“…In contrast, (Mayer et al 2010) found that EM did not increase yield or soil quality in trials conducted over 4 years in Central Europe. Results of a 13 years trial on wheat in China (Hu and Qi, 2013) found that long-term applications of EM significantly increased yield of wheat, grain nutrition, and biomass of straw. Another example of a biostimulant based on a mixed culture fermentation resulting in microorganisms and their metabolites are variations of the product SoilBuilder.…”

“…On example of this category of inoculantbased biostimulants is the product referred to as EM, for "effective microorganisms." As described by Hu and Qi (2013), the inoculant called EM was first described in non-refereed presentations in the early 1900s. The contents of EM were subsequently summarized (Hu and Qi 2013) as containing "about 80 species of microorganisms, which included photosynthetic bacteria, lactic acid bacteria, yeasts, actinomycetes, and fermenting fungi like Aspergillus and Penicillium."…”

Agricultural uses of plant biostimulants

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.

“…Likewise, Reda and Ismail (2008) stated that foliar application with active yeast extract induced significant enhancement the vegetative growth of river red gum plant (Eucalyptus camaldulensis Dehn.). Many studies have found the increase in germination, length and biomass of seedlings after seed treated with yeast strains, enhance plant growth, increase of photosynthesis productivity (Amprayn et al, 2012;Agamy et al, 2013;Hu and Qi 2013). Recently, Kahlel (2015) stated that the addition of bread yeast near the plants roots led to a significant increase in the number of stems, leaf area and fresh and dry weight of the plant compared with the control.…”

A comparison study between the application of gibberellic acid (GA3) and Saccharomyces cerevisiae as a biostimulant on the growth and molecular structures of Eggplant (Solanum melongena L.) has been carried out through a pot experiment. Growth of Solanum melongena L. increased with exogenous application of GA3 followed by yeast. Chlorophyll contents of plant were enhanced with yeast treatment compared with GA3 application and control. Activitiy of antioxidant enzymes, catalase and peroxidase was increased with increasing concentration of GA3 and S. cerevisiae application particularly with using GA3. HPLC analysis showed the highest concentration of salicylic acid in plant treated with GA3 (104.20 mg) followed by S. cerevisiae (70.00 mg) application compared with the untreated plant (57.86 mg). Six common polypeptide bands were observed in treated and untreated S. melongena plants, their molecular weights were 16, 17, 34, 90, 120 and 150 KDa. While the untreated S. melongena plant is characterized by the presence of 8 polypeptide bands, their molecular weights were 19, 24, 32, 33, 36, 50, 109 and 133 KDa. Yeast treatment increased the number of protein bands to 12 instead of 8 in the control plant with molecular weights 18, 125, 74, 69, 62, 31, 30, 27, 25, 23, 20 and 18 KDa. Three polypeptide bands with molecular weights 25, 72 and 125 KDa were detected in S. cerevisiae and GA3 treated plants. PCR analysis showed that total of 16 amplified fragments was visualized in the tested samples. Eight fragments with different molecular weights, four of them are monomorphic bands while the others are polymorphic unique bands. Plant sample sprayed with yeast showed 5 fragments range in molecular weight between 426 to 1766 bp. Only one of these fragments was unique polymorphic fragment. Four monomorphic fragments range in molecular weight from 426 to 1213 bp were showed up in plant sample sprayed with gibberellic acid.

“…Soil inoculation using EM has been employed over a wide range of agro-ecological conditions (Hussain et al 2002), resulting in enhanced crop productivity, improved soil quality and reduced requirement for chemical fertiliser and pesticides (Hussain et al 1999). EM increased the yield of wheat in China (Hu & Qi 2013), seed cotton in Pakistan (Khaliq et al 2006) and onion in New Zealand (Daly & Stewart 1999), nodulation of pea in Pakistan (Javaid 2006), seedling germination and growth of Albizia saman in Bangladesh (Khan et al 2006), and root collar diameter and height growth of black pine in Turkey (Atik 2013). However, there are contradictory effects of EM on crop yields and soil properties.…”

Improvement in soil physical and chemical qualities in a containerised seedling production system is important to manage the survival of seedlings after transplanting and initial growth for reforestation efforts. The effects of mixed ratio of biochar and effective microorganisms (EM) on the growth of Zelkova serrata seedlings were investigated. Five levels of mixed ratio biochar (0-40% v/v with a growth medium) and two levels of fertilisation, either with or without EM, were applied to seedlings for 5 months. Height, root collar diameter and dry weight of each seedling were measured to compare the effects of the treatments. Main effects of the treatments were evident in all parameters. Growth parameters were much higher in seedlings treated with 1 g L -1 fertilisation, EM treatment and low biochar ratio than those treated with 0.5 g L -1 fertilisation, without EM and with high biochar ratio. Quality index was in the order of as 0% > 10%, 20% > 30%, and 40% mixed ratio biochar. Fertilisation and EM treatment increased quality index by 31 and 13% respectively. No significant interactions were found between treatments. These findings indicate that EM with 1 g L -1 fertilisation at low biochar ratio can be applied for better quality of Z. serrata seedlings in a containerised production system.
