Water conservation in Sugarcane production
Water conservation in Sugarcane production

Water level is constantly falling down all over the world because its consumption has increased almost three times.

These days, about 89 percent of the total water resources are being used in agriculture.

The remaining 6 percent is in domestic and 5 percent is in industrial use.

In such a situation, there can be no other option except saving every drop of water and after cleaning the sea water use it for irrigation purpose in the field.

As comparing to other crops, sugarcane have high moisture content. The final product of sugarcane yield is its weight which contains about 70 percent water.

According to a report, to produce one ton of sugarcane, water equivalent to 200-250 tonnes of weight is required in the form of irrigation.

However, for the condition of moisture in the soil, the amount of water that is suitable to the soil of the root zone of the plant should neither be high nor low, so that there is no tension in the plants.

Generally, sugarcane is a crop of one year duration. It has to undergo many seasons from planting to harvesting.

Generally, reduced availability of irrigation water and lack of moisture in the soil occur in most sugarcane production areas during the period March to June.

Depending on climatic conditions, the water requirement in the production of sugarcane crop is about 1200 to 3500 mm.

After 3-4 months of planting, remove all the dried leaves when the sugarcane is 1.5 m tall and use as a mulch to reduce evaporation. By doing this we can conserve water from soil.

Micro irrigation, especially drip and sprinkler irrigation method has great importance in cultivation. Irrigation with drip method saves water up to 60 percent.

About 40 percent water can be saved by irrigating the crop with sprinkler method till the summer season when the crop is 5-6 months old.
