| Abstract | ||||
| This study was run out through 2021 and 2022 seasons in a private orchard at Dashlout, Assiut governorate, Egypt to assess the effects of NAA and CPPU on yield and fruit quality of Washington Navel orange trees. The applications were single or together of NAA at 5 to 10 ppm and CPPU at 50 to 100 ppm. NAA and CPPU were sprayed three times, at growth start (first week of March), after fruit setting (first week of May) and at two months later (first week of July). The experiments were arranged in randomized complete block design with three replicates, one tree each. Results showed that, the applications of NAA and CPPU was effective in enhancing yield as well as physical and chemical characteristics of the fruits over control treatment. Using NAA was superior to using CPPU in this respect. Spraying NAA and CPPU together was preferable than using each alone in this connection. Treating Washington Navel orange trees grown under Assiut conditions three times at growth start, just after fruit setting and at two months later with NAA at 10 ppm and CPPU at 100 ppm was responsible for promoting yield and fruit quality. | ||||
