage and food waste.

Strategies of invasive snail Pomacea canaliculata during hibernation in rice fields of south China: effects of body size, sex, and soil depth.

The invasive freshwater snail Pomacea canaliculata is an agricultural pest with a certain level of tolerance to abiotic stress. After the harvest of late rice, the snails usually burrow themselves into the soil surface layers to overwinter and pose a renewed threatto rice production in the following year. Revealing the response of snails to environmental stresses is crucial for developing countermeasures to control their damage and spread. In this study, we conducted a 120-day in situ experiment during the winter to investigate the survival and physiological changes of hibernating snails in 0-5 and 5-10 cmsoil depths, aiming to explore their overwintering strategies. Our results showed that 73.61%, 87.50%, and 90.28% of male, female, and juvenile snails survived after hibernation for 120 days in 0-10 cm soil depth, respectively. The differences in survival rates based on sex and size of snailspotentially reflect the countermeasures of snails to rapidly reproduce after hibernation. Simultaneously, the hibernating snails exhibited the ability to maintain a certain level of body weight. During this period, the snails increased their antioxidant enzyme activities to cope with oxidative stress, and enhanced their lipid storage. The hibernation survival of snails was not significantly affected by different soil depths, indicating that they have the potential to hibernate into deeper soils. Furthermore, snails were capable of increasing their contents of bound water and glycerol to cope with sudden cold spells during hibernation. Our findings emphasize the adaptive changes of P. canaliculata snails overwintering in paddy soils. In future studies, the vulnerabilitiesof P. canaliculata during hibernation (e.g. shell characteristics, nutrient reserves, and dehydration tolerance, etc.,) should be investigated to develop effective control methods for this period. © 2024 Society of Chemical Industry.

The Effect of Ecological and Physiological Adaptation of Food Crops on Food Security in the Banyumas Highlands Region

This study aims to analyze the influence of ecological and physiological adaptations of food crops on food security in the highland area of Banyumas Regency. The research area includes Baturaden, Kedungbanteng, and Cilongok Districts, which are known to have a surplus of rice food reserves. Ecological adaptation includes how food crops adapt to specific environmental conditions at high altitudes, while physiological adaptation includes plant responses to factors such as temperature, humidity, and soil type. The data used in this study came from the Central Statistics Agency of Banyumas Regency in 2021. The results show that food accessibility, measured through physical and social access, has a significant correlation with food security. Physical and social access were significantly correlated with food security, with significance values of 0.046 and 0.017, respectively. The study concluded that the ecological and physiological adaptations of food crops play an important role in supporting food security in the Banyumas highlands, and that increased physical and social accessibility can improve food security stability in the region. Local governments need to focus on providing facilities and infrastructure that support food accessibility to ensure sustainable food security in the highlands.

Cassava (Manihot Esculenta Crantz) Processing as Enbal to Support Food Security in Wab Village, Hoat Sorbay Subdistrict, Southeast Maluku Regency

This study aims to explore the process of processing cassava (Manihot esculenta Crantz) into enbal and its contribution to food security among the community in Wab Village, Hoat Sorbay District, Southeast Maluku Regency. The method used is qualitative, with data collection techniques through observation, interviews, documentation, and questionnaires. The results of the study indicate that the cassava processing process involves several stages, from cleaning, rinsing, grating, pressing, to air-drying. Farmers use simple tools and traditional methods passed down through generations. The processed cassava is stored in open places such as trays and sieves (Sivat) and is immediately processed to prevent spoilage and mold. The quick and efficient production of enbal helps maintain the quality and taste of the final product. The study also found that the abundance of cassava in farmers' fields ensures a stable supply of food reserves, reduces dependence on external food sources, and supports the economic stability of farmers' families. In conclusion, the cassava processing method into enbal applied by farmers in Wab Village not only supports local food security but also strengthens the local economy through optimal and sustainable utilization of local resources.

Impacts of the cyromazine emergence inhibition procedure of Bactrocera dorsalis on Fopius arisanus: implications for the biological control of diptera pest.

Fopius arisanus (Sonan) is an important egg-pupal endoparasitic wasp of Bactrocera dorsalis (Hendel). As traditional method of sorting nonparasitic B. dorsalis from parasitic wasps is labor-intensive, requires specific equipment and poses the risk of spreading fertile hosts, the development of a more convenient, economical and safe sorting procedure is important. The optimal cyromazine emergence inhibition procedure (CEIP) involved facilitating the pupation of B. dorsalis mature larvae (Bdml) in 3 mg kg-1 cyromazine sand substrate (CSS) for 48 h. When the Bdml that had been exposed to F. arisanus during the egg stage were treated with 3-7 mg kg-1 CSS for 48 h, no negative effects on the emergence parameters of parasitoids were observed. Treatment with 3-4 mg kg-1 CSS had insignificant effects on the biological and behavioral parameters of F. arisanus. However, treatment with 5-6 mg kg-1 CSS adversely affected the fecundity and antennating activity of the wasps; specifically, 6 mg kg-1 CSS negatively affected the lifespan and flight ability of wasps. Fortunately, no transgenerational effects on these parameters were observed in the progeny. Regarding the nutrient reserves of both sexes of F. arisanus, significant dose-dependent effects were observed. Moreover, 5-6 mg kg-1 CSS significantly reduced the protein and carbohydrate content in F. arisanus; in particular, 6 mg kg-1 CSS notably reduced the lipid content. CEIP provides a more flexible, economical and safe mass-release program for F. arisanus. In addition, it has profound implications for the biological control of other dipteran pests. © 2024 Society of Chemical Industry.
