Abstract:
The performance of drip irrigation in the field under various operating situations is key factor to ensure the required rate of water to all crops during growing periods. A unic characteristics of drip irrigation is the constant application of water and it is regulated by a robust design, management and adoption of the system. Preferably, a well-designed system discharges uniform water to each plant for meeting its needs of water in addition to feasible design and economics. Hence, a field experiment was conducted to study the effect of different levels of irrigation 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 randomized 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 results showed that the maximum plant height (137.5 cm), number of leaves (33), early days to first flowering (76 days), earlier days to 50 percent flowering (92 days), earlier days to first fruiting (109 days), earlier days to 50% fruiting (127 days), highest number of fruits per plant (26), fruit length (42 cm), fruit diameter (9.45 cm), fruit weight (2.20 kg), fruit yield per plant (57.20 kg), fruit yield per unit area (143 t ha^-1) was observed highest in treatment irrigation of 100 percent of CPE and fertigation of 120 percent of RDF (T₉).
