GROWTH AND YIELD OF MUNGBEAN (BARI Mung 5) (Vigna radiata) IN RESPONSE OF NITROGEN AND BORON

Abstract

The experiment was conducted at the research field, SAU, Dhaka, in the Robi season during the period from March 2014 to June 2014 to study the effect of nitrogewn and boron on growth and yield of mungbaen. The experiment consists of four levels of nitrogen viz. control, 25 kg N ha -1 , 35 kg N ha -1 and45 kg N ha and three levels of boron viz. control, 1 kg B ha -1 and2 kg B ha -1 . The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. In case of different levels of nitrogen, the highest number of pods per plant(24.89), length of pod (9.68 cm), number of seeds per pod (14.67), 1000 grains weight (44.50), grain yield (1.68 t ha -1 ) and harvest index (56.42 %) were found from N . For different levels of boron, the highest number of pods per plant(22.08), length of pod (10.18 cm), number of seeds per pod (15.47), 1000 grains weight (44.26), grain yield (1.63 t ha -1 ) and harvest index (55.71 %) were found from B . Amongthe interaction effect, the number of pods per plant(26.33), length of pod (11.53 cm), number of seeds per pod (17.80), 1000 grains weight (49.70), grain yield (2.0 t ha ) and harvest index (68.97 %) were observed from N 2 B .In this study it was found that N 2 B 1 1 always gave better result over yield and growth parameter of mungbean. So this combination of nitrogen and boron is suggested for better result on mungbean cultivation.
