The present study was carried out during two successive seasons of 2014 and 2015 on Manfalouty
pomegranate trees grown in a private orchard, situated at Arab-Elawamer region, Abnoub city, Assiut
Government, Egypt. The trees 9-years-old, 'were grown in sandy soil at 5 x Sm apart and irrigated by drip
irrigation system. The main objective of this investigation was to study the effect of dormancy breaking agent
on vegetative growth and flower bud breaking for producing early, high quality and increasing in grain crop
of Manfalouty pomegranate cultivar. Considered dormancy breaking agent were mineral winter oil (MO) and
Hydrogen cyanarnide (H2CN2) (H.C.). Winter oil (MO) was as applied one concentration (3 %), while
hydrogen cyanarnide (H.C.) at three different concentrations (1.5 or 3.0 or 4.5 %) and their combinations. All
treatments were added at as foliar sprays three different dates (1st Jan. or 15 Jan. or 1st Feb.). The aim of this
study was to formulate a general recommendation to be used by pomegranate growers for enhancing
budburst, yield and fruit quality under Assiut govemorate climatic conditions. The results showed significant
variation in the bud burst percentage, fruit yield, fruits weight, fruit grain weight, fruit juice and total
anthothianin percentage in aril and rind. The increase in total soluble solids (TSS) percentage, and Vitamin C
content in fruit juice were obtained by application of winter mineral oil plus Hydrogen cyanarnide (MO 3 % +
H.C. 4.5%) on 1st January. Thus, it can be recommended the application of winter mineral oil plus Hydrogen
cyanarnide (MO 3 % + H.C. 4.5 %) on 1st January which could be a suitable technology for producing early
and high quality of Manfalouty pomegranate fruits under Assiut govemorate climatic conditions. This
treatment is recommended for Manfalouty pomegranate growers in this area.
