The response of Thompson seedless grape to different levels and times of foliar boron application was studied. The results could be summarized as follows: Average yield and weight of cluster per vine were enhanced by all boron treatments. The highest increase in yield due to boron treatment was 5.9, 11.8, 38.3 and 19.0%, respectively in 1987 season and was 4.4, 17.2, 38.9 and 23.0% in the second season. The effect of the same element on berry weight, size and juice content was similar to that of yield. Boron treatments also increased T.S.S./ acidity and reduced acidity. The best results were obtained when boron was sprayed at 0.5 gm/ liter twice, first before flowering period and again after fruit set.
