International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Moisture Conservation Techniques in Maize under Rainfed Agro-Eco System of Jammu Region is proposed. Methodology A field experiment was conducted at the Research Farm of Advanced Centre for Rainfed Agriculture, ACRA Dhiansar of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu during the Kharif season of 2016. The soil of the experimental field was sandy loam in texture, near to neutral, low in organic carbon and available nitrogen and medium in available phosphorous and potassium. The experiment was laid out in randomized block design during kharif season with three replications each. The experiment consisted of 9 treatments viz. T1- Flat Bed, T2- Broad Bed Furrow, T3- Flat Bed + mulching with in-situ raised Dhaincha, T4-Broad Bed Furrow +mulching with in-situ raised Dhaincha, T5-Flat Bed +mulching with in situ raised Sunhemp, T6- Broad Bed Furrow +mulching with in-situ raised Sunhemp, T7- Flat Bed +mulching with Leuceana prunings, T8- Broad Bed Furrow +mulching with Leucaena prunings and T9- Farmer’s practice. The field was ploughed twice with disc harrow followed by planking to prepare a fine seed bed. Plot paths, replication borders and drainage channels were made manually. The plots were levelled before planting of kharif maize. However, Broad Bed and Furrow plots were raised using Bed making machine. Hybrid maize variety Double dekalb was sown in line during July using full dose of P and K along with 2/3 rd dose of N as basal dose at the time of sowing through inorganic sources of nutrients viz. Urea, DAP and MOP, respectively as per package of practices and remaining Nitrogen was applied just before the application of mulches while in farmers practice only Urea and DAP as inorganic fertilizers were applied in maize sown by broadcasting method without following any plant protection measures . However, the seeds of the mulch crops viz: Dhaincha and Sunhemp were also sown by broadcasting method at the time of final ploughing as per the technical programme. Leucaena pruning’s (Ex-situ) were taken from the plants growing in surroundings 35 DAS at the time of spreading of mulches. Results The experimental results revealed that all the moisture conservation techniques showed significant results over the other treatments. However, the treatment (T4) Broad Bed Furrow + mulching with in-situ raised Dhaincha recorded significantly higher values of Growth and yield and yield attributing characters and was found to be statistically at par with the treatment (T8) Broad Bed Furrow (BBF) + Mulching with Leucaena leaves and Treatment (T6) Broad Bed Furrow +mulching with in-situ raised Sunhemp. However, the treatment (T4) Broad Bed Furrow + mulching with in-situ raised dhaincha recorded significantly higher grain yield (3281 kg ha -1 ) 643 | Page Resource conservation and rainfed agriculture

Conclusion<br />
On the basis <strong>of</strong> experimental findings, it may be concluded that among the different in-situ soil<br />
moisture conservation techniques in maize, Broad Bed Furrow (BBF) + mulching with in-situ<br />
raised Dhaincha, provided significantly highest grain yield with maximum net returns, B:C ratio<br />
and Rain Water Use Efficiency under rainfed situations which not only helped in conserving the<br />
moisture in the soil pr<strong>of</strong>ile but also enhanced the productivity <strong>of</strong> maize especially during<br />
mid/terminal dry spell situations which can contribute to food security <strong>of</strong> kandi belt farmer’s<br />
under the Shiwalik Foothils <strong>of</strong> Jammu and Kashmir.<br />
