Abstract:
The experiment was conducted to find out the effect of intercropping chickpea with
sunflower under different row and spacing arrangements at the experimental field of
Agronomy Department of Sher-e-Bangla Agricultural University, Dhaka- 1207, during
the period from November 2008 to March 2009. Seeds of sunflower variety DS-1
(Kironi) and Chickpea variety BARI-Chola-5 used as a test crop for the study. The
experiment consisted of nine row arrangement combinations of sunflower and
chickpea plus sole treatment of both the crops. The row arrangement of sunflower
were recommended as 50 cm apart, paired rows 30 cm apart followed by 70 cm gap;
and paired rows 30 cm apart followed by 100 cm gap. Within these were three row
arrangements, 1-4 rows of chickpea at different spacing which altogether made nine
treatment combinations. Results revealed that soil moisture, light intensity, growth
parameters, yield attributes and yield, land equivalent ratio, soil pH and N, P. K had
significant differences. The maximum soil moisture (30.11-35.20%) was recorded
when two rows of chickpea were sown 40 cm apart in 70 cm gap of sunflower paired
rows. svhile the minimum (25.10-27.60%) in the sole sunflower plots. The highest
LER (1.76) was recorded from T
5 and the lowest LER from the sole crop both
sunflower and chickpea. The highest equivalent yield (BY) of sunflower (3.81 t haj
was recorded from T
5 and the lowest (2.09 t hi') from the sole crop of chickpea. The
highest EY of chickpea (4.39 t haj was recorded from T5 and the lowest
(2.57
t hi')
from the sole crop of sunflower. The highest combined yield of sunflower and
chickpea (4.08 t hi') was recorded from T
5 and the lowest (2.23 t hi') from the sole
crop of sunflower. The highest benefit cost ratio (3.52) was recorded from 'f
s and the
lowest (1.49) from the sole crop of chickpea.
