PERFORMANCE OF WHEAT - LENTIL MIXED CROPPING UNDER DIFFERENT SEED RATE RATIO

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.
