| Abstract | ||||
| This investigation was carried out during 2009 and 2010 seasons on 15 years old seedy guava trees grown in sandy soil of EL-Maamoura region east of Alexandria to evaluate the effect of foliar spray or soil application with mixture of Fe + Mn + Zn in two forms, chelate and sulphate in two rates (1500 and 3000 ppm) on leaf area, leaf total chlorophyll, number of fruits, fruit weight, yield, fruit quality and leaf and fruit mineral contents. The results revealed significant increase of leaf area, leaf total chlorophyll, yield as weight or number of fruits/ tree as well as average fruit weight, length and fruit pulp thickness, TSS %, V.C and total sugars %, reducing and non-reducing sugars comparing with control. The best results associated with the high rate of mixture (Fe + Mn + Zn) 3000 ppm either foliar or soil application in form chelate or sulphate twice annually. | ||||
