Abstract:
An experiment on the performance of wheat - lentil mixed cropping under diikrent
seed rates of both wheat and lentil (100%. 90%. 80%. 70%. 60%, 50%. 40%. 30%.
20% and 10%. respectively) was conducted at the Agronomy Field. Sher-e-Bangla
Agricultural University. Dhaka-1207 during the period from November. 2006 to
March, 2007. The experiment was laid out in a randomized complete block design
with three replications. Results showed that significantly higher yields of wheat
(3.14.
2.92. 2.88 and 2.84 t hi', respectively) were obtained with the treatment of sole
wheat, wheat 90% + lentil 10%. wheat 80% + lentil 20% and wheat 70% + lentil 30%.
Signiticantly the highest combined yield of
3.21
t hi' was obtained with the treatment
of wheat 70% + lentil 30%. The highest land equivalent ratio, benefit-cost ratio and
total net return of 1.30, 2.14 and TIc 61026.75 hi'. respectively were obtained with
the treatment of wheat 70% + lentil 30%. It was concluded that lentil may he
intcrcroppcd with wheat using the combination of 70% wheat seed rate + 30% lentil
seed rate.
