Soil fertility management:

  • For spring season maize the recommended doses of Nitrogenous fertilizer can be splitted in 3 times i.e at 30, 45 and 60 days after seeding for the higher grain yield.
  • Maize hybrids produced the higher grain yield with 200:60:40 kg NPK/ha during winter in Terai.

  • Application of 180: 90: 60 N, P2O5 and K2O plus FYM 10 t/ha for full season maize was found profitable in terms of grain yield and economics.

  • Incorporation of Sunn hemp as green manure @ 7 t/ha of dry biomass within two months of sowing produced the good yield of winter maize and enhanced the soil nitrogen status.
