“…The increase in qualitative parameters is mainly due to increased carbohydrates production during photosynthesis and increased activity of enzymes. These findings were similar that of Shahmaleki et al, (2014) for tomato, Ferrara et al, (2012) for grapes and Yildirim et al, (2006).…”

“…Another example of a biostimulant based on a mixed culture fermentation resulting in microorganisms and their metabolites are variations of the product SoilBuilder. Treatment of plants with SoilBuilder and a different formulation of the same mixed culture fermentation product significantly increased weight of squash (Cucurbita pepo) seedlings with 0, 50, and 100 mM added NaCl (Yildrim 2007). In the same study, treatment with the biostimulants significantly increased weights of transplanted squash plants at the same NaCl concentrations, and at 50 mM NaCl, there was significantly less Na + in leaves of treated plants.…”

“…Applications of some of the tested humic acids as foliar or soil treatments significantly increased total yield, early yield, mean fruit weight, total soluble sugars, reducing sugars, and chlorophyll b content. Similar in-ground greenhouse tests in Turkey evaluated effects of humic acids on tomato (Yildrim 2007). Yield was evaluated by harvesting fruit at the fully-red stage over a three-month period each year.…”

Background Plant biostimulants are diverse substances and microorganisms used to enhance plant growth. The global market for biostimulants is projected to increase 12 % per year and reach over $2,200 million by 2018. Despite the growing use of biostimulants in agriculture, many in the scientific community consider biostimulants to be lacking peer-reviewed scientific evaluation. Scope This article describes the emerging definitions of biostimulants and reviews the literature on five categories of biostimulants: i. microbial inoculants, ii. humic acids, iii. fulvic acids, iv. protein hydrolysates and amino acids, and v. seaweed extracts.Conclusions The large number of publications cited for each category of biostimulants demonstrates that there is growing scientific evidence supporting the use of biostimulants as agricultural inputs on diverse plant species. The cited literature also reveals some commonalities in plant responses to different biostimulants, such as increased root growth, enhanced nutrient uptake, and stress tolerance.

“…Unlu et al (2011) reported a significant effect of foliar-and soilapplied HA on the fruit quality and yield of cucumber in a greenhouse experiment. In addition, some other researchers reported that foliar sprays of humic substances also increase growth, yield, and quality in a number of crop species via increased nutrient uptake (Yildirim, 2007;Karakurt et al, 2009), serving as a source of mineral plant nutrients and regulating their release throughout the growth period (Chen and Aviad, 1990;Atiyeh et al, 2002).…”

IntroductionVegetable crops grown under organic conditions play an important role in the global economy. Hence, some organic substances, such as humic acid (HA) and its salts calcium humate and boron humate, are used for plant cultivation around the world. Humic substances constituting 65%-70% organic matter are used in various areas of agriculture, namely plant physiology and environmental science, because of the multiple roles they play in these areas (Russo and Berlyn, 1990;Türkmen et al., 2004). HAcontaining elements improve soil fertility and increase the availability of nutrient elements by holding them as mineral surfaces (El-Sharkawy and Abdel-Razzak, 2010;Paksoy et al., 2010). The important functional groups of HA include alcoholic hydroxyl, carboxyl, ketone, phenolic hydroxyl, and quinone (Russo and Berlyn, 1990). The mechanism of HA that promotes plant growth is not exactly known, but several explanations have been provided by researchers for increased oxygen uptake, respiration, photosynthesis, cell membrane permeability, phosphate uptake, and root cell elongation (Russo and Berlyn, 1990). Böhme and Lua (1997) stated that HA has important effects on nutrient uptake by plants and is also particularly important for the transport and availability of micronutrients.Studies of the positive effects of HA on plant development have indicated the significance of optimum
