| Popis: | The test chemical Mikrometsen – bis (hydroxymethyl) phosphinic acid (mixture of salts) having high growth regulating and antistress property, in case of twice repeated spraying, reinforced growth of beet tops (number of leaves – 20,7-28,0, control – 17,9 pcs/plant; leaves area – 34,72-38,59 dm2 /plant; biomass of leaves – 188,39-248,32, control -161,74 g/plant) and formation of root crops (length – 29,4-32,3, control – 27,8 cm, diameter – 7,4-8,0, control – 6.9 cm, mass – 438.93-461.24, control – 417.26g). It was also established that with an increase in the consumption rate of the chemical, the absolute values of growth and mass indicators of tops and root crops enhanced. The most powerful leaf rosette and large root crops were formed in the option of treatment of sugar beet plants with the chemical Micrometsen twice (1-st in phase of 4-6 leaves, 2-nd in 20 days after the first) where the consumption rate was 10mg/ha (consumption of working solution – 200 l/ha). In this option, the maximum increase in the yield of root crops was obtained – 12.1%, yield under control – 365.9 centner/ha, sugar yield per hectar – 70.13 centner (control – 58.18 centner). |
