    Sowing

Transplanted crop

  • Apply NPK fertilizers as per soil test recommendations. If soil test recommendations are not available, adopt a blanket recommendation of 90 N, 45 P2O5, 45 K2O kg/ha.
  • Apply N @ 50:25:25 % at 0, 15 and 30 DAS and full dose of P2O5 and K2O basally before planting
  • In the case of ridge planted crop, open a furrow 5 cm deep on the side of the ridge at two thirds the distance from the top of the ridge and place the fertilizer mixture along the furrow and cover with soil upto 2 cm.
  • Soil application of Azospirillum at 10 packets (2 kg/ha) and 10 packets (2000g/ha) of phosphobacteria or 20 packets of Azophos (4000g/ha) after mixing with 25 kg of FYM + 25 kg of soil may be carried out before sowing/planting.
Direct sown crop
  • Apply NPK fertilizers as per soil test recommendations as far as possible. If soil test recommendations are not available, adopt a blanket recommendation of 90 N, 45 P2O5, 45 K2O kg/ha.
  • Apply N @ 50:25:25 % at 0, 15 and 30 DAS and full dose of P2O and K2O5 basally before sowing and if basal application is not possible the same could be top dressed within 24 hours.
  • In the case of bed planted crop, mark lines to a depth of 5 cm and 45 cm apart.  Place the fertilizer mixture at the depth of 5 cm along the lines. Cover the lines upto 2 cm from the top before sowing.
  • In the case of sorghum raised as a mixed crop with a pulse crop (Blackgram, Greengram or Cowpea) open furrows 30 cm apart to a depth of 5 cm.
  • Apply fertilizer mixture in two lines in which sorghum is to be raised and cover upto 2 cm.
  • Skip the third row in which the pulse crop is to be raised and place fertilizer mixture in the next two rows and cover upto 2 cm with soil.
  • Application of bio-fertilizers: When Azospirillum is used apply only 75% of recommended N for irrigated sorghum.
  • Soil test based fertilizer recommendation may be adopted in Western and North Western Zone viz., Alfisol, Inceptisol and Vertisol for prescribing fertilizer doses for specified yield targets.
