“…Fertilization especially nitrogen, phosphorus and potassium considered one of the major tools for improvement the soil fertility and increasing the yield for all crops. The beneficial effect of organic and biofertilizers can be attributed to its vital roles for improve soil fertility and amelioration the soil physical and chemical characteristics and which their influence reflected in increment the organic matter, enhancing water holding capacity, soil structure aggregation, and humid substances and reduce soil pH and salinity all these led to may enhance the availability of macro and micronutrients in the soil (Darwish et al, 1995;Simon et al, 1999;Lee et al, 2004Zhang et al, 2010and Asgharzade and Babaeian, 2012.…”

This investigation was conducted during two successive seasons of 2018 & 2019 on Superior seedless grapevines cultivar grown in the experimental farm of faculty of agriculture, South Valley University. Qena Governorate, Egypt, where the soil is sandy loam in attempt to reduce the application of N P K chemical fertilizers through partially substitute of chemical fertilizers with vermicompost and biofertilizers at rate of 25 -75 % to control chemical fertilization and reduce environmental pollution and improve growth, yield and fruit quality of Superior grapevine besides improving the physical and chemical characteristics of the soil. Seven treatments of mineral NPK, vermicompost and biofertilizers were applied to study the impact of them on growth characteristics and fruiting of Superior seedless grapevines as well as soil nutrient status. The results indicated that supplying Superior vine with NPK via mineral sources at 50% plus 860 g vermicompost (approximately 25 % from the recommended dose of NPK) and 150 Ml biofertilizaers (mixed from strains bacteria nitrogen-fixing, Phosphate dissolvers and Silicate dissolver) or 50 % via mineral sources plus 1720 g vermicompost (approximately 50 % from the recommended dose of NPK) was very effective in improving all growth properties, i.e. length of shoot, leaf area, number of leaves /shoot, leaf mineral contents and gave the highest yield and fruit quality of Superior grapevines and improve physical and chemical properties of the soil and reducing environmental pollution. Furthermore, reduction of mineral fertilization may help to produce fruits safe for human as well as decreasing environment pollution.

“…Using the organic and bio-fertilizer as well as Humic acid improve the growth and berry characteristics due to the reliable role of them on enhancing the waterholding capacity, soil structure aggregation, soil organic matter and humid substances may increase the availability of nutrients and reduce soil pH and salinity (Nijjar, 1985;Darwish et al, 1995;Lee et al, 2004Zhang et al, 2010Asgharzade andBabaeian 2012 andSuh et al, 2014). Moreover, they activate the availability uptake and translocation of most nutrients, that accelerating carbohydrate and protein synthesis and nutrient movement, encouraging cell division and development of meristematic tissues.…”

The present investigation was carried out during two successive seasons 2019 and 2020 on Flame seedless grapes cultivar grown in sandy soil at private farm, Naga Hamady, Qena Governorate, Egypt. Eight treatments of mineral N, humic acid, organic and biofertilization applied to study the effect of them on vegetative growth, soil nutrient status, and fruiting of Flame seedless grapevines. The experimental vines were arranged in a complete randomized design with eight treatments and three replications two vine per each. The obtained results could be summarized as follow: Using the recommended dose of nitrogen (RDN) via 25 to 50% mineral plus 25 to 50% Humic acid (HA) or compost and bio-mix significantly increased, leaf area, pruning wood weight, and leaf total chlorophyll as well as leaf nutrient composition compared to use RDN via mineral N fertilizer alone. All combined fertilization treatments significantly increased the yield and improved the cluster and berry traits compared to use RDN via mineral source only. The results of this investigation indicated that, most trace element and soil physical and chemical properties were increased with increasing the level of organic, bio fertilization and humic acid in studied soil. Also, it could be concluded that fertilized vines with 25 to 50% of nitrogen requirements plus HA or compost and bio-mix improved the vegetative growth and nutritional status, as well as, yield, cluster attributes and berry quality of Flame seedless grapevines under this experiment circumstances.

“…Adding HA led to an increase in the vine efficiency and its absorption by the roots, thus amplifying macronutrient concentrations in the leaves [185] and anthocyanin content in the juice (mg/100 g fresh weight) [186]. As indirect effects on Superior Seedless grapevines, HA increased soil microbial population, cation exchange capacity, soil structure, tolerance to salinity stress [187], water-holding capacity, aeration, aggregation, permeability, micronutrient transport, and availability [188].…”

Climate change and disproportionate anthropogenic interventions, such as the excess of phytopharmaceutical products and continuous soil tillage, are jeopardizing viticulture by subjecting plants to continuous abiotic stress. One of the main physiological repercussions of abiotic stress is represented by the unbalanced redox homeostasis due to the overproduction of reactive oxygen species (ROS), ultimately leading to a state of oxidative stress (detrimental to grape quality). To these are added the direct and indirect damages caused by pathogens (biotic stresses). In light of this scenario, it is inevitable that sustainable techniques and sensitivity approaches for environmental and human health have to be applied in viticulture. Sustainable viticulture can only be made with the aid of sustainable products. Biostimulant (PB) applications (including resistance inducers or elicitors) in the vineyard have become interesting maneuvers for counteracting vine diseases and improving grape quality. These also represent a partial alternative to soil fertilization by improving nutrient absorption and avoiding its leaching into the groundwater. Their role as elicitors has important repercussions in the stimulation of the phenylpropanoid pathway by triggering the activation of several enzymes, such as polyphenol oxidase, lipoxygenase, phenylalanine ammonia-lyase, and peroxidase (with the accumulation of phenolic compounds). The present review paper summarizes the PBs’ implications in viticulture, gathering historical, functional, and applicative information. This work aims to highlight the innumerable beneficial effects on vines brought by these products. It also serves to spur the scientific community to a greater contribution in investigating the response mechanisms of the plant to positive inductions.
