Intercultural Operation
Weeds cause more than 50% reduction in the marketable yield of okra. Frequent weedings are necessary to keep the crop weed free. First weeding may be done at 15-20 days and second at 40-45 days after sowing to keep the crop weed free at critical stages. Germination commences in 10 to 15 days of sowing and it can be over in another week. Drip irrigation gives higher yield compared to furrow irrigation.

Harvesting
Pods are ready for harvesting in about 45 to 65 days after sowing depending on variety and season. Only tender and small fruits (6-10cm long) should be harvested preferably in the evening or morning. Pickings are taken at an interval of 3-4 days. Okra gives yield 80-100 q/ha in summer season and 125-150 q/ha in rainy season. Okra can be stored just for 2 to 3 days under room temperature conditions.
