PHYSIOLOGICAL STUDIES ON GUAVA TREES

Abstract

This investigation was carried out during two successive seasons of 2003 and 2004 on 12 year old seedy guava trees grown at a private farm at Alkhankah region, Qualubeia Governorate. Twenty four trees nearly uniform in their grow vigour and received regularly the same horticultural care adopted annually in the region were carefully selected and devoted for the present study.

This work aimed to improve growth, nutritional status, proquctivity and fruit quality of seedy guava trees through investigating their response to some nutrient element (urea, K2 S04, ZnS04 and Borax); dormex and their possible combinations.
