Sowing and seed rate
The seed rate is 15 kg/ha. Tall varieties of arhar should be sown in rows at a distance of 50 cm while dwarf varieties like HPA-92 should be shown at 30-35 cm row spacing with seed to seed spacing of 15-20 cm. The crop gives much higher yield if, it is sown in last week of May. One row of mach can also be successfully grown in between two rows of arhar.
In Zone I, paired row planting of arhar and sesamum gives higher return. In case of paired row planting, two rows of arhar should be sown at 30 cm spacing followed by two rows of sesamum sown at 20 cm spacing. The seed rate and fertilizer doses to the sesamum crop should be reduced to half of the recommended for pure sesamum crop.
