Response of okra (Abelmoschus esculentus L.) to varying ‘evels of plant spacing (60 × 20,60 × 30 and 60 × 40 cm) and graded levels of nitrogen (0, 50, 100 and 150 kg N/ha) and phosphorus (0, 30 and 60 kg P/ha) was studied on sandy loam soil poor in organic carbon, medium in available phosphorus and rich in available potassium during kharif seasons of 1972, 1974 and 1977 at the Indian Institute of Horticultural Research, Bangalore. The closest spacing (60 × 20 cm) gave consistantly higher yields in all the years of study. Nitrogen and phosphorus fertilization increased plant height, number of nodes per plant and fruit size which finally contributed in increasing the fruit yield. Application of 100 kg nitrogen and 60 kg phosphorus per hectare gave the highest yield as compared to other levels.
