India accounts for 33 per cent of the world area and 22 per cent of the world production of pulses. Greengram (Vigna radiate L. Wilczek.) is the third important pulse crop in India after chick pea and red gram. It isgrown in about 36 lakh hectares with the total production of about 17 lakh tonnes with a productivity ofabout 500 kg per hectare. The reasons for low productivity include non adoption of improved varieties andunawareness of recommended crop production and protection technologies. The extent of adoption ofimproved agricultural technologies is a crucial aspect under innovation diffusion process and is mostimportant for enhancing vertical agricultural production. Keeping this in view, frontline demonstrationson green gram were conducted at 20 locations in Chodavaram block of Visakhapatnam district of AndhraPradesh, with an objective to demonstrate the high yielding varieties (HYVs) and latest improvedtechnologies to the farmers. The demonstrations included adoption of HYVs (WGG-42 and IPM-2-14), seedtreatment, integrated nutrient management and timely plant protection in comparison to farmers practice.The incidence of Yellow vein mosaic was 0-5 per cent in improved varieties compared to 20-25 per cent inlocal variety. Both the varieties, WGG-42 and IPM-2-14 recorded 5.3 quintals per ha and 5.8 quintals perhectare, which was much higher than the local variety cultivated by farmer (3.8-4.0 q/ha). The cost economicsalso reflected the superiority of ICM practices which registered BC ratio of 3.53-3.56 when compared tofarmers practice (2.76-3.10).
