Vliv různého zpracování půdy na výnosy a ekonomiku pěstování kukuřice na zrno

The thesis was evaluated the effect of different tillage on yield and economics of maize grain. Monitoring was carried out in the years 2006 - 2012 on loamy gley Fluvisol in corn production areas. Corn for grain was within the crop rotation grown after winter wheat. Comparison of two variants of tillage: 1) Conventional tillage with plowing (0.22 meters) 2) Minimization tillage with shallow loosening (at 0.15 m) Effects of different tillage on yields of corn for grain was lackluster, the differences between the versions in addition to the 2010 statistically inconclusive. Higher average yield for the reference years were recorded on the variant of the classical tillage (10.65 t /ha), lower average yield was at variant with shallow tillage (10.34 t /ha). The difference in yield between the variants was 0.31 tons per hectare. Sales of a conventional tillage were on average higher years (46,627 Kč/ha) as compared to minimization processing (46,297 Kč/ha), the difference between the variants was 330 Kč per hectare. Direct costs were a conventional tillage on average in higher (18 094 Kč/ha) than in the minimization process (17 470 Kč/ha), the difference between the variants was 624 Kč per hectare. Contribution margin was a conventional tillage on average in lower (29 295 Kč/ha) than in the minimization process (29 573 Kč/ha), the difference between the variants was 278 Kč per hectare. The results show the overall monitoring of the environmental conditions of the possibility of using both technological procedures tillage (classical and minimization) of maize grain grown in crop rotation after winter wheat
