Abstract:

The experiment has been conducted to evaluate the hydraulic performance of the drippers fitted with drip irrigation system at experimental field of College of Agricultural Engineering under Dr. Rajendra Prasad Central Agricultural University, Pusa in Samastipur district (Bihar), India. The drip irrigation system installed in the field was divided in two parts i.e. left-side and right-side of the sub-main pipeline. Each side has 32 beds of turmeric crop with total number of 64 beds each having a set of two laterals. Each lateral of size 16.0 mm was fitted with 38 number of in-line drippers of inner diameter 13.2 mm and rated discharge capacity of 4.0lph. In present study, four laterals on two beds each side were selected at upper end, middle part and tail end along the sub-main for evaluation of its performance. Results indicated the linearly increasing cumulative pressure head loss along tail end of each lateral. High values of degree of agreement i.e.0.87 between the measured and the estimated dripper’s discharge at mean exponent value of 0.31and coefficient value of (1.48) in discharge-pressure head relationship with power function for drippers installed with the system was observed. The mean statistics of Chi-square test and root mean square error (RMSE) were found to be lowest i.e. 0.13 and 0.07 for left-side drippers and 0.27 and 0.10 for right-side drippers of the sub-main pipeline.
