Skystųjų amidinio azoto trąšų su magniu lyderis mg poveikis vasariniams kviečiams

Abstract

The study aims to find out how the liquid amide nitrogen fertilizer with magnesium and sulfur influenced the productivity of spring wheat. The experiment was carried out in a calcareous deeper luvisol (Calcaric Luvisols), which under alkaline and neutral and (pHKCl 6.8), high phosphorus (230 mg kg – 1 P2O5), the average amount of potassium (152 mg kg – 1 of K2O), low nitrogen in the soil. Liquid amide nitrogen fertilizer (LEADER Mg) positively influenced the productivity of spring wheat. The highest grain yield positive changes to get spring wheat tillering stage at the end of fertilization from 0.75 to 2.5 % solution, and booting stage – from 0.5 to 0.75 % concentration. Grain protein content tends to rise, increasing the concentration of fertilizer solution, but substantial effects were only using 0.75 % solution. Sedimentation values had a greater impact on plant fertilization rant at the beginning of 0.5–0.75 % concentration.
