Abstract:
A field experiment was conducted at the Research Field, SAU, Dhaka, in the Kharif-II season during the period from August 2013 to November 2013 to study the effect of row spacing and growth regulator (NAA) on growth and yield of mungbean. The experiment consists of four levels of NAA viz. 0, 20, 40 and 60 ppm and three different spacing viz. 20cm × 10cm, 30cm × 10cm and 40cm × 10cm. The experiment was laid out in randomized complete block design with three replications.The result indicated significant variations in plant height, number of branches plant-1, leaf dry weight, stem dry weight, root dry weight, number of pod plant-1, pod length,number of seed plant-1, weight of 1000 seeds, grain yield,stover yield, biological yield and harvest index due to row spacing and/or plant growth regulator (NAA). The treatment combinations,the maximum plant height,number of branches plant-1, leaf dry weight, stem dry weight, root dry weight and leaf area index were recorded with 30cm × 10cm when treated with 40 ppm NAA irrespective of growing period. This combination also exhibited maximum number of pods plant-1, longest pod length and maximum number of seed pod-1. The maximum weight of 1000 seeds, highest grain yield and harvest index were found when mungbean was sown with row spacing in30cm × 10cm when treated with 40 ppm NAA.
