ABSTRACT
Performance evaluation of tractor operated rain-gun was conducted in research farm, University of Agricultural Sciences, Raichur during 2014-15. A 7.5 hp centrifugal pump was selected for providing prerequisite pressure for operating the raingun. Rain-gun sprinkler was operated by three operating pressure of 3, 4 and 5 kg/cm2 with nozzle size of 14 and 16 mm. water application rate, discharge and radius of coverage was measured with each nozzle at each pressure level. Height of nozzle from ground surface is 1.5 m. The discharge of the raingun varied between 1.9 to 3.8 l/s with 14 to 16 mm nozzles at operating pressure of 3, 4 and 5 kg/cm2. The increase in radius of coverage was proportionate with pressure and nozzle size. Breakeven point and payback period were 109.3 h/annum and 3.6 years, respectively.
Key words :
Discharge, Fuel consumption, Raingun, Sprinkler, Water application rate.
