Caracterização produtiva de espécies de leguminosas forrageiras utilizadas na produção de feno / Productive characterization of species of forage legumes used for hay production

ABSTRACT

The research was conducted to evaluate the production of fodder legumes used in the production of hay. The experiment was conducted in of Federal University of Piaui in Bom Jesus, Piaui. The design was a randomized blocks with six treatments and three replications. Six forage legumes were used Macroptillium lathyroides Access 1, Access 2, Access 3, Stylosanthes capitata, Cajanus cajan, Neonotonia wightti. The variables evaluated were number of plants, green mass of forage production (t ha-1 ) and height. Data were statistically analyzed by Tukey's test at a significance level of 5%. All variables showed differences between the six species of forage legumes (p<0,05). For number of plants per linear meter the S. capitata and N. wightti were higher than 20.00 and 18.00, respectively. The S. capitata and M. lathyroides present better productive characteristics between species.
