Technical Abstract: The addition of cool-season forage legumes to bermudagrass pastures can extend the grazing season and reduce the use of nitrogen fertilizer. The objective was to evaluate the effects of bermudagrass stubble height on clover establishment. Bermudagrass stubble heights at planting significantly (P<0.05) reduced legume ground cover. For every 5 cm increase in stubble height there was nearly a 10% reduction in clover ground cover (2, 84%; 7, 76%; 12, 65%; and 17, 55%; stubble height in cm, percentage ground cover). This reduction was probably due to a lack of good soil-seed contact caused by the inability of seeing equipment to cut through the residue to make proper seed placement. Averaged across years, stubble heights, and cultivars, crimson clover establishment (89%) was better than white clover (51%). Stand regeneration was constant for white clover. Crimson clover stands declined in the regeneration year. In years when soils are saturated for long periods of time during the summer months, it is advisable to lightly seed crimson clover to maintain cover.
