Other claims from this paper (14)
- Intervention effect Delay of sowing time did not significantly influence the number of oat plants after germination, except in 2003.
- Association Naked cultivar Akt had lower field germination than hulled cultivar Bajka, depending on vegetation season.
- Intervention effect Two weeks delay of sowing time decreased grain yield significantly.
- Intervention effect Two weeks delay of sowing time slightly decreased the weight of 1000 grains.
- Association Number of panicles per square meter was similar regardless of sowing time.
- Intervention effect Changing sowing depth from the recommended 3 cm decreased grain yield by up to 10%.
- Mechanism The grain yield decrease with changed sowing depth was due to fewer panicles per square meter.
- Observation The yield differences were not similar across sowing time and depth in each year.
- Association Naked cultivar Akt yielded up to 27% less than hulled cultivar Bajka.
- Observation The naked versus hulled yield differences fluctuated from 33 to 24% depending on vegetation season.
- Mechanism The yield difference between naked and hulled oat resulted from lower 1000-grain weight of the naked oat.
- Association Naked oat had lower panicle number per square meter at optimal sowing time.
- Association Naked cultivar had higher grain number per panicle than hulled cultivar Bajka.
- Association Both cultivars tolerated a deeper sowing depth better than a shallower one.
