In order to examine the technological gap in tomato production and gauge the efficacy of INM technology, Krishi Vigyan Kendra, in the Saharsa district of Bihar, performed farmer-participatory trials at farmers' fields in two villages. The study's results showed that treatment T3 [(RDF 200:100:80 N:P:K) + FYM (200 q/ha) + Lime + Boric acid (1%) + Zinc Sulphate (1%)] performed best in terms of the number of primary branches per plant (6.89), the number of flowers per plant (53.23), the minimum number of days to flowering (41.87), the number of days to 50% flowering (44.36), the number of days to first flowering (49.63). There were 8.86 pickings, 25.22 fruit per plant, a maximum weight of 50.57g for a fruit, 1.46 kg of yield per plant, and 381.56q of fruit per ha. A partial budget study showed that the net returns from T3 were higher than the farmers' practice (Rs. 141298/ha), at Rs. 256904/ha. B:C ratios of up to 2.96 in T3 and 1.90 in farmer practices were discovered.
