EFFECT OF SOWING DATE AND SPACING ON GROWTH AND YIELD OF MUNGBEAN

Abstract

The experiment was conducted at Sher-e-Bangla Agricultuml University farm, during August 2013 through January, 2014 of kizarif II season to evaluate the effect of sowing date and spacing on growth and yield of mungbean (Vigna radiaza L. Wilczek). The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatments were four sowing dates as 5, (24 August), S2 (13 September), S (03 October) and 54 (23 October), respectively and three spacing as P, (20cm x 10 cm), P2 (30 cm x tO cm) and P3 (40cm BARI Mung - 6 was the plant material of the experiment. Data on growth and yield parameters were recorded from vegetative growth to maturity period. The results revealed that all the growth and yield attributes were significantly influenced by different sowing date and spacing and their interaction. Ilighest plant height (cm), no. of branches plant', no. of leaves plant', dry weight (gm), no. of pods plant', pod length (cm), no. of seeds pot', weight of 1000 seed (g), seed yield (t ha'), stover yield (t ha-'), biological yield (t ha") and harvest index (%) was observed in S2 (13 September), where as the minimum was in S4 (23 October) over different spacing. The highest seed yield (1.53 t ha-') was obtained from S2 (13 September) with P: (30cm 10 cm) treatments and lowest was found in S4P3 (sowing on 23 October and spacing at 40 cm x 10 cm). From the results of the experiments, it could be concluded that in Kharif It season sowing on 13 September with 30 cm x 10 cm). x 10 cm spacing was optimum for obtaining higher grain yields of mungbean. Delay sowing reduced the yield of mungbean due to unfavorable condition for growth and dcvclopmcnt.
