In many three year-factorial experiments and on-farm experiments the following agronomical factors: varieties, soil tillage, quality of seed material, kind and date of sowing, plant density, rate N, P, K, irrigation, foliar fertilization, harvest date, length of vegetation period were studied. Three traits of sugar beet crop: root yield, sucrose content, technological sucrose yield were observed. The factors whose effects on investigation traits were the largest were: years, soil quality, length of vegetation period, sowing date and N rate. Relatively large effects were caused by plant density and its regularity.
