COMPARAISON DES PRECIPITATIONS PENDANT LA PERIODE DE CULTURE DE SOJA DANS DEUX REGIONS AU BRESIL

Abstract : This paper aims to compare the recent rainfall variability during the soybean cultivation month between 1998-1999 and 2012-2013 in two main producing regions in Brazil: the northwestern Rio Grande do Sul and north Mato Grosso. The data correspond to cumulative monthly figures between October and April of the National Water Agency rain gauge network (ANA) in Brazil. The main results indicate annual variability different modes, especially in subtropical and temperate climates such as Rio Grande do Sul that have the observed rainfall lowest variability values indicating greater consistency between data and also a great relationship with soy annual data. In the Mato Grosso region, dominated by the tropical continental climate and also transitional climate, the variability is lower and the relation between annual rainfall and soybean production cannot be stated as simply.
