Eradication of Sparseness in the Vineyard and its Influence on the Productivity of Grapes

The most important part of the agro technology of viticulture is providing vine with the planting material, growing vineyards in accordance with modern agro – technological regulations and others. Fighting against sparseness draws special attention among them. Sparseness significantly reduces grape harvest and negatively affects the initial cost of the products produced. Every year certain number of crops is ruined in the vineyard, resulting in the sparseness, which in turn, affects the grape harvest negatively. Moreover, toxic chemicals and the labor provided for the soil cultivation are wasted. We prepared and implemented a scientific research project – “Eradication of Sparseness in the Vineyard and its Influence on the Productivity of Grapes”, which was funded from the budget of Telavi Iakob Gogebashvili State University. The implementation of this project started from October 2021.
The research is carried out on the research plot of Telavi Iakob Gogebashvili State University, in the village of Gulgula, Telavi district, in the agro – ecological area of alluvial soils. There are no irrigation conditions provided on the given plot. The calculations made according to the research methodology at the end of the vegetation showed that the overall growth of the plants planted in sparse areas consisted 15%, i.e. 182
seedlings out of 1211 reached vegetation to the end. Based on the obtained results, the following was decided: the sparse vineyard should be filled by planting the grafted seedlings. The seedlings should be planted in winter or early spring in the deep pre cultivated soil, the fertility of which should be based on the results of laboratory analysis. During the active period of vegetation, the sprouts on newly planted seedlings should be normalized and tied up to an individual support. Plant protection measures should be taken in accordance with climate conditions. The vineyard should be irrigated against droughts.
