Impact of frontline demonstrations (FLDs) on the yield of green gram, Vigna radiata Lin tribal belt of East Godavari district of Andhra Pradesh

The study was carried out during Rabi in five villages of East Godavari district of Andhra Pradesh during 2014–15. All 40 demonstrations on green gram crop were carried out on an area of 8 ha by the active participation of farmers with the objective to demonstrate the improved technologies of green gram production potential. The improved technologies consisted of use of modern variety, seed treatment with Rhizobium culture, balanced fertilizer application and integrated pest management. Frontline demonstrations (FLDs) recorded higher yield as compared to farmers’ local practice. The improved technology recorded higher yield of 947 kg/ha compared to 732 kg/ha in farmers’ local practice. In spite of increase in yield, technological gap, extension gap and technology index existed. The improved technology gave higher gross return, net return with higher benefit/cost ratio than farmers’ practices.
