“…This might be due to the increased water availability as well as to resistance of the plants to Fol colonization of xylem vessel in 'GWB comp ' containing soil substrate. Asai et al (2009) andHaider et al (2014) reported an increase in sap flow from xylem and water use efficiency in rice and maize plants, respectively, grown in biochar amended soil. Akhter et al (2015) also suggested that the addition of biochar has positive influence on soil moisture contents which ultimately improves the growth of Fol microconidia inoculated tomato plants.…”

Background and aims Biochars are recognised for their ability to improve soil functions and to stimulate plant defense mechanisms. We evaluated the response of Fusarium oxysporum f. sp. lycopersici chlamydospores to tomato plants grown in biochar and compost amended soil to get a deeper insight into the tomato-Fusarium pathosystem. Methods Wood chips and green waste biochar in combination with compost ('WCB comp and GWB comp ' respectively) were studied for their ability to suppress the Fusarium chlamydospores infectivity. Plant growth parameters and in vitro effects on chlamydospores were determined. Results The 'GWB comp ' soil amendment stimulated plants growth and gaseous exchange rates and had a suppressive effect on the chlamydospore infectivity in comparison with the 'WCB comp ' treatment and the treatment containing compost only. The germination rate of chlamydospores was unaffected by the source of root exudates, whereas the mycelial growth was significantly higher in root exudates from chlamydospore inoculated plants grown in 'WCB comp ' amended soil unlike to 'GWB comp ' amended soil. Conclusion Overall, our findings indicate that both biochars had a variable effect on chlamydospores. We conclude that soil amendment with garden waste biochar and compost exhibit a great potential in suppressing Fusarium chlamydospore infectivity and alleviating pathogen-induced physiological stress in tomato plants.

“…This phenomenon was observed in Scots pine, in which more C was allocated to the roots than to the shoots, which was because of the presence of more N in the roots (Heinonsalo et al, 2015). Most published studies have shown that the BC contains significant amounts of macro-and micronutrients, with the amount depending on the feedstock source, which leads to variation in the extent to which soil nutrient status is improved (Martinsen et al, 2014;Waqas et al, 2014;Zhao et al, 2014;Butnan et al, 2015;Haider et al, 2015). The high amount of these nutrients in BC-amended substrate (Table 1) may be because they were present in the BC (see materials and methods) applied in this experiment and, therefore, had an advantage over the control and only endophyte-treated soils (Zhao et al, 2014;Butnan et al, 2015).…”

“…Other important aspects that make BC a promising candidate for environmentally friendly agriculture are its ability to inhibit methane emission (Gwenzi et al, 2015), remediate heavy metal-contaminated soil, neutralize soil toxic compounds, and increase beneficial microbial activities Li et al, 2015). BC has also been found to reduce the incidence of crop disease and mitigate biotic stress (de Corato et al, 2015;Gwenzi et al, 2015;Haider et al, 2015).…”

Abstract:We studied the effects of hardwood-derived biochar (BC) and the phytohormone-producing endophyte Galactomyces geotrichum WLL1 in soybean (Glycine max (L.) Merr.) with respect to basic, macro-and micronutrient uptakes and assimilations, and their subsequent effects on the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and 1,1-diphenyl-2-picrylhydrazyl (DPPH)-scavenging activity. The assimilation of basic nutrients such as nitrogen was up-regulated, leaving carbon, oxygen, and hydrogen unaffected in BC+G. geotrichum-treated soybean plants. In comparison, the uptakes of macro-and micronutrients fluctuated in the individual or co-application of BC and G. geotrichum in soybean plant organs and rhizospheric substrate. Moreover, the same attribute was recorded for the regulation of functional amino acids, isoflavones, fatty acid composition, total sugar contents, total phenolic contents, and DPPH-scavenging activity. Collectively, these results showed that BC+G. geotrichum-treated soybean yielded better results than did the plants treated with individual applications. It was concluded that BC is an additional nutriment source and that the G. geotrichum acts as a plant biostimulating source and the effects of both are additive towards plant growth promotion. Strategies involving the incorporation of BC and endophytic symbiosis may help achieve eco-friendly agricultural production, thus reducing the excessive use of chemical agents.

“…Although, still little known, biochar can affect the plant physiology. Biochar had an effect on water relations , increasing relative water content and leaf osmotic potential, decreasing stomatal resistance and stimulating foliar (transpiration) gas exchange, and on photosynthesis by increasing the electron transport rate of photosystem II and the relation between effective photochemical quantum yield and non-photochemical quenching (HAIDER, et al, 2015).…”

Growth and production of common bean fertilized with biochar

Production of biochar from organic wastes promises to be an interesting source of plant nutrients, thus reducing pressure on natural resources. To assess the effect of biochar prepared from wastes filtration materials on the growth and production of common bean (Phaseolus vulgaris L.), three simultaneous greenhouse experiments were conducted with three different biochar from organic wastes (rice husk, sawdust, and sorghum silage) using as filtration material for swine biofertilizer. In each experiment the treatments consisted of the addition of five different biochar concentrations (0%, 2.5%, 5%, 7.5%, and 10% v/v), arranged in a completely random design, with four repetitions. Application of biochar increased the root dry mass, shoot dry mass, grain dry mass, number of pods and number of grains. These results indicated that biochar contributed significantly to the growth and production of common bean plants.
