THE EFFECT OF PRUNING ON FRUITING CAPACITY OF MUSCAT BLEU TABLE GRAPE VARIETY IN THE HERZEGOVINA CONDITIONS

Abstract

The study of the effect of various types of pruning on fruiting of Muscat Bleu grape variety in the conditions of Herzegovina lasted for three years. Three pruning variants (28, 32 and 40 buds/vine) were applied in four repetitions. The yield of grapes per vine and the number of clusters per vine was the highest in 2011 year (10.30 kg and 45.98). The yield of grapes per vine (7.59 kg) was the smallest in 2012, and the number of grapes per vine in 2013 (25.93). The total number of productive canes per vine was the highest in 2012 (26.62), and the lowest in 2013 year (total number of productive canes per vine 22.65, number of productive canes per vine 22.47). Pruning variant III had the highest levels of these parameters in all three experimental years, and variant I the lowest.
