Khagribari village under Palamu-2 Block selected purposively (KVK Adopted Village) for implementation of the NICRA project. Several activities were done during 2010- 11 to 2020-21. Majority of the farmers of Khagrabari village were marginal farmer. Flood, irrigation, water conservation, diseases infestation on plant and occupational migration were the major problem of the village. Some innovative and progressive farmers were developed and exposed their activity through different programme. In our study we discuss about the few successes point of NICRA project in Palamu District. The objective of the study was to show the impact of NICRA project in Palamu District through analysis of different success point. Palamu is situated between 23 0 50’ and 24 0 80’N to 83 0 55’ to 85 0 30’E latitude and at an altitude of 222.00 m above from mean sea level. However, the normal rainfall in Plamau is 1257.8 mm. Total geographical area of the district is 524690 ha (5043. 85 km 2 ). Out of which nearly 1,73,553 hectares comes under net cultivable land, 1,67,848 hectares is covered by forest and 24,750 hectares comes under barren and non-cultivated land. Murma Dulsulma village under Satbarwa Block was selected purposively for implementation of NICRA project. Village was selected on the basis of climate vulnerability. Technology and impacts Solid waste management through composting: Organic matter always plays pivotal role in minimizing the effect of global warming by way of reducing fluctuation in diurnal temperature 887 | Page Institutional and policy innovations for accelerated and enhanced impacts

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad variation and also minimizing the maximum soil temperature. Further organic matter reduces the irrigation water requirement and thus reduces environmental pollution also. Considering this Palamu KVK took initiative to popularize the use of organic manure by promoting the technology of compost preparation Palamu Krishi Vigyan Kendra initiated demonstration programme for proper utilization of cow dung, rural farm waste, kitchen wastes, other locally available organic waste materials and organic residues through preparation of compost by NADEP method to cut down the shortage of availability of organic manures. Demonstration was also organized on low-cost preparation of compost by heap method. Awareness was also developed to improve the quality of cow dung manure with minimum interference. Impact: Laboratory analysis of samples collected indicated that quality of organic manures produced through NADEP or heap method was much better than that used by farmers of the village. It is also too noteworthy that use of organic manure has increased 143 ton from the Bench marks (when compared with status of organic manure use before inception of the project at the village). Bohita village was promoted organic manure production through composting under MGNREGA with technical support from Palamu Krishi Vigyan Kendra. Use of black polythene mulch in winter cucumber: Cucumber is profitable crop. This crop is primarily grown in the summer months. But farmers of this village prefer to grow this crop during rabi season as price of this crop remain high during winter months. Problem arises when winter temperature comes below 12 °C which not only affect physiological growth but also hampers fruit set and development of cucumber. Black polythene mulch was used to increase soil temperature thereby getting rid of the problems associated with low temperature. Comparative performance of technology: This technology performed well under stressful environment during winter and it out-yielded the traditional practice of growing cucumber without mulch. On an average, soil temperature under mulch was 1-1.5°C higher during day and 4.5-5 °C during night as compared to crop without mulch which increased fruiting period by 21 days, decreasing flower drop by 12% and advancement of fruiting 5 days under mulch. Black polythene mulching in cucumber resulted in an yield increase of 8.19% compared to local practice. The net returns and B:C ratio were Rs.108200 ha -1 and 2.6 in treatment compared to Rs.97700 ha -1 and 2.51 under local practice. Renovation of existing pond for harvesting, storing and recycling of rain water A large area of the NICRA adopted village remains uncultivated during rabi seasons as only 10% of total cultivated area were irrigated using well by lifting ground water as well as canal water. Though there exist a number of small and large size ponds but most of them were seasonal and cannot be used as source of irrigation during critical stages of rabi crops. The NICRA village (Murma Dulsulma) of Palamu district experiences annual rainfall of about 1257.8 mm received mostly during the period from July- September but most of the water Institutional and policy innovations for accelerated and enhanced impacts 888 | Page
