The effects of September, December and March cuttings of tagasaste (Chamaecyisus palmensis) plants on total edible forage and stem yields and nitrogen concentration and yield were studied in an experiment conducted in New Zealand on a fertile silt loam soil without irrigation or fertilizer. Tagasaste plants of 11 months old (uncut since establishment) were used. Accordingly, September, December, and March cuttings reduced total and stem dry matter yields. Tagasaste plants cut in September, December and March produced the lowest total yield and stem yield while those that were not cut gave the highest total yield and stem yield over 20 months. Total yield of edible forage was not affected by time of cutting. September, December and March cuttings increased the nitrogen concentration of edible forage. Also nitrogen yield was not affected by cutting time. According to the results, tagasaste can be cut every 3 months (in September, December and March) without a significant reduction in total edible forage and nitrogen yields. However, stem production can significantly reduce in edible forage yield of up to 1980 g-2 dry matter can be obtained from dryland tagasaste during the first 20 months of the plant.
