Alfalfa living mulch advances biological control of soybean aphid.

Despite evidence for biological control in North America, outbreaks of the invasive soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), continue to occur on soybean (Glycine max L. Merr.).

Species and Nitrogen Effect on Growth Rate, Tiller Density, and Botanical Composition in Grass Hay Production.

Numerous studies have evaluated growth, stand dynamics, and botanical composition of grass swards separately, but little information is available on the interaction of these factors. The objectives of this study were to determine the response of growth rate, tiller density, and botanical composition in orchardgrass (Dactylis glomerata L.), smooth bromegrass (Bromus inermis Leyss.
