Growth, phenology, water relations and biomass production potential were investigated under clipped and non-clipped conditions. Chloris roxburghiana recorded faster growth rates and greater dry matter fixation than C. ciliaris. This study demonstrated possibilities of fodder production of up to 11 t ha(-1) and 6.6 t ha(-1) for C. roxburghiana and C. ciliaris, respectively. Similarly, C. roxburghiana was more efficient at controlling water loss than C. ciliaris, indicating a better adaptation to drought. On average, growth and leaf area development on clipped plots was faster than the controls. However, defoliation delayed and reduced reproduction. Although defoliation improved the water status of C. roxburghiana, it had no apparent effect on that of C. ciliaris. Growth and green-up responses of C. roxburghiana occurred 2-4 days following rains. The productivity and ecophysiology of these species render them suitable for increasing land productivity in semi-arid areas.
