EFFECT OF COWDUNG AND UREA FERTILIZATION ON THE PERFORMANCES OF MUNGBEAN VARIETIES

Abstract

The experiment was conducted at the research field of the Department of Crop Physiology and Ecology, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur during the period from August 2018 to November 2018 to evaluate the effects of cow dung and urea fertilization on growth, yield contributing characteristics and yield of mungbean varieties. The experiment comprised of two factors such as A:Four fertilization levels like, T1= no fertilizer, T2= 3kg cow dung plot-1 or 10 ton cow dung ha-1, T3= 16.2 g urea plot-1 or 54kg urea ha-1 T4= 1.5 kg cow dung plot-1 + 8.1g urea plot-1 or 5 ton cow dung ha-1 + 27kg urea ha-1 and factor B: two varieties such as, V1 = BARI mung-6 and V2 = BARI mung-8. All the seeds were sown in the experimental plots on 10 September 2018 following line-sowing methods. The unit plot size was 3 m2 (2m ×1.5m). The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replicates. The tallest plant, the highest number of leaves plant-1, the highest number of branches plant-1 , the highest number of pods plant1, the highest number of seeds pod-1, the longest pod, the maximum weight of 1000-seeds, and the highest seed yield, were recorded from T4 (5 ton cow dung ha-1 + 27 kg urea ha-1), while the application of T3

(54kg urea ha-1) ranked second for the avobe character in the present study.
