Evaluation of organic fertilization’s effect in the nutritional quality of guinea grass (Paspalum fasciculatum Willd).

Abstract

The effect of an organic chemical fertilizer was evaluated (bovine dung) in some quality indicators of guinea grass (Paspalum fasciculatum Willd). For that research 24 parcels were delimited, 8 by each treatment and a statistical design totally randomized was used, with the following treatments. Three evaluations were made, after 30, 45 and 60 days to analyze the green forage, the dry matter, the crude protein, the neutral detergent fiber, the acid detergent fiber, and the ash. The percentage of MS and FDN were of 22.2 and 50.6 % respectively, in the witness. When the experimental results were observed they showed that the use of 8 t/há of dung allowed registering more height, 100% of aerial cover, better relation leaf-stem, superior values to the ones registered with the rest of the treatments. It was concluded that the addition of organic origin fertilizers used in the grass improves its nutritional content.
