Effects of nitrogen and irrigation on yield of feed barley
Wocus-type feed barleys showed greatest economical yield response to nitrogen fertilization at rates of up to 140 lbs per acre in the Tulelake Basin. Irrigation before planting and during the tillering stage was necessary for maximum yields. Additional irrigation at the boot stage resulted in increased yields one year and decreased yields another year. Wocus 71, which is 3 to 4 inches shorter in height than Wocus, yielded 8% more grain per acre.
