Can nitrogen fertiliser applied before sowing increase brassica yields in a dry environment?

D.R. Stevens, A.Y. Carruthers

Abstract

Two experiments compared the effects of five rates (0, 100, 200, 300, and 400 kg urea/ha) of urea (46% N) applied to existing pasture on subsequent establishment and final yields of two direct drilled brassica crops (turnips and kale, and swedes) on different soils in East Otago. Keywords: brassica, fertiliser, kale, nitrogen, swede, turnip
