Abstract: Two year pot experiment were conducted in green house to study the effect of phosphorus doses viz-P-40,P2-80; P3-120 kgha-1. Four levels zinc sulphate viz-Control, Zn1-25, Zn2– 50 and Zn3-75 kgha-1and three levels of water salinity viz-ECo- Control EC1 8, and EC2-16 dSm-1, significantly decreased grain yield with increasing levels of salinity yet increased higher dose of P and Zn. The maximum grain yield was recorded at P2 (80 p2O5kg ha-1) and Zn2 (50 kg ZnSo4 kgha-1) and yield to extent of 19.04 and 28.96% and 46.11 and 43.24% during 1st and 2nd years respectively. The incensement of EC significantly decreased P.K. Ca and Zn increased N and Na content (%). The P and Zn application significantly increased the N,K and Ca. However incensement doses of P increased P content (%) but Na & Zn content (%) decreased. While zinc sulphate application enhanced the Zn content (%) and decreased that of P and Na contents.
Keywords: EC, N; P; K, Ca, Na, Zn, Content (%), yield and salinity
