what is night Irrigation?

Night Irrigation 

It refers to the practice of irrigation of crop at night so as to lower the loss of water due to evaporation. Since water is a sparse resource and thus it always remains debatable when to irrigate the crop in a day or at night. Many prefer irrigation at the time of early dawn while others prefer afternoon time. Among all, day time irrigation is the most uneconomical due to high evapotranspitation demand of crop.

In night irrigation, it is ensured that irrigation should complete by the morning before sunrise in order to have sufficient soaking of water by the soil. Water lost during night time irrigation is about 25 – 50% less than that during day time irrigation.
