Abstract:
An experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural
University, Dhaka, during November 2017 to February 2018 to assess growth and
yield variations of mustard and lentil under intercropping systems. Twelve treatment
combinations were T

= Sole Mustard, T

= Sole Lentil, T
= 50% Mustard + 50%
Lentil, T

= 1 Row Mustard + 1 Row Lentil, T
= 2 Rows Mustard + 1 Row Lentil, T

= 3 Rows Mustard + 2 Rows Lentil, T
= 70%
Mustard + 30% Lentil, T
11
= 80% Mustard + 20% Lentil, T
= 90% Mustard + 10%
Lentil. The experiment was conducted in Randomized Complete Block design with
three replications. The experimental materials were Mustard (BARI Sharisha-16) and
12
Lentil (BARI Masur-7). Seeds of these crops were sown on 1 November 2017 and
harvested on 31 january 2018. Growth, yield, productivity and economic
performance were studied. Results revealed that, intercropping system significant by
effect on plant height, above ground dry matter plant

Intercropping reduced the sole
mustard yield but economic analysis showed highest gross return (Tk. 213600 ha
),
net return (Tk. 103680 ha

), and monetary advantage (Tk.87952.94 ha
) were
obtained from T
(One row mustard with one row lentil) which was an agronomic
advantage compensating the yield losses in mustard under intercropping system. The
higher economic values eventually determined the maximum benefit-cost ratio (1.94)
compared with BCR (1.61) for mustard normal planting. In this intercropping
system, one row mustard with one row lentil showed better compatibility than other
when mustard and lentil are intercropped.
