EFFECT OF BIOCHAR ON GROWTH AND YIELD OF MUNGBEAN ( BARIMung-6 )

Abstract

This research work was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka during the period from March, 2017 to July, 2017 to study the growth and yield of mungbean (BARI Mung-6) as influenced by different levels of biochar. The experiment comprised of the following 8 treatments as T 1 = Control,T 2 = RFD (Recommended Fertilizer Dose);T = RFD + Biochar @ 2 ton ha -1 T 4 = RFD + Biochar @ 4 ton ha ii

-1 ;T 5 3 = ⅔of RFD + Biochar @ 2 tonha -1 ; T 6 = ⅔ of RFD + Biochar @ 4 ton ha -1 ; T = ½ of RFD + Biochar @ 2 ton ha -1 ;T 8 = ½ of RFD + Biochar @ 4 ton ha -1 7 . The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. From the research field, the maximum plant height (44.70 cm) was recorded from T treatment, which was statistically identical with other treatments whereas, the minimum plant height (37.57 cm) was recorded from T treatment. The maximum number of branches plant-1, number of pods plant 1 , pod length (cm), number of seeds pod -1 -1 , weight of l000-seed (g) was recorded from T treatment, which was statistically identical with other treatments whereas, the minimum plant height was recorded from T treatment. In addition, yield of grain ton per ha significantly varied among the different levels of biochar applications (Table 4).On the one hand the highest grain yield (1.40 t ha 1 ) was obtained from T 3 (RFD + Biochar @ 2 ton ha -1 ) treatment, which was followed by T 4 (1.29 t ha -1 ) and lowest grain yield (0.83 t ha -1 -1 ) was obtained from T (control) treatment. On the other hand, in all the cases lower values were found in the control treatment. From this study, it may be concluded that biochar had significant positive effect on growth and yield of mungbean.
