SEED YIELD OF GUINEA GRASS (PANICUM MAXIMUM) AS AFFECTED BY PLANTING METHOD AND SWINE MANURE APPLICATION RATES IN THE NORTHERN GUINEA SAVANA OF NIGERIA

Résumé

The effects of swine manure rates and planting method on the seed yield of Panicum maximum were studied. The design was a 2×4 factorial laid out in a split-plot and replicated 3 times. The treatments were two planting methods (drilling and broadcasting) and four swine manure rates (0, 5, 10 and
15t/ha). Manure rates was the main plot effect while planting method was sub-plot effect. Results show that the seed yield obtained from the grasses planted by the broadcast method was 26% higher (P<0.05) than that recorded for the drilling method. The application of swine manure at 15t/ha
produced higher (P<0.05) yield than other rates of application. This study recommends the application of swine manure at 15t/ha and the use broadcast method for high seed yield of Panicum maximum when propagated by seed.
