| dc.description.abstract | The effects of three soil materials, three mulching treatments, and two moisture treatments on the growth and forage production of Vernal' alfalfa (Medicago sativa L.) for use in coal mine waste reclamation were studied in a 3 -year experiment in the greenhouse at Tucson, Arizona. The three soil materials were: (1) Gila loam, (2) Unmined soil, and (3) Coal mine soil. The three mulching treatments were: (1) No mulch, (2) Barley (Hordeum vulgare L.) straw, and (3) Russian thistle (Salsola kali L.). The two soil moisture treatments were: (1) Optimum (60 cm total) and (2) Stressed j30 cm total). Significant differences were observed in number of stems per pot, plant height, and forage yield between soil materials, mulching treatments, and soil moisture treatments. The greatest number of stems per pot, the tallest plants, and the highest forage yield were produced in the Gila loam, barley straw mulch, and optimum soil moisture treatment. Use of a soil mulch (incorporated organic matter mulch) produced better plant growth and more forage than when soils were not mulched. Barley straw was a more effective mulching material than was Russian thistle. Within soil materials and within mulching treatments forage yields were significantly higher with optimum soil moisture than they were when moisture was limited. | |
