Abstract
The two field trails of present investigation was carried out during 2006 and 2007 seasons on 4-years-old King ruby grapevines grown on clay soil. The trial was to study effect of Orange and Apple wastes compost, in food factories, mixed with farmyard manure to enrich the compost as nitrogen sources complementary for mineral nitrogen on buds behavior, yield and berry quality. The results from this study indicated that applying both kinds of compost either Apple or Orange each alone (40 unit of nitrogen) gave the highest values in bud fertility and fruiting coefficient compared with control that used 40 unit of mineral nitrogen alone, also 40 unit N of OC, 30 unit mineral N +10 units of organic of OC, 40 units organic N of AC and 30 mineral N +10 units organic N of AC recorded in average a pronounce increase on the yield. Application of 40 units organic N of OC gave the highest increase on the berry adherence and firmness during the two seasons of study. All application from organic or mineral fertilizers under study did not show a clear variation in SSC% and acidity in berries juice during the two seasons, application of 10 units organic N from both AC and OC + 30 unit mineral N gave the significant increased in total sugars, reducing sugars and non-reducing sugar in berries juice as compared with control during the two seasons of study. Most interaction between organic and mineral materials gave good values in the anthocyanin content in berry skin in average as compared with control during the two seasons of study. application of 20 unit organic N of both AW and OC +20 unit mineral N gave the lowest values of nitrite and nitrate followed by 40 unit organic N of OC in berries juice compared with control that used 40 unit mineral N alone.
