Summary
The objective was to evaluate multiple cropping of small grains harvested as forage and soybean harvested as seed in a dairy forage area. One oat (Avena sativa L.) cultivar, two barley cultivars (Hordeum vulgare L.), and the soybean cv. Hodgson were grown in relay intercropping, double cropping, and sole cropping systems on a Plano silt loam soil at Arlington, WI in 1977 and 1978. Double-cropped soybean was planted after barley and oats were harvested as forage. Early soybean checks (sole cropping) were planted on the same date that relay intercropped soybean was planted, and late soybean checks were planted on the same date that double-cropped soybean was planted. Soybean row widths in all systems were 0.45-, 0.75-, and 0.90-m. Early soybean checks were more productive than soybean relay intercropped in both thinned and unthinned stands of oats and barley, but late soybean checks were not always more productive than double-cropped soybean. Yields of soybean relay intercropped in 0.45-m rows were higher in thinned stands of barley and oats than in unthinned stands. Differences were not as large in wider rows. Cultivar differences in forage yield were not associated with consistent differences in yields of relay intercropped and double-cropped soybean. The most productive cropping sequence was a double-cropping system that had a forage yield of 4.93 Mg/ha and a soybean yield of 2.21 Mg/ha. [AS/Sundar]
