The effect of nitrogen on winter pasture production in southern Victoria

Abstract

Winter production of may pastures throughout Victoria is restricted b a shortage of available nitrogen. Field experiments at six sites over three seasons indicated that nitrogen applied to these pastures can markedly 20 increase winter pasture growth. The response at all sites and in all seasons was generally linear, with first order coefficient 0.25. A better response was obtained when nitrogen was applied to pasture 3 inches high than to pasture 1 inch high. Response was independent of date of application.
