Abstract:
The field experiment was conducted at the Horticulture Ilirni of Sher-e-Bangla
Agricultural University. Dhaka during the period from October, 2007 to January, 2008 to
study the performance of nitrogen and moisture management techniques on growth and
yield of kohirabi. The trial consisted of four levels of nitrogen fertilizer, viz., No: 0; N
1 :
80: N
2: 160: N
3
: 240 kg N/ha respectively and five different moisture management
techniques. viz., M
1;
: No moisture management; M
1
: Straw mulch; M2: Water hyacinth
mulch; M
3
: Black plastic mulch; M
4
: Three times of irrigation. The experiment was
carried out in randomized complete block design with three replication. Most of the
parameter varied insignificantly as influenced by the application of moisture management
techniques and nitrogen fertilizer. Maximum marketable yield (35.9 t(ha) was obtained
from N
3
and the lowest (24.5 hIm) was obtained with N
o . For moisture management, M
2
produced the highest yield
(35.4
i/ha) and the lowest yield (27.4 hJha) was recorded from
M0
. Combination of N
3M2
gave the highest yield (41.3 tlha) and the lowest (12.9 hlha)
was received from N
0M13
. Benefit cost ratio was maximum (3.9) in the treatment
combination of N
3M2
and the lowest (1.4) was in control treatment. So. 240 kg N/ha with
water hyacinth was best for growth and yield of kohirabi.
