ABSTRACT
The present work study assessed the effect of foliar application of different doses of cobalt (Co) and molybdenum (Mo), and seed inoculation with Bradyrhizobium japonicum on the productive characteristics of the soybean crop and the quality of its seeds. The study was carried out in 2005/06, in a Red-Yellow Latosol (Hapludox) dystrophic soil, in the city of Santa Carmen, MT. The experimental design was a randomized block in a 6 X 2 factorial design, with a combination of 12 treatments with four replications for each treatment. The treatments resulted from the combination of six doses of the product Quimifol CoMo Plus (0.0; 0.25; 0.5; 1.0; 1.5; and 2.0 L ha-1), applied foliarly, with and without inoculation of the seeds with a liquid formulation of Bradyrhizobium japonicum, RizoLiq. Based on the results, the following conclusions were drawn: seed inoculation with Bradyrhizobium increased the number of pods per plant and the number of seeds per plant; the doses of CoMo affected the mass of 100 seeds and the grain yield; inoculation did not result in increases in grain yield; the application of 2 L ha-1 CoMo to inoculated seed improved the seed physiological quality; in the absence of inoculation, increasing doses of CoMo caused decrease in seed physiological quality.
