Yield of brussels sprouts hybrids during application of biopreparations

Abstract

This paper describes the influence of biopreparations on the yield of Brussels sprouts hybrids Diablo F1 and Dolores F1. In the experiments we used following preparations: Biocomplex-BTU, Phytocide-R, Azotophyte-R. Analysis of the results showed that all used preparations cause the growth of biometric indicators such as the number of leaves, leaf area, weight and number of heads, and plant height on a hybrid Dolores F1. Using Azotophyte-R during hybrid Dolores F1 growing increases yield to 5,8 t/ha and the use of Biocomplex-BTU and Phytocide-R increases it by 46% and 82%, respectively. These preparations have significant impact in growing hybrid Diablo F1 7–20 %.
