Abstract

This experiment was carried out at the Instituto de Zootecnia, Nova Odessa, State of São Paulo, Brazil, from August/1982 to July/1983, testing six cultivars of Panicum maximum with three fertilization levels. The utilized design was in a randomized blocks with a fatorial scheme of 6 x 3, with three replications, totalizing 54 plots. During twelve monthes, once a month, it was evaluated the height of apical meristem, to know the best management and the tiller€™s number of labeled canopies in order to know the efficiency of regrowth. It was concluded that the low management (15€” 20cm height) is apropriated for the cultivars Hamil, IZ-1, SEA-12 and Red Colonial and the high management (20€” 30 height) for: Wurth and IPEACS. The cultivars that had an increase in their number of tillers with increase of the fertilization€™s levels were: IPEACS, Wurth and SEA-12, all under medium and/or high fertilizations levels. Higher tillers were observed on cultivars Wurth and IZ-1 under medium fertilization and on Red Colonial under high fertilization levels.
