The effect of biojodis on winter wheat and spring barley organic seed germination and contamination with fungi

Abstract

This study analyses the effect of biological product biojodis and biojodis with sodium benzoate, which was used as a means to stop fermentation in biological product on germination energy and germination of organic winter wheat and spring barley seeds and contamination with fungi. It was found that biojodis and biojodis with sodium benzoate essentially increased germination energy and germination of organic winter wheat seeds compared to untreated seeds. No essential differences were observed on germination energy and germination of seeds treated with both products. Treating spring barley seeds with biojodis resulted in essential increase in value of their germination and productivity compared with seeds treated with biojodis with sodium benzoate. Treating seeds with a rate 3 l t–1 increased germination value compared to treatment with a rate of 2 l he–1. Treating seeds with both products at a rate of 3 l he–1 resulted in an essential increase in germination compared to untreated seeds and seeds treated with chemical seed treater. Treating organic winter wheat and spring barley seeds with biojodis and biojodis with sodium benzoate essentially reduced seed contamination with fungi compared to untreated seeds; however, it was markedly higher than contamination of seeds treated with chemical seed treatment maxim star. Seed contamination with fungi was more efficiently reduced by biojodis than biojodis with sodium benzoate. Greater rates of biological products were more effective as smaller rates.
