Nitrogen is indispensable for pasture establishment, maintenance and production recovery, and its effect is apparently dependent on sulphur supply. It was hypothesized that increasing nitrogen supply requires higher sulphur rates to recover signalgrass (Brachiaria decumbens Stapf.), and that fertilization increases the water use efficiency by plants. The leaf area, dry matter yield, water consumption, and water use efficiency of the grass were evaluated under the application of nitrogen and sulphur rates. Cylinders of 15 cm diameter and 20 cm depth […]
