Abstract:
The effect of grazing on the above-ground primary production and water use of a fertilised annual pasture and of fertilised sown wheat was studied. Similar studies were made of the effect of cutting on sown wheat. Two simple models-one exponential, the other logistic, both based on the dry weight of the above-ground biomass-were used to describe the primary production in all treatments. The production of undisturbed pasture and undisturbed wheat was 6480 and 7080 kg DM/ha, respectively. Grazing had no significant effect on the total production of the pasture but reduced the DM yield of wheat by up to 32%. Cutting of the wheat reduced the yield by 56%. Water use was similar in all treatments of pasture and wheat and was not directly related to production. The predicted production by both models was similar to observation in the early part of the season but differed from observation in the later part. Possible reasons for the discrepancies are discussed. © 1978.
