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

= RFD (Recommended Fertilizer Dose);T
= RFD + Biochar

. 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

, pod length
(cm), number of seeds pod

-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.
