Increased Crop Yield
The crop yields in the drip irrigation system are higher than the crop yields under irrigation with conventional methods. The water content of the soil varies between field capacity and wilting point in conventional methods of irrigation. Whenever the soil water content is less, the plant has to spend more energy to obtain water. In the drop irrigation system, the soil water content is kept at higher level throughout the crop growth period hence the plant needs to spend less energy compared to the conventional methods of irrigation. Thus the saved energy is useful for productive purposes.
Water with higher Concentration of Salts can be used for Irrigation
In drip irrigation method, the soil water content is kept higher throughout the crop growth period, the irrigation water having more salts can also be used for irrigation through drip system without marked adverse effect on crop growth. In other words, the water that is not suitable through conventional methods of irrigation due to relatively high salinity, can be used for irrigation through drip irrigation without any adverse effect on the crop. However, continuous use of such water will cause salinity hazard.
