Abstract

The response of tomato plants to chemical and bio-fertilization under sandy soil conditions was investigated. The experiments were conducted in Nubaria region, Egypt. Tomato plants were treated with Microbein or a mixture of Phosphorine and Biogein as bio-fertilizers under different rates of the recommended nitrogen and phosphorus fertilization (100% of N and P, 75% of N and P and 50% of N and P). In addition, plants of three treatments received only the rates of chemical fertilizers and were not treated with the bio-fertilizers. Vegetative growth measurements, yield, hormonal changes in leaves, and N, P and K contents of leaves were recorded to study the effects of these treatments. The results showed that bio-fertilization significantly increased the vegetative growth of tomato plants (including plant height, number of branches, number of leaves and the fresh weight of plants) and yield compared to non-treated plants. Growth and yield of tomato plants was negatively affected by the low chemical fertilization treatments especially at 50% of N and P while biofertilization enhanced growth and productivity under such conditions. Tomato plants which were treated with a mixture of Phosphorine and Biogein had higher growth and yield than plants treated with Microbein. Bio-fertilization resulted in higher N, P and K contents of leaves and higher indole acetic acid (IAA), Gibberellins (GA3) and Cytokinins. The possible effects of the treatments are discussed.
