Description

Forage grasses grown for the production of seed are usually components of a crop rotation. The after-effects of 3 grass species compared with 4 crop species on the yields of 5 field crops in the first and second year after grass seed harvest were investigated. Significant differences between the grass species, and between grasses and other field crops on subsequent crops, and between the subsequent crops in their reactions to the preceding crops were obvious in both years after grass seed harvest, Annual and perennial ryegrass excited the most positive effects on subsequent crop yields. Corn and sugarbeets responded particularly well to preceding grass seed crops. Grasses grown for seed increase the water capacity, the content of organic matter and nitrogen in the soil. The infestation of subsequent crops decreased with annual weeds and increased with perennial stoloniferous or rhizomatous weeds.
