Sugarcane Irrigation in Pakistan

Center Pivot Irrigation System is most common in all over the world but in Pakistan it is introduced from few years. Center pivot irrigation systems are now introduced on large farms of country.

Sugar cane is a perennial crop and water requirements on an average varies from 47 – 63 inches for the spring crop and 80 – 98 inches for the autumn crop depending upon season, the fertility of soil, and the variety of cane. Autumn planting requires a higher quantity of water than spring planting. During the dry period, sufficient water should be applied at relatively short intervals to avoid moisture stress. When crop shows wilting it means big loss has been occurred for this to avoid from water stress.

Irrigation Schedule

The goal of an efficient irrigation scheduling program is to "provide knowledge on correct time and optimum quantity of water application to optimize crop yields with maximum water use efficiency and at the same time ensure minimum damage to the soil". Thus,

  • Irrigation scheduling is the decision of when and how much water to apply to a cropped field.
  • Its purpose is to maximize irrigation efficiency by applying the exact amount of water needed to replenish the soil moisture to the desired level.
  • Make efficient use of water and energy.

Sugarcane crop should not be over irrigated because it leads to wastage of water, loss of Nitrogen by deep percolation serious deterioration of soil from water logging and salinity. It is very important to take care of the irrigation requirements of sugarcane, particularly in summer months. Farmers must plan their acreage to be planted under cane crop according to the available water at their farm. The aim of sugar cane grower should be to get high yields year after without imparting soil productivity.
