Detailed explanation-1: -Flood irrigation is not the most efficient irrigation method, but it is cheap and low-tech. On the one hand, less water is lost to evaporation than in spray irrigation, but on the other hand, more water can be lost from runoff at the edges of the fields.

Detailed explanation-2: -Surface or flood irrigation is the least efficient manner of irrigation. When a field is flooded, more water than is needed by the plant is applied to the field and water evaporates, seeps into the ground and percolates down to the groundwater, where it can be out of reach of the plant’s roots.

Detailed explanation-3: -There are several irrigation methods on the market, with sprinklers being the most evaporation-prone. Why? These cover a vast amount of ground, projecting water through the air. The evaporation loss is contingent on three factors: time, the climate demand, and the exact surface area of the spray.

Detailed explanation-4: -Furrow (flood) irrigation directs water down crop rows to water plants. This is the least efficient irrigation method for onion production because more water, topsoil, and nutrients are leached and lost in runoff than with drip or sprinkler irrigation.
