Pure and mixed fodder crop stands for use in Mountainous Altai.

摘要

Data on productivity of fodder crops (mixed and pure stands) in Mountainous Altai, Russia was analysed. The data was gathered in 1983-85. The crops studied were Bromopsis inermis [Bromus inermis], Phleum pratense, Festuca pratensis, Trifolium pratense, Medicago sativa, Onobrychis arenaria and a range of mixed crops combined from the crops above. The best results in the lowland part of Mountainous Altai were achieved using mixed crops T. pratense + B. inermis (4.24 t/ha), T. pratense + F. pratensis (4.14 t/ha) and T. pratense + B. inermis + F. pratensis + M. sativa (4.30 t/ha). The authors state that M. sativa and O. arenaria did not produce high results due to high acidity of the soil in the area studied. The T. pratense + B. inermis + F. pratensis + M. sativa mixed crop also gave the best productivity (6.19 t/ha) when cultivated in the midland area of the Mountainous Altai.
