Strip crops of alfalfa and cereal grasses on anthropogenically transformed peat soils

Abstract

On anthropogenically transformed peat soils, strip sowings of alfalfa and a grass mixture of awnless brome, festulolium, perennial ryegrass and timothy with a strip width of 6 m alfalfa + 12 m grass with application of N120P60К120 in three cuttings formed a yield of cereal grasses of 54.6 c/ha and alfalfa 48.7 c/ha of dry weight. With a strip width of 12 m, the grass yield was 22.4% higher than with a width of 6 m. The determination coefficient R² between the yield and the width of the sowing strips for alfalfa was 0.95, and for the cereal grass mixture – 0.69. Strip sowing with a crop placement of 6 m alfalfa + 12 m grass increased the yield of crude protein per hectare by 1.6 times.
