Yield, berry quality and physiological response of grapevine to foliar humic acid application

Abstract: Foliar sprays with humic acid derived from vermicompost at a concentration of 50 ml•L-1 induced a significant increase in the total leaf area, yield and total soluble solids. For several measurements performed in plants we found no significant difference between grapevines treated with HA T2 and those with HA T3. The experimental results in the present study confirm that foliar application with humic acid may improve growth, yield, and berry quality attributes of grapevine.

“…Hence these treatments lead to increase the yield and hasting ripening with good berry quality which lead increase backable yield for exporting. Above mentioned results were in accordance with those obtained by Abdel-Monem et al, (2008) Popescu and Popescu., (2018). They concluded that humic , organic and bio fertilization applied could be improve the growth aspects, yield and fruit quality of different grape cultivars.…”

“…Humic substances include humic acid, humin, and fulvic acid depending on its solvability at various pH (Lee et al, 2004). In this respect, many researchers emphasized the importance of theaforementioned practices to increase the growth and fruiting of grapevines ( Abdel-Monem., 2008;Ferrara and Brunti., 172 2010;El-Sabagh et al, 2011;Abdelaal et al, 2013;Abd El-Kareem 2014;Mohamadiniea et al, 2015;Ibrahim and ali 2016;El-Sally et al, 2017;Akin., 2018 andPopescu andPopescu 2018). Therefore, the objective of this investigation was to study the possibility of using bio-fertilization partially instead of completed mineral fertilizers on growth and fruiting of Flame seedless grapevines.…”

“…The higher RLD in different diameter classes was shown in the compost addition treatments (Tables 4-6). The increase in RLD may be associated with the improvement of biological activities due to the rhizosphere effect, which was characterized by exudation of amino acids and some physiological active substances in the organic fertilizer treatment [40]. In addition, the incorporation of organic compost into soil exerts beneficial effects on root growth by improving the physical and chemical properties in the rhizosphere [41,42].…”

“…Despite the fact that several studies regarding the application of biostimulants in the frame of modulating the nutritional, functional and aromatic profile of berries, musts and wines composition have been conducted (Parrado et al, 2007;Ferrara and Brunetti, 2010;Martínez-Gil et al, 2012Sánchez-Gómez et al, 2016a,b;Frioni et al, 2018;Popescu and Popescu, 2018), the information on the effects of biostimulant application on grapevine morpho-anatomical, biochemical and physiological response mechanisms to counteract biotic/abiotic stresses is still missing.…”
