  • Sowing, thinning and gap filling

    Dibble the seeds at a depth of 4 cm along the furrow in which fertilizer was placed, and cover with soil. Put one seed per hole if germination is assured, otherwise two. If two were sown, keep only one healthy seedling per hole and remove the other 12–15 days after sowing. Where seeds have not germinated, dibble pre-soaked seeds (2 per hole) and irrigate immediately.

  • Intercropping

    In the source region, maize + cowpea or maize + blackgram intercropping is recommended for higher net returns in red lateritic soils, and maize + red gram for Vertisols (black soils).
