EFFECT OF BORON AND MAGNESIUM ON THE YIELD AND QUALITY OF MUNGBEAN SEED

Abstract

An experiment was carried out to investigate the effect of boron and magnesium on the yield and quality of Barimung 5 at the Agronomy Field Laboratory, HSTU, Dinajpur during the period from March 2006 to April 2007. The experiment compaired of three levels of boron viz. no boron (Bo), 5 kg ha’ (Bs) and 10 kg ha” (Byo) boron and four levels of magnesium viz. no magnesium (Mgp), 5 kg ha”! (Mg;), 10 kg ha’! (Mgio) and 15 kg ha’! (Mgis) magnesium. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. From the study it was observed that boron significantly increased yield and yield contributing characters except pod length (cm) and quality parameters under investigation. Result revealed that among the three boron levels B; treatment showed significantly superior effect on yield (1103.00 kg ha’), pods plant” (18.13), seeds pod’! (9.13), 1000 grain weight (31.98), (%) protein content of seeds, % germination and vigour index. On the other hand magnesium showed significant effect on yield and few yield contributing characters and quality parameters under investigation. Among the four levels of magnesium, Mg; treatment produced the highest yield (1111.00 kg ha"), pods plant’' (18.01), seeds pod! (9.76), 1000-grain weight (31.99), (%) protein content of seeds (21.08 %), % germination and vigour index (%). But their interaction the treatment B; x Mg; performed the best result in terms of yield (1415.33 kg ha”), pods plant (20.33), seeds pod” (12.23), 1000 grain weight (33.18 g), protein content of seeds (23.85 %) and % germination but incase of vigour index only February month gave non significant result. At the same time control treatment showed the poorest results in every aspects. Thus the present study clearly indicates that 5 kg B ha’! and 5 kg Mg ha’ might be applied for increasing yield and quality of commercially cultivated mungbean seeds.
