The system productivity was registered maximum in Ridge and Furrow planting system besides generating highest water productivity. Amongst different cropping systems, Maize-mustard cropping sequence has proved its superiority in terms of generating highest Maize equivalent yield, water productivity and net return although Groundnut-wheat has recorded maximum WEY and Gross Return. It has also been observed that Maize-mustard cropping sequence which has observed highest Maize equivalent yield, water productivity and net return has resulted in decline in soil fertility. Conclusion The study recommends practicing ridge and furrow planting especially in Maize and Sorghum crops to promote better drainage and in-situ rain water harvesting in furrows to address intermittent drought.

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad health. Most of the research work on gliricidia as a green leaf manure is focused on nitrogen contribution through gliricidia. However, limited studies have been carried out on contribution of potassium through gliricidia. The integrated long-term effect of gliricidia green leaf manuring as a source of potassium helps in sustaining crop productivity and soil health. The resultant outcome of the study will help to optimize the crop yields as well as balanced fertilization, which may help to reduce the cost on fertilizers and make cotton cultivation sustainable. Methodology An experiment with the combinations of organic and inorganic nutrient sources was conducted during 2015-16 to 2020-21 at the research field of AICRP for Dryland Agriculture, Dr. PDKV, Akola, Maharashtra on rainfed cotton in Vertisols. The soil of the experimental site was moderately alkaline in reaction, low in available nitrogen (185.80 kg ha -1 ), medium in available phosphorus (14.60 kg ha -1 ) and high in available potassium (322.0 kg ha -1 ). Soil samples were collected at harvest of crop and were analyzed as per standard methods. Results The pooled results (2015-16 to 2020-21) indicated that the highest seed cotton yield (1282.73 kg ha -1 ) was recorded with the application of 100% NP + 10 kg K(inorganic)+20 kg K through gliricidia (T 4). Similar results were recorded by Satpute et al. (2019). The data presented in the table indicate that the higher Sustainability yield index (0.36) was recorded with the application of 100% NP + 10kg K(inorganic)+20kg K through gliricidia(T4), indicating the significant role of conjunctive use of gliricidia green leaf manure along with chemical fertilizers in sustaining the cotton productivity.
