Abstract

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 was 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 cultivar Utkal Gaurav under highest level of nutrient application.
