Blackgram

Water Management

  • The crop cannot tolerate long dry spell and therefore, irrigations are very useful for urd. The crop should be irrigated at flowering and pod filling stages but the water should not accumulate in the field.
  • One pre-sowing irrigation at the time of seedbed preparation is required to ensure good germination, if the land is dry.
  • Blackgram is grown purely as a rainfed crop during Kharif and on residual moisture in rice-fallows during rabi.
  • In case there is a long dry spell the crop is benefited if one irrigation is applied, during the winter season, if irrigation facilities are available, one light irrigation at podding/seed filling stage is beneficial to the crop.
  • On the other hand, number and frequency of irrigation depends upon the soil type and weather prevailing during the growth period.
  • Generally the crop should get irrigation at a interval of 10-15 days.
  • From flowering to pod development stage, there is a need of sufficient moisture in the field.
  • Excess water at any stage affects the crop adversely.
