Abstract
A field experiment was conducted during kharif 2022 and 2023 to study the effect of iron and zinc biofortification on the growth and yield of drilled rice (Oryza sativa L.) at Krushi Vigyan Kendra, Navsari Agricultural University, Dediapada, Gujarat. The experiment was laid out in a randomized block design with ten treatments. Based on pooled analysis, almost all the growth attributes (periodical plant height, number of tillers plant-1, leaf area, leaf area index and dry matter accumulation plant-1), yield attributes (productive tillers m-2, number of filled grains panicle-1, panicle length, weight of panicle and 1000 grain weight), grain yield (3035 kg ha-1) and straw yield (5336 kg ha-1) were recorded significantly higher under treatment T10 (soil ZnSO4 + FeSO4 each @ 25 kg ha-1 and foliar ZnSO4 + FeSO4 each @ 0.5% at 30 & 60 DAS). Based on the results, it concluded that for achieving higher growth and yield in drilled rice, the crop should be fertilized with soil ZnSO4 + FeSO4 each @ 25 kg ha-1 and foliar ZnSO4 + FeSO4 each @ 0.5% at 30 & 60 DAS along with RDF and soil ZnSO4 + FeSO4 each @ 25 kg ha-1 along with RDF.
