Nitrogen availability and glyphosate hormesis on white oat

Most references to glyphosate hormesis refer to changes in morphological characteristics in eucalyptus, soybean, pinus, corn, barley, sugar cane and coffee; nevertheless, effects on crop yield are restricted to a few crops such as barley, beans, Vicia faba and Cicer arietinum (Silva et al., 2012; Brito et al., 2017). [...]far, exploration of the use of herbicides to increase crop yield has been restricted to the use of glyphosate as a ripener in sugar cane (Meschede et al., 2010). [...]hormetic effects were more consistent when the plants were grow under suboptimal conditions, such as low nutrient availability of. [...]beneficial low doses effects of glyphosate can be used to enhance crops yield without increasing the fertilizer use. Low nitrogen stress reduces carbohydrate synthesis and translocation in plants, which reduces glyphosate translocation and efficacy (Mithila et al., 2008). [...]our hypothesis in this study is that low rates of glyphosate stimulate the growth of white oat when nitrogen availability is low. [...]the objective was to evaluate the effects of glyphosate hormesis at different levels of nitrogen on the growth and yield of white oat (Avena sativa L.).
