Abstract: The present study was aimed to optimize phosphorous and zinc doses to maximize wheat productivity under arid climate. Varying levels of phosphorus (P1= 60, P2 = 90 and P3 = 120 kg ha -1 ) and zinc (Zn1 = 10, Zn2 = 15 and Zn3 = 20 (kg ha -1 ) were applied in a silty loam to which wheat was grown till maturity. From the results of the present study, it was found that application of P had a positive influence on growth and grain yield of wheat. However, maximum growth and yield of wheat was recorded at 120 kg ha -1 P2O5 application. In contrast, Zn application did not change in growth or yield of wheat. However, combined application of P and Zn caused an increase in growth of wheat particularly in terms of Leaf Area Index (LAI). The highest grain-P content was recorded with application of 120 kg ha -1 P2O5 and 15 kg ha -1 Zn while highest straw-P was accumulated with comparatively lower rates of both (90 kg ha -1 P2O5 and 15 kg ha -1 Zn). The highest grain and straw-Zn contents were recorded for 15 kg Zn ha -1 with 60 and 90 kg ha -1 P2O5, respectively. Combined application of 120 kg P2O5 and 20 kg ha -1 Zn depicted the highest NFB and BCR during both cropping seasons.
