Browntop seed production: Past, present and future

Abstract

A survey of 'Grassland Egmont' browntop (Agrostis capillaris syn. A. tenuis) seed yields (1987-1989 incl.) showed a range in production from 0 to over 400 kg/ha, with a relatively low average yield (107-147 kg/ha). In order to elucidate the problems associated with growing Egmont for seed, crops on 23 farms were monitored during the 1989/90 growing season. Trends on yield data were then analysed according to precipitation (rainfall or irrigation) and soil type. Precipitation was found to be the major factor in limiting seed yields. With this information, refinements were developed to present management systems including fertiliser application, weed control, irrigation and harvest and post-harvest management.
