Enhancing Citrus Resilience: Strategies and Advances in Abiotic Stress Management: A Review

Citrus, a major global agricultural crop is highly valued for its nutritional benefits and widespread consumption. However, as a subtropical plant, citrus is particularly sensitive to abiotic stresses such as salinity, drought, waterlogging, nutrient deficiency, high irradiance and cold temperatures. These stresses pose significant challenges to citriculture, reducing yield and fruit quality. Traditional methods like rootstock selection and plant breeding have been used to improve stress tolerance to some extent. Recent advancements in genetic engineering and biotechnology have enhanced our understanding of the molecular mechanisms behind stress tolerance. Identifying and isolating specific genes and transcription factors have led to novel agricultural practices that economically benefit citriculture and mitigate the adverse effects of abiotic stress. This review paper emphasizes and summarises the citrus responses to abiotic stress and strategies developed to enhance stress tolerance in citrus plants.

Potato Berries as a Valuable Source of Compounds Potentially Applicable in Crop Protection and Pharmaceutical Sectors: A Review.

Potato (Solanum tuberosum) is a major agricultural crop cultivated worldwide. To meet market demand, breeding programs focus on enhancing important agricultural traits such as disease resistance and improvement of tuber palatability. However, while potato tubers get a lot of attention from research, potato berries are mostly overlooked due to their level of toxicity and lack of usefulness for the food production sector. Generally, they remain unused in the production fields after harvesting the tuber. These berries are toxic due to high levels of glycoalkaloids, which might confer some interesting bioactivities. Berries of various solanaceous species contain bioactive secondary metabolites, suggesting that potato berries might contain similarly valuable metabolites. Therefore, possible applications of potato berries, e.g., in the protection of plants against pests and pathogens, as well as the medical exploitation of their anti-inflammatory, anticarcinogenic, and antifungal properties, are plausible. The presence of valuable compounds in potato berries could also contribute to the bioeconomy by providing a novel use for otherwise discarded agricultural side streams. Here we review the potential use of these berries for the extraction of compounds that can be exploited to produce pharmaceuticals and plant protection products.

Novel Mito-Nuclear Combinations Facilitate the Global Invasion of a Major Agricultural Crop Pest.

A fundamental understanding of the underlying mechanisms involved in biological invasions is crucial to developing effective risk assessment and control measures against invasive species. The fall armyworm (FAW), Spodoptera frugiperda, is a highly invasive pest that has rapidly spread from its native Americas into much of the Eastern Hemisphere, with a highly homogeneous nuclear genetic background. However, the exact mechanism behind its rapid introduction and propagation remains unclear. Here, a systematic investigation is conducted into the population dynamics of FAW in China from 2019 to 2021 and found that FAW individuals carrying "rice" mitochondria (FAW-mR) are more prevalent (>98%) than that with "corn" mitochondria (FAW-mC) at the initial stage of the invasion and in newly-occupied non-overwintering areas. Further fitness experiments show that the two hybrid-strains of FAW exhibit different adaptions in the new environment in China, and this may have been facilitated by amino acid changes in mitochondrial-encoded proteins. FAW-mR used increases energy metabolism, faster wing-beat frequencies, and lower wing loadings to drive greater flight performance and subsequent rapid colonization of new habitats. In contrast, FAW-mC individuals adapt with more relaxed mitochondria and shuttle energetics into maternal investment, observed as faster development rate and higher fecundity. The presence of two different mitochondria types within FAW has the potential to significantly expand the range of damage and enhance competitive advantage. Overall, the study describes a novel invasion mechanism displayed by the FAW population that facilitates its expansion and establishment in new environments.

Avifaunal Diversity in Telangana State: A Case Study in Campus of Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad, India

Population Studies on different agricultural and other bird species were carried out at Students farm, College farm, Agri biodiversity park, and Agricultural Research Institute farm areas of Professor Jayashankar Telangana State Agricultural University (PJTSAU) Campus in semiarid region of Telangana state covering an area of about 36 Sq.km. for a period of eleven years (2012 to 2023). Population diversity of 92 species of different birds, and their distribution within the university campus farm areas were recorded. Important among them are 9 species namely: Blue rock pigeon (Columba livia), Spotted dove (Streptopelia chinensis), Rose ringed parakeet (Psittacula krameri),Common myna (Acridotheres tristis), House crow (Corvus splendens), House sparrow (Passer domesticus), Baya weaver bird (Ploceus philippinus), White throated munia (Lonchura malabarica), and Peafowl (Pavo cristatus) which depredate experimental field crops among them only few birds such as: Rose ringed parakeets, House crows, House sparrows, Pigeons, Baya weavers, Peafowls and Munias were serious bird pests to major agricultural and horticultural crops. The University farm areas were found to be the most preferred habitat for many of these birds, it could be due to availability of food, breeding, roosting and resting sites in abundance because of more agricultural croplands and agro forestry trees.

Hazard Assessment of Rice Husk Ash Generated from Rice Mills in Bangladesh and Way Forward to Overcome or Adopt the Hazards

Rice husk (RH), an agricultural waste, is abundantly available in Bangladesh, where the major agricultural crop is paddy consisting of 73.94 percent of all crops. Bangladesh produced 37.61 million metric tonnes of paddy in 2020-21, among which the volume of rice husk was 7.52 million metric tonnes. These are mainly used for low-value applications such as fuel in the parboiling of the rice mills, where the burning of rice husk produces more than 5 million metric tonnes of rice husk ash (RHA). The disposal in landfills or open fields causes serious environmental and human health hazards due to the low bulk density of RHA. As silicon dioxide (SiO2) has the highest amount of presence in the rice husk ash, long-term exposure can lead to lung cancer, silicosis, chronic obstructive pulmonary disease, or tuberculosis. This research primarily focuses on the feasible and cost-effective technology to convert the rice husk ash into environment-friendly valuable products namely amorphous silica, crystalline silica, and porous silica, apart from ash’s usage as construction material, pesticide, or soil improvement material.

Global market trends of grain and industrial crops

Analysing the dynamics of cultivation and consumption of major agricultural crops worldwide is crucial for understanding trends and planning for sustainable food production. It is important to have an integrated approach that involves collaboration between scientists, and farmers to implement sustainable practices. The analysis of global market trends of grain and industrial crops is the goal of paper. Methods of analysis, synthesis, generalisation, forecasting and databases of the Food and Agricultural Organization of the United Nations were used in the process of work. Such crops as wheat, corn, sunflower and flax were chosen for the study, because they are the major food needs of the world population. They are grown for grain (seeds), and flax is a plant of complex use, in which both the stem and the grain are important. They provide essential nutrients such as carbohydrates, proteins, fats, vitamins, and minerals that are crucial for human health. Cultivating these crops has been integral to the food security and economic stability of many countries, supporting large populations. As a result of the conducted research, it was found that India, China, the USA and Canada remain the largest producers of wheat in the world, but only India increases the cultivated area. A global trend to increase corn production has been identified. It was established that Ukraine remains an important producer of sunflower seeds. In addition, a gradual increase in interest in flax was noted. Although the increase in cultivated area can help to meet the growing demand for food products, the problem of using the agricultural plant residues also increases proportionally. This is an international problem, so its solution is of global importance. It has been founded that current research is focused on improving agricultural plant residues processing to obtain goods of various applications. The new knowledge received in the paper will allow working on the improvement of processing wheat, corn, sunflower and flax, which will be able to adequately meet the food needs of the growing world population without harming the environment

An Analysis of the Rice-Cultivation Dynamics in the Lower Utcubamba River Basin Using SAR and Optical Imagery in Google Earth Engine (GEE)

One of the world’s major agricultural crops is rice (Oryza sativa), a staple food for more than half of the global population. In this research, synthetic aperture radar (SAR) and optical images are used to analyze the monthly dynamics of this crop in the lower Utcubamba river basin, Peru. In addition, this study addresses the need to obtain accurate and timely information on the areas under cultivation in order to calculate their agricultural production. To achieve this, SAR sensor and Sentinel-2 optical remote sensing images were integrated using computer technology, and the monthly dynamics of the rice crops were analyzed through mapping and geometric calculation of the surveyed areas. An algorithm was developed on the Google Earth Engine (GEE) virtual platform for the classification of the Sentinel-1 and Sentinel-2 images and a combination of both, the result of which was improved in ArcGIS Pro software version 3.0.1 using a spatial filter to reduce the “salt and pepper” effect. A total of 168 SAR images and 96 optical images were obtained, corrected, and classified using machine learning algorithms, achieving a monthly average accuracy of 96.4% and 0.951 with respect to the overall accuracy (OA) and Kappa Index (KI), respectively, in the year 2019. For the year 2020, the monthly averages were 94.4% for the OA and 0.922 for the KI. Thus, optical and SAR data offer excellent integration to address the information gaps between them, are of great importance to obtaining more robust products, and can be applied to improving agricultural production planning and management.

Vertical Migration of Second-stage Juveniles of Meloidogyne enterolobii as Influenced by Temperature and Host.

Infective second-stage juveniles (J2) of Meloidogyne spp. migrate towards host roots, which depends on several factors, including root exudates and soil temperature. Although Meloidogyne enterolobii is a highly virulent nematode that affects major agricultural crops worldwide, there is limited ecological data about it. The objective of this study was to determine the J2 migration pattern vertically in 14-cm long segmented soil columns towards tomato (Solanum lycopersicum) and marigold (Tagetes patula) roots, each grown at two soil temperatures (20 or 26ºC). Bottomless cups with tomatoes or marigolds were attached to the top of each column; cups with no plants were used as untreated controls. Juveniles (1,000/column) were injected into a hole located 1 cm from the bottom of each column. The apparatuses were placed in growth chambers at 20 or 26ºC, and J2 were allowed to migrate for 3, 6, 9, or 12 days after injection (DAI). At each harvest, J2 were extracted from each ring of the columns and counted to compare their distribution, and root systems were stained to observe root penetration. M. enterolobii migrated over 13 cm vertically 3 DAI regardless of temperature, even without plant stimuli. The vertical migration was greater at 26ºC, where 60% of active J2 were found at distances >13 cm at 12 DAI. Temperature did not affect root penetration. Overall, a greater number of J2 was observed in tomato roots, and root penetration increased over time.

Documentation of Honeybees Flora and Blooming Period in Major Horticultural and Agricultural Crops Growing in Dryland Regions of Northern Karnataka, India

The goal of the present study was to determine the variety of nectariferous and polleniferous bee flora in the Koppal district of Northern Karnataka in order to enhance the bees' blooming season. When the blooming plants were visited, the honeybees' presence and foraging activity were documented. In a ten-minute interval when at least three honeybees visited the flowers, the plants were identified as bee foraging species. The various plant groupings that worker bees visit, including as fruit crops, vegetable cops, field crops, plantations, flower and ornamental plants, etc., are included in the identified bee flora. The detected flora was further divided into plants that yielded nectar, pollen, and both. A total of sixty-four crops were identified as forage crops. Of those, the Koppal district had plants that yielded nectar (14), pollen (13), and both (36), according to documentation. The major dearth times were discovered to be mid-April to mid-June, whereas the honey flow seasons were determined to be mid-December to mid-February and mid-July to mid-September. Based on the flora's availability, utility status, and duration of flowering, a floral calendar was established for the study area. The listed species (Syzygium, Cassia, Citrus, Pongamia, Azadirachta, Brassica, Areca, Cocos, Guizotia, Hilianthus, Albezia, Lagerstroemia, Polinathus, Sapindus, Tecoma) and others are some of the common and significant bee food plants.

Cotton farming in the different mesoregions of Mato Grosso and land use and cover between 2019 and 2021

Cotton is a major agricultural crop in Brazil, particularly in the state of Mato Grosso. Despite its significance, little is known about the spatial and temporal distribution of cotton farming and its environmental impacts in the region. This study aims to evaluate the presence of cotton farming in various mesoregions of Mato Grosso and assess soil use and coverage trends between 2019 and 2021. Utilizing satellite images provided by Mapbiomas, the dynamics of cotton cultivation were analyzed. The results reveal that the Northern Mesoregion has the largest cotton cultivation area, although it represents a small fraction of overall land use, with forest formations being predominant. The Northeast and Southeast Mesoregions also exhibit an increase in cotton areas, albeit on a smaller scale. Moreover, significant changes in land use are associated with livestock and soybeans, which dominate most studied mesoregions. The study concludes that cotton farming has limited expansion in Mato Grosso, presenting lower environmental impact compared to other human activities. Nevertheless, continuous monitoring of the crop and the adoption of sustainable soil and water management practices are recommended.

A taxonomic update on Tylenchorhynchus annulatus (Nematoda: Dolichodoridae), a widely distributed stunt nematode species

Summary The stunt nematode species, Tylenchorhynchus annulatus (Cassidy, 1930) Golden, 1971, is a widely distributed plant parasite found associated with various major agricultural crops. In the current work, a population of T. annulatus detected from a sugarcane field in Everglades, Florida, USA, was morphologically and molecularly characterised. A comparative study was also done including the stunt nematode populations identified morphologically and molecularly by different research groups as T. agri, T. annulatus or T. crassicaudatus from China, Indonesia, Iran, Korea, Niger, Nigeria, Tanzania and the USA, revealing highly similar morphology and overlapping morphometric data among the populations. However, these populations were found separated into two maximally supported clades in phylogenetic trees based on rRNA gene sequences (28S and ITS). One clade comprised populations from China, Indonesia, Iran, Nigeria, South Korea, Tanzania and the USA, and the other clade only populations from the USA. This study also strongly supported the view that T. crassicaudatus is a junior synonym of T. annulatus.

Efficacy of Salicylic Acid in Response to Plant Stress Tolerance, Growth and Productivity: A Review

Plant stress generated by various climatic and anthropogenic activities has exacerbated the degradation of agricultural systems and productivity throughout the developmental era, and it is currently recognized as the world's most significant and possibly deadly danger impacting crop plant economic output. Nonetheless, phytohormones have been found as a potent tool for minimizing the detrimental effects of stressors in agricultural plants in a sustainable manner. Salicylic acid (SA), one of the most important phytohormones, is required for the regulation of plant growth, development, ripening, and defensive responses. A lot of interest has been generated by SA's defensive mechanism. Major agricultural crops' ability to withstand stress has been said to be much improved. SA utilization is influenced by the amount of SA applied, the application method, and the state of the plants (such as their developmental stage and level of acclimation). In this review, we have focus on the efficacy of SA on mitigating various plant biotic and abiotic stress under adverse environmental conditions and its role on plant growth, development and productivity.

Agricultural exports of Ukraine in the conditions of war.

The article is devoted to the study of the problems and challenges of agricultural exports of Ukraine in the conditions of war. It was determined that before the beginning of the full-scale invasion, the country occupied a leading position in the world production of major agricultural crops (sunflower, rapeseed, barley, corn, wheat, soybeans). A comprehensive assessment of Ukraine's export positions in the world was carried out and the countries most dependent on the import of Ukrainian grain were identified. The dynamics of the domestic export of cereals, legumes (with products of their processing) and flour for the period from 2020/2021 MR to August 2023/2024 MR have been analyzed. The author has researched and systematized the problems of reducing the volume of export deliveries of Ukrainian grain to the world market. It is substantiated that part of the problems and challenges are macroeconomic in nature and complicate the development of the country's economy, distort market pricing mechanisms and reduce the competitiveness of domestic products. Among them is the risk of losing the country's reputation as a reliable supplier; loss of markets and trading partners; destruction of logistics and transport infrastructure; reduction of production volumes; change in demand; limiting access to resources; devaluation of the national currency, etc. A systematic analysis of the problems and challenges complicating agricultural export made it possible to single out the main ones: reduction in agricultural production volumes and loss of resource potential; limited financial resources; disruption of logistics chains. Special attention was paid to the problem of sea transportation, which before the beginning of the war provided about 95 % of agricultural exports. The dynamics of Ukraine's export volumes within the framework of the "grain initiative" during 2022- 2023 are analyzed. The role and significance of its implementation to mitigate the negative impact of Russia's military aggression on domestic agricultural exports is described. The reasons for the importance of sea transportation for Ukrainian exports have been determined: large volumes of supplies and their low cost. Emphasis is placed on the need to export by sea, even without the participation of Russia. The author researched the measures implemented by the Ukrainian government to support agricultural production and export and justified the need to develop a set of measures to stabilize and further develop the industry and restore the export of agricultural products. Among them are the following: reduction of bureaucratic barriers; state support for the development of logistics infrastructure, optimization of taxation and lending; adaptation of agricultural production to EU requirements; increasing the quality and safety of products in accordance with international standards; technological development and digitalization; restoration and transition of the agricultural sector to sustainable production. Key words: agricultural production, export, agricultural export, agricultural export problems, "grain initiative".

Soil microbiome analysis reveals effects of periodic waterlogging stress on sugarcane growth.

Sugarcane is one of the major agricultural crops with high economic importance in Thailand. Periodic waterlogging has a long-term negative effect on sugarcane development, soil properties, and microbial diversity, impacting overall sugarcane production. Yet, the microbial structure in periodically waterlogged sugarcane fields across soil compartments and growth stages in Thailand has not been documented. This study investigated soil and rhizosphere microbial communities in a periodic waterlogged field in comparison with a normal field in a sugarcane plantation in Ratchaburi, Thailand, using 16S rRNA and ITS amplicon sequencing. Alpha diversity analysis revealed comparable values in periodic waterlogged and normal fields across all growth stages, while beta diversity analysis highlighted distinct microbial community profiles in both fields throughout the growth stages. In the periodic waterlogged field, the relative abundance of Chloroflexi, Actinobacteria, and Basidiomycota increased, while Acidobacteria and Ascomycota decreased. Beneficial microbes such as Arthrobacter, Azoarcus, Bacillus, Paenibacillus, Pseudomonas, and Streptomyces thrived in the normal field, potentially serving as biomarkers for favorable soil conditions. Conversely, phytopathogens and growth-inhibiting bacteria were prevalent in the periodic waterlogged field, indicating unfavorable conditions. The co-occurrence network in rhizosphere of the normal field had the highest complexity, implying increased sharing of resources among microorganisms and enhanced soil biological fertility. Altogether, this study demonstrated that the periodic waterlogged field had a long-term negative effect on the soil microbial community which is a key determining factor of sugarcane growth.

Spatio-Temporal Distribution and Trends of Major Agricultural Crops in Romania Using Interactive Geographic Information System Mapping

This research study presents the spatio-temporal distribution of the main agricultural crops in Romania using a modern digitalisation technique, namely interactive GIS mapping. Interactive GIS mapping includes various features specific to the development of sustainable Romanian agriculture, including the arable area of Romania, information on the area (hectares) cultivated with corn, wheat, sunflower, and rape during the 1990–2018 period, the degree of mechanisation, the number of tractors, and information regarding the landforms, a natural factor in relation to cultivated surfaces. Agricultural land should be properly used based on its ability to meet the demands of consumers of traditional Romanian products with an ecological label, but also the needs of the local population, and, at the same time, to ensure the sustainability of the natural environment through the practice of ecological agriculture. The purpose of this research is to provide an overview of the current state of the main agricultural crops in Romania. From a theoretical but also practical point of view, this research presents, for the first time, a retrospective analysis of each county in Romania in terms of the geospatial distribution of major agricultural crops using interactive GIS mapping. Geospatial data were processed in ArcGIS Geographic Information System 10.7.2. The results of this study show that the most extensive cereal areas at the county level in Romania are corn and wheat. The largest areas cultivated with corn and wheat in 2018 were recorded in the Western Plain, the Romanian Plain, and the Moldavian Plateau. For wheat, increases were also recorded in the Dobrogea Plateau. The intensification of labour productivity and the promotion of the sustainability of the natural environment in Romania is presented through the main indicator (the number of tractors) of the degree of mechanisation of agriculture. The higher values of this indicator are in the counties of Bihor, Timiș, and Maramureș. Limitations in Romania’s agricultural data present substantial challenges to the sector’s development and sustainability. Addressing these challenges is essential for informed decision making, policy formulation, and effective resource allocation.

Influence of Grinding Degree and Screw Rotation Speed on Sunflower Oil Pressing Process

Sunflower is a major agricultural oilseed crop, and the Republic of Kazakhstan has been steadily strengthening its position as a producer of oilseeds. In this study, an oil pressing machine with two processes, including grinding sunflower seeds and pressing the obtained cake to separate the oil, is constructed. The experiment investigated the impact of different grinding degrees (hole diameters of plates of 5 mm, 4 mm, 3 mm, and 2 mm) and screw rotation speeds (ranging from 30 rpm to 250 rpm) on oil pressing efficiency. The study used sunflower seeds with an oil content of 45–47% and moisture of 7–9%. The results showed that increasing the grinding degree and screw rotation speed led to higher oil yield. The optimal condition was a grinding degree of 4 mm and a screw rotation speed of 60 rpm, resulting in the highest oil yield of 15.6 g/s. Additionally, the residual oil content of the seed cake decreased significantly as pressure increased during pressing, particularly with 4 mm grinding. Power consumption increased with higher screw rotation speeds and finer grinding degrees, indicating the influence of grinding components on energy demand. The cake density increased with higher screw rotation speeds and finer grinding degrees, highlighting the impact of grinding mechanisms on cake compactness. Moreover, the temperature of the cake rose with increased screw rotation speed and the presence of grinding sieves. These findings provide valuable insights into optimizing the sunflower oil pressing process, highlighting the importance of selecting appropriate grinding degrees and screw rotation speeds to maximize oil yield and pressing efficiency.
