Abstract:
Proper design and operating of drip irrigation system also significantly minimize water use and energy consumption. The poor design of drip irrigation system may leads to under watering many plants and over watering the others rather than distributing water over the whole field. Hence, a field experiment was conducted to study the effect of different levels ofirrigation andfertigation on growth and yield of papaya during the year 2020-21 at Borsi Instructional Farm of Dau Kalyan Singh College of Agriculture and Research Station, IGKV, Bhatapara (C.G.). The experiment was laid out in the rendomized block design with nine treatments combinations and three replications. The experiment comprised of nine treatments under drip method of irrigation with combination of three irrigation regimes viz. 60%, 80% and 100% of cumulative pan evaporation (CPE), three different levels of fertilizer 80%, 100% and 120% of RDF. The average value of the hydraulic performance indicators namely emitter discharge, emission uniformity, distribution efficiency and application efficiency obtained were 1.87 lph, 95.19 percent, 98.07 percent and 93.58 percent, respectively at 1.2 kg cm^-2 operating pressure in 2 lph inline dripper.
