| O nitrogênio é um elemento de extrema importância na cultura de forrageiras, sendo o nutriente que mais influencia na produtividade e na qualidade das pastagens. Objetivou-se estudar a condução de uma pastagem com alto potencial produtivo utilizando fontes e doses de nitrogênio. As fontes de N foram nitrato de amônio (N.A.) e ureia aplicadas nas doses de N: 0, 50, 100, 150 e 200 kg ha-1 por corte, na espécie forrageira Panicum maximum cv. Mombaça, avaliando o acúmulo de nitrogênio (N), fósforo (P) e potássio (K) e a taxa de acúmulo de matéria seca (MS). As fontes de N não influenciaram o acúmulo de N, P e K e taxa de acúmulo de MS. As doses influenciaram positivamente no acúmulo de N, K e a taxa de acúmulo de MS, ocorrendo incremento com o aumento das... |

| Nitrogen fertilization in off-season sorghum may have lower cost-benefit ratios than expected due to the residual effect of previous crops. However, the use of growth-promoting bacteria can be an economical alternative to increase crop yields in Cerrado. The objective was to evaluate the response of grain sorghum to nitrogen fertilization and its inoculation by Azospirillum brasilense. This study aims to evaluate grain sorghum responses to nitrogen fertilization and A. brasilense inoculation. The experiment was carried out in a fully randomized block design and 5 x 2 factorial scheme, with five replications. Treatments consisted of applying N recommendation (120 kg N-urea ha-1) split as follows: 100% at sowing, 100% as topdressing, 25% at sowing and 75% as... |

| The objective of this study was to evaluate the viability of pasture with high production capacity and the potential for production of silage using different sources and doses of nitrogen (N) by quantifying the productivity of dry matter (DM), some qualitative characteristics, the total cost of production (TC) and total operating cost (TOC) of silage production. The experimental design was randomized block in a factorial scheme with four replications including two sources of nitrogen (urea and ammonium nitrate) and five N doses (0, 50, 100, 150, and 200 kg ha-1 by cutting). The increase in N provided greater DM and crude protein content and reduced the fiber content in neutral detergent. The source of N did not affect the chemical composition, and... |
