Description: Abstract: The objective of this study was to evaluate the effect of nitrogen fertilization on tamani-grass managed under cut. The experiment was carried out in the city of Fortaleza-CE, in the year 2017, in a randomized complete block design. The treatments consisted of increasing doses of 0; 100; 300; 600 and 1,200 kg N ha-1, being the experimental unit plot of 2.5 x 5 m, cultivated with tamani-grass. Leaf elongation rate and stem elongation rate behaved in a linear positive manner, with increments estimated to be 0.00141 and 0.00008643 cm tiller-1 to day-1, making 2.20380 and 3.8958 for the doses of 0 and 1200 kg N ha-1 respectively. The total senescence rate was not significant for the nitrogen doses, presenting 0.38 ± 0.18. The leaf life span responded in a linear negative fashion, with reductions estimated to be 0.00723 days. Nitrogen allowed for higher growth and forage biomass of the tamani-grass, handled under cut, without any increase of senescent material.
