INFLUENCES OF ORGANIC MANURES AND INORGANIC FERTILIZERS ON GROWTH, YIELD & NUTRIENT CONTENT OF MUNGREAN (BAR!Mung 5)

Abstract

An experiment was conducted during the period from February to April of 2012 at the experimental field of Sher-e-Bangla Agricultural University to study the effect of organic and inorganic fertilizers on growth .yield and nutrient content of mungbean (BARI Mung 5) using RCBD (Randomized Completely Block Design) with three replications. During the experiment, following treatments were incorporated .Treatments T, —Control. T, - Cowdung 10 t ha-1 (Recommended dose), T2 - Cowdung @ 6 t ha" + 25 % of optimum dose of inorganic Fertilizers. 13— Cowdung @ 6 t ha" + 50% of optimum dose of inorganic fertilizers, i - Cowdung @6 t ha" + 75% of optimum dose of inorganic fertilizers, T5 -Vermicompost 7 t ha" (Recommended dose). T5 - Vermicompost @ 4 t ha" + 25% of optimum dose of inorganic fertilizers. T7 - Vermicompost @ 4 t ha" + 50 % of optimum dose of inorganic fertilizers. T8 - Vermicompost ® 4 t ha" + 75 % of optimum dose of inorganic fertilizers, 19- 100 % Inorganic Fertilizers were tested. At harvest the highest plant height, number of leaves plant" and branches plant" were found from the Vermicompost Ca, 4 t ha" + 75 % of optimum dose of inorganic fertilizers which was statistically similar or closely followed by Cowdung @ 6 t ha" + 75% of optimum dose of inorganic fertilizers. Maximum numbers of pods plant", seeds pod" and seeds plant" were also recorded in Vermicompost @ 4 t ha" + 75 % of optimum dose of inorganic fertilizers and it was statistically similar with or closely followed by Cowdung @ 6 ha" + 75% of optimum dose of inorganic fertilizers. The highest seed yield plant", 1000seed weight and seed yield ha" were also recorded in Vermicompost Oa, 4 t ha" + 75 % of optimum dose of inorganic fertilizers and it was statistically similar with the treatment of Cowdung @6 t ha'' + 75% of optimum dose of inorganic fertilizers. It was observed that. I br the above parameters; even Vermicompost @ 4 t ha" + 25% of optimum dose of inorganic fertilizers and Cowdung @6 t ha-1 + 50% of optimum dose of inorganic fertilizers showed better results than sole 100% inorganic fertilizers. The lowest values for all of the growth and yield parameters were obtained from the treatment using no fertilizers. The highest N. P and K contents in seed were recorded in Vermicompost @ 4 t ha" ± 75 % of optimum dose of inorganic fertilizers and it was statistically similar with or closely followed by Cowdung 6 t ha" + 75% of optimum dose of inorganic fertilizers. The lowest N, P and K contents of mungbean seed were found from the treatment using no fertilizers that is control treatment.
