Abstract

COSTA, Luis Henrique  and  ROSSETTO, Claudia Antonia Vieira. Forage Arachis seeds quality and yield as affected by harvest time. Cienc. Rural [online]. 2008, vol.38, n.8, pp. 2358-2361. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782008000800042.

The aim of this study was to evaluate the forage Arachis seeds (Arachis pintoi) yield and quality as affected by time of harvesting. A completely randomized design with four replications was used. For this were carried out five harvests, starting 12 months after planting (MAP) in December of 2003 and may of 2004, in the Seropédica, RJ. The seeds pods yield, yield components and the germination of seeds with or without pod, were evaluated. The biggest production of seeds pods Arachis pintoi was obtained at 16MAP, when cultivated in December and at 12MAP, in May. The physiological maturity indicators were the weight of 100 seeds and the seeds pods percentage on the soil. The removal of pod associate the alternating temperature contributed for the overcoming of Arachis pintoi seeds dormancy, after four months of storage.

Keywords : Arachis pintoi; germination; dormancy; pods; sowing.
