The influence of analyzed leaf fertilizer and nitrogen fertilizer on winter wheat productivity

Field experiment was conducted in 2013 atASU Experimental Station.The soil type – IDg8–k (LVg–p–w–cc). Thecombination of K–Leaf and Prolis substantially increased winter wheat grain yield in all fertilization groups. After Spraying winter wheat with foliar fertilizer Pompa the greatest yield increasment compared with the control (1.10 t ha-1) was set when the winter wheat nitrogen fertilization rate was N120. However, after increasing the rates of nitrogen fertilizer, the efficiency of pothasium fertilizer decreased significantly. K-Leaf and Prolis essentially increased the winter wheat ears productivity . Essential increasment of wheat ears productivity was determined in all nitrogen fertilization rate groups. Foliar fertilizer Pompa increased the wheat ears productivity as well. The combination of foliar fertilizers K–Leaf and Prolis, increased the mas of 1000 grains in all experiment variations comparing with the control group. The highest weight of 1000 seeds (37,60 g) was determined after using N180 and adding foliar fertilizer Pompa. The highest increasement in the count of wheat grain was determined after using foliar fertilizer PompaVytauto Didžiojo universitetasŽemės ūkio akademij
