The present study was conducted in the Chamble division of Madhya Pradesh during the year 2016-17 to 2019-20 by Krishi Vigyan Kendra, Morena (M.P). conducted 190 Cluster frontline demonstrations on Chickpea in 76 ha area under real farming situations in the farmer’s fields of six adopted villages of district Morena (M.P.). The objective was to transfer the technology to increase the productivity of chickpea through various types of interventions viz., Varietal, Seed treatment, Plant Protection, Rhizobium, Irrigation, STV based nutrient management and IPM. High yielding variety of Chickpea RVG 202 was given to the farmers and basal application of 20 kg N + 60 kg P2O5+20 kg K2O /ha in the form of DAP, MOP and Zinc sulfate @ 25 kg /ha as per demonstration were advised. The seed was treated before sowing. It was observed that in cluster front line demonstrations, the improved chickpea variety RVG 202 recorded an average yield of 1850, 1880, 2046 and 2123 kg/ha were much higher than as compared to the average yield of farmers practices 1440, 1660, 1630 and 1625 kg/ha respectively during 2016-17, 2017-18, 2018- 19 and 2019-20. The average per centage increased in the yield over farmer’s practices was 28.40, 13.3, 25.5 and 25 for the year 2016-17, 2017-18, 2018-19 and 2019-20 respectively. The technology gap was found 109 Kg to 590 Kg over the potential yield. The highest extension gap of 498 kg/ha was recorded in 2019-20 and the lowest was observed 220 kg/ha in 2017-18. From these results, it is evident that the performance of improved variety was found better than the local check under the same environmental conditions. Farmers were motivated by the results of agro technologies applied in the CFLDs trials and it is expected that they would adopt these technologies in the coming years.
