| Abstract: | A field experiment was performed to study the effect of zinc and iron supply on grain yield in four promising varieties of rice ( Oryza sativa L.) viz. IR-20, Jaya, Pusa 2–21, 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. |
