Abstract
Different environmental stresses can cause different kinds of diseases in crops plant which is a very serious threat for the globe like stunting of growth, chlorosis, necrosis, deficiency of nutrients and decreasing the relative water content of leaf. Nitrogen forms the main constituent of chlorophyll and it maintains a balance in the process of photosynthesis. Phosphorus, which is associated with the ability of the plant to store and use energy. To find out the effect of nitrogen and phosphorus we treated okra plant by different concentration of nitrogen and phosphorus using randomized complete block design with three replications in agriculture research station, Swabi in 2022. Five level of phosphorus and nitrogen were applied to okra seeds at rates of (0-0, 100-20, 100-40, 100-60, and 100-90) N-P2O5 Kgha-1, respectively. Result revealed that the yield and yield parameters of the okra crop were significantly impacted by various combinations of treatments. For treatments 100-20, 100-40, 100-60, and 100-90 kgha-1, the okra plant’s mean yield was 8.86, 11.85, 10.25, and 8.07 Kgha-1, respectively, whereas the production of the control group was 6.62 Kgha-1. The optimal NP fertilizer rate was 100-40, which ensued much better yield than the other NP fertilizer levels that were assessed. Our finding suggested that an okra crop could benefit from a fertilizer dose of 100-40 N and P2O5 Kgha-1.
