In each of two years, eight 6.48 ha farmlets were used to assess effects of urea applications on dairy production. In the first year, 86 kg N/ha were applied in 2-3 dressings during May-August. Effects on annual milkfat and pasture production were not significant. In the second year 3-4 applications totalling 137 kg N/ha in April to September significantly increased annual milkfat and pasture production. Response in milkfat production per hectare to urea application averaged 0.22 (range - 0.16 to 0.45) and 0.25 (range - 0.1 I to 0.39) kgfat/ kgN in the first and second years respectively. These responses were not economic at present-day prices.
