Sorghum Nursery Practices

  • Provide one inlet to each nursery unit.
  • Allow water to enter through the inlet and cover all the channels till the raised beds are wet and then cut off water and
  • Adjust the frequency of irrigation according to the soil types as follows:
Number of irrigationsRed soilsHeavy soils
First irrigationImmediately after sowingImmediately after sowing
Second irrigation3rd day after sowing4th day after sowing
Third irrigation7th day after sowing9th day after sowing
Fourth irrigation12th day after sowing16th day after sowing

NOTE: Do not allow cracks to develop in the nursery by properly adjusting the quantity of irrigation water.

Main field Preparation for Irrigated Crop

Formation of Ridges and Furrows

  • Form ridges and furrows using a ridger at 6 m long and 45 cm apart
  • Form irrigation channels across the furrows
  • Alternatively, form beds of size 10 m2 and 20 m2 depending on the availability of water.

Forming ridges and furrows

Main Field Regulate irrigation according to the following growth phase of the crop.

Maturity phase (Control irrigation)

NOTE : Adjust irrigation schedule according to the weather conditions and depending upon the receipt of rains.

Contingent Plan:

  1. This should be done before 75% of soil moisture is lost from available water.
  2. Spraying 3% Kaolin (30 g in one litre of water) during periods of stress will mitigate the ill effects.

Ratoon Sorghum Crop

Water Management

  • Irrigate immediately after cutting the main crop.
  • Irrigation should not be delayed for more than 24 hours after cutting.
  • Irrigate on 3rd or 4th day after cutting.
  • Subsequently irrigate once in 7 - 10 days.
  • Stop irrigation on 70 - 80 days after ratooning.
