The influence of nitrogen fertilization, spring burning and height of stubble on hay and seed production of Eragrostis curvula.

Abstract

This investigation, conducted over a three-year period, emphasized the strong effect of nitrogen fertilization on both hay and seed production. The optimum level of nitrogen, for conditions on the Eastern Highveld being 100-150 kg N/ha applied in spring, followed by subsequent dressings dependent on rainfall. Although the influence of spring burning and stubble height on hay and seed production was not as consistent, both had a strong influence under certain conditions and with more research into their action could become important considerations in management strategies for Eragrostis curvula.Language: English
