Estándares nutricionales foliares para arándano (Vaccinium corymbosum L.) mediante diagnóstico diferencial integrado (DDI), en Chihuahua

Foliar nutritional standards for blueberry (Vaccinium corymbosum L.) by integrated differential diagnosis (DDI), in Chihuahua

Abstract

The blueberry is a plant of recent domestication, in the last years the surface cultivated with this species has increased remarkably as a result of the high demand of the fruit. Cranberry is a plant that is characterized by its high productive life, around 20 years or more with good management and under optimal climate and soil conditions. In some regions of Mexico, the organic and inorganic management of this strawberry has not yet been defined due, among other factors, to the different climatic and edaphic conditions of the producing areas, so it is imperative to carry out preliminary studies in order to propose Rational cultural practices, including fertilization, it is important to generate nutritional standards specific to each region, which supports fertilization. The work was carried out in the municipalities of Cuauhtémoc, Guerrero and Santa Isabel in Chihuahua, during the 2016- 2017 cycles, the foliar sampling was carried out based on the Integrated Differential Diagnosis (DDI) methodology, generating the foliar nutritional standards; each nutrient nine levels were obtained: Deficient (D), Very low (mB), Low (B), Medium low (MB), Sufficient (S), Medium high (MA), High (A), Very high (mA) and Excess (E) in five varieties of blueberry, ‘Biloxi’, ‘Blue King’, ‘Duke’, ‘Elliot’ and ‘Sharpe Blue’. When comparing the standards generated with the state of the art, it was found that K, Ca, Mg, were higher than the state of the art, while Mn and Cu were below; Nt, P, Fe and Zn coincided with the authors reviewed.
