Multi-species stands of fodder crops within the programme of biologization of agriculture.

摘要

Cultivation of mixed crops (maize + soyabean, maize + faba beans, Sudan grass + soyabean, millet + peas, Sudan grass + mallow [Malva sp.]) was studied in Western Siberia, Russia in 1996-2001. Plots were set up on leached medium loam chernozem. Data on productivity, yield of fodder units and digestible protein are tabulated. Mixed stands with maize had higher productivity when cultivated using the ribbon row system as opposed to interrow cultivation (maize + soyabean 5.54 t fodder units/ha; maize + faba beans 6.94 t fodder units/ha). Sudan grass + soyabean and Sudan grass + mallow mixed crops gave the best results when cultivated using a mixture of seeds (3.68-4.31 and 2.28-4.18 t of fodder units/ha), whereas millet + peas mixed crop was best cultivated using alternating rows (3.18-3.20 t of fodder units/ha).
