Abstract: A field experiment was conducted during rainy (kharif) season of 2017 in split plot design with three replications at Crop Research centre, Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar to investigate the “Effect of zinc levels and moisture regimes on direct seeded rice”. The treatments consisted of four moisture regimes i.e. I₁-Irrigation at 1 day disappearance of ponded water, I₂- Irrigation at 3 days disappearance of ponded water, I₃- Irrigation at 5 days disappearance of ponded water, I₄-Irrigation at 7 days disappearance of ponded and 4 zinc level treatments i.e. Z₁-Control, Z₂-ZnSO₄ @25 kg/ha, Z₃-ZnSO₄@37.5kg/ha, Z₄- Foliar application of ZnSO₄@ 0.5% at tillering, pre-flowering and flowering. Test cultivar was Rajendra Neelam. The result showed that N, P, K and Zn content by grain and straw, were found to be maximum with I₁ moisture regime which were significantly superior to I₃ and I₄ but was statistically at par with I₂ in case of Zn content in grain and straw. N, P and K content in grain and straw were not influenced by moisture regimes.
