International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad organic carbon 0.49% available N 197.40 kg/ha, available P2O5 10.62 kg/ha and available K2O 335, 20 kg/ha. The nine integrated nutrient management treatments were laid out in a randomized complete block design keeping three replications. Results The data indicate that the application of 50% RDN through fertilizer + 50% RDN through compost + Rhizobium ciceri as in T9 recorded significantly higher seed yield (11.06 q/ha) straw yield 15.48 q/ha) and harvest index 41.29%). The combined use of organic and inorganic fertilizers along with bioferilizers has been reported not only to meet the nutrients need of the crop but also has been found to sustain large – scale productivity goals. These results are in accordance with the findings of Meena and Baldev, 2013. Amongst the integrated nutrient management treatments, T9 having (50% RDN through fertilizer + 50% RDN through compost + Rhizobium ciceri) gave the maximum net income upto Rs. 29900/ha with 2.02 B:C ratio which was followed by T2 (100% NPK through fertilizer), The net income was Rs. 20020/ha under under 100% RDN by organic source. However, the lowest net income fetched in T1 which was Rs. 7851/ha. The net income under these integrated nutrient management treatments was exactly in accordance with the increased grain yield and higher market values. References Gour, P.M., Tripathi, S., Gowda, C.

Singh, SudhirKumar Rajpoot and Rajnish Pandey Banaras Hindu university Varanasi (UP)-221 005 India The importance and potential of rapeseed-mustard crop is well known as it is the key oilseed crop that can help in addressing the challenge of demand - supply gap of edible oil in India. India is the third largest producer of rapeseed-mustard after Canada, China and contributing to around 11 % of world’s total production. Rapeseed-mustard are the second largest oilseed crops in India. In India, during 2019-20, it was grown on 6.86 million hectares with an annual production of 9.12 million tonnes yielding 1331 kgha -1 . Rapeseed and mustard productivity in India has risen considerably in the last eight years, from 1840 kg ha -1 in 2010-11 to 1980 kg ha -1 in 2018-19, with production jumping from 61.64 m t in 2010-11 to 72.42 m t in 2018-19. For the crop year 2019-20, India's average output was 1.4 t ha -1 . Inappropriate application of chemical fertilisers degrades soil characteristics and reduces crop output.These compounds have extremely dangerous side effects, including changes in soil structure and texture, unbalanced nutrient supply to plants, pollution of land and water bodies, and decreased soil microbial activity.Integrated nutrient management is a method of improving soil fertility and plant nutrient availability by combining the best inorganic and organic fertilisers with biofertilizers to ensure 510 | Page Sustainable soil management for resilient rainfed agro-ecosystem: conservation agriculture, organic farming, INM, soilmicroorganisms-plant interactions
