Growth and Yield of Hybrid Maize as Influenced by Fertilizer Management

An experiment was carried out at the Agronomy Field Laboratory, Department ofAgronomy, Hajee Mohammad Danesh Science and Technology University, Bangladeshduring the rabi season (December to May), 2012-13 to study the effect of differentorganic and inorganic fertilizers on growth and development of hybrid maize (Denali).The experiment was laid out in Randomized Complete block Design with threereplications with 30 plots. Ten fertilizer treatments (T 1 = Compost, T 2 = Cow dung, T 3 =Poultry manure, T 4 = Recommended fertilizer dose, T 5 = Compost + Half recommendedfertilizer dose, T 6 = Compost + Full recommended fertilizer dose, T 7 = Cow dung + Halfrecommended fertilizer dose, T 8 = Cow dung + Full recommended fertilizer dose, T 9 =Poultry manure + Half recommended fertilizer dose, T 10 = Poultry manure + Fullrecommended fertilizer dose. The recommended fertilizer dose was 500 Kg ha -1 urea +250 Kg ha -1 TSP + 200 Kg ha -1 MP + 15 Kg ha -1 ZnSO 4 + 6 Kg ha -1 Boric Acid. And therate of Compost, Cow dung and Poultry manure was 10t/ha. The effect of differentmanure and fertilizer doses on the yield and yield attributes were significant. The plantheight, number of leaves per plant, weight of stem per plant, weight of leaves per plant,length of cob, grain weight per cob, diameter of cob, no. of grains per row, no. of totalgrains per cob, 1000-grain weight, yield plant -1 , yield ha -1 were significantly affected bydifferent manures and fertilizer uses with different doses. The treatments T 1 , T 2 , T 3 , T 4 ,T 5 , T 6 , T 7 , T 8 , T 9 and T 10 gave grain yield 10.16, 9.09, 8.49, 14.34, 13.35, 18.12, 11.99,17.09, 11.40 and 15.98 t ha -1 , respectively. The T 6 Treatment gave higher grain yield(18.12) t ha -1 and the T 3 treatment performed lowest grain yield (8.49 t ha -1 ). Theapplication of compost and full dose fertilizer is higher yielding. Balance nutrition withenough organic matter enrichment of the soil is the cause of this result.
