Emission uniformity evaluation of installed drip irrigation system

Abstract

The main function of drip irrigation is to meet consumptive water use requirements of a crop within certain hydraulic and uniformity conditions. The emission uniformity distribution in drip irrigation systems is important in irrigation water management and could serve as the basis for optimizing water use efficiency and crop productivity. The water distribution uniformity was then evaluated using the method – EU field test. The experiment was conducted at Hi-Tech Horticulture of RAU, Pusa, Bihar. General rating for uniformity are 90% or greater 80% to90%, 70 to 80% and for Less than 70% - Excellent, good, fair and Poor respectively. The absolute emission uniformity was found 95.14% in the drip irrigation system under polyhouse. Hence the drip irrigation system in water distribution uniformity is excellent. Hence the drip irrigation system in water distribution uniformity is excellent. The emission uniformity distribution in drip irrigation systems is important in irrigation water management and it serve as the basis for optimizing water use efficiency and crop productivity.
