Resumen
Descripción
The Panicum maximum cv. Mombaça is the most productive tropical grass. For this reason, it is used on intensive production systems submitted to high stocking rate and inputs uses, like nitrogen, irrigation, etc. The nitrogen use implies increases on biomass production due to its effects on morphogenetic plants characteristics. The objective of this work was evaluating morphogenetic and structural responses of mombaça grass receiving 100, 200 or 300 kg ha-1 of nitrogen in form of urea. It was used the randomized block design, with three treatments and four replicates (six paddocks of 0.25 ha each treatment), totaling 4.5 ha.
