Résumé
This study was carried out during the two successive seasons of 2015 and 2016 on uniform of vigour offshoots and trees of Seewy date palm. This study involved three experiments : First experiment : This study was conducted at New Valley Agric. Res. Station Farm and Directorate of Agriculture in Al-Kharga, New Valley governorate to evaluate the bio-fertilization effects on Seewy offshoots growth. Offshoots of uniform growth and size were carefully separated from mother trees and kept under shade. These offshoots were planted in nursery at February at 2x2 m by 56 offshoots. Each treatment was replicated four times with two offshoots for each replicate. The selected offshoots were subjected to seven fertilization treatments. The treatments contained the following sex bio-fertilizers and control : 1- Using pseudomonas fluorescens (2.5x108 spore/ml). 2- Using yeast (Saccharomyces cervisiae at 4 g/L). 3- Using mycorrhizae (1x103 spore/L). 4- Using humic (4 g/L) acid plus Bacillus megaterium (2.5x108 spore/ml) and B. cereus (2.5x108 spore/ml). 5- Using Azotobacter sp. plus B. megaterium and B. cereus. 6- Using prseudomonas plus B. megaterium and B. cereus. 7- Control (unfertilization). The experimental design was a complete randomized block design with four replicates, two for each.
