Abstract
This study was conducted in a private vineyard at Musaiab / Babylon province on grape cultivar Halwani during the growing seasons of 2001 and 2002 to study the effect of different levels of phosphate fertilization on leaf area /vine and some quantitative and qualitative properties of yield. Phosphate fertilization was dressed on mid- March each season with 5 levels (0,112,225,337,450g P205/vine) using RCBD design in three replicates. Results showed that the application of phosphate fertilization had a significant effect on the leaf area/vine, quantitative and qualitative . Best results were obtained with the level of 225g P205/vine given the highest average leaf area/vine, number of cluster, cluster weight and yield of; 20.06 m2, 56.33cluster/vine, 615.15g and 34.64 kg /vine respectively while they were; 17.68 m2, 52.33 cluster/vine, 541.50g and 28.32kg/vine in control in the second season.Total Soluble Solid (TSS) had insignificantly increased.
