Cultivation Of Green Manure

Cultivation Of Green Manure:

The Punjab agriculture department is promoting the cultivation of green manure these days as Punjab Agro is providing subsidy on the seed at the rate of Rs 2,000 per quintal, which costs Rs 6,300 per quintal without subsidy.

  • Green manures are crops grown specifically for maintaining soil fertility and structure.
  • They are normally incorporated back into the soil, either directly, or after removal and composting.
  • There are three main varieties of green manure, including Dhaincha, Cowpea, Sunhemp.
  • Also some crops such as summer moong, mash pulses and guar act as green manure.
  • Green manure varieties are incorporated into the soil when the crop is 42-56 days old.
  • Green manure must be leguminous in nature, bear maximum nodules on its roots to fix large amount of atmospheric nitrogen in the soil.
  • It helps in enhancing the organic matter in the soil, meets the deficiency of the micronutrients and reduces the consumption of the inorganic fertilisers etc.
