Growth and Productivity of Red Globe Grapevines as Affected with Spraying of Fenugreek Seed Sprout, Nano-Boron and Moringa Extract

Abstract

This study tested the effects of fenugreek sprout extract (0.025 -0.1%), Nano boron (0.0025 -0.01%), and Moringa extract (0.05 -0.2%) on vegetative growth, nutritional status of the vine, percentage of berry colouration and sunburned berries, yield, and berry quality of Red Globe grapevines grown under Minia Governorate during 2019 and 2020 seasons. Applications of the extract of fenugreek seed sprouts either alone or in combination with Nano-boron from 0.0025 to 0.01% and Moringa extract from 0.05 to 0.2% significantly promoted all growth traits, yield, weight and dimensions of cluster (length and shoulders), berry weight and dimensions. Moreover, these treatments resulted in better chemical quality of the berries compared with the untreated (control). Percentage of sunburned in the berries materially tended to reduce with the present treatments. The best materials were Nano-boron, fenugreek seed sprout and Moringa extract, in ascending order. However, the best results were obtained when the three ingeredients were combined together. The promotion on these characteristics was related to increase the concentration of each material. Spraying Red Globe grapevines grown under Minia Governorate conditions three times (at the start of growth, immediately after setting, and after one month) with a mixture of fenugreek seed sprout at 0.05%, Nano-boron at 0.005% and Moringa extract at 0.1% was responsible for reducing sunburned % and improving berries colouration % as well as yield and quality of the berries.
