From the experiment it was observed that treatment T₇ [RDF(75%)+ (25%) neem oil cake] has significant effect on disease incidence and pest population by reducing incidence of YVMV from 32.42% to 19.56%, jassid population from 11.57 to 6.53 per three leaves,mite population from 11.98 to 8.11 per three leaves, white fly population from 13.61 to 6.64 per three leaves and fruit borer from 17.94 % to 7.94 %. Maximum number of fruits per plant 15.02 was recorded in T₇. Fruit yield per hectare varied significantly and was maximum with T₇ (10.49 ton) and was minimum with T₁₁ (7.30 ton). T₇ (10.49 ton) and T₅ (9.85 ton) and T₁₀ (9.65 ton) were at par with each other. Combined use of 75 % RDF as inorganic fertilizer with 25 % RDF through neem oil cake (T₇) recorded highest gross income of Rs.1,45,770/-, net income Rs.85,458 /- per hectare and maximum benefit cost ratio 2.42.
