Influence of fertilizer source and rate on soybean varieties

The objective was to evaluate the yield of three soybean (Glycine max) varieties, each one growing in different year, using three fertilizer (Fosmag, 00-17-17, Yorin + KCl, ARAD + KCl, 02-27-20) rates: recommended, low and control. To conduct the experiment on Maracaju municipal district, Mato Grosso do Sul state Brazil, in an Oxisol, a randomized block design with five repetitions and eleven treatments (ten treatments + control) was used. The application of Fosmag and 00-17-17 formulation showed to be the best fertilizer to three varieties under experimental soil conditions.
