Where the level of agricultural technology is higher, common bean cultivars with a higher yield potential possibly require greater amounts of micronutrients. In Brazil however, there is a lack of information about the micronutrient extraction and exportation by the main grown cultivars. The objective of this study was to evaluate micronutrient (B, Cu, Fe, Mn, and Zn) extraction and exportation by common bean cultivars Pérola and IAC Alvorada, under different levels of NPK fertilization, on a dystroferric Red Nitosol, in […]

The use of cultivars with a higher yield potential and the adoption of new technology have achieved high grain yields in common bean, which probably changed the demand for nutrients in this crop. However, there is almost no information about the periods of the cycle in which nutrients are most demanded at which quantities by the main cultivars. The objective of this study was to evaluate the macronutrient extraction and exportation by the common bean cultivars Pérola and IAC Alvorada, […]

The determination of nutrient absorption during the growth cycle is essential to determine the periods in which these elements are most required and the correct amounts that should be provided for potato, but for most cultivars used in Brazil the information is extremely scarce. The objective of this study was to evaluate absorption and exportation of the macronutrients N, P, K, Ca, Mg, and S by the potato cultivars Ágata, Asterix, Atlantic, Markies, and Mondial. The experiment was conducted in […]

More productive potato cultivars possibly require larger quantities of micronutrients, but in Brazil there is little information on extraction and exportation of micronutrients by the commonly used potato cultivars. The objective of this study was to evaluate extraction and exportation of micronutrients by the potato cultivars Ágata, Asterix, Atlantic, Markies, and Mondial. The experiment was conducted in Itaí, São Paulo State, Brazil, in the 2008 winter growing season on an Oxisol. Plots consisted of the five potato cultivars and subplots […]
