RT Journal Article SR Electronic A1 Müller, Martin A1 Hrabě, František T1 Effect of owersowing on yields and botanical composition of pasture sward JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 56 IS 4 SP 127 OP 134 DO 10.11118/actaun200856040127 UL https://acta.mendelu.cz/artkey/acu-200804-0014.php AB There are several metods of permanent pasture renovation. Different technologies were investigated on a pasture sward. Three seeders (Einböck seeder with the tine harrow, no-till Sulky disc seeder and SPP 8 strip seeder) and two fertilization regimes (with no fertilization and with mineral fertilization N<sub>90</sub>P<sub>30</sub>K<sub>60</sub> kg.ha<sup>-1</sup>) were used to determine optimum methods of establishment and the use of oversowed pasture swards. In the first year, renovated plots had a higher DM production than control plots. The pasture oversowing had no effect on herbage production in the second production year. The fertilization had no effect in the first production year with a higher clover content in the sward. The share of clovers was higher in plots oversown with the Einböck and Sulky seeders but only in the second and third cuts of the first production year and in the third cut of the second production year. The highest content of clovers was observed in the second and third cuts. There was a positive correlation between the clover content in DM yield and herbage DM production. The oversowing did not show any effect on the grass content in the pasture sward.
