Stimulating effect of biologically active substances on the initial growth processes of spring wheat

The results of determining the values of germination energy, germination, linear growth, weight of parts, sugar content in spring wheat plants in the phenological phase of the third leaf are presented. Compared with the option without fertilizers, all the preparations used had a positive effect on the germination energy of spring wheat seeds – by 4.2 % mineral fertilizers and potassium humate, by 5.6% albite, the greatest effect was exerted by the use of aminocate – by 8.3 %. The germination of spring wheat seeds in all variants of the experiment was high and reached a maximum value of 100%. The efficiency indices (leff ℓ) and (leff m) of the use of fertilizers, biologically active substances and potassium humate for linear growth of spring wheat plants is a dimensionless value, differences in options relative to the option without fertilizers amounted to more than 7...15% for mineral fertilizers, 13...18% for albite and potassium humate, the highest efficiency was It is determined in the variant from the introduction of aminocate by 20 ... 26%. The differences regarding the variant of the lowest concentration of this fertilizer amounted to 10...12% for albite, 6...9% for potassium humate, the highest efficiency was determined for aminocate – 20...33%, respectively. A low variation in signs of germination energy, grain germination, linear growth, plant weight and sugar content was found, the coefficients of variation are from 4% to 9%. The average variation of the signs is established for the indicators plant height and plant weight, the coefficients are from 11% to 14%. The linear regression of the indices of linear growth efficiency (lff ℓ) and plant mass (lff m) to the variable germination energy (%) increases and is a positive value. The coefficient of determination R2 (the square of the correlation coefficient) is close to one.
