Effect of some Soil Amendments on Productivity of Olive Trees in Calcareous Soil

A field experiment was carried out during 2018 and 2019 seasons on Olive trees (Olea europaea L) on orchard located at El Alamein Road, Matruh Governorate, Egypt. In this study, Sulfur and zeolite which was private applied at two equal, the first was done before the season and the second was applied after fruit set at three levels (0, 1000 and 2000 g) for individually or mixing on yield characteristics of manzanelo olive growing under calcareous soil condition. The experiment was carried out a complete randomize block design. The result showed that soil application of (sulphur 1000g/tree + zeolite at 1000g/tree) gave the highest values of number of shoots, average leaf area and chlorophyll content in leaves. Moreover, foliar application sulphur especially at a level of 2000 g / tree zeolite at a level of 2000 g / tree each alone or with each significantly increased the highest values of flowering density, Perfect flower %, fruit set %, fruit length, fruit weight, yield/tree, fruit volume, fruit flesh (%) and fruit oil content (%), In addition, results indicated that sulphur application especially at a level of 2000 g sulphur / tree and zeolite at a concentration of 2000 g / tree each alone or with each other significantly decreased of fruit acidity.
