International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Continuous application of FYM along with fertilizers showed significant effect on soil available potassium. The range of available potassium content in soil among different treatments was 139 to 192 kg ha -1 . The maximum value (192 kg ha -1 ) of available potassium content in soil was recorded in 50% NPK + 5 t FYM (T10). While the lowest value of soil available potassium (139) content was recorded in 100% NP (T5). Slight increase in the content of soil available potassium was found in the treatments comparing to the initial stage. The treatments where chemical fertilizer was applied along with FYM showed significantly high value of available potassium in soil. The organic manure along with chemical fertilizers resulted in an integrated influence on potassium availability to plant as the organic matter increase accessible adsorption sites for potassium. Conclusion The combined application of FYM along with fertilizers could enhance the soil fertility status in terms of increase in organic carbon, available N, P and K in soil.

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad T4-24P-1130 Response of Mung bean to Higher Doses of Fertilizers under Rainfed Conditions M. D. Giri*, A. N. Paslawar and N. K. Patke Department of Agronomy Dr. Panjabrao Deshmukh Krishi Vidhyapeeth, Akola 444 104 (Maharashtra), India * mdgiri@pdkv.ac.in India is the largest producer of pulses in the world, with a 24% share in global production; it is also a big consumer and exporter of pulses in the world. Being an economical source of protein, high fiber content, vitamins, and minerals, along with the unique ability to restore soil health, pulses have assumed the universal remedy for sustainable production. Pulses are the major source of protein and carbohydrates in the Indian diet. The major pulse crops of India are chickpea (48%), pigeonpea (15%), mungbean (7%), urdbean (7%), lentil (5%), and field pea (5%). Mungbean (Vigna radiata) is an important pulse crop in India and is believed to be originated from India. It is a short-duration legume crop. It is traditionally grown mainly in Asian regions, while its cultivation has spread to other parts of the world recently. India contributes more than 70% of the world’s mungbean production. Mungbean is grown on more than 5.0 million ha in the country, mainly in Rajasthan, Maharashtra, Madhya Pradesh, Karnataka, Orissa, and Bihar, with a total production of 3.09 million tonnes. The average productivity of the mungbean crop is 600kg/ha. Fertilizers can increase food grain production and reduce the risk and uncertainty associated with the production of food crops. Mungbean is an important Kharif season short-duration pulse crop grown on an area of 0.90 lakh ha in the Vidarbha region of Maharashtra state. An increased fertilizer dose was observed beneficial for the mungbean crop in Vidarbha.Therefore, this study aimed to assess the impact of different doses of fertilizers, farm yard manure, and biofertilizers on mungbean in a rainfed environment. The experiment was conducted at Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra), India, between 2018 and 2020. The experiment was laid out in a randomized complete block design with three factors with three replications. There were three fertilizer doses (N1:75% RDF, N2:100%RDF, and N3:125% RDF),twoFYM applications (F1: Control and F2:5 t/ha), and three seed treatments with biofertilizers (B1: Rhizobium, B2: LMn 16, and B3: Rhizobium + LMn 16).Results indicated that 125% RDF application in mungbean crops increased plant height, pods/plant, seed yield/plant, seed yield (kg/ha), and B: C ratio.Furthermore, higher doses of fertilizer increased the number of root nodules per plant and the dry weight of root nodules over other fertilizer doses.Application of the higher doses also 498 | Page Sustainable soil management for resilient rainfed agro-ecosystem: conservation agriculture, organic farming, INM, soilmicroorganisms-plant interactions
