PRODUCTIVITY AND QUALITY OF SUGAR BEET AS INFLUENCED BY NITROGEN FERTILIZER AND SOME MICRONUTRIENTS

Ryazan region annually receives stable yields of sugar beet roots 40 t/ha. Further growth of yields depends on balanced nutrition of plants cultivated hybrids, from the quality of the soil and of the phytosanitary State of sowing culture. Weed vegetation in wider spaced row crops of sugar beet in the initial periods of vegetation is high competition culture. The article presents the results of three studies on the effectiveness of the herbicide betanalnoj group, used to reduce contamination of sowing culture annual dicotyledonous weeds and increase the harvest of sugar beet roots. Studies conducted on experimental fields ISSA-branch FGBNU FNAC WIM (former AGRICULTURAL RESEARCH INSTITUTE in Ryazan). Soil: dark grey forest tjazhelosuglinistaja, humus content 4.0%, potassium and phosphorus-high pH is 5.8. Area of cultivated plots 50 m2, repetition, four sugar beet variety-Ocean. The predecessor-winter wheat. Under the autumn ploughing had made NPK120 under presowing cultivation-N60, SEV conducted seeder sowing machine. For crop protection herbicides were tested annually of sugar beet Betanal progress, UF-1.0 l/HA, Forte di Belvedere-1.0 l/HA, Betanal Max Pro-1.5 l/HA, Bajrang engineering works Super-1.5 l/HA, once applied to weeds. The harvest of sugar beet roots, take into account the square 10 m2 in 4-times repeated with each experimental plot by weighing machinery, processed data by ANOVA. The research found that studied herbicides efficiently at 87-92%, reduced infestation annual dicotyledonous weeds and increase the harvest of sugar beet roots to 29.9-44.1%

Set Up

The experiment was set up on two types of the soil: Mollic Gleysols (FAO, 1998) and Eutric Cambisols where the presence of pathogenic fungi – sugar beet root decay agent – Rhizoctonia solani has been detected since 2005. In a two year study (2008, 2009), the experiment was set up by completely randomized block design in 4 repetitions and 16 different variants. Two beet varieties, Belinda, sensitive to pathogenic fungi R. solani, and Laetitia, tolerant to pathogenic fungi R. solani), were grown. The microbiological preparation BactoFil was applied in different amounts in autumn and spring. In addition, the nitrogen fertilizer application, based on the results of soil analysis, was varied. The following parameters were tested: amount of infected and decayed plants, root yield, sugar content, sugar in molasses and sugar yield. The best results were obtained by applying the microbiological preparation BactoFil, and by 30% reduced nitrogen fertilizer application. Preparation dosage and time of application depended on soil properties.

High Storage

Harvest quality of sugar beet varies according to soil conditions, harvester type and setting, and variety, too. Harvest quality may affect storage losses, in particular when injuries occur. To determine the harvest quality of commercial sugar beet and to quantify resulting storage losses, 92 commercial sugar beet clamps were sampled across Germany and information about harvest conditions were gathered. At IfZ, soil tare, leaf residues, topping diameter, root tip breakage and surface damage of the beets were determined. The beets were stored in 6 replicates in a climate container at 9°C for 10 weeks. The results demonstrate a rather good harvesting quality of sugar beet in Germany. Soil moisture at harvest did not affect harvest quality and storage losses. Very light, but also heavier soils lead to inferior harvest quality (soil tare, root tip breakage, damage) and slightly higher storage losses compared to the typical loam soils. Significant differences occurred between the three harvester types (companies). In general, high root tip breakage and severe surface damage of the beet was related to a high infestation with mould and rots, high invert sugar contents after storage and high sugar losses. Out of the five most planted varieties, in particular one turned out to be very susceptible to damage, resulting in high storage losses. The factor analysis suggests that the effect of harvester / harvester setting and of variety is more important for harvest quality and storage losses of sugar beet than soil conditions at harvest. Therefore, attention should be paid to optimize these conditions.
