Stapf.  c1984  aThe effects of time of cutting or grazing in the wet season on seed production in the tropical grass Andropogon gayanus var. Bisquamulatus (Hochst.). Stapf. were investigated in two experiments over three seasons. The work was conducted in the tropical savanna region of Brazil at latitude 15o36' S and longitude 47o 42' W. Cutting in mid-January gave the highest seed yields while cutting in mid-March reduced seed yields by 63 percent compared to the uncut control. Tillering was increased by cutting but inflorescence density was unaffected. Cutting reduced the proportion of fertile tillers but did not influence seed size. The highest seed yields under grazing were obtained when animals were excluded in mid-February. The application of the results to seed production practice is discussed briefly.  aBrazil  acutting  agrazing  aAndropogon Gayanus  aCerrado  aPastejo  aPoda  aProdução  aSemente  aBrasil  aSeed production1 aTHOMAS, D.  tJournal of Applied Seed Productiongv.2, p.29-31, 1984.
