Abstract:
The paper describes results of the field experiment with two technologies of oats crop stand establishment. First technology is conventional technology and second is no-tillage technology. The article describes an experiment which was conducted in years 2013–2017. The experiments were located in Nesperská Lhota at Central Bohemia region. Altitude of selected field is 460 m. The experimental field is covered by a light cambi-soil. The differences between the two technologies stand establishment are discussed. Statistical evaluation was performed on both methods in the parameter number of tillers per m2 and yield. Crop yield is the basic indicator of agricultural production and usually affected by quality of soil tillage. One of the parameters affecting the yield is tillage (technology, working tools, depth, turning of soil etc.). Tillage depends mainly on the depth of processing and other quality parameters. An examination of the crop yield is necessary in terms of sensitivity, depending on agro-technical conditions. Among those can be included processing plant soil nutrition and plant protection. It’s always necessary commemorate, in these experiments can’t be excluded some parameters like locality or meteorological parameter influences. Field trial was conceived as multi-year experiment with minimal changes of agro-technical conditions. During the experiment, the positive effect of conventional technology on crop yields was found. This difference was reflected in the number of tillers and in total yield. The measurement shows the beneficial effect of the loosening of soil on the state of the oat crops. The results of experiment show that, the average yield in 5 years observation was 2.11 t ha-1 for no-till technology and 4.22 t ha-1 for conventional technology of tillage.
