ALENCAR, Carlos Augusto Brasileiro de et al. Yield of six grasses cultivated under cut management and effect of different irrigation depths and annual seasons. Ciênc. agrotec. [online]. 2009, vol.33, n.5, pp.1307-1313. ISSN 1413-7054.

This study was aimed at evaluating the yield and dry matter content of grasses cultivated under cut management and different annual seasons and irrigation depths. The experiment was carried out in a completely randomized arrangement, with two replications, in a split-split plot design. Six grasses (Xaraes, Mombaça, Tanzania, Pioneiro, Marandu, and Estrela) constituted the plots, six irrigation depths (0%, 18%, 45%, 77%, 100%, and 120% of the control) constituted the split-plots and two seasons (autumn/winter and spring/summer) the split-split-plots. To differentiate the application of irrigation depths the line source sprinkler system was used. The yield and dry matter content were obtained by drying the material in ventilated stoves at 60ºC, for 72 h. The effect of the grasses, annual seasons and irrigation depths were observed for the two characteristics studied. In the autumn/winter season the grasses did not differ and in the spring/summer the Pioneiro presented larger yield. Independently of the season, this same grass presented the smallest dry matter content. The spring/summer season provided larger yield and it did not affect the dry matter content. The irrigation depths increased the yield of the grasses in the autumn/winter season and they did not affect or they decreased the yield in the spring/summer. This same factor reduced the dry matter content of the grasses.

Keywords : Line source sprinkler system; yield; dry matter content.
