Manures and fertilizers. FYM N P 2 O 5 and K 2 O 8 tonnes 45 kg 22 kg each Whole amount of FYM, P, K and half N as basal dose , and rest N after one month of planting Irrigation –Moisture stress in both flowering and pod filling stage result in reduction of more than 70% in fruit yield. Crop should be irrigated every 5 th or 6 th day in summer. Weed control – proper weeding is required specially during rainy season. Three to fore hoeings are required first hoeing is done when seedlings are two weeks old and subsequent hoeings are done at fortnightly interval. Pre- emergence weedicides like pendimethalin are effective in weed control. Harvesting – okra fruits are continuously harvested every second or third day from first picking. The best time of picking is 6 -7 days after flowering. Average yield is 70 quintals per hectare.
