Impact of Frontline Demonstrations on Yield and Economics of Pigeon Pea inBengaluru Rural District of Karnataka

摘要

Pigeon pea (Cajanus cajan L.) is an important pulse crop grown during kharif. Low productivity of pigeon pea is due to inappropriate production practices and diminishing soil fertility. The other reason for low productivity in pigeonpea is continuousadoption of maize based cropping system in Bengaluru Rural district. To overcome this problem, Krishi Vigyan Kendra, Bengaluru Rural district conducted 131 frontline demonstrations using improved management practices in pigeon pea from 2009-10 to 2016-17in cluster villages of Bengaluru Rural district. There was an appreciable increase in yield level, i.e., 77.5 per cent in pigeon pea under demonstration plots. The highest seed yield of 1625 kg ha-1 was recorded in 2010-11, which was 22.64 per cent moreover the farmer's practice (1325 kg ha~(-1))- The highest extension gap 300 kg ha-1 was recorded during 2010-11. The lower values of technology gap (175 kg ha~(-1)) and technology index (9.72 %) were recorded during 2010-11. The improved technology gavehigher gross returns, net returns with higher benefit cost ratio as compared to farmer's practices.
