- Abstract
The paper presents the results of field experiments with sugar beet carried out in the period 2017 - 2019 on the fields of PD Devio Nové Sady aimed at researching the influence of different tillage methods on root yield and sugar content. Statistical analysis of the data confirmed a highly significant effect (P < 0.01) of tillage, temperature and precipitations in tested years and their interaction on root yield. Sugar content values were highly influenced by the year and statistically significantly influenced (P < 0.05) by tillage treatments, as well as by the interaction between tillage treatments and the year. The highest average sugar beet root yield was recorded in 2017 (95.9 t ha-1), statistically highly significantly higher than root yields in 2018 (70.9 t ha-1) and in 2019 (72.9 t ha-1). In the overall average of the three studied years, the highest root yield (87 t ha-1) was recorded in Treatment 3 using double disking 120 mm and 200 mm followed by soil loosening to a depth of 340 mm. The observed average was statistically highly significantly higher than other treatments, including the control Treatment 1. The highest average sugar content was achieved in 2019 (16.1%) which is statistically highly significant compared to 2018 (15.1%) and 2017 (14.9%). In the analysis of the overall averages over the evaluated years, the highest average sugar content (15.7%) was recorded in Treatment 4, which used 200 mm disking followed by soil loosening to a depth of 350 mm. This average sugar content in Treatment 4 was significantly higher than control Treatment 1, where disking to depths of 120 and 200 mm was used, followed by plowing to a depth of 250 mm. The application of disking to depths of 120 mm and 200 mm followed by soil chiseling to a depth of 450 mm in Treatment 2 showed the highest variation of the recorded sugar content in the range of 2.26% between the years, while the control treatment sugar content values varied only in the range of 1.34%.
