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

Abstract

An experiment was carried out at the field Laboratory of the Department of Agronomy, HSTU, Dinajpur from April to July 2006, and the Laboratory experiments from November 2006 to March 2007 to investigate the effect of sulphur and boron on yield and quality of mungbean variety BARIMUNG- 5. Four sulphur levels (viz. 0,15,30,45 kg ha’) and three boron levels (viz. 0, 5, 10 kg ha’') were included as the treatment. Results of the experiment revealed that different levels of sulphur and boron had significant effect on yield, yield attributes and quality of mungbean seed. Result also revealed that sulphur 30 kg and boron 5 kg ha’ significantly increased plant height, number of branches plant’, number of pods plant’, number of seeds pod™', 1000 seed weight, seed yield (kg ha’) and different seed qualitative characteristics viz. protein content (%), germination (%) and vigour index . Among the different doses of sulphur 30 kg and boron 5 kg ha” was the best in respect of yield contributing characteristics and all the qualitative characteristics (except % moisture content). In contrast, control (0 kg Sx0 kg B ha’') showed the poorest performance in respect of yield and quality of mungbean seed. The highest yield and quality seed was found in 30 kg S ha'x5 kg B ha’ and the lowest in control. The present study clearly indicates that 30 kg S ha’! and 5 kg B ha” could be applied for increased yield and quality of mungbean seed.
