In the dryland areas of southern Australia, summer-active forage crops have been traditionally grown to provide additional home-grown feed during a period when pasture is often in short supply. Dry matter (DM) yields are often variable and the use of nitrogen (N) fertiliser is considered a viable option to increase such yields. The effect of applying N fertiliser to the summer-active species, forage brassica cv. Hunter (Brassica campestris L. × Brassica napus L.), forage brassica cv. Winfred (Brassica napus L.), turnips (Brassica rapa L. cv. Barkant), chicory (Chichorium intybus L. cv. Grouse), plantain (Plantago lanceolata L. cv. Tonic), sorghum sudangrass hybrid cv. Sweet Jumbo [Sorghum bi..View full abstract
