Abstract: A pot culture experiment was conducted in a greenhouse at the SKUAST-K Shalimar. Polythene lined pots were filled with 5kg processed soils of each location in a randomized block design with three replications. Recommended doses of nitrogen, phosphorus and potassium @ 120, 60 and 30 mg kg-1 N, P and K, were applied through. Urea, DAP and MOP, respectively. The treatments consisting of four levels of zinc (0, 7.5, 1.5 and 2 mg Zn pot-1) applied through zinc sulphate. Among three zinc extrantants DTPA, HCL and ammonium acetate, only DTPA zinc extractant was significant and positively correlated with bray’s per cent yield and chemical properties such as pH, O.C and available nitrogen. The critical limit of zinc in soil and plant was found to be 0.64 and 22.0 mg kg-1, respectively. Among three extractants Zn extracted by DTPA was correlated significantly with brays percent yield (r=0.832**) and also significantly correlated with O.C(r=0.799**), CaCo3(r=0.965**), and N(r=0.978**).
