International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad intercropping systems contributes to in achieving food and nutritional security, income growth, employment generation and sustainable rainfed agriculture. Double cropping system aims to make optimum use of land through permitting the production of an extra crop cultivated in winter/rabi after kharif season. In general, the double cropping becomes feasible when there is on time onset of monsoon rains that helps to successfully establish the first crop, then persist for an extended period of time to allow the planting and maturation of the second crop .To develop feasible and sustainable double cropping systems, production factors such as length of growing season, cropping sequence, crop compatibility, biological complementarity, and planting time must be considered (Ravindra Chary et.al. 2020; 2022). Agroclimate zone-wise, rainfed cereals, pulses, oilseeds and cotton-based production systems wise intercropping systems, double cropping systems are suggested. d. Building resilience at agricultural land scape level: Scientific land use planning in drought prone regions is one of the rational approaches for drought mitigation. Ravindra Chary et al. (2005) suggested that the delineation of Soil Conservation Units (SQUs), Soil Quality Units (SQUs) and Land Management Units (LMUs) from the detailed soil survey maps at cadastral level in a microwatershed would help in land resource management. SCUs and SQUs are merged in GIS environment to delineate land parcels in to homogenous Land Management Units with farm boundaries. LMUs would be operational zed at farm level for taking decisions on arable, non-arable and common lands for cropping, agroforstry, agrohorticulture, etc., and further, for leaving the most fragile land parcels for ecorestoration. Rainfed land use planning modules should be based on these units for risk minimization, enhanced land productivity and income, finally for drought proofing. Conclusion Crop diversification action plans need to be developed and implemented in convergence with various national/state programmes. a. Crop diversification with alternate crops aligning with agroecology specificity including fodder and vegetable crops beyond normal sowing windows of the rainfed crops b. Scaling out Real-time contingency plans as two-pronged approach i.e. preparedness and real-time response References Ravindra Chary, G., Vittal, K.P.R., Ramakrishna, Y.S., Sankar, G.R.M., Arunachalam, M., Srijaya, T. and Bhanu, U. 2005.

Climate resilient agriculture for risk mitigation T2a-33P-1508 Demonstration of Climate Resilient Technologies for Mitigation in the North East M. Thoithoi Devi, Bagish Kumar, Olivina Katharpi and Rajesh Kumar ICAR-Agricultural Technology Application Research Institute, Zone-VI, Guwahati, Assam, India Climate change is not the corner stone of the natural aberration. It is very much obvious through abnormal weather conditions. This man-made calamity has negatively impacted every dimension of living. Agriculture of the entire country is not the exception from this and as far as north east region is concerned, due to its geographical position, it has affected it more. Considering the high vulnerability of the region, the ICAR has introduced the different climate resilient interventions in farmers’ field under Technology Demonstration Component (TDC) of NICRA in the state of Assam, Arunachal Pradesh & Sikkim. During 2018-19, in KVK Dhubri, Assam, an intervention on in-situ soil moisture conservation using straw mulch in Colocasia was introduced in farmers’ field. The main objective behind this intervention was to minimize the evaporation loss of water from soil and to supress weed growth. It was found that yield of local check was 43.51 q/ha whereas that of demonstration was 52.25 q/ha resulting in 20.09% increase in yield over local check. The other intervention undertaken by the same KVK was production of low cost vermicompost unit and reason behind the intervention was recycling of farm and household waste to convert them to nutrient rich vermicompost. From an unit of 6×3×2.5 cubic ft, net return of Rs. 4500.00 was obtained with B.C ratio of 2.5. In KVK Sonitpur, Assam, during 2018-19, paddy straw mulching in ginger variety Nadia was introduced in farmers’ field. During rabi season, rainfall was very less and low soil moisture affected the growth and development of winter crops. So this intervention was undertaken to conserve soil moisture as well as to suppress weed growth. Yield of local check and demonstration were 22 q/ha and 43 q/ha respectively. Increase in yield over local 311 | Page
