Abstract: RESUMOA utilização de fontes estabilizadas de N, a partir dos mecanismos de inibição da enzima urease e de inibidores da nitrificação do amônio, pode auxiliar na obtenção de maiores tetos produtivos, contribuindo para a sustentabilidade da atividade agrícola. Este trabalho foi conduzido com o objetivo de avaliar o efeito de diferentes fontes e doses de fertilizantes nitrogenados minerais sobre o rendimento de grãos e a eficiência de uso do N pelo milho. Fez-se o experimento no campo, no município de Lages, SC,… Show more

“…Urea has been the most used N fertilizer in maize plantations, due to its cost/ benefit per unit of the nutrient, associated with the agronomic efficiency, and there is a large amplitude of application, from 50 to 200 kg ha -1 (Mota et al, 2015). This study aimed to evaluate the influence of plant architecture (modern and old) of maize hybrids, associated with sowing densities and different levels of top-dressing N fertilization, in the municipalities of Guarapuava (spacing of 0.45 m) and Laranjeiras do Sul (spacing of 0.90 m) in the Paraná state.…”

“…In an experiment with nitrogen rates (0, 70, 140 and 280 kg ha -1 N) in maize, MOTA et al (2015) concluded that the increasing application of nitrogen promotes increased chlorophyll content until the optimal level is reached; however, above the ideal level, there were no differences among rates for the chlorophyll variable. This may indicate that supraoptimal levels of nitrogen are not effective for the extra production of chlorophyll.…”
