| The N and S availability in the early stages of corn development is important that there be no compromising of the crop yield potential. An experiment was carried out in field conditions with the aim to evaluate the effects of nitrogen and sulfated fertilization at maize sowing on nutrition and grain yield, compared to conventional fertilizers and a concentrated formula containing S in its elemental form and also readily available. A randomized block design was adopted with six treatments and four replications. T1, T2, T3 and T4 corresponded to the application 100, 200, 300 and 400 kg ha-1 of the formula 13-33-00 + S 15%, which corresponds, respectively, the following rates NS, kg ha-1: 13-15, 26-30, 39-45 and 52-60. This fertilizer is a granulated mixture... |

| Among the diseases that affect soybeans, white mold stands out as one of the most important currently. Chemical control has been the most effective, given the fast disease evolution and requires farmers’ close attention, primarily in relation to the time of the product being applied, this being one of the most important factors for successful disease control. Thus, this study aimed to evaluate the effectiveness of the control of white mold by applying foliar fungicides in different reproductive stages, by analyzing the progress of the disease in soybean pathosystem versus Sclerotinia sclerotiorum. The experimental area presents a crop rotation system with soybean and cotton being adopted for over 10 years and with a history of occurrence of white mold.... |
