On Farm Testing (OFT) of palak were conducted in Ernakulam Krishi Vigyan Kendra during 2012-13. Highest green leaf vegetable yield (18.00.q/ha) was recorded in variety Harit Shobha and All Green in first year with farmers practice. Programme was continued in 2 nd year under Front Line Demonstration (FLD). It was observed that Harit Shobha cultivar gave 20.0 q/ha -1 green leaf yields which was higher over All Green and farmers practice. An average yield of two cultivar Harit Shobha and All green was 15.5 q/ ha -1 and 17.7 q ha -1 in OFT and FLD, respectively. The average technology gap, extension gap and technology index of 2.9 q ha -1 , 9.5 q ha -1 and 38 per cent and 1.8q ha -1 , 7.5qha -1 and 30 per cent during first and second year, respectively. Technology index reduced from 38 to 30 per cent during the study period means technology was accepted by the farmers. As a result, 500 farmers initiated the small scale farming of palak in the district with the technical guidance provided from KVK.
On Farm Testing (OFT) of Yard long bean variety Arka Mangla and Lola were conducted at KVK Ernakulum during 2014-15 with five farmers in area of one ha. The OFT were conducted with active participation of farmer's to disseminate improved technology of Yard long bean to achieve production potential. The improved technologies consisting the use of modern variety, seed treatment, balance fertilizer application and integrated pest management. On Farm Testing data were recorded with respect to green pods yield as compared to farmer's local practice. The results of suggested that improved technology recorded higher green pods yield 50.7 q/ha, 45.6 q/ha and 40.7 q/ha, in Arka Magala and Lola and Local variety, respectively. In addition to high in yield of Arka Mangla, lower values of technology gap, extension gap and index existed. The improved technology gave higher gross return, net return with higher benefit cost ratio Yard long bean as compare to farmer's practices.
