Abstract
Precision field experiments carried out in 2016 Experimental Station at the of Aleksandras Stulginskis University (Calcari-Endohypogleyic Luvisol) to assess the impact of biological preparations in spring wheat crop density, productivity elements and fertility. The experiment soil composed of neutral (PHKCI 6.8), high amount of phosphorus (226.6 mg kg"1 of P2O5), medium amount of potassium (105.0 mg kg"1 of K2O), medium humus (2.33 %). The initial size of the field - 240 m2 accounting - 128 m2. The experiment was carried out in 3 replications, arranged randomly options. Spring wheat experiment options: factor A - biological preparations: 1) without spraying, 2) sprayed BactoMix2 11 ha"1, 3) sprayed Rizobakterin 2 1 ha"1, 4) sprayed BactoMix5 1 1 ha"1. Factor B - nitrogen rates: 1) fertilized with N105, 2) fertilized with Nj65. It was found that less fertilizing background (N105) number of germinated spring wheat was essentially (from 14.0 to 14.8 units m"2) higher compared to unsprayed (P <0.050). Larger fertilization background (N165) of spring wheat germination and the quantity of productive stems was not essentially differences. Spring wheat biometric indicators of soil spray biological preparations and fertilized with different nitrogen fertilizer rates (NJOS and N165) changed by unevenly. Larger fertilization background (N165) using the product BactoMix2 1000 grain weight determined essiantially (3.7 g) higher compared to the without spraying (P<0.050). The use of biological preparations, crop fertilization little lower (N105) and higher (N165) nitrogen fertilizer rate did not material impact on spring wheat root mass, straw and grain yields, except for biological preparations a"1. Rizobakterin. This biological product is essentially increased (18.0 %, .P<0.050) of spring wheat yields, higher at atu nitrogen fertilizer (N165).
