| Abstract | ||
| The present investigation was carried out during the two successive of 2009/2010 and 2010/2011 seasons on Washington Navel orange trees grown at El-Shohada farm, El- Menofeia Governorate of Egypt in order to study the effect of five different harvesting date on the yield, fruit quality and successive yield. In the first season, twenty trees were chosen and divided into 5 groups representing 5 Picking dates (treatments). The picking dates were 15 Dec., 15Jan., 15Feb., l5Mar., and 15Apr., Each treatment was replicated times (four trees), in a randomized complete block design, However, in the second season , another trees were chosen and followed the same procedures as in the first season. The yield as number or weight of fruits / tree was recorded for each tree. The results showed that delaying harvest date from 15Dec. to 15April., total yield as number or weight of fruit / tree has decreased. Moreover, fruit creasing percentage, average fruit weight, fruit diameter, peel thickness, were increased with declaring leanest date, however the fruit juice % was decreased. | ||
