Abstract
The field experiment was achieved out during successive seasons of 2015 and 2016 on 15 years old, ”Thompson seedless” grapevine grown at a private farm in Gharbia government, Egypt. The vines were planted in loamy clay soil under a surface irrigation system at 1.5meter in row and 3meters between rows. The vines were trained cane under three wires trellis system during January of each experimental season. The tested vines were pruned to 4 canes with 12 eyes each along with 6 renewal spurs. The total bud load was 60 buds. All vines received the same normal cultural practices management as recommended by the Ministry of Agriculture and Land Reclamation for grapevines were done. The vines were well established healthy and uniform as possible in both vigor and crop load. This study was arranged as Factorial experiment in randomized complete block design, since contains Foliar applications of water, Potassium sulfate at 2.5%, Calcium nitrate at 1%, Sitofex at 6ppm (CPPU), and Moringa leaf extract at 2.5% and Moringa leaf extract at 3.5% were used as a spray application either single or in a combination of them on the vine as an attempt to develop growth, cluster and berry quality and enhancement productivity of “Thompson Seedless” grapevine.
