Book Description
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Book Description
Red clover (Trifolium pratense L.) is one of the many species belonging to the genus Trifolium, which are widely cultivated around the world. It is a perennial plant and offers permanence that determines its uses as well as environmental and agronomic requirements. Red clover is grown mainly for seeds and biomass. The most important environmental factors that affect red clover yield are soil conditions, temperature and precipitation during the growing season. Key agronomic factors include sowing date, cultivation regime, fertilization, plant protection and harvesting date. The species can be grown in pure and mixed stands (with alfalfa, cereals and various grass species). Newly bred triploid varieties of red clover are characterized by desirable growth habit traits and yield components as well as high yield. Red clover has many applications. It is currently experiencing a revival of interest as a traditional folk remedy. The species acts as a rich source of compounds with expectorant, analgesic and antiseptic properties. The callus from Trifolium pratense has been found to exert inhibitory effects on fungal and bacterial strains. Red clover contains isoflavones, anthocyanin pigments and phytoestrogens, which may help reduce the risk of heart disease, breast cancer and endometrial cancer; it also alleviates menopausal symptoms. Red clover lowers blood cholesterol levels and helps prevent prostate cancer. Red clover ointments are used to treat skin diseases, including psoriasis. Red clover provides biomass for livestock nutrition and/or biogas production. It has high nutritional value and constitutes valuable raw material for silage making. Red clover can be grown with grasses, barley, oats and wheat, thus providing various types of fodder with high biological value and natural high-protein feed. When grown as a cover crop, red clover fixes and supplies nitrogen to cereal crops. It also helps break disease and insect cycles, especially in plantations protected against weeds. The crude protein content of red clover decreases with advancing maturity. Due to its permanence, this perennial plant contributes to environmental protection and anesthetization; it helps prevent soil erosion, and is used in phytoremediation and barren land management schemes.

Book Description
Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence production, seed yield and seed yield components for red and white clover seed crops. In each species, five supplemental irrigation treatments were applied in 1990 and 1991 to first and second year seed crops grown on a Woodburn silt loam (fine-silty, mixed, mesic Aquultic Argixeroll) near Corvallis, OR. Non-irrigated controls were also maintained. In red clover, increased plant water stress reduced the duration of the season-long bud and flower production, stem length, potential floral capacity (PFC), and seed yield (SY). Root rot index (RRI) increased with increasing levels of plant water stress, indicating that supplemental water applications reduced second-year root rot severity. The reduction in SY from increasing plant water stress was primarily caused by a decrease in floral fertility, and less conclusively by reductions in inflorescence number per unit area. One irrigation to fill the soil active profile during peak flowering provided adequate water to maintain efficient seed production. In white clover, SY was maximum in 1990 when water application was delayed until 68% of the available soil-water was used by the crop which maintained an even flush of flowers and restricted vegetative growth. In 1991, all irrigation treatments yielded the same or less than the non-watered control. This was due to the excessive vegetative growth from stolons that had grown between the planted rows the previous and present crop year. In both years excessive amounts of irrigation water favored profuse vegetative growth and reduced SY. Inflorescence density was increased by constraining soil-water in 1990 and was the yield component that most affected SY both years. Crop water stress index (CWSI) was a useful indicator of plant stress status and can be used to schedule irrigations in red and white clovers grown for seed under typical climatic conditions of western Oregon.

Book Description
Excerpt from Red Clover Seed and Its Impurities Seeding to clover should follow a cleaning crop that has had deep and thorough cultivation. The suppression of perennial weeds should precede the making of a meadow. Such a location as a clayey hillside, where the soil is apt to become hard after heavy rains, may be greatly improved by a light top-dressing of rotted stable manure. Which should be incorporated with the surface soil by harrowing. Nurse crops are designed, in part at least, for the protection of seedling plants of grasses and clovers. When all the soil moisture does not have to be saved for the meadow, a light nurse crop screens the seedlings from the burning heat of the sun; it helps to suppress weeds until the clover has sufficient vigour to compete with them; and it may give a return from the land while the meadow is developing. Wheat or barley is generally considered most satisfactory as a nurse crop. Oats, even with thin seeding, are later to mature and apt to make too much shade. Standing in a nurse crop, one should be able at any time during the growing season to see the young plants ten or twelve feet away. The nurse crop should be ready to harvest as soon as the clever commences to develop new shoots or branches from the crown.
