Yield gap analysis of front line demonstrations on green gram in Dausa district of Rajasthan, India

The present study was conducted at the farmers' fields' of Dausa district of Rajasthan during Kharif 2012 and Kharif 2013. A total of 20 demonstrations of green gram variety RMG 492 in 10 ha area having similar number of traditional practices or local check was carried out in sandy loam soil under rainfed conditions. Yield of front line demonstrations trials and potential yield of the variety were compared to estimate the yield gap which were further categorized into technology gap and extension gap. The technology gap was recorded higher during Kharif 2013 (277 kg/ha) than Kharif 2012 (225 kg/ha). The extension gap was higher during Kharif 2012 (65 kg/ha) than Kharif 2013 (61 kg/ha). The average technology gap was 251 kg/ha and the average extension gap was 63 kg/ha. The technology index was higher during Kharif 2013 (52.96%) than Kharif 2012 (39.13%). Average technology index was recorded 46.05%. The yield of green gram demonstrations were recorded by the tune of 6.5, 4.75 and 5.49 q/ha as the highest, lowest and average yield, respectively. Whereas average yield of local check was 4.86 q/ha, representing 12.97% yield increase in demonstrations over local check. The average gross returns (Rs 27450) which was 12.98 per cent higher over control. The average net returns (Rs 12219) was 16.82 per cent higher over local check. The average B:C Ratio of the demonstrations were recorded 1.80 where as it was 1.73 in local check.
