Comparison Effect of Different Kinds and Levels of Organic and mineral fertilization on Some Characteristics of the Grapevine Cultivar, Al-Hulwani


Abstract in English

This research was carried out through the 2012-2013 season on 10 years old, grafted on the rootstock B41,grapevines of Al-Hulwani cultivar. Three levels (10,20,40 t/ha) of organic fertilizers of cow, sheep plus and poultry were used, in addition to three treatments from mixture of this levels (3.33,6.66,13.32 t/ha) for one type of the fertilizers. The research also included three treatments from mixture of mineral fertilization with (N,P,K) at the rate (1:1:1) by using urea 46%, super phosphate 46% and potassium sulphate 50% in three levels (100-200-400 kg/ha), in addition to the control without fertilization, to study their effects on Some quantitative and qualitative Characteristics of the grapevine cultivar Al-Hulwani. The results showed the following: The use of organic and mineral fertilization gave in all levels and types superiority in all studied characteristics compared to the control. Most levels of organic fertilization and its treatments are superior to mineral fertilization in all studied characteristics. The first level of sheep plus (10 kg/ha) gave the better results in weight of cluster and quantity of product, but the first level of poultry gave the better results in weight of 100 fruits. The use of organic manure was with positive effect on fruits color and was superior to mineral fertilization. The yield/vine increased significantly from 65.77kg/vine to 118.5 and 97.8kg/vine when the low level of sheep puls the mixture of the medium levels of mineral fertilizers were used.
