Transpiration response of upland rice to water deficit changed by different levels of eucalyptus biochar

Abstract: The objective of this work was to evaluate the effect of eucalyptus biochar on the transpiration rate of upland rice 'BRSMG Curinga' as an alternative means to decrease the effect of water stress on plant growth and development. Two-pot experiments were carried out using a completely randomized block design, in a split-plot arrangement, with six replicates. Main plots were water stress (WS) and no-water stress (NWS), and the subplots were biochar doses at 0, 6, 12 and 24% in growing medium (sand). Total transp… Show more

“…The increased water retention provoked by the addition of biochar to the soil, especially in coarse textured soils, like the one studied hereby, was reported by Sohi et al (2010) and Karhu et al (2011). Additionally, Pereira et al (2012) reported that biochar positively affected the amount of plant available soil water. This effect of biochar may also have contributed to its positive effect on yield.…”

“…Additionally, in a pot experiment using a sterile sand, Pereira et al (2012) observed an increase in soil WRC at matric potentials lower than −6 kPa with a rate of 12 % w/w of a similar biochar as the one tested in this study, accompanied by a delay in the point where rice transpiration rate is affected by water stress and declines. Hence, the main objective of this study was to test the impact of a range of wood biochar rates (up to 1.5 % w/w) on both soil WRC and rice yields on a sandy loam Dystric Plinthosol at 2 and 3 years after application under field conditions.…”

“…Beyond the influence that both SSA and particle size of biochar have per se on the soil WRC of a sandy soil, we must also consider the application rate. The maximum rate applied in our study was of 1.5 % w/w, which is half of the minimum rate (3 % w/w) used in other studies that have shown great impact of biochar on soil WRC of sandy soils under artificially controlled conditions (Pereira et al, 2012;Basso et al, 2013). For instance, Basso et al (2013) found a spectacular increase in available water content between −10 and −1500 kPa of 44 and 38 % with application of 3 and 6 % w/w fast pyrolysis red oak biochar, respectively.…”

“…Initially, pot experiments showed significant effects of wood biochar on decreasing acidity and increasing soil nutrient availability of a clay soil and consequently improving aerobic rice growth and biomass production, as shown by Madari et al (2006). Later, Pereira et al (2012) demonstrated the significant effect of wood biochar on increasing the capacity of sand to hold water. In a field trial, Petter et al (2012) also reported positive effects of biochar on soil chemical properties and outstanding positive effects on aerobic rice yields on a sandy loam soil immediately and one year after application.…”
