Abstract
Maximum the grain yield with minimum expenses is the most challenging factor in the progressing countries like India. Therefore, the main focus of this work was to estimate the wheat yield response to different lateral and dripper spacing combination in drip irrigation system. A field experimentation was organized in the experimental farm of PFDC, College of Agriculture Engineering, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar, to study the “Effect of Dripper Spacing on Yield and Water Productivity of Wheat under Drip Irrigation”. Result found that 23.99% water saves in drip irrigation system contrasted to supervised pipe irrigation. The wheat grain yield was 7.34% and 1000 grain weight was 3.57% more than supervised pipe irrigation. The maximum grain yield was found 46.37 q/ha in 30cm lateral spacing and 30cm dripper spacing. Water productivity of drip irrigated wheat was 19.04% more than the supervised pipe irrigated wheat. The conclusion made with this study was drip irrigation system with 30cm lateral spacing and 50cm dripper spacing shows most suitable result. This combination shows economical result. Thus, drip irrigation system is more efficient with less water than supervised pipe irrigation system.
