Description
The objective of this study was to determine whether plant density would have an influence on dry matter (CM) yield and to determine it’s interaction (if any) with levels of N fertilization. Plants on a broadcast establishment of lovegrass (Eragrostis curvula) were mechanically thinned, to leave 30 cm rows with spacing of 0.5 and 1 m. N fertilizer was applied in spring at levels equivalent to 0, 50, 100 and 150 kg N ha-1. The trial was conducted over three growing seasons. In the second and third years the DM yields with 100 and 150 kg N ha-1 on the broadcast establishment were significantly higher that with other treatment combinations.
