By long-term data of mass field experiments (more than 450 opyto-years of observations) it is revealed that increases of productivity of root crops of sugar beet from boric fertilizers are almost significant (to 25-60 c/hectare), but they significantly vary depending on soil and climatic conditions it a vozdelyvaniiya, agrochemical properties of soils, ways and doses of the used boric fertilizer. It is established that on soils cespitose and podsolic, gray forest, chernozems opodzolenny a priority method of application of a pine forest is the main (to the soil), and at cultivation of sugar beet on chernozems typical and chestnut (at irrigation) - in a priority there are economic ways - processing of seeds and not root top dressing; on chernozems lixivious - all ways are almost equivalent. Boric fertilizers promote increase in sugar content: at their main introduction - for 0,7-1,4%, at not root podkormka - for 0,3-0,9% and when processing seeds a pine forest - for 0,5-0,8%. Boric fertilizers very highly pay off increases of a harvest and promote increase in payback of traditional (NPK) fertilizers for 40-60%.
