Abstract

Plant yield, height, and vigor were increased and chlorosis symptoms were decreased by irrigation and/or mulching of rabbiteye blueberry (Vaccinium ashei Reade). Plant growth ratings were highest in plants receiving both irrigation and mulching. Height, vigor, and survivability of irrigated plants were about twice that of nonirrigated plants. Incorporated organic matter increased height and vigor for nonirrigated and nonmulched plants. Organic matter types and levels resulted in little difference in irrigated plant growth. Incorporated organic matter, mulching, and irrigation all improved the soil moisture condition and enhanced the growth of rabbiteye blueberries.

Joseph, 2009 ). Like many other sources of organic matter, biochars are known to increase retention of water and nutrients in the soil and to improve porosity and permeability of oxygen and other soil gases ( Amoakwah et al., 2017 ; Major et al., 2010

Orge, 2015 ; Sohi et al., 2010 ). Biochar is a high-carbon co-product of pyrolysis of organic matter that differs from charcoal by its intention of application as a soil amendment ( Lehmann, 2007 ). The low density and large surface area of biochar
