Abstract

This investigation was carried out during two successive seasons
of 2007 and 2008 to study the effect of boron and molybdenum foliar
sprays on growth, yield, berry quality and some chemical
constituents of "Superior" grapevine cultivar. The vines were grown
in loamy sand soil. The treatments were (control, B 100 ppm, B 200
ppm, Mo 50 ppm, Mo 100 ppm, B 100 ppm + Mo 50 ppm, B 100
ppm + Mo 100ppm, B 200 ppm + Mo 50 ppm and B 200 ppm + Mo
100 ppm. Generally, it was found that all treatments increased leaf
area, shoot length, cane thickness, cluster weight(g), fresh and dry
weight(g) of 100 berries compared with control. Yield per vine also
increased by all treatments except Mo 50ppm. On the other hand, Mo
treatments reduced total sugars (%) and TSS in berries. Acidity
percentage in fruit juice decreased by foliar spray of boron and
molybdenum. Total Carbohydrates, total chlorophyll, carotenoids, N,
P, K, Fe, Zn and Mn in leaves increased by boron and molybdenum
foliar spray.
