Initial cultivation should be deep to allow better and faster root development. Aggressive perennial weeds should be removed before planting. Early land preparation is recommended to expose pests to sunlight and birds. Land should be dry to avoid soil crumbling and creation of a hard pan. Incorporating of crop residue can significantly increase the soil organic content. Well decomposed and powdered organic matter at the rate of 10-30 t/ha is incorporated in the soil at the time of final ploughing.
