International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Economics of different treatments was worked out based on pooled results of pod and haulm yield of groundnut in terms of net returns ha -1 and B:C ratio considering the prevailing market price of produce and cost of cultivation. Results Based on three years pooled mean pod and haulm yield of groundnut and soil moisture content was affected significantly due to the application of hydrogel and organic manures. Significantly highest pod and haulm yield and soil moisture content was recorded under application of hydrogel @ 2.5 kg ha -1 over control. Among organic manures, application of FYM @ 10 t ha -1 was recorded significantly highest pod and haulm yield as well as soil moisture content as compared to control, but it was remained at par with vermicompost @ 2.0 t ha -1 in respect of pod yield and soil moisture content. Maximum rain water use efficiency (4.28 kg ha -1 mm -1 ) was obtained with application of hydrogel@ 2.5 kg ha -1 and FYM @ 10 t ha -1 as compared to rest of treatments under different levels of hydrogel and organic manure, respectively. Similarly, the application of hydrogel @ 2.5 kg ha -1 and FYM @ 10 t ha -1 gave the highest net returns of Rs. 82363 ha -1 and 80600 ha -1 with B: C ratio of 2.50 and 2.42, as compared to the rest of treatments under different levels of hydrogel and organic manure, respectively.

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad From the above findings, it could be concluded that application of hydrogel @ 2.5 kg ha -1 and FYM @ 10 t ha -1 was found superior in increasing the productivity, rain water use efficiency and economics of groundnut under rainfed conditions of Saurashtra region. T1-13P-1023 Straw Mulching as Climate Resilience Measure for In-situ Water Management and Enhancing Productivity of Rainfed Soybean S.H. Narale*, M.S. Pendke, W.N. Narkhede, B.V.Asewar and P.H. Gourkhede Vasantrao Naik Marathwada Agricultural University, Parbhani (M.S.) *sskhune2602@gmail.com Soybean is a major kharif crop grown in Marathwada region of Maharashtra under rainfed condition and is being apreferred crop by the marginal and small rainfed farmers. The region receives mean annual rainfall of 880 mm. Rainfall in uncertain and erratic in this region. The productivity of soybean particularly in Marathwada region is variable due occurrence of 3 to 4 dryspells during July to September. The crop productivity decreases with either deficiency of rainfall or its distribution or due to moisture stress in critical growth period. Mulching is one of the important practices to conserve rainwater and thereby soil moisture which help sustain the crop productivity. It was also noted that straw mulching increased soil moisture content in the maize-wheat cropping system in the north-western regions of India, and thus enhanced crop productivity (Sharma et al. 2010).The study evaluated the effect of straw mulching on productivity and profitability of soybean with in-situ moisture conservation on farmer’s field. Methodology Research demonstrations were conducted on farmers’ fields during 2016-17 to 2020-21 under FLD at village Babhulgoan in Parbhani District in Marathwada region of Maharashtra. Most of the farmers were cultivating soybean under rainfed condition and were advocated to apply straw mulch in inter-row of soybean crop for moisture conservation. Demonstration fields were selected based on the willingness of the farmers. The rainfall data was collected from the nearest rain gauge station. The duration of dryspells and number of dryspells were recorded every year. The data on crop yield in both the field i.e. with straw mulch and without straw mulch were recorded. Results The mean annual rainfall of the station is 880.9 mm. Out of the 5years, above normal rainfall occurred during 4 years and below normal rainfall was observed in one year. However, the distribution of rainfall was different in every year. Out of the 5 years, 3 years i.e. 2017, 2019 and 2020, 4 dryspells were observed every year which has resulted moisture stress during crop period. 46 | Page Resilience through land and water management interventions, water management and governance

Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad<br />

Economics <strong>of</strong> different treatments was worked out based on pooled results <strong>of</strong> pod and haulm<br />

yield <strong>of</strong> groundnut in terms <strong>of</strong> net returns ha -1 and B:C ratio considering the prevailing market<br />

price <strong>of</strong> produce and cost <strong>of</strong> cultivation.<br />

Results<br />

Based on three years pooled mean pod and haulm yield <strong>of</strong> groundnut and soil moisture content<br />

was affected significantly due to the application <strong>of</strong> hydrogel and organic manures.<br />

Significantly highest pod and haulm yield and soil moisture content was recorded under<br />

application <strong>of</strong> hydrogel @ 2.5 kg ha -1 over control. Among organic manures, application <strong>of</strong><br />

FYM @ 10 t ha -1 was recorded significantly highest pod and haulm yield as well as soil<br />

moisture content as compared to control, but it was remained at par with vermicompost @ 2.0<br />

t ha -1 in respect <strong>of</strong> pod yield and soil moisture content. Maximum rain water use efficiency<br />

(4.28 kg ha -1 mm -1 ) was obtained with application <strong>of</strong> hydrogel@ 2.5 kg ha -1 and FYM @ 10 t<br />

ha -1 as compared to rest <strong>of</strong> treatments under different levels <strong>of</strong> hydrogel and organic manure,<br />

respectively. Similarly, the application <strong>of</strong> hydrogel @ 2.5 kg ha -1 and FYM @ 10 t ha -1 gave<br />

the highest net returns <strong>of</strong> Rs. 82363 ha -1 and 80600 ha -1 with B: C ratio <strong>of</strong> 2.50 and 2.42, as<br />

compared to the rest <strong>of</strong> treatments under different levels <strong>of</strong> hydrogel and organic manure,<br />

respectively.<br />
