Background: It is a emerging significant legume crop (Green gram) in summer season that plays vital role in the food and nutritional security accomplishment of the country and contributing to protein intake. It is a soil building crop and being a leguminous crop, it fixes atmospheric nitrogen through symbiotic fixation, there by helps in N cycling within the ecosystem. Methods: Cluster frontline demonstrations of greengram were conducted by Krishi Vigyan Kendra, Kolipura Tappar, Harda (Madhya Pradesh) during summer season from 2018-19 to 2022-23. A total 250 front line demonstrations were conducted on green gram in 100 ha area by the active participation of the farmers with the objective of improved technologies of greengram production potentials. Result: The results of the demonstrations observed that on an average yield of greengram under improved technology ranged from 12.12 to 16.38 q/ha with a mean of 14.95 q/ha; which was 23.39 per cent more yield as compared to farmer's practices (12.01 q/ha). Moreover, average yield was also recorded higher under demonstration (16.38 q/ha) over district (16.0 q/ha) and State and country (12.09 and 570 q/ha), respectively. The study exhibited mean extension gap of 293.2 kg/ha, technology gap and technology index assessed more than potential yield of demonstrated variety MH-421. The average mean net return of Rs. 87737/ha with mean B: C ratio of 4.78 was obtained with improved technologies in comparison to farmers' practices (Rs. 65061.6/ha). The present study resulted to convincing the farming community for demonstration of new improved technologies, higher productivity and returns. [ABSTRACT FROM AUTHOR]
