Sugarcane cultivation areas are usually characterized by low soil fertility and high nutrient demand, especially for nitrogen. Technologies that can raise crop yield and lower the use of pesticides and fertilizers are among the main needs of this crop. The objective of this study was to evaluate the agronomic performance of sugarcane after in-furrow application of the diazotrophic bacterium Nitrospirillum amazonense (BR11145). The treatments consisted of applying five doses of N. amazonense-based product to the planting furrow, 0.25, 0.5, 1.0, 1.5, and 2.0 L commercial product (c.p.) ha-1 ; a treatment consisting of the combination of Bacillus subtilis and Bacillus licheniformis; one control without fertilization; and one control with fertilization. Based on the results obtained from the pooled analysis of two field experiments, the N. amazonense-based product improved the growth parameters of sugarcane plants, and at doses of 1.0 and 1.5 L c.p. ha-1 , these benefits resulted in a significant increase in yield and in the amount of sugar per hectare. Inoculation with diazotrophic bacteria can benefit sugarcane, especially because it promotes the growth and yield of the crop similarly to fertilizers. |

The use of high-quality seeds is a premise for the implantation of pasture under sustainable farming systems to livestock production. The usual practice is to mix Urochloa seeds with nitrogenous to use these inputs. The objective of this study was to evaluate the effect of contact time (0, 3, 6, 12, 24, 48, and 72 hours) and amounts (50, 100, and 150 kg N-1) of urea on Urochloa brizantha seeds physiological quality. A completely randomized experimental design was used, with three replicates. Seedling emergence, germination of normal and abnormal seedlings, and dead seeds were evaluated. It was found that after 3 hours of contact, all seeds lose quality. The number of dead seeds presented a significant (p <0.001) and negative correlation (91.7%) for the number of normal seedlings. The mix ratio between urea and seed affects the seed deterioration index, expressing lower seedlings emerged, concerning control treatment. The highest level of urea (150 kg N-1 ) decreased the emergence index by 23.3% related to the use lowest dose (50 kg N-1). It is concluded that the reduction in viability and vigor begins after 3 hours of contact with fertilizers, so the number of unviable seeds highly increases after 48-hours of contact. |
