Soil Sunburst was applied at the rate of one quart per acre at two treatment levels (single vs. two applications, applied once per cutting) in irrigation water to a first year stand of CUF 101 alfalfa. Treatments were applied in the first irrigation after the previous cutting in May and June 1996. Treatments applied in May increased relative feed value by over 10% compared to the untreated check in the first cutting (June) after application. This increased alfalfa quality rating from fair to good which increased value of hay by approximately $14 /acre. Mean yields between the treatments and untreated plots were similar, although average yields in untreated plots were 50-90 lbs /acre greater than in treated plots. Yields and quality data were not able to be obtained the second harvest (July), not allowing differences, if any, between one and two applications to be determined immediately after the second application. Yields and hay quality values for treatments in the August harvest were almost identical, indicating that treatment effects noted from the May application (and possibly those of the June application) were short term effects, as they did not continue through the August cutting.
