Abstract:
An experiment was conducted at the Agronomy Field, Sher-e-Bangla
Agricultural University. Dhaka from March 2007 to July 2007 to observe the
influence of harvesting time on growth and yield of mungbean varieties. The
treatments were five harvesting times viz. 15, 20,
25,
30 and 35 days after
anthesis (DAA) and two mungbean
( Vigna radiaza)
varieties viz. BAR! mung
6
-
and Sona mung. The purpose of this experiment was to determine appropriate
planting time of summer mungbean in the cropping pattern after identiing the
best harvesting time. The varieties behaved differently at different harvesting
dates. Delayed harvesting increased the yield of BARI mung 6 but reduced the
yield of Sona mung. The highest seed yield (1.66
1
had
) was obtained from
BAR! mung 6 harvested at 35 DAA that was similar at 30 DAA (1.63 t haj,
20 DAA (1.42 thi') and 25 DAA (1.41 t hi') of the same variety. The lowest
seed yield (0.57 t hi') was obtained from Sona mung harvested at 15 DAA and
35 DAA. The higher yield might be due to better yield contributing character of
the two varieties harvested at above mentioned maturity period.
