Abstract: A field 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 levels viz., 75 kg/ha (N1), 100 kg/ha (N2), 125kg/ha (N3) and 150kg/ha (N4) and three phosphorus levels i.e., 75 kg/ha (P1), 75 kg/ha (P2) and 75 kg/ha (P3). The results of experiment revealed that the different nitrogen and phosphorus levels, both significantly affected the plant height, number of branches per plant, number of leaves per plant, number of nodes on main stem, internodal length and fruit yield per hectare. The treatment combination consisting of application of nitrogen @ 150 kg/ha with combined application of phosphorus @ 100 kg/ha produced significantly maximum plant height(141.99 cm),number of branches per plant (2.85), number of leaves per plant (22.91), number of nodes (19.23cm), length of internode (8.42cm) 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.
