The seed yields and limitations to seed production for four tropical grasses cultivars were defined replicated field experiment conducted over years the Cerrados Agricultural Research Centre near Brasilia (15o36'S; longitude 47o42'W) in a tropical savanna region. The four grasses were Brachiaria humidicola, B. decumbens cv. Brasilisk, Panicum maximam var. trichoglume cv. Planaltina. The lighest pure seed yields obtained range from 330 kg ha for A. gayanus cv.Planaltina, to 501 kg for B. humidicola. Observation on flowering behaviour suggestd that Brachiaria species and P. maximum cv. Petrie were day-neutral in their photoperiodic responses. A. gayanus cv. Planaltina had a short-day flowering response. Yields were not limited by diseases or weeds. Under the relatively high soil fertility conditions, undefoliated stands of A. gayanus cv. Planaltina lodged badly in the second season and seed yield was reduced by 65 per cent. In the following year, however, cutting in January prevented lodging significantly increased seed yield. Results indicated that the region is potentially suitable for seed production of all the grasses studied. |
