Resumen

MONTANARI, R et al. Relations between the yield of bean (Phaseolus vulgaris L.) and chemical attributes of an Acrustox under no-tillage. J. Soil Sci. Plant Nutr. [online]. 2013, vol.13, n.2, pp.367-379.  Epub 22-Mayo-2013. ISSN 0718-9516.  http://dx.doi.org/10.4067/S0718-95162013005000030.

In crop year 2006/07, in Selvíria, MS, Brazil, were analyzed the productivity of beans because of the chemical attributes of an Acrustox cultivated under conditions of high technological level of management by no-tillage irrigated with pivot central. The objective was to select, among the attributes studied soil, the one with the best representation to explain the variability of agricultural productivity. Geostatistical grid was installed to collect data from soil and plant, with 117 sampling points in an area of 2,025 m2 and homogeneous slope of 0.055 m m-1. From the standpoint of linear and spatial bean yield was respectively explained in terms of P and soil pH. So much for the values of phosphorus (P) in the intermediate layer and subsurface between 24-26 mg dm-3, as well as for Hydrogen (pH) in the surface layer between 5.0 to 5.4, resulted in sites with the most high yield (2,160-2,665 kg ha-1).

Palabras clave : Soil management; no-tillage system; agricultural sustainability; Phaseolus vulgaris L.
