Time of Sowing

Long-duration varieties:

Sowing at the onset of rains (15 June to 15 July in India) ensures sufficient vegetative growth before flowering.

Short-duration varieties:

Short-duration (140-160 days) varities sown in the first fortnight of June with irrigation or pre- monsoon rains generally results in higher yields.

  • Delayed sowings result in progressive reductions in yield due to early flowering and slow growth.
  • Late sowings may result in poor pod and grain development, due to onset of cool at the pod-filling stage.
  • Advancing sowing of short-duration pigeonpea to April allow timely sowing of wheat. But, this cropping pattern is limited by its requirement for several irrigations.
Extra-short-duration varieties:
These varieties can be sown as late as July in India with only slight reduction in yield. But, these genotypes allow timely sowing of wheat.

Post rainy-season Pigeonpea:
  1. Post-rainy season crop is grown in areas where winters are mild.
  2. September is the optimum time for post- rainy season sowing in peninsular India.
  3. November-sown crop is constrained by extremely slow growth in the vegetative stage, and high temperatures during the reproductive stage. In such situations medium duration varieties have performed well.
  4. Where high temperature stress is not serious, like in Trinidad, West Indies, pigeonpea is sown as late as January.

Late sowing:

  1. Produce less vegetative growth and flower early.
  2. May expose the crop to terminal drought.

Late-duration pigeonpea

In eastern Africa, pigeon peas are sown in October/ November, at the onset of short rains. Being closer to the equator, day length changes in this region are relatively small. Therefore, early flowering is not induced as happens in India and other pigeonpea-growing regions.
