Abstract:
To establish the production potential of Blackgram crops, Cluster Front Line Demonstrations (CFLDs) is an appropriate tool. The Participatory Seed Production of Blackgram var. TBG-104 was carried out by the Krishi Vigyan Kensra, Darsi, Prakasam district Andhra Pradesh in rabi seasons at farmer’s field in Prakasam district during 2018-19 to 2020-21. The basic strategy of the project was to promote and extend improved technologies. The improved technologies consisting use of modern variety, seed treatment with Imidacloprid 600 FS @ 5 ml/kg seed, Rhizobium leguminosarum @ 5 ml/kg seed, balanced fertilizer application (NPKS @ 20:40:0:20 kg/ha) and integrated pest management. Impact assessment recorded higher yield as well as higher economic return as compared to the farmer’s local practices. The demonstration of technologies gave higher yield of 17.50 q/ha in an average with 27.27 % increase in average yield over farmer’s local practices. The study also registered improved technology gives higher gross return (Rs. 1,01,125/ha.), net return (Rs. 61358/ha.) with higher benefit cost ratio (2.54:1) as compared to farmer’s local practices (2.05:1).
