Abstrakt
In 2013–2014 field trials were organised in Estonian Crop
Research Institute to comply with the applied project of the Estonian
Ministry of Agriculture. In the establishment of a red clover seed
production field 2 cover crops (barley and spring wheat) were investigated
on 4 treatments and 4 seed rates (2, 4, 6 and 8 kg ha-1
). Based on the field
trials it can be concluded that both two-row barley (the variety 'Maali') and
spring wheat (the variety 'Mooni') are suitable cover crops for the
establishment of a red clover seed production field. For early red clover
barley is more suitable as a cover crop. For the late red clover barley and
spring wheat are equally suitable as cover crops. According to yield results
of cover crop, red clover seed yield as well as economical calculations
based on expenditures, reduction of recommended seed and nitrogen rate
should be decrease to up to 1/3 in spring cereals cultivation. For tetraploid
varieties of red clover we recommend to use 4–6 kg/ha (germination
100%) in the establishment of the red clover seed production field.
