Abstract: This present study was performed at the Department of agriculture chemistry and soil science, A. S. (P.G.) College, Lakhaoti (Bulandshahr), Uttar Pradesh, during kharif seasons of 2005 and 2006. The experimental design aimed to study the response of okra to different phosphorus and zinc fertilizer levels under two levels of soil salinity (EC). The obtained results from the two years showed that increasing level of phosphorus and zink up to 90 and 40 kg ha-1, repectively increased green and dry pod yield of okra while soil salinity decreased yield dramatically due to osmotic stress. Results showed that the phosphorus uptake by the crop significantly increased by different phosphorus level. A consistent increase ire phosphorus uptake by okra pods was noticed with increasing levels of phosphorus and a maximum value (60.3 and 73.4 mh/pot) was recorded under 90 kg P2O5 ha-1 under normal condition (4 dSm-1). This indicated increasing soil salinity (8dSm-1) reduced the uptake of phospuorus and zinc because showing an antagonistic effect on the absorption of phosphorus and zinc by the crop.
