Nutrient Management

Major And Micro Nutrients


  • Use of culture and pelleting materials have revealed that inoculation increased the grain yield of pigeonpea
  • Inoculation with effective Rhizobium strains improved plant vigour
  • Roots of pigeonpea under uninoculated condition also produced nodules by natural Rhizobium present in the soil. Many of the natural Rhizobium present in the soil may belong to the strain which might induce nodule development but they fix little or no nitrogen.


  • The adequate supply of phosphorus is significant for higher yields of pigeonpea
  • In India, responses to phosphorus have been generally positive and in some areas , it is highly significant
  • Redgram crop planted in June responded up to 40 kg P2O5/ha whereas crop planted in mid-April responded up to 60 kg P2O5/ha. However, further increase in the level of phosphorus did not increase the yield.


  • Pigeonpea normally do not respond to potassium application unless grown on the soils low in available potassium.
  • The recommended nutrient for pigeon pea is 20 kg K2O/ha over 20 kg N+40kg P2O5/ha.

Micro Nutrients

  • Most of pigeonpea cultivars show susceptibility to Zinc deficiency. Soil application of 2-4 ppm zinc or foliar spray of 0.5 per cent zinc-sulphate with 0.05 per cent lime have proved effective in controlling zinc deficiency.
