YIELD PLANNING IN TABLE GRAPE PRODUCTION ON STRASHENSKI GRAPE VARIETY

Abstract

Table grape production takes considerable place in the total grape production in Republic of Macedonia. Central Povardarie wine regions, especially Tikvesh wine district has good conditions for producing table grape for consumption in fresh state. Obtaining optimal yield and quality table grape demands aplication of suitable ampelotechnical measures such as: yield planning per vine and hectare, pincage of grape cluster, partial defoliation, and use of biostimulators, use of modern packing centers and use of adequate packing for the table grape. The purpose of the research was yield planning with leaving specific numbers of grape clusters per vine to get high yield and high quality table grape. Three Variants were researched with 18, 23 and 27 grape clusters per vine and Standard with leaving of all grape clusters per vine. Measuring of the yield per vine and per
hectare was conducted, percentage of packed grape and remnants, mechanical analysis of the grape cluster and berry, pressure resistance of the berry, resistance of cluster stem breakage and chemical analysis. The results and information received from the yield per vine and hectare, percentage of packed grapes and remnants, the chemical analysis of sugar content and total acid content are showing that the best results are achieved at the Variant with 27 grape clusters per vine.
