Abstract:
A field research was conducted at the Agronomy field of Sher-e-Bangla Agricultural
University, Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh during November, 2015
to March, 2016 in rabiseason to study the influence of variety and spacing in lentil
cultivation. The experiment was laid out in split plot design assigning three varieties
i.e. BARI Masur-5, BARI Masur-6 and BARI Masur-7 in the main plot and five
different spacing namely S
1
(30 cm × 10 cm), S
2
(20 cm × 20 cm), S
3
(30 cm × 30 cm),
S
4
(40 cm × 40 cm) and S
5
(50 cm × 50 cm) in the sub plot with three replications.
Recommended fertilizers @ 40 kg Urea, 80 kg TSP and 40 kg MOP per hectare,
respectively were applied in the experimental field. Results revealed that BARI
Masur-5 gave the highest no. of branches/plant (1.02, 5.00, 18.06, 29.93 and 30.90) at
20, 40, 60, 80 DAS and harvest, respectively, no. of leaflets/plant (217.4) at 80 DAS,
pods/plant (124.7), seed yield (1.04 t ha
-1
), stover yield (1.00 t ha
-1
) and biological
yield (2.04 t ha
-1
). On the other hand, among different spacing S
4
(40 cm × 40 cm)
gave the highest no. of branches/plant (1.24, 5.43, 18.37, 32.06 and 33.13) at 20, 40,
60, 80 DAS and harvest, respectively, no. of leaflets/plant (226.2) at 80 DAS and
pods/plant (151.2). But narrower spacing: S
1
(30 cm × 10 cm) scored the highest seed
yield (1.67 t ha
-1
) which was 74.25%, 61.07%, 52.69% and 35.32% higher than wider
spacing: S
5
(50 cm × 50 cm), S
4
(40cm × 40 cm), S
3
(30 cm × 30 cm) and S
2
(20 cm
× 20 cm), respectively, stover yield (1.22 t ha
-1
) and biological yield (2.89 t ha
) due
to more number of plants per unit area. Treatment BARI Masur-5 in combination with
S
1
(30 cm × 10 cm) produced the highest seed yield (1.82 t ha
-1
) which was 28.00%
and 8.79% higher than the treatment combination BARI Masur-7 and BARI Masur-6
along with S
1
(30 cm × 10 cm)
