A.  aEfecto de la frecuencia de cortes en la produccion de semillas de Arachis pintoi.  c1998  aThe effect of successive cuttings and their combinations on the seed production of Arachis pintoi BRA-031143 was evaluated at the Cerrado Agricultural Research Center (EMBRAPA-CPAC, its Portuguese acronym) in Planaltina (DF, Brazil) located at 15o35'30" S and 47o42'30" W, at 1000 m.a.s.l. Experimental treatments consisted of cutting at 3-month intervals, from planting to 9 months after planting, at all possible combinations: T1= check, absence of cutting; T2= cutting every 3 months after planting; T3 = cutting at 3 and 6 months after planting; T4 = cutting at 3, 6, and 9 months after planting; T5 = cutting at 3 and 9 months after planting; T6 = cutting at 6 months after planting; T7 = cutting at 9 months after planting; and T8= cutting at 6 and 9 months after planting. Cuttings were done manually, and the forage was removed from the area. Pure seed production over the 12-month period was evaluated in plots 0.5 m long x 0.5 m wide x 0.2 m deep (0.05 m3). Treatment T8 which corresponded to cuttings in March (6 months after planting) and july (9 months after planting), shouwed that it is possible to produce A. pintoi seed white also taking advantage of its forage for animal nutrition. In the cerrados ecosystem, these months coincide with the most critical periods of water and forage deficits.  aArachis pintoi  aCerrado  aPlanta Forrageira  aSemente  aFeed crops  aSeed1 aCARVALHO, M.
