“…L EGUMES are important in permanent pastures for high forage yield (2,5,6). Productivity of pastures with shallow soils has been found to be closely associated with past management and legume content 3 • Legumes have been reported to improve animal performance (2,9).…”

Permanent pasture in hill land is frequently on steep and/or rough land unsuited to frequent travel with ground equipment. Ways are needed to introduce and maintain legumes on such land. This study involved 18 treatments using P (208 kg/ha), Mo (2.2 kg/ha), lime (6.5 metric ton/ha), rototilling and white clover, Trifolium repens L. seed (2.2 kg/ha) in various combinations on two permanent pastures in central West Virginia to investigate ways of increasing yields and introducing legumes, and to determine persistence of introduced legumes. A limestone soil (Typic Hapludalf) produced higher yields when treated than a sandstone soil (Typic Dystrochrept) but the reverse was true when no treatments were applied. Legume introduction was more successful on limestone soil than sandstone soil. Phosphorus application was the most critical aspect of treatment on the limestone soil relative to legume introduction and yield increase, whereas liming was the most critical aspect of treatment on the sandstone soil. Legumes on the limestone soil accounted for over 75% of the total forage produced on some plots the year following treatment. Total legume content decreased after the 2nd year and reached a low of near 10% during the 4th year. Volunteer legumes, mostly white clover and red clover (Trifolium pratense L.), accounted for as high a percentage of the total yield as the seeded legume during the 4th and 5th years. On the sandstone soil none of the treatments resulted in enough legumes to account for more than 20% of the forage. Introduction of legumes increased yield and skewed the seasonal distribution pattern toward a higher percentage of total yields early in the season. Molybdenum did not influence legume introduction, yield, or persistence.

“…Days of grazing and average daily gains were also higher with trefoil. Included in good management is adequate fertilization which, as pointed out by Jung, Balasko, and Toben (7), is a must for profitable returns. These workers proposed airplane fertilization of hill pastures to increase production.…”

‘Emerald’ crownvetch (Cornilla varia L.) and ‘Viking’ birdsfoot trefoil (Lotus corniculatus L.) were sod‐seeded into permanent bluegrass pastures. Three types of sod openers were evaluated along with the use of paraquat sprayed in a 15‐cm band over the seeded row to reduce competition from the existing sod. Forage production from these sod‐seeded treatments was compared with complete renovation and seeding to a mixture of orchardgrass (Dactylis glomerata L.), ladino clover (Trifolium repens L.) and red clover (Trifolium pratense L.) and to three rates of nitrogen topdressing on the undisturbed sward. All of the treatments significantly increased forage yields with annual applications of N at 448 kg/ha being the highest. However, such a practice is not economically practical at present. Sod‐seeding with crownvetch was as good as either complete renovation or 140 kg N/ha annually. Sod‐seeded trefoil was less productive but in the third year of the study it was higher yielding than complete renovation. Based on dry matter yields, birdsfoot trefoil and crownvetch offer good possibilities for improving permanent pastures production at minimum cost. These legumes can be seeded and the pasture fertilized in one trip over the field. Crownvetch is especially well suited to this type of seeding because of its spreading growth habit. The disk and disk‐spear openers were generally superior to the spear only. However, with crownvetch the spear plus paraquat was also satisfactory.
