STUDIES ON REGROWTH RATE IN RELATION TO FODDER YIELD IN CUMBU-NAPIER HYBRIDS

Abstract

Field experiments conducted at the Millet Breeding Station, Tamil Nadu Agricultural University, Coimbatore during 1987 and 1988 with cumbu napier hybrids revealed that none of the hybrids tested was superior to Co-1. The yield components such as-tiller number and regrowth rate decreased towards the maturity of the crop. The regrowth rate and tiller number observed were not related to yield. Competition for nutrients and change in the microclimate may be the possible reasons for such a relationship.

Keywords: Cumbu-Napier (CN), Regrowth rate, Green fodder yield
