Field experiment was conducted in rice consisting of three moisture regimes (25, 50 and 75 mm irrigation) and four levels of zinc sulphate (0, 15, 30 and 45 kg ha−1) replicated thrice under factorial randomized block design. The grain, straw yield and the uptake of N, P and K by rice increased significantly with increasing levels of zinc up to 30 kg ZnSO4 ha−1. The relative uptake of zinc was higher at the first level of 15 kg ZnSO4 ha−1 rather than respective higher doses. A slight increase in the grain and straw yield of rice was observed with higher moisture regimes. The productivity and uptake of various nutrients by rice were highest at 30 kg ZnSO4 ha−1 and 75 mm of irrigation.
