Background: Identification and development of new varieties are important elements of improving and sustaining soybean yield, especially in arid and semi-arid regions, including Iran. Methods: The study aims to investigate the effect of different levels of low irrigation on yield and qualitative characteristics of different soybean cultivars (Dezful 504, Sahar, Telar, Tekavar, Zan and Sari) under water stress (90%, 70% and 50% of the field capacity), under the climatic conditions of Jiroft during two years (2020 and 2021). This experiment was carried out as a split plot based on a randomized complete block design with 18 treatments and 3 replications at the farm of South Kerman Agricultural Research and Training Center and Natural Resources. Result: The highest qualitative characteristics and performance were in the cultivar 504 Dezful. Examining the results related to the interaction effect of irrigation ´ variety showed that the variety 504 Dezful under the conditions of 90% of the field capacity has the highest amount of grain yield (3748 kg/ha), oil yield (916.41 kg/ha) and protein yield (1351.53 kg/ha). Also, this cultivar was superior to cultivars in all levels of low irrigation. In general, and according to the obtained results, Dezful cultivar 504 was identified as the most resistant cultivar and Sari cultivar as the most sensitive cultivar to drought stress.

Background: Groundnut (Arachis hypogaea L.) holds significant importance as a staple food legume and a key economic crop, serving as a valuable source of edible oil and protein in India. However, its full yield potential is often hampered by excessive vegetative growth, which leads to suboptimal yields. With this background, a field experiment was conducted at the Perunthalaivar Kamaraj Krishi Vigyan Kendra in Puducherry during 2020 and 2021. The objective was to investigate the influence of different concentrations and timing of paclobutrazol (PBZ) application on the growth and yield of groundnut. Methods: The experiment was laid out in a split-plot design with three replications, six main plot treatments (Including PBZ concentrations of 25, 50, 100, 150, 200 ppm and a control) and three sub-plot treatments (Involving single sprays at 30 days after emergence (DAE), single sprays at 50 DAE and double sprays at 30 and 50 DAE). Result: The results revealed that the application of paclobutrazol at different concentrations had a positive effect on reducing plant height during the later stages of growth, particularly when a double spray was applied at 30 and 50 DAE. Notably, the application of paclobutrazol at a concentration of 200 ppm in groundnut cultivation proved to be economically viable, resulting 29% increase in pod yield compared to the control group. Specifically, PBZ at 200 ppm, with a double spray, significantly boosted the total pod yield to 2724 kg ha-1. Furthermore, the correlation and regression analyses indicated a positive relationship between growth and yield.

Background: The rise in unprecedented pressure of producing enough food for an ever-growing human population resulted in the use of considerable amounts of agrochemicals in crop production. To overcome this, inclusion of annual pulse crops such as cluster beans (Cyamopsis tetragonoloba L.) in cropping systems is an alternative technique for enhancing output while minimising environmental impact. Therefore, to assess the influence of different crop production systems on yield, quality and soil fertility attributes of fennel (Foeniculum vulgare L.)-cluster bean (Cyamopsis tetragonoloba L.) crop sequence, a long term field experiment was conducted. Methods: A field experiment was conducted on fennel (Foeniculum vulgare L.) cluster bean (Cyamopsis tetragonoloba L.) crop sequence under AI-NPOF Project during 2016-17 to 2020-21 at ICAR-National Research Centre on Seed Spices, Ajmer (Rajasthan), India. The experiment was laid out as a factorial design based on randomized complete blocks (RCBD) with three replications. The first factor consisted of six production systems viz., (PS1) - 100% organic, (PS2) - 75% organic + 25% innovative practice (Compost extract, cattle urine), (PS3) - Integrated (50% organic + 50% inorganic), (PS4) - Integrated (75% organic + 25% inorganic), (PS5) -100% inorganic nutrient sources and (PS6) - State recommendation] including fennel (Rabi season) - cluster bean (Kharif season) cropping sequence, whereas the second factor included the environment over the period. Result: The outcomes of study revealed that production system (PS4) - Integrated (75% organic + 25% inorganic) resulted in the maximum seed yields and yield attributes of cluster bean (1501.87 kg ha-1) and fennel (1970.19 kg ha-1). The study shows that the production system (PS4) had a 17.29 and 30.75% increment of protein as compared to PS5 and PS1 in fennel and cluster beans, respectively. Under production system PS1, the per cent increment of soil organic carbon (~25.2%) and readily available N (~9%), P (~38.5%) and K (~Non-significant) were noted over the years respectively, compared with production system (PS5). A significant positive association was observed between fennel and cluster bean grain yield and soil organic carbon (P less than 0.01) and the Shannon-Wiener indexes (R2 = 0.75, R2 = 0.69), respectively. The combined assessment of yield, quality, soil organic carbon and soil sustainability shows that rotations based on legume crops performed better and provided a model of sustainable crop intensification. Thus, adding legume to the cropping system and implementing integrated nutrient management (INM) could gradually improve soil quality in agro-ecologies where fennel predominates.

Background: Mungbean and Urdbean are the important pulses in India which are regarded as prospective protein source for human daily diet and rich source of protein and carbohydrate. Mungbean Yellow Mosaic Virus is one of the destructive diseases to pulses and transmitted by whitefly. Among the pulses, mungbean and urdbean are severely affected by MYMV in India. Present investigation was aimed to determine the congenial and mitigating factors of mungbean and urdbean crops with reference to infection of MYMV and its vector. Methods: The morphological and biochemical analysis was carried out by factorial RCBD consisting of two factors viz., factor 1: Crops (V) (Mung bean and Urd bean) and factor 2: observation at 15 days interval up to 90 DAS (S) for recording different morphological and biochemical parameters. Result: Morphological parameters of urdbean are able to mitigate the vector incidence and indirectly reduced the MYMV infection in urdbean than mungbean. Further, the biochemical parameters levels were more in urdbean than mungbean and their levels increased with the increased MYMV incidence. Hence, it is concluded that the morphological characters are found responsible for vector infestation where as biochemical levels are important for the infection of MYMV in both the crops.
背景:绿豆和乌豆是印度重要的豆类，被视为人类日常饮食中潜在的蛋白质来源和丰富的蛋白质和碳水化合物来源。绿豆黄花叶病毒是一种通过粉虱传播的对豆类具有破坏性的病害。在豆类中，绿豆和黑豆在印度受到MYMV的严重影响。本研究旨在结合MYMV及其病媒的侵染情况，确定绿豆和豇豆作物的适宜和缓解因素。方法:采用因子RCBD进行形态学和生化分析，因子1:作物(V)(绿豆和乌豆);因子2:每隔15 d观察90 DAS (S)，记录不同的形态学和生化参数。结果:与绿豆相比，蚕豆的形态参数能够减轻病媒的发病率，间接降低MYMV在蚕豆中的感染。此外，赤豆的生化指标水平高于绿豆，且随着MYMV发病率的增加而升高。因此，我们得出结论，形态特征是媒介侵染的原因，而生化水平对两种作物的MYMV侵染都很重要。

Background: Stem and pod rot is an economically important soil borne disease of groundnut caused by Sclerotium rolfsii Sacc. resulting in significant yield losses across the globe. Bacillus spp. is rod-shaped and gram-positive bacterium which is predominantly found in the soil. Hence, considering the importance of the disease, the present investigation was carried out to evaluate the indigenous Bacillus spp. for plant growth promotion and to inhibit the pathogen in groundnut. Methods: Totally nineteen Bacillus spp. isolates from healthy groundnut rhizosphere and their antagonistic potential was recorded. The molecular characterization of five efficient Bacillus spp. was carried out using 16S rDNA. Later, morphological and biochemical characterization and plant growth promoting traits were recorded. Result: All nineteen isolates of Bacillus spp. showed antagonistic potential against S. rolfsii. Five Bacillus spp. isolates which showed higher inhibition of the pathogen were identified as B. subtilis, B. pacific, B. cereus, two isolates belonging to B. tropicus through molecular technique. The morphological, biochemical characters and growth promoting traits were recorded.

Background: The effectiveness of soybean inoculants in field conditions may be improved through the joint application of rhizobia and plant growth-promoting bacteria (PGPB). Plant nutrients may also contribute to the higher efficacy of microbial inoculants as well as the growth and development of plants. Methods: A field experiment was performed to evaluate the responses of the rhizomicrobiome and soybean to seed treatments with multiple bacterial strains (Bradyrhizobium japonicum, Bacillus subtilis, Bacillus megaterium and Azotobacter chroococcum), applied individually or in consortia, with and without nutrient complex (S, Mg, Mn, Fe, Zn, Cu, B and Mo). Result: Seed treatments with microbial consortia of Br. japonicum, B. subtilis/B. megaterium, A. chroococcum strains and nutrients had the highest effect on the abundance of total bacteria, nitrogen-fixing bacteria, actinomycetes and activity of dehidrogenase in the soybean rhizosphere. The highest effect on plant height, plant weight, pod number, pod weight, seed number and seed weight was obtained from treatment with Br. japonicum strains with nutrients, followed by co-inoculation with B. megaterium and A. chroococcum. In comparison with the control and Bradyrhizobium single inoculation, a statistically significant increase in the seed yield was recorded in treatment with Br. japonicum, B. megaterium, A. chroococcum and nutrients, reflecting the highest increase in protein and oil yield. The interactive effects of microbial consortia and nutrients could be used as promising seed technology for sustainable soybean cropping.

Background: Drought is the foremost environmental restraint that effects the growth and yield of chickpea. The mechanism of response to drought differs with genotype and growth stages of individual crop species. The activation of antioxidant enzymes is an alternate defensive system against oxidative stress that ultimately decide development of putative drought tolerant mechanism. Methods: Eighty-three chickpea genotypes were grown under normal and drought stress conditions and leaf samples were used to estimate different biochemical parameters including total sugar, lipid peroxidation (MDA), chlorophyll, proline and protein along with estimation of activities of different antioxidant enzymes viz., catalase (CAT) (EC 1.11.1.6), ascorbate peroxidase (APX) (EC 1.11.1.11), superoxide dismutase (SOD) and peroxidase (POX). Result: Positively significant correlation was found among proline under control with proline underwent stress (r=0.441), MDA under stress with proline under control (r=0.365) and MDA under control (r=0.336) at 1% level of significance. Positively significant correlation was also investigated between SOD under stressed condition with SOD under control (r=0.665), POX (0.449) and APX under stress (0.423), CAT under control (0.471) and CAT under stress condition (0.374) at 1% probability level. Heatmaps along with dendrograms represented expression levels of different antioxidant enzymes activities that showed variations among different genotypes. In conclusion. total sugar, proline and Malondialdehyde, have been increased under drought stressed condition whilst total chlorophyll and protein were decreased. While antioxidant enzymes viz., POX, APX, CAT and SOD levels increased under drought stressed conditions.
