1. Lower seedling density in nursery using only 40 gm seed/m2 to produce thick, healthy seedlings(40 to 50 kg /ha).
2. Correcting zinc deficiency and adding 50% more p and k in the nursery then recommended.
3. Row seeding, preferably dibbling, 20x15 cm behind plough or seed-drill.
4. Seeding time first fortnight of june for alluvial soils & second fortnight of june for laterites.
