Weed infestation of spring barley (Hordeum vulgare L.) depending on the cover crop and weed control method

1th factor Different cover crop (used as green manure): White mustard, Lacy Phacelia, Legume mix (narro-leaf lupin+field pea), 2nd Factor: Mechanical weed control (flex tine harrow post-emergence), Mechanical and chemical weed control (flex tine harrow + herbicide post-emergence), Chemical (herbicide post-emergence)

Cover crops, mechanical and chemical weed management

Type of stubble crop (Factor 1): conventional tillage without cover crop (several practices has been adopted); cover crop 1; cover crop 2; cover crop 3. Method of weed contorl (Factor 2): mechanical weed control; mechanical and chemical weed control; chemical weed control.

The aim of this 3-year field study was to evaluate the effect of some stubble crops and weed control methods on the species composition, number and air-dry weight of weeds in a spring barley crop grown in short-term monoculture. It included stubble crops which were ploughed under in each year (control treatment without cover crop, white mustard, lacy phacelia, a mixture of legumes - narrow-leaf lupin + field pea) and 3 weed control methods used in spring barley crops (mechanical, mechanical and chemical, chemical weed control).
