Sustained Production of Blue Panicgrass, Panicum antidotale Retz., as Influenced by Management Practices

  1. Ethan C. Holt2

Abstract

Abstract

Blue panicgrass, Panicum antidotale Retz., frequently loses vigor following the year of establishment. The effect of cutting height, defoliation frequency, and nitrogen level on sustained production was studied at College Station and Iowa Park, Texas. Delaying harvest later than the boot stage had no advantage in yield in either the current or succeeding year and yield was less with greater stubble heights. Nitrogen increased yields but did not prevent a decline from one year to the next. Yields declined 38% at College Station and 56% at Iowa Park from the first to the second year of treatment. Uniform harvests in the third year indicated slightly favorable effects of some treatment combinations, but no combination prevented a decline in yield.
