ABSTRACT
The experiment was conducted at the farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from March to June 2012 to study the effects of cowdung and phosphorus on the yield and nutrient content of mungbean. The variety BARI Mung-5 was used as the test crop. The experiment consists of two factors: Factor A: Cowdung (3 levels),C0: 0 ton cowdung ha-1 (control), C1: 5 ton cowdung ha-1, C2: 10 ton cowdung ha-1. Factor B: Phosphatic fertilizer (3 levels); P0: 0 kg P2O5 ha-1 (control), P1: 20 kg P2O5 ha-1 and P2: 40 kg P2O5 ha-1. The two factors experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different yield and nutrient content parameters showed statistically significant variation for different levels of cowdung and phosphorus. In case of cowdung, the minimum number of days required for 80% pod maturity, the highest number of pods plant-1,the highest number of seeds pod-1, the maximum weight of 1000seeds, the highest seed yield and nitrogen, phosphorus, potassium and sulphur content in seeds were recorded from 10 ton cowdung ha-1. For phosphatic fertilizer, the maximum result was recorded from 40 kg P2O5 ha-1. Due to interaction effect of different levels of cowdung and phosphorus, the tallest plant, the highest number of leaves plant-1,the highest value was recorded from 10 ton cowdung ha-1 and 40 kg P2O5 ha-1, whereas in all cases the lowest value was recorded from 0 ton cowdung ha-1 and 0 kg P2O5 ha-1.
