Abstract
During 2005, 2006 and 2007 seasons, three organic N sources: Filter mud (2.5% N), Compost El- Nile (2% N) and Green manure were applied to Superior grapevines as to represent two levels of N i.e 25 or 50g N/vine by using 1.0 or 2.0 kg Filter mud and 1.25 or 2.50kg Compost El- Nile. Organic N sources were added either singly or combined with mineral N source as ammonium Nitrate form (33.3% N). Vine growth and nutritional status as well as berry set, yield per vine and quality of Superior grapes in response to organic materials were investigated.
Application of Green manure, Compost El- Nile and Filter mud aside from mineral N source was in a descending order highly effective in stimulating growth and nutritional status of the vines in addition to improving berry set, increasing yield and number of clusters per vine, cluster weight, berry weight and dimensions and percentage of total soluble solids while decreasing the total acidity of the juice compared to using mineral N source only. A supreme influence was attributed to the application of Green manure plus 75g N/vine in the mineral source on the studied characteristics in comparison with using Filter mud or Compost El- Nile each alone.
The study confirmed the efficiency of Green manure as a good source of organic N fertilizer for Superior grapevines and it was recommended to plough clover in the soil after taking three cuts plus the addition of 75g N/vine in the mineral N source to get the best results with regard to yield and quality of the berries. The beneficial effects of compost on growth and fruiting of Superior grapevines were also confirmed.
