An experiment was conducted at Horticultural Research Farm, School of Agriculture, ITM University, Gwalior, during summer 2019 to evaluate the effect of nitrogen and phosphorus on growth and yield of lady finger. The experiment was laid out in Randomized Complete Block Design with factorial arrangement having three replications. The treatment consisted of four nitrogen level sand three phosphorus levels. The results of experiment revealed that the different nitrogen and phosphorus levels, both significantly affected the various phonological characters viz., number of days to first flowering, number of days taken to 50 per cent flowering, number of days taken of first fruit picking, fruit characters like fruit length, diameter of the fruit, numbers of fruits per plant and fruit yield per hectare. The treatment combination consisting of application of nitrogen @ 150 kg/ha with combined application of phosphorus @ 75 kg/ha produced significantly maximum number of days to first flowering (46.48), number of days taken to 50 per cent flowering (48.17), number of days taken of first fruit picking (54.84), fruit length (15.66 cm). While, the treatment combination consisting of application of nitrogen @ 150 kg/ha with combined application of phosphorus @ 100 kg/ha produced significantly maximum diameter of fruits (2.36 cm), number of fruits per plant (22.36) and fruit yield per hectare (17.77) at maximum crop growth stage followed by application of nitrogen @ 150 kg/ha with combined application of phosphorus@ 75 kg/ha as compared to all the remaining treatment combinations. It is concluded that application of optimum level of nitrogen @ 150 kg/ha with combined application of phosphorus @ 100 kg/ha recorded the maximum plant growth and fruit yield of okra.
