Plots of Siratro and Siratro plus Nandi setaria were cut every 4, 8, 12 or 16 weeks at either 7.5cm or 15.0cm above ground over three years. At the end of three years plant density and the residual effect of treatment on yield over ten weeks in spring and summer were measured. The yield of Siratro was reduced by about 30 per cent when grown with setaria (4.04 and 2.86 tha -1 yr -1). But total annual yield was increased at all cutting intervals, by an average of 4t ha-1 when the grass was included (10.6 and 6.6t ha-1 yr -1). Siratro yield increased by an average of 225k ha -1 yr -1 for each week extension of the cutting interval. Associated with this increase was a decline in weed vield and an increase in the percentage of siratro. |
