Abstract
Experiment was carried out during two successive seasons of 2013/2014 & 2014/2015 It was performed ,proceeded and observed in a private vineyard in Wadi El- Natroon , Beheira governorate, Egypt.
The research reduced the amount of mineral nitrogen fertilizing of the grape (40 unit of N)/feddan .that implemented as 50% mineral and 50% from different resources of organic fertilizers (compost – poultry manure- animal manure) beside different doses of humic acid, which was six ,nine, and twelve litter/feddan .the control was the recommended quantity of superior grape fertilization which is 40%/feddan. The P,K mineral fertilization is fixed. This study measured the quantity ,quality and temporary storability period of superior grape fruits during the cooling transportation to enhance the exportable quantity of yield. The treatments were combined as follows:-
T1 : 100%M.N (control)
T2 : 50% M.N&50% C+6H
T3 : 50% M.N&50% C+9H
T4 : 50% M.N&50% C+12H
T5 : 50% M.N&50% C.M+6H
T6 : 50% M.N&50% C.M+9H
T7 : 50% M.N&50% C.M+12H
T8 : 50% M.N&50% A.M+6H
T9:50% M.N&50% A.M+9H
T10:50% M.N&50% A.M+12H
T11:100% M.N +6H
T12:100% M.N+9H
T13: 100% M.N+12H

Experimental design
The experiment had been designed as Randomized complete block design (RCBD).It was concluded a thirteen treatment. Each treatment had four replicate. The replicate was one Vine (R.Lyman.ott and Michael longnecker, 2010) & (Snedecor and Cochran, 1989).
The grapevines Vitis vinifera Superior Grape cultivar was selected for the experiment as an exportable variety. Vines were six years old which grafted on salt creek rootstock. Vines were transplanted in a sandy loam soil and were spaced at 2X3 meters under drip irrigation system with well water; two drippers were placed for each vine. The EC of water had been 543 ppm. The experiential vines were nearly similar in growth and vigour with Spanish Baron trellising supporting system.The obtained results as follow:
5.1. Effect of organic fertilizers and Humic acid on vegetative growth characteristics.
5.1.1. Wood weight (Kg/vine):
The wood weight of vines which had been treated with 100%M.N (control) (T1)was significantly low in the two season . The highest value was in the vines which treated with 100% M.N+9H (T12) in the two seasons.
5.1.2. Chemical Analysis of leaves
There were increasing in the Nitrogen %, while decreasing in phosphorus % and stability % in potassium leaf content.
5.2. Effect of organic fertilizers n and Humic acid on productivity and quality characteristics at harvest.
5.2.1.Yield and cluster parameters
Total yield (Kg/vine):
The highest value was in the vines which treated with 50% M.N+ 50 A.M % + 12H in the two seasons.
No. of clusters /vine: (cm):
The highest value was in the vines which treated with 50% M.N+ 50 C.M % + 9 or 12 H in the two seasons.
Cluster weight (g):
100% M.N+12H increased the cluster weight in both seasons.
Cluster length (cm):
The highest length in the first season was in the treatment 50% M.N+ 50 C.M % + 6 H while, in the second season was treatment 100% M.N+12 H.
Cluster width (cm):
100% M.N+9 or 12H increased the cluster width in both seasons.
5.2.2.Physical parameters of berries
Berry length (mm):
The highest length in the first season was treatment 50% M.N+ 50 C.M % + 6 H while, in the second season was treatment 50% M.N+ 50 C % + 12
Berry width (cm):
The highest length in the first season was treatment 100% M.N % while, in the second season was treatment 100% M.N % + 12 H
Brush length (cm):
The highest value was in the vines which treated with 50% M.N+ 50 C % + 12 H in the two seasons.
Pedicel length (mm):
The highest value was in the vines which treated with 50% M.N+ 50 A.M % + 9 H in the two seasons.
Pedicel Width (mm):
The highest value was in the vines which treated with 50% M.N+ 50 A.M % + 12 H in the two seasons.
Tours width (mm):
The highest length in the first season was treatment 100% M.N %+ 6 H while, in the second season was treatment 50% M.N+ 50 C.M % + 9 H
Weight of 100 berries (g):
The highest value was in the vines which treated with 100% M.N %+ 12 H in both seasons.
Berry juice %:
The highest value was in the vines which treated with 100% M.N %+ 12 H in both seasons.
5.2.3.Chemical parameters of berries
Total Soluble Solids %( T.S.S) - Brix ◦:
The values were very close with non-significance between treatments.
Titratable Acidity%:
The values were very close with non-significance between treatments.
T.S.S /acid ratios:
In the first season the values were very close with non-significance between treatments, while in the second season 100% M.N %+ 12 H in both seasons was the highest value .
5.3. Effect of organic fertilizers and Humic acid on Postharvest fruit storability
Postharvest parameters
5.3.1.Fruit physical parameters
The highest values of Weight loss , %Shattering berries % , Discarded berries, %Shrinkage berries% and Total loss %and the decresing in the Berry juice % in the 100% M.N % with or without different concentration of humic acid.
5.3.2.Fruit chemical parameters
There were increasing in the TSS and decreasing in the total acidity during the storage period with concern that the highest total acidity was 100% M.N.
In conclusion, the obtained results concluded that, the application of humic acid with 9 and 12 litter with 100 % mineral source of nitrogen increased the pruning wood weight, total yield, weight of cluster, weight of 100 berries, juice percentage and decreased the number of clusters per vine. On the other hand, the application of 50% compost with 12 litter of humic acid increased the berry and brush length which might cause decreasing of shattering berries, while the application of 50% chicken manure with 9 and 12 litter of humic acid increased the pedicel length and weigh.
The postharvest results showed that the storability has been decreased by the using of mineral nitrogen sources for fertilization. 100 % showed high values of weight loss percentage, discarded berries percentage, shattering berries percentage, shrinkage percentage, total loss and the change of T.S.S and acidity. The use of humic acid with 100% mineral fertilization decreased the weight loss. The use of compost and animal manures with 6 and 9 litter of humic acid decreased the shattering percentage.
Sahar, M.A (2007) found that application of organic fertilizer (100% compost) + natural rocks + Effective microorganisms followed by 100% cattle manure + natural rocks + Effective microorganisms of Canino apricot caused a significant increase in fruit storability and shelf life concerning with decreasing decay %, weight loss % and acidity % as well as increasing T.S.S % and Total sugar content compared with inorganic fertilizer.
