GROWTH AND YIELD OF HYBRID MAIZE AS INFLUENCED BY FERTILIZER MANAZEMANT

Abstract

An experiment was carried out at the Agronomy Field Laboratory, Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur during the robi season (December to May), 2012-13 to study the effect different organic and inorganic fertilizer on growth and development of hybrid maize (Denali). The experiment was laid out in Randomized Complete block Design with three replications with 30 plots. Ten fertilizer treatments (Tj= Compost, T,= Cow dung, T;= Poultry manure, T,= Recommended fertilizer dose, Ts= Compost + Half recommended fertilizer dose, T= Compost +Full recommended fertilizer dose, T7= Cow dung + Half recommended fertilizer dose, Ts= Cow dung + Full recommended fertilizer dose, T>= Poultry manure + Half recommended fertilizer dose, T;9= Poultry manure + Full recommended fertilizer dose. The recommended fertilizer dose was 500 Kg/ha urea + 250 Kg/ha TSP + 200 Kg/ha MP + 15 Kg/ha ZnSO, + 6 Kg/ha Boric Acid. And the rate of Compost, Cow dung and Poultry manure was 10t/ha. The effect of different manure and fertilizer dose on the yield and yield attributes were significant. The plant height, number of leaves/plant, weight of stem/plant, weight of leaves/plant, length of grain cob, weight/grain cob, diameter of grain cob, no. of grain/row, no. of total grain/cob, 1000-grain weight, yield/plant, yield/ha were significantly affected by fertilizer dose. The treatments T), T>, T3, Ts, Ts, Ts, T7, Ts, Ty and Tio were gave 10.16, 9.09, 8.49, 14.34, 13.35, 18.12, 11.99, 17.09, 11.40 and 15.98 t ha’, respectively. The T; Treatment gave higher yield (18.12) t ha’ and the T; treatment performed lowest yield (8.49 t ha’). The application of compost and full dose fertilizer is higher yielding. Balance nutrition with enough organic matter enrichment of the soil is the cause of this result.
