Abstract

An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

Highlights

Mungbean (Vigna radiata L.) known as green gram or golden gram is one of the most important pulse crops in Bangladesh
The largest area is covered by lentil (40.17%), and the mungbean is grown in only 6.34% (BBS, 2005)
Materials and Methods An experiment conducted in field farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of kharif season from April to June 2017, to determine the effects of nitrogen, phosphorus and potassium fertilizers on growth and yield attributes of mungbean

Summary

Introduction

Mungbean (Vigna radiata L.) known as green gram or golden gram is one of the most important pulse crops in Bangladesh. The cultivation of mungbean in Bangladesh is to increase and it covers [54, 57] and 68 thousand acres respectively in the 2008-2009, 2009-2010 and 2010-2011 fiscal years (BBS, 2011). Mungbean has special importance in intensive crop production system of the country for its short duration growing period (Ahmed et al, 1978). Cultivation of mungbean in the summer season could be an effective attempt to increase pulse production in Bangladesh. To meet up the condition, it is indispensable to make better the production scenario through varietal development and proper cultural and management practices as well as summer mungbean cultivation in Bangladesh
