Sesame (Sesamum indicum)

Intercultural operations

  • After cultivation of the crop may be done twice, first at 15 days and the next 25-35 days after sowing.
  • When the plants are about 15 cm in height, thin the crop so as to give a spacing of 15-25 cm between plants.

Irrigation

  • Usually the crop is grown under rainfed conditions.
  • When facilities are available, the crop may be irrigated to field capacity after thinning operation and thereafter at 15-20 days interval.
  • Stop irrigation just before the pods begin to mature.
  • Surface irrigation at 3 cm depth during the critical stages, viz., 4-5 leaves, branching, flowering and pod formation will increase the yield by 35-52 per cent.
  • Two irrigations of 3 cm depth each in the vegetative phase (4-5 leaf stage or branching) and in reproductive phase (at flowering or pod formation) are the best, registering maximum yield and water use efficiency.
  • In the case of single irrigation, it can be best given in the reproductive phase.
  • In the tail end fields in command area, best use of the sparingly available water can be made for augmenting sesame production
