Abstract:
A field experiment was conducted at the Agricultural College and Research Institute, Killikulam, to focus on the effect of various micronutrient methods on growth, yield and nutrient uptake of hybrid maize COH (M) 8 during Summer 2021. The experiment was laid out in Randomized Block Design consisting of 10 treatments and replicated thrice. The treatments included the application of micronutrients in the form of soil and foliar applications of zinc sulphate, ferrous sulphate, soil application of maize maxim and also a micronutrient mixture enriched FYM. The observations that were recorded are growth parameters (plant height, days to 50% tasselling and silking, dry matter production), yield parameters (cob length, cob girth, number of rows per cob, number of grains per row, no of grains per cob, grain yield and stover yield) and nutrient uptake in plants. The results revealed that the application of 1% Zinc and Ferrous sulphate (T₇) has proven to be an effective one in terms of growth, yield parameters, and uptake of nutrients in plants. This treatment produced a higher plant height (287.31 cm), dry matter production (17288 kg ha^-1), grain yield and stover yield of 7298 kg ha^-1 and 9844 kg ha^-1 respectively and also registered higher nutrient uptake (101.61 kg ha^-1, 9.87 kg ha^-1, 108.53 kg ha^-1) N, P, K respectively.
