New trend to use biochar as foliar application for wheat plants (Triticum Aestivum)

Biochar is a product resulting from pyrolyzing biomass and is rich in carbon and several mineral. Nowadays, biochar is widely applied to agricultural soils as a soil conditioner. This research focuses on using biochar as a foliar fertilizer for wheat plants. The experiment was carried out at Shebin El-kom, El-Menoufia, Egypt, during two successive winter seasons 2015/2016 and 2016/2017 to evaluate the effect of different concentrations of biochar on the plant growth, yield and the nutritive value of wheat plant. Results showed that, the high concentrations of biochar (300mg/L) improved the growth and yield characteristics of wheat. Biochemical constituents as expressed as total sugars, protein, phenols and indoles, as well as free amino acids, and nitrogen varied by growth stage and concentration of biochar. As a result, biochar application can be utilized to enhance the cultivated food crop and decrease the dependence on chemical fertilizers.
