The effect of diazotrophs and chemical fertilizers on yield attributing characters and economics of okra cultivation was evaluated. Application of highest dose of NPK @100% in combination with vermicompost (5 t ha -1 ) and biofertilizers with FYM increased the fruit yield of okra (cultivar Mahyco-10) considerably with yield varying between 80.00 q ha -1 to 227.13 q ha -1 and 80.49 q ha -1 to 229.62 q ha -1 during 2010 and 2011 respectively. In okra cv. Utkal Gaurav the fruit yield varied from 47.68 q ha -1 to 129.84 q ha -1 in 2010 and 47.27 q ha -1 to 131.35 q ha -1 in 2011. As regards the net return, highest net profit of Rs 87,630 and Rs. 89,370 ha -1 from the okra w as realized over an investment of Rs. 71,360 ha -1 during both the years with a benefit cost ratio of 2.23 and 2.25 when 100% NPK integrated with vermicompost @5t ha -1 and biofertilizers with FYM applied in okra cv.Mahyco-10. The highest net return of Rs. 14,350 in 2010 and Rs. 15,260 in 2011 with an investment of Rs. 63,550 each year was found in c ultivar Utkal Gaurav under highest level of nutrient application .
