EFFECT OF ALGAE, AMINO ACIDS AND COMPOST EXTRACT ON THE GROWTH AND PRODUCTIVITY OF FLORIDA PRINCE PEACH TREES

Abstract

This study was carried out during two successive seasons 2014 and 2015 on eight years old peach tress cv. ''Florida prince'' budded on Nemagard rootstock grown in sandy soil of private orchard at El-Sadat region in El-Menoufiya governorate Egypt. This investigation was aimed to study the effect of soil application of organic manure (plant compost, chicken manure) and control and some organic fertilizers as foliar spraying (Algae extract, Amino acids, compost tea) and control on vegetative growth, yield and fruit quality of peach cv. ''Florida prince''. The results indicated that the chicken manure at 100% alone or with foliar spraying by algae extract at100% gave the highest significant values of all vegetative growth parameters including trunk diameter, shoot length, leaf area, and total chlorophyll and leaf mineral contents in both season. Also, this treatment produced the best fruit physical and chemical characteristics.
