EFFECT OF USING BIO- AND ORGANIC FERTILIZERS ON PRODUCTIVITY AND QUALITY OF CUCUMBER CROP UNDER UAE CONDITIONS

Abstract

This study was carried out during two seasons, 2010 and 2011 in an unheated plastic house at the Ministry of Water and Environmental, experimental farm, northern region in UAE. The main objectives of this study were to investigate the effect of using bio- and organic fertilizers under UAE conditions on plant growth, yield, quality and chemical constituents of cucumber (Cucumis sativus L.) hybrid F1. Queen. A split plot design with three replicates was used and the area of each replicate plot was 4.8m2. The organic fertilizers were arranged in main plots while the bio-organic fertilizers plotted randomly in sub plots. The results can be summarized as follow: 1- It has been found, in the present work that the highest plant height of cucumber were in the plants treated with the compost compared with the rest of organic fertilizers and central control . However, the cucumber plants grown with compost + mycorhizal treatments were superior in plant height compared with any others treatments included in the experiment and control. 2- Regarding the effect of Bio -and organic fertilizers on plant fresh weight significant differences were detected among the plant fresh weight. The compost + mycorhizal gave the highest results than in the others treatments of organic fertilizers. 3- Referring to the effect of Bio-and organic fertilizers on number of leaves per plants, studied had a significant effect on number of leaves / plant the treatments were used as compost + mycorrhizalwere higher than in the at her treatments throughout the experiment.
