Effect of stubble residues on leaf diseases and yield of barley (Hordeum vulgare L. cv. Dampier) were studied by adding small quantities of infested stubble to test plots grown on land where non-barley crop or pasture had been grown in the previous year. Experiments conducted at 5 locations showed that stubble residues increased leaf disease. The severity of leaf disease varied with location and year. Grain yield losses of 9 and 28 percent occurred in the stubble amended plots in 1981 and 1982, respectively. Reductions in number of heads and number of seeds per plot appeared to be the major components of yield loss.
