Trickle Irrigation Using Treated Wastewaters

A trickling irrigation system was installed in a cotton field to study the effects on the clogging of the emitters using treated wastewater. Also the effects of using reclaimed effluents on cotton yield and soil properties were studied under the the field conditions. In general the reduction in flow rate in the emitters along the lateral was linear. The changes in soil properties after irrigation with wastewater were found to be within an acceptable range. In response to the given amounts of water, the cotton yield was as expected. This showed that if larger amounts of water were applied under existing irrigation conditions, a higher yield per unit area could be obtained.
