RATIONALIZATION OF SUGAR BEET PRODUCTION PROCESS BY ALBIT

Field polyfactorial trials realized in years 2013-2014, in warm maize growing region (climatic region: warm; climatic subregion: dry; climatic district: warm, dry, with mild winter and long sunshine, Loam haplic luvisol), monitored the following: impact of the annual weather conditions and foliar application of growth stimulator Albit (control variant, seed disinfecting, single application, double application, triple application) on production parameters (yield of bulbs, sugar content) of sugar beet (variety Predator). Specific course of temperature and moisture conditions confirmed statistically high significant effect of the annual weather conditions on the monitored parameters of sugar beet production not only in the extent of yield of bulbs (65.58 t ha(-1) in 2013, 72.10 t ha(-1) in 2014), but also in sugar content (17.63 % in 2013, 16.30 % in 2014). The highest achieved yields of sugar beet bulbs in the given soil and climatic conditions during the monitored years were statistically non-significant, and were achieved in variant with double application of growth stimulator Albit (69.03 t ha(-1)). Analytically determined sugar content due to treatment (statistically non-significant) was, as well as yield of bulbs, greatly influenced by double application of Albit (17.44 %). The lowest values of both monitored production parameters were found in the control variant.
