A field experiment was conducted in sandy soil on mustard (Brassica juncea) with three levels of Zinc (Zn) viz. 0, 15 and 30 kg ZnSo4/hac and three levels of saline water irrigation (S) viz. 0.81, 8.05 and 12.09 dSm-1. Basal dose of N, P and K were @ 80 kg N/ha, 60 kg P2O5/ha, 40 kg K2O/hac respectively. The plant sample were taken at flowering stage, pod formation stage and maturity stage and analyzed for Zinc contents. The concentration of Zinc at flowering stage, pod formation stage, straw and grain at maturity and uptake of Zinc in grain and straw at maturity of Indian mustard increased significantly with increase in Zinc levels and decreased with increase in saline water irrigation levels respectively. Key words: Mustard, Saline irrigation and Zinc.
