An experiment was conducted at Race Course farm area of Agriculture college Gwalior during 1966–67 to find out the optimum requirement of okra crop for nitrogen, phosphorous and potash on sandy loam soil. It was found that height number of leaves, girth of the plants and yield of green pods was increased as the level of nitrogen added to the soil was increased from 22.5 kg. to 67 kg./ha. There is no significant differences on growth and development of okra crop due to these treatment effects. There was no beneficial effect of various levels of phosphorous and potash. However application of N P K increases the yield in general. Number of fruits and height of plant is positively correlated with the yield of crop.
