CRUZ-BARRON, Vania et al. Extraction and macronutrient requirements in 'Ataulfo' mango (Mangifera indica L.) with management of annual and biennial pruning. Rev. Mex. Cienc. Agríc [online]. 2014, vol.5, n.2, pp.229-239. ISSN 2007-0934.

For determining, the nutritional requirement in mango 'Ataulfo' is essential for the comprehensive management of fertilization. The objective of this research was to determine the extraction and macronutrient requirements from the concentration of N, P, K, Ca and Mg in biomass pruned and fruit produced in growing 'Ataulfo' mango orchards managed with annual pruning biannually. The pruning treatments were annual and biannual pruning. Annual pruning is done in August 2007, 2008 and 2009 while the biannual pruning was performed in August 2007 and August 2009. The results indicated that, the pruned biomass differ significantly between treatments. Annually pruned trees produced 18.2 kg of dry matter while those pruned biannually accumulated 31.87 kg. To calculate the demand for performance-macronutrient, we propose the following factors in kg nutrient per ton of harvested fruit: N, 4.19, P, 0.79, K 7.19, Ca 3.67, and Mg, 0.93.
