Abstract:
Ratoon rice represents a viable means to enhance rice production efficiency in terms of both area and time. Nonetheless, the development of specific varieties tailored for ratoon rice has been hindered by the complexity of trait considerations required during breeding/screening processes. A pivotal step towards advancing ratoon rice breeding programs involves reducing the dimensionality of selection traits. In this study, we performed a comprehensive analysis exploring whether the yield of the main crop could serve as a predictor for ratoon crop yield, thereby simplifying the selection process

AbstractThis paper presents a new tool called the Space Data Generator, which is a parametric tool for organizing open spaces in rural areas. It can optimize the layout of buildings, solar panels, and agricultural planting spaces. While architects have been exploring ways to achieve net-zero carbon emissions in building design, it is equally important to attain a feasible carbon-neutral goal in rural areas. This is particularly crucial as 40% of the world's population resides in rural areas, and transitioning towards a more sustainable and efficient economy can bring about not only moral but also economic benefits through proper management [1].The Space Date Generator offers a powerful spatial planning approach for optimizing and planning agricultural resources on any given land. This innovative tool utilizes a combination of remote sensing to generate precise maps of the land, providing a comprehensive understanding of its terrain and potential agricultural resources. With this information, farmers and land managers can make informed decisions about crop selection, irrigation, and fertilizer application, among other factors. By using the Space Date Generator, they can optimize the use of available resources and maximize crop yields, ultimately increasing profitability and sustainability in agriculture [2].Overall, the Space Date Generator is a valuable tool for any farmer or land manager looking to make the most of their land and resources. Its ability to provide detailed and accurate data on the land's potential agricultural resources can help to streamline decision-making processes and ultimately lead to more efficient and sustainable land use practices. The Space data generator uses the collected site coordinate information, geographical status (including stones, lakes, and water patterns), and the planted plants’ price as input. Divide the site into small squares, then configure enough solar panels in the optimal sunlight area of the site to meet the user's needs, and then plant crops on the remaining land. The Space data generator will analyze the number of calories a household needs each year as a percentage. If there is a surplus, the excess food can be allocated to generate economic outcomes on the market. The land area at hand will be subdivided based on its sun ratio, which is a relatively straightforward process. However, we are also interested in determining the value of excess vegetation that may grow in the allocated space. In this regard, the Space Data Generator can prove to be a valuable tool, not only for this particular scenario but also in other types of agricultural settings such as those involving a mix of livestock and crops. Additionally, it may be possible to use this tool to calculate the optimal harvesting of various plant species at different points in the seasonal cycle.The Space Date Generator has the potential to offer valuable references for optimizing agricultural schemes. However, it must provide users with completely accurate results. Unfortunately, it currently cannot measure crucial factors such as soil type and moisture level, which are essential for agricultural planning. Despite this limitation, the Space Data Generator is a flexible tool that can be modified as research advances, allowing for more inputs to be added to improve its accuracy. Moreover, the Space Data Generator can provide guidance in various other areas based on the specific needs of the user. For instance, it can offer guidelines for traffic and urban design, among other demands. By leveraging this technology, users can access more precise and relevant information, enhancing their decision-making capabilities. As such, the Space Data Generator represents a valuable tool for various industries and sectors.Guidelines:

Abstract:
Sustainable agricultural practices involve a variety of approaches. The most important approached for sustainable agriculture development is crop diversification. It allowing the farmers to employ biological cycles to minimize inputs, conserve the resource base, maximize yields and also reduce the risk due to ecological and environmental factors. It serves as an important opportunity to augment income and employment generation for rural communities. Crop diversification promotes the interaction of beneficial soil bacteria, interrupts the disease cycle, and reduces the quantity of weeds. Crop diversification boosts land-use efficiency and crop output by improving the physical and chemical qualities of soil. Crop diversification shows a lot of scope to alleviating the problems such as resurgence of insects-pests and weeds, soil degradation, environmental pollution, soil salinity, decline farm profit and climate change. Crop diversification through crop intensification system enhanced the net returns, B:C ratio, and overall system productivity of a farm. In order to achieve the benefits of crop diversification farmers are shifting from low value low yielding crops to high value high yielding crops. Thus, crop diversification has the sound capacity for achieving the goal of nutritional security, income growth, food security, employment generation and sustainable agriculture development.

Abstract:
This study evaluated the competitive dynamics and yield performance of soybean-based intercropping systems on dryland Inceptisols. Conducted in Gunungkidul, Yogyakarta, Indonesia, from March to August 2020, the research compared four intercropping systems: upland rice-soybean, maize-soybean, maize-peanut, and maize-upland rice, against their respective monocultures. A randomized complete block design with five replicates was employed. Analysis to assess agronomic performance includes Land Equivalent Ratio (LER), Aggressivity (A), Competitive Ratio (CR), Relative Crowding Coefficient (K), and Actual Yield Loss (AYL). Results clearly demonstrated that maize-soybean intercropping was the most advantageous system for Inceptisols. While maize exhibited greater competitive dominance over soybean, as evidenced by Land Equivalent Ratio (LER) of 1.91, Actual Yield Loss (AYL) of 1.07, Aggressivity (A), and Competitive Ratio (CR), the intercropping system significantly enhanced overall productivity. Notably, maize-soybean intercropping achieved the highest yields. This study highlights the superior competitiveness and productivity of soybean when intercropped with maize on dryland Inceptisols, providing valuable insights for optimizing agricultural practices in these challenging environments.

Abstract:
In field experiences studies on growing field peas in single-component and mixed seeding with spring rape and white mustard were conducted in the Middle Urals. The crop capacity was increased by 10,8% as well as the total yield was increased by 2.3 times up to 2.14 t / ha by the use of spring rape as a supporting and compacting crop in sowng peas with a seeding rate at 0.6 million / ha. It was found out that crop productivity of peas was decreased by 19.4% when the seeding rate was established at 0.4 million / ha, and the crop productivity of spring rape remained at the level of pure sowing – 1.23 t / ha. The total yield, in comparison with the pure sowing of peas, increased by 2.1 times from 0.93 to 1.98 t / ha. Mustard is less suitable as a supporting crop, although it ripes earlier and does not thrive in contrast to spring rape. The total yield and ratio of land equivalents in a mixture with spring rape is higher than with mustard and ranged from 1.66 to 1.98. Peas accounts for the bulk of the total yield (LERab = 0.81...1.48). The coefficients of competitiveness and aggressiveness of the studied crops in mixed sowing indicate the dominant role of field peas in the pea-rape and pea-mustard agrocenoses. The awned and foliose morphotype of field peas when grown in a mixture with mustard showed themselves equally, their competitiveness and aggressiveness coefficients were in a close range – Crab = 2.37...4.57; CAab = 0.72...1.87. The awned morphotype of field peas had the greatest aggressiveness and competitiveness when cultivated in a mixture with spring rape – CRab=6.78...17.80; CAab = 3.35...5.79. The foliose morphotype of field peas occupied an intermediate position and had a good competitive ability with less aggressiveness towards spring rape – Crab = 2.64...2.66; CAab = 2.06...2.13.

Abstract:
Faba bean is an important pulse crop in terms of protein source, area coverage, and volume of annual production in Ethiopia. The aim of this paper is to assess the agronomic and crop physiology investigations in the past two decades in Ethiopia. The production limiting factors of this crop are low input usage, natural disasters, depletion of macronutrients, and unavailability of essential nutrients. Phosphorus is among the main limiting nutrients in soil systems in Ethiopia. Seed yield and biomass yield of faba bean were increased from 1338 to 1974 kg/ha and from 3124 to 4446 kg/ha when phosphorous was changed from 0 to 52 kg/ha, respectively at Holeta whereas application of 40 kg P ha − 1 resulted in higher grain yield (6323 kg ha−1) and 3303 kg ha−1 at Lemu-Bilbilo and Bore highlands, respectively. The highest grain yield of 32 kg ha−1 was obtained from the application of 92 kg P2O5 ha−1 at Sekela district while application of 46 kg P2O5 ha−1 resulted in a substantial increase in seed yield over unfertilized plots on vertisols of Ambo. On the other hand, the results suggest that using starter nitrogen from 0 to 27 kg/ha has marginally increased faba bean yield but, a farther increase of nitrogen has indicated deteriorate of yield at Arsi zone. Proper plant populations play a crucial role in enhancing faba bean production. Planting faba bean at 30 cm × 15 cm spacing gave the highest grain yield in Duna district while it was 30 × 7.5 cm at vertisols of Ambo University research farm. Significantly higher seed yield (4222 kg/ha) was observed in the 40 cm inter-row spacing as compared to 50 cm inter-row spacing, which gave the lowest seed yield per hectare (3138 kg/ha) on fluvisols of Haramaya University. Intercropping and crop rotation are cropping systems that can increase soil fertility and crop yield. Intercropping of faba bean with barley at Debre Birhan increased land equivalent ratio than both crops when planted as sole. An additional income of 18.5% and 40% was gained than planting sole faba bean and wheat, respectively at Kulumsa. Faba bean can fix about 69 kg/ha nitrogen in Northern Ethiopia. Generally, the current review results showed that only limited studies in organic and bio fertilizer, plant density, and cropping systems were done on faba bean in Ethiopia. Hence, studies regarding soil acidity, organic fertilizer, and secondary plus micronutrient impacts on faba bean production and productivity along soil types and weather conditions need great attention in the future in Ethiopia.

Abstract:
An important task of modern agricultural production is the formation of plant protein resources. Among various agricultural crops, legumes take a leading place in the raw material balance of the country, ensuring the production of protein products for food and fodder. In connection with the decrease in the production of livestock products, great attention should be paid to the problem of increasing the production of legumes rich in proteins. In the conditions of a steady tendency to narrow the list of main crops, it is important to maintain the species range of legumes, which ensures the growth of crop rotation productivity and reproduction of soil fertility. The potential yield of peas, fodder beans, chickpea and lentils under production conditions remains unrealized. The symbiosis potential of legumes with nodular rhizobia of the soil is often limited by a low level of nitrogen-fixing capacity or an insufficient number of bacteria in the germinating seed zone. Therefore, pre-sowing treatment of seeds with biological preparations based on strains of specific rhizobia should be an expedient agromeasure in the technology of growing leguminous crops. The purpose of the research was to analyze the elements of the technology of growing leguminous crops, namely determining the optimal doses of mineral fertilizers in combination with seed inoculation with bacterial preparations aimed at increasing the yield and quality of pea, fodder beans, chickpea, and lentils. The object of the research is leguminous crops (peas, fodder beans, chickpea, lentils). The subject of the research is the elements of the technology of growing legumes (mineral fertilizers and bacterial preparations based on nitrogen-fixing and phosphorus-mobilizing microorganisms). Relevance of the topic. In order to increase the effectiveness of the functioning of agrocenoses of leguminous crops, it is important to expand and deepen the knowledge of the study of individual technological elements of their cultivation. Until recently, the issue of the complex effect of agrotechnical factors, in particular mineral and bacterial fertilizers, on crop formation has not been solved fully. The influence of complex bacterial preparations, the components of which are nitrogen-fixing and phosphorus-mobilizing microorganisms, on the nitrogen-fixing capacity of leguminous plants (peas, chickpea, fodder beans, and lentils) at different levels of mineral fertilization remains insufficiently studied. It is necessary to identify agrotechnical measures that would contribute to the maximum realization of the productive potential of peas, chickpea, fodder beans and lentils. The results of the analysis of modern literary sources make it possible to reveal the all-round positive effect of complete mineral fertilizer, individual macro- and microelements, bacterial fertilizers on the activity of symbiotic systems and the productivity of legumes in different soil and climatic zones. Along with this, the issue of developing optimal criteria for the use of fertilizer remains not fully resolved, and this requires solving a number of issues, namely: whether it is advisable to use increased doses of mineral nitrogen in order to obtain high yields, turning leguminous crops into nitrogen users; what optimal doses of nitrogen fertilizers, with their corresponding ratio with phosphorus and potassium, should be applied under grain leguminous crops to ensure a high yield without inhibiting symbiotic nitrogen fixation; to what extent the applied high doses of mineral fertilizers are used by leguminous plants and what are the unproductive losses of nitrogen, which lead to environmental pollution with intermediate products of the transformation of mineral compounds. A scientifically based fertilization system is the basis for the formation of high and stable grain yields of leguminous crops, and the information mentioned above testifies to the insufficient study of the complex effect of agrotechnical factors on the quantity and quality of the crop.

Nutrients play a key role in maintaining soil fertility. Regular use of chemical fertilizers has great impact on soil infertility. Nutrient supply for soil sustainability is the most important step to maintain the fertility and integrity. The enrichment of soil with organic matter could reduce the content of bioavailable metal species as a result of complexation of free ions of heavy metals. The NPK ratio in the soil should be maintained for the good crop yield. There are various organic and inorganic materials available to mix with soil to enhance the soil fertility. Misuse of soil amendment can result not only in damage to crops but can also cause negative impact on soil fertility.

Abstract:
Hydroponics is a profitable, sustainable agricultural method and environmental friendly technology for growing plants without soil. It is the fastest-growing agriculture sector, rapidly gaining momentum and popularity, and could dominate food production in the future. Nutrient solution and its management are the cornerstone of a successful hydroponic system and are the most important determinant of crop production and quality, which is largely dependent on the extent to which plant nutrients are acquired from the nutrient solution. All nutrients in the solution in balanced ratio are supplied directly to the plants and the composition of the solution must reflect the uptake ratio of individual elements by the crop. A balanced supply of nutrients is a prerequisite for the efficient use of resources, and stabilization of the solution pH, electrical conductivity, O2 level, and temperature is essential for optimum crop yield in hydroponic systems. In this chapter, the composition of the nutrient solution, nutrient availability which is affected by many factors, and the management of the nutrient solution are discussed.

Food legumes, such as lentils, chickpeas, mung bean, soybean, peas, and beans, have been cultivated worldwide. They are providing essential nutrients and contributing to overall food security. Legumes are rich in protein, ranging from 20 to 45%, and contain essential amino acids, fiber, vitamins, and minerals, making them a nutritionally balanced food source. Biological nitrogen is fixed (90%) by legumes for sustainable agriculture. Meanwhile, the production of various leguminous crops is reduced due to low yield potential, the blend of biotic and abiotic stresses, and environmental changes. The continued cultivation of food legumes in existing cropping patterns is supported by their substantial nutritive values, advantageous cost-benefit ratios, and positive influence on soil health. The strategic integration of legumes into agricultural practices to boost productivity has gained significant attention in response to global food demand. Moreover, legumes play a pivotal role in rejuvenating soil organic matter and addressing problems when included in crop rotations with non-leguminous crops. Research findings that underscore the procedure of N2 fixation stand out as the most environmentally friendly for meeting the substantial nitrogen requirements. This will increase food production in an eco-friendly manner by reducing reliance on agrochemicals and preserving nutrient balances in the soil.

Abstract:
Potential environmental impacts of growing maize as monoculture lead to efforts focused on finding other potentially suitable crops or their combinations that could replace the pure maize cultures. The most frequent and most effective combination is a mixed crop of maize and legumes. The presented paper deals with the issue of the quality of post-harvest residues when growing maize in the system of mixed cropping. In the field experiment, yield and quality of post-harvest residues were studied during the growing season in the following variants: maize grown as monoculture and maize grown in th

Abstract:
Agate-like soil cover structures (ASCS) of leached chernozems are common in some regions of Russia with a total area of 425 242 km2 (the republics of Tatarstan and Bashkortostan, Orenburg, Samara, and Ulyanovsk regions). The term �agate-like structures� was proposed due to the fact that on remote sensing data they resemble a section of the Timan agate. The structures are formed on loamy and clayey Quaternary sediments with a thickness of 0.5-5 m, overlying Permian sediments (bedrock). It is possible to identify the location of agate-like structures within the framework of the theory of multi-t

Abstract:
According to the climate change in arid and semi-arid regions, saline water will be used in irrigation to mitigate the water gap between available water resources and the water demand. Using saline water to expand the irrigated area was followed by decreasing the crop yield due to osmotic potential, so an optimal indicator must be prepared to optimize the use of saline water. As climate changes effects water quantity and quality, the aim of this study is to mitigate the climate effects on water by improving the mathematical models and computer programs that are constructed to optimize the use

Dark-induced senescence could pose a major problem in export of various crops including cuttings. The assumption of this work was that ROS which is increased at a specific organelle can serve as a signal for activation of cell senescence program. Hormones which reduce senescence in several crops like gibberellic acid (GA) and possibly cytokinin (CK) may reduce senescence by inhibiting this signal. In this study we worked on Pelargonium cuttings as well as Arabidopsis rosette. In Pelargonium the increase in ROS occurred concomitantly with increase in two SAGs, and the increase persisted in isol
