Irrigation for sugar cane plantations

Check here for a discussion of sugarcane water requirement.

The work I did with USDA in Texas back in the '70s indicated that the water requirement is pretty well fixed by evaporation and yield requirements. We were able to use saline irrigation water up to a point, but could have lost the high salinity plots had not a very wet rainy period set in during late July. Google "saline irrigation of sugarcane" for the report in the research journal. You may wind up deciding on how much yield reduction is tolerable using a limited water supply. The other alternative is to develop additional water assets by recovering water from the atmosphere using one of several ancient technologies.

Dear Guest,

Thanks for your quick advice.

But, we are not having problem of saline water at all.

The water resources are limited.

Exactly, we are also thinking on the lines of 'rain water harvesting'.

The acceptable yield is 100-110 Ton/ Ha.

ASHOK.
