Maize is an annual grass in the family Gramineae
Maize or Indian corn (called corn in some countries) is Zea mays, a member of the grass family Poaceae. It is a cereal grain which was first grown by people in ancient Central America.
Chisel the soil having hard pan formation at shallow depths with chisel plough at 0.5 M interval first in one direction and then in the direction perpendicular to the previous one once in three years. Apply 12.5 t/ha of FYM or compost or composted coir pith besides chiselling, to get an additional yield of about 30% over control.
Application of Fym or Compost
Spread 12.5 t/ha of FYM or compost or composted coir pith evenly on the unploughed field along with 10 packets of Azospirillum (2000 g/ha) and incorporate in the soil.
Application of Fertilizer
- Apply NPK as per soil test recommendation as far as possible. If soil test recommendation is not available, adopt a blanket recommendation of 60 : 30 : 30 NPK kg/ha for Alfisols and 40 : 20 : 0 NPK kg/ha for Vertisols.
- Apply half of N and full dose of P2O and K2O with enriched FYM as basal along with Azospirillum (10 packets/ha).Top dress remaining half of N at tasseling
Select good quality seeds. Adopt the seed rate @ 20 kg/ha for hybrids and 25 kg/ha. for varieties
Adopt a spacing of 45 cm between rows and 20 cm between plants in the row.
Population : 10 – 11plants/m2
Pre-Treatment of Seeds with BioFertilizer
Seeds treated with fungicides may be treated with three packets (600 g/ha) of Azospirillum
Dibble or drill the seeds at a depth of 4 cm.
- Intercropping system of maize + cowpea or maize + blackgram is recommended for higher net returns in the red lateritic soils of Southern districts.
- For Vertisols of Southern district, maize + redgram intercropping systems is ideal.
