Rp- Types of Soil and their Influence on Grape Production in Al-Ansar District in Salah ul Din Province .pdf

The current study was conducted on grape crop that Al Ansar District in Salah ul Din Province is characterized with. This district is famous in planting and producing grape since long time. The agricultural land devoted to this crop is about 23 thousands dunums which includes seven counties distributed in dispersed was with various agricultural areas that are different among themselves. They also differ in their production as the study clarified. The natural and human geographical factors have remarkable role in producing this crop. The natural factors that were studied are light, temperature, sunrays, humidity, rain, wind, snow, and dust, beside other natural factors relating to soil and water of the physical and chemical side. The most common disease that infect grape and how to treat them were mentioned in the chapters of the study. Concentrations of negative ions included chloride, carbons, bicarbonates, nitrates, phosphates electricity linking, and total melted salt. The positive cations and other positive attributes represented by Calcium, Magnesium, Sodium, ion reciprocal capacity, soil interactive formula, and the organic material. A questionnaire form of the field and recent data were distributed on 280 farmers to calculate and divide data accurately about the grape crop. The laboratory side was very clear through reviewing results. Water and soil samples that were collected from the area of the study were analyzed inside soil and water analysis. The statistical part was very clear through the use of the experimental design method for the first time through which ” the whole random counties” were selected. Beside, other statistical treatments were tackled such as coefficient factors to clarify the relation nature among the study factors. The most important results can be represented by the following:
1. Based soon what was tackled, it was found that planting grape in Iraq belongs very long time. Besides, the nutrition benefit, it was found that it has medical benefit that were discovered through the old engraved materials and recent laboratory analysis.
2. There are two ways for reproducing grape, either layering or shackling which is the most successful where it keeps the origin and quality of the grape.
3. The quantity of falling train, temperature, humidity, dusty storms and sunrays are the most influential nature factors.
4. Soil physical attributes have great role in production quantity as the external density, humidity content, sand, and alluvium.
5. The chemical attributes also have the most prominent role on influencing the crop production and distribution particularly Calcium and Magnesium salt, the organic material, sulfate and melted salts.
6. The irrigation process: farmers irrigate the grape crop with old traditional ways or by the recent dropping way, and this emphasizes the dropping way to protect soil from salting.
7. There should not be overuse of the insecticide since it is a type of poison that lasts long in soil, which causes death of many useful insects, rather, process of spreading insecticide, have to be in modern methods to avoid loss.
