Abstract
A field experiment on dry direct sown rice was conducted for two consecutive kharif seasons during 2018 and 2019 at Agricultural College Farm, Naira, Srikakulam of North-Coastal zone of A.P. Significant differences were noticed in growth, yield and uptake of Zn and Fe by grain and straw due to weed control methods, nutrient management practices and application of micronutrients. Significant reduction in the total weed density and increased the crop growth parameters viz., plant height and SPAD meter readings and yield parameters viz., productive tillers m-2, grain and straw yield and uptake of Zn and Fe by grain and straw at harvest due to sequential application of pyrazosulfuron ethyl fb.florpyrauxifen-benzyl which was however, found parity with bispyribac sodium fb. 2,4-D amine salt + fenoxyprop-ethyl with safener. Weedy check registered the lowest values for all these parameters. Among nutrient management practices, application of 100% RDF produced taller plants, higher SPAD meter values and more number of productive tillers m-2, higher grain and straw yields. With regard to application of micronutrients, basal application of ZnSO4 @ 50 kg ha-1 exhibited significantly superior performance over other two treatments in this regard. Significantly higher uptake values for Zn by grain and straw were noticed with basal application of ZnSO4 @ 50 kg ha-1 whereas, foliar application of ZnSO4 @ 0.2% and FeSO4 @ 0.5% each at 20 and 40 DAS registered significantly higher uptake of Fe by grain and straw.
