Abstract

This investigation was conducted over two seasons of 2016 and 2017
to elucidate the impact of single and combined applications of wheat seed
sprout at 0.5 to 2% and nano-boron at 0.025 to 0.1 % in fruiting of Superior
grapevines. The selected vines received three sprays at growth start, just after
berry setting and one month later. Carrying out three sprays of wheat seed
sprout at 0.5 to 2 % and/or nano-boron at 0.025 to 0.1% substantially
improved main shoot length, surface area, N, P, K, B, yield, cluster weight and
dimensions, berry weight, while reduced shot berries % and total acidity %
relative to the control treatment. The promotion on growth, yield and berries
quality was in proportional to the increase in concentrations of wheat seed
sprout and nano-boron. A slight effect on these parameters was observed with
increasing concentrations of wheat seed sprout from 1 to 2 % and nano-boron
from 0.05 to 0.1 %. Using wheat seed sprout extract was preferable than using
nano-boron in this respect. Combined application was superior than using each
material alone in this connection. Carrying out three sprays at growth start,
just after berry setting and one month later of a mixture of wheat seed sprout at
1% and nano-boron at 0.05 % was necessary for promoting yield and berries
quality and at the same time reducing shoot berries of Superior grapevines
grown under Minia region.
