RESUMO

ABSTRACT: In the Brazilian Central Region, flowering of Paspalum atratum cv. Pojuca is concentrated from mid February to mid March and seed maturation occurs from mid March to mid April, at the onset of the dry season. Use of combine harvesters is an excellent option Pojuca seed production areas because, besides this concentrated flowering and uniform seed maturation, this cultivar presents lon flowering stems which expose the seed heads above the plant canopy. Good agronomical practices regarding choice of the area, tillage, fertilization, seed bed preparation, seeding, weed control will assure the a high seed yield in Pojuca grass. Combine adjustments in the air flow, cutting height, cylinder rotation, and in the threshing and sieving apparatus will reduce losses during the harvesting operation and result in high yields of good quality seeds. At the Embrapa Cerrados Research Center, in well managed Pojuca grass seed production areas, using combine harvesting, pure seed yield ranged from 200 to 300 kg/ha.
