3 132nd day 145th day
4 144th day 160th day
5 158th day ...
Stop irrigation after 160th day  
NOTE: i. If irrigation is given on climatological approach, Schedule the irrigation at 0.40 and 0.60 IW/CPE ratio during vegetative and reproductive phases respectively.
ii) The irrigation schedule given above is only a guideline and regulate the irrigation
  depending upon the prevailing weather condition and receipt of rains.
iii) Adopt alternate furrow or skip furrow irrigation to save irrigation water.

The features of the methods are furnished below:
Skip furrow irrigation

  1. Suited to heavy soils like clay and loam
  2. Alternate furrows should be skipped and may be converted to ridges having a wide bed formation.
  3. Short term crops like pulses may be raised in wider bed without exclusive irrigation.
  4. Water saving is 50% when compared to control.

Alternate furrow irrigation

  1. During any one run of irrigation a particular set of alternate furrows is irrigated.
  2. The interval of irrigation should be shortened when compared to the conventional furrows.
  3. During the next run, the left over furrows be irrigated.
  4. Suited to heavy soils like clay and loam.
