Abstract:
A field experiment was conducted at Sher-e-Bangla Agricultural University farm,
Dhaka during the period from November 2008 to February 2009 to study the effect
of irrigation and variety on growth and yield of lentil. The experiment was consisted
of two treatment factors; factor A: four irrigation levels (!= no irrigation,
11=
irrigation at
25
DAS, 12= irrigation at 50 DAS and 13= Irrigation at both 25 and
50
DAS) and factor B: four lentil varieties ('i= BARI Masur-3.
V2=
BARI Masur-4,
V3
= BARI Masur-5 and V
4
= BARI Masur-6). The experiment was laid-out in split
plot design with three replications assigning irrigation level in the main-plot and
variety in the sub-plot Results showed that irrigation level, variety and their
interaction exerted significant influence on plant height and plant dry matter at
different days after sowing (DAS), on pods plani', seeds per pod', 1000-seed
weight, seed yield, stover yield, biological yield and harvest index of lentil.
Increasing irrigation level increased seed yield. BARI Masur-6 gave the highest seed
yield followed by BARI Masur-5, BARI Masur-4 and BARI Masur-3. Irrigation at
both 25 and
50
DAS in BARI Masur-6 showed the highest seed yield. In all the
cases, increasing seed yield were obtained by increasing the values of the said
parameters.
