Resumo: A field experiment was carried out on a Dark-Red Latosol Orto at Paranapanema, SP, Brazil, to study the effects of fertilization on soybeans (Glycine max (L.) Merrill), cv. UFV-1, with micronutrients applied or not to the seeds, in two tillage methods: plowing + disking, and subsoiling + disking. The foliar treatments were: 1. control; 2. three applications of 5 l/ha of the formula 5-15-5 at 30, 45 and 60 days from seedling emergence, plus 5 l/ha of the formula 14-4-7 at 75 days from seedling emergence; 3. two applications of 5 l/ha of 5-15-5 plus micronutrients at 45 and 60 days from seedling emergence; 4. two applications of 5 l/ha of 5-15-5 at 45 and 60 days from seedling emergence; 5. idem treatment 4, utilizing 10 l/ha; 6. idem treatment 3, utilizing 10 l/ha. A sub-subplot experimental design was used in all these treatments. An effect of tillage on soybean yield was noticed, which was higher on the plots where the soil was subsoiled and disked. There were not significative effects of micronutrients or foliar fertilization on soybean yields.

Merrill), cv. UFV-1, em dois sistemas de preparo de solo: aração + gradagem, e subsolagem + gradagem. Os tratamentos foliares foram: 1. testemunha; 2. três aplicações de 5 l/ha da fórmula 5-15-5 aos 30, 45 e 60 dias da emergência mais uma aplicação de 5 l/ha da fórmula 14-4-7 aos 75 dias da emergência; 3. duas aplicações de 5 l/ha da fórmula 5-15-5 mais micronutrientes, aos 45 e 60 dias da emergência; 4. duas aplicações de 5 l/ha da fórmula 5-15-5 aos 45 e 60 dias da emergência; 5. idem tratamento 4, com 10 l/ha; 6. idem tratamento 3, com 10 l/ha - todos com delineamento experimental em subsubparcelas. Foi observado efeito significativo sobre a produção da soja quando o solo foi subsolado e gradeado. A aplicação de micronutrientes às sementes apresentou tendência a diminuir a produção. Os adubos aplicados às folhas não causaram diferenças significativas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRosolem, C. A.Silvério, J.
