Description
Summary:The results of three years of field research in conditions of low-fertile sod-podzolic sandy loam soil of the Kaluga region on the study of growth, development, and seed productivity of narrow-leaved lupin during foliar fertilization of plants with BorSTART, MicroStim-Marganets, and Novalon 19-19-19+2MgO+ME fertilizers are presented. The use of micronutrients increased the height of narrow-leaved lupin plants, starting from the flowering phase and the leaf area from the budding phase to the end of the vegetation of plants. The largest leaf area in the flowering phase was found in options with the treatment of plants with micro-fertilizers BorStart – 480.2 cm 2 /plant and Microstim Marganets – 475.3cm 2 /plant. The treatment of plants with micronutrients exceeded the control variant by weight of the aboveground mass in the phase of glaucous pods by 8.4–11.6%. The best results were obtained when treating plants with boric micro-fertilization (BorStart). Micro-fertilizers increased the yield of narrow-leaved lupin seeds in an average of 3 years from 0.16 to 0.38 t/ha compared with the control. The highest seed yield was when processing plants with chelated forms of micro-fertilizers – Novalon and MicroStim Marganets. The use of micro-fertilizers led to an increase in the content of crude ash and crude protein in lupin seeds.
