Mung bean shoot and root growth under wood ash as a soil acidity neutralizer and fertilizer

ABSTRACT

Eucalyptus wood ash can be a bio-rationale, economically viable, source of fertilizer, to neutralize soil acidy, and contribute to minimizing costs for small farmers who produce mung beans [Vigna radiata (L.) Wilczek] which has a considerable cost of production. The objective was to evaluate the wood ash amendment to the soil and its effects on changing pH and as a fertilizer for mung beans. Amounts of wood ash were 0, 9, 18, 27, 36 or 45 g∙dm⁻³ in the Oxisol. Wood ash can be used as neutralizer and fertilizer, improving the growth of shoots and roots with doses between 21 and 27 g∙dm⁻³.
