Assessment of the Effect of Foliar Silicone Fertilizer on Winter Wheat Cultivation

The aim of the conducted field experiment was efficacy assessment of foliar fertilization of Hondia winter wheat cultivar. The conducted studies concerned the wheat yield, the characteristics of grain including the macroelement content and the parameters of the obtained flour. The field experiment was conducted in the growing period of 2018/2019 in Lipnik at the Agricultural Experimental Station belonging to the West Pomeranian University of Technology in Szczecin. The experiment was conducted on light soil of good rye complex, belonging to IV b bonitation class. The factor under study in the present experiment was spraying with Polist 18 N with silicone. The effects of 4 variants were compared (without spraying, one spray – initiation of vegetation, two sprays – initiation of vegetation and shooting phase, three sprays – initiation of vegetation, shooting phase and earing phase). The experimental plant was Hondia winter wheat cultivar from DANKO Plant Breeder. Significant yield of winter wheat increase was obtained following three sprayings with Polist 18 N with silicone. The obtained results indicate the possibility of further increase in yield following the fourth spraying in the grain maturity phase. The introduction of a dose of 400 g SiO2 per hectare (three sprayings) resulted in significant changes in the qualitative characteristics of winter wheat grain cultivar Hondia and flour. There was an increase in the gluten content, value of sedimentation index, quality number and dough development time. The obtained results show that the application of Polist 18 N with silicone to winter wheat is substantiated.
