Effect of calcium and some nutrients on pomegranate fruit cracking under Souhag governorate conditions [electronic resource]

Includes bibliographic reference

The present experiment was conducted during 2013 and 2014 seasons, where two pomegranate
cvs. Wardy and Manfalouty were subjected to single and combined applications of ZnS04 (0.3%) as
foliar application, soil application of (CaS04) at 500 g/tree and a mixture of micro elements (zinc,
manganese, iron, cupper, boron, magnesium, sulfur and molybdenum) at 2 g/l were added three times (
first of may, June and July). The selected pomegranate trees aged 9 year old grown in a sand-clay soil
under flood irrigation system and spaced 6 x 5 meters apart in the experimental orchard of
Horticulture Research Station, Shandaweel, Souhag Governorate, Egypt. The aim of the present study
was to examine the effect of these nutrients on reducing fruit cracking and improving yield and fruit
quality of pomegranate grown under Souhag Governorate conditions. Number of fruits/tree,
marketable yield, fruit cracking % and most characteristics of the fruits (physical and chemical) were
higher in cv. Manfalouty relative to Wardy. As a conclusion, subjecting Wardy and Manfalouty
pomegranate cvs. to combined applications of ZnS04 (0.3%) as foliar application, soil application of
(CaS04) at 500 g/tree and a mixture of micro elements as 2 g/l are very effective in controlling fruit
cracking, improving yield and fruit physical and chemical quality grown under Souhag environmental
conditions.
