摘要：
A field experiment was performed to study the effect of zinc and iron supply on grain yield in four promising varieties of rice (Oryza saliva L.) viz. IR-20, Jaya, Pusa 2-2;, and IET-1444. Three doses of ZnSO4 or FeSO4 (0, 20 or 40 kg ha(-1)) along with all possible combinations were investigated. The varietal differences were significant in grain yield ha(-1). The grain yield increased with the dose of zinc and Jaya but not significantly in IR-20. The increase in grain yield was more significant and dose dependent in IET-1444 than in Jaya in response to iron application.
