Field trial was conducted at the instructional farm of Krishi Vigyan Kendra Jajpur, Odisha during summer 2015 and 2016 to study the impact of Organic, Inorganic Fertilizer and integrated Nutrient Management on disease pest incidence, yield and economics Okra variety-Pusa A-4. From the two years trials 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 31.68% to 18.79%, jassid population from 9.65 to 4.62 per three leaves, mite population from 9.45 to 5.68 per three leaves, white fly population from 11.24 to 4.53 per three leaves and fruit borer from 16.29% to 6.16%. Fruit yield per hectare varied significantly and was maximum with T₇ (9.99 ton) and was minimum with T₁₁ (6.96 ton). T₇ (9.99 ton), T₅ (9.44 ton) and T₁₀ (9.29 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.1,39,785/-, net income Rs. 80,302 /- per hectare and maximum benefit cost ratio 2.35.
