International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Methodology The present investigation was performed at Agriculture research farm, Institute of Agricultural Sciences (IAS), BHU, Varanasi during Rabi 2017-2018 to evaluate the effect of integrated nutrient management on wheat yield attributes in eastern Uttar Pradesh. The experiment was laid out in randomized block design having eight treatments i.e. Control (No fertilizer), 100% RDF NPK, 100% RDF NPK+ Zn +Fe, 75% RDF NPK+ Carpet waste compost+ Zn+Fe, 75%RDF NPK+Wheat straw compost+ Zn+Fe, 75% RDF NPK+Bagasse compost+ Zn+Fe ,75% RDF NPK+Paddy straw compost + Zn+Fe, 75% RDF NPK+Pressmud compost+ Zn+Fe and was replicated thrice. Results Results indicated that among all the treatment combinations highest spike length, number of grains per spike and test weight was recorded in the treatment combination of 75% RDF NPK+ Pressmud+ Zn+Fe. The minimum spike length, number of grains per spike and test weight was observed in control treatment. And among all the treatment combinations highest grain yield and straw yield was recorded in the treatment combination of 75% RDF NPK+ Pressmud+ Zn+Fe. The minimum yield was observed in control treatment.highest harvest index was also recorded for the treatment combination of 75% RDF NPK+ Pressmud+ Zn+Fe. However, the application of 75% RDF NPK+ Paddy straw compost+Zn+Fe and 75% RDF NPK+ Bagases+Zn+Fegross return were found at par to each other. Amongst the treatment, the highest gross return was recorded in the treatment combination of 75% RDF NPK+ Pressmud+ Zn+Fe (72860₹ha -1 ), which was significantly higher than the other treatment combinations. The minimum gross return (35833 ₹ha -1 ) was observed in control. 6000 Yield of wheat 5000 4000 3000 2000 1000 0 Grain yield kg per ha Straw yiled kg ha harvest index (%) Impact of integrated nutrients management on yield of wheat Sustainable soil management for resilient rainfed agro-ecosystem: conservation agriculture, organic farming, INM, soil-microorganisms-plant interactions 507 | Page

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Conclusion The present findings of the study indicated the application of 75% RDF+ pressmud+Zn+Fegreatly influenced the yield along with improvementof the the yield attributes, yieldand quality of wheat in eastern UP.

Tiwari, Sudhanshu Pandey, Abhishek Soni, Satish Singh Baghel and Sonali Pandey All India coordinected Research Project on Dryland Agriculture JNKVV College of Agriculture, Rewa 486001 (M.P.) * sheshmanikurmvanshi@gmail.com Chickpea (Cicer arietinum L.) is world’s third most important winter season pulse crop after beans and field pea. It is grown in tropical, subtropical and temperate regions of the world. It contains high 20-22 % protein, rich in fibre, carbohydrates, vitamins and minerals (Guar et al. 2010) The production of pulse crops in our county including chickpea is not enough to meet the domestic demand of the population. There is vast scope to enhance the productivity of chickpea by improved Aagronomic practices and balanced nutrient management with bio fertilizers. Fertilizers are becoming costlier and it is becoming difficult for the poor farmers with poor economic means to apply recommended doses of fertilizers. It is now well realized that to protect the soil health, judicious use of fertilizers and combination of organic and inorganic sources of nutrients is beneficial. Pulses are mainly grown in marginal lands and poor productivity of the crops is mainly due to inadequate nutrient supply. Methodology The field experiment was conducted during winterseason of 2020-21 under AICRP for Dryland Agriculture, JNKVV Kuthulia farm, College of Agriculture, Rewa (M.P.) The soil of the experimental field was silty clay- loam having pH 6.78, electrical conductivity 0.41 DS/ m, 508 | Page Sustainable soil management for resilient rainfed agro-ecosystem: conservation agriculture, organic farming, INM, soilmicroorganisms-plant interactions
