Morphogenesis of the giant missionary grass in response to pig slurry fertilization
The morphogenesis of giant missionary grass (Axonopus jesuticus x A. scoparius) was evaluated in this study in response to the application of 0, 40, 80, 120, 160, and 200m³ ha-1year-1 of pig slurry, calculated to provide 0, 100, 200, 300, 400, and 500kg N ha-1year-1, respectively. The experiment was...
