Abstract:
The response of cv. Muhasan trees and its fruit characteristics to a 50% regulated deficit irrigation (RDI) was studied. The general response to the reduced irrigation was relatively small. However, the schedule of water application was very significant for various fruit characteristics. In the best schedule the 50% reduction in annual irrigation water reduced the oil yield over 4 years by only 12.2% and that of the fruit yield by 18.5%. The most efficient schedule was based on applying all the irrigation water after stone hardening. In lighter soils however, with lower water holding capacity or in regions with a lower rainfall diverting some of the water to the pre-bloom and fruit set period might be needed. The fruit mesocarp/endocarp (flesh/pit) ratio was dependent on the water availability during the stone hardening period. This ratio was significantly improved when water availability during the stone hardening period was reduced. The rate of oil accumulation was also affected by the irrigation schedule but was about the same in 'on' and 'off' years. Fruit growth was less affected by the irrigation schedule but most significantly by the yield load. All the affects of the irrigation schedules were more expressed in the 'on' years than in the 'off' years. No clear cut differences or consistent effects of the irrigation schedule were found on the degree of alternant bearing and mineral content of the leaves. © 2006 Elsevier B.V. All rights reserved.
