| Abstract | The purpose of the research was to identify the allelopathic effects of water extracts of vegetable residues of camelina sativa to sowing quality of soft winter wheat, corn and spring barley. Alelopathic activity of aquatic extracts of plant residues on seed germination was determined by direct biotesting according to the method of A. M. Grodzinsky. The influence of water extracts of biomass of camelina on germination, germination energy, length and weight of roots and seedlings was investigated. On the basis of the obtained data, an index of allelopathic activity (RI) an indicator, characterizing the direction and relative value of allopathic effects on seed germination indicators was determined. The experiment used water extracts with a concentration of 1 : 10, 1 : 50, 1 : 100. The control option was to germinate seeds in distilled water. The 1 : 100 concentration extract had a slight stimulating effect on the germination of mild winter wheat seeds (RI = 0.01) with the intensive development of the root system and a larger mass of seedlings. At a concentration of 1 : 50 allopathic index was -0,15, and at concentrations 1 : 10– -0,24. The extract has an inhibitory effect on all indicators except the height of the seedlings. The allelopathic index of low concentration of extract (1 : 100) on corn germination was 0,02. However, the use of higher concentrations of extract for seed germination caused inhibition of growth processes. With the ratio of crop residues 1 : 50, the allopathic activity index was reduced to -0,08. In this embodiment, the experiment is the lowest allopathic index by the mass of the seedlings. The extract of 1 : 10 inhibition influenced all indicators, with a generalized index of allelopathic activity was -0,17. The germination of spring barley seeds on water extracts of plant residues of camelina sativa in all options had a inhibitory effect. At a concentration of 1 : 100, the RI index was -0,02. At the specified concentration, a positive allopathic index was noted only in the height of the seedlings. Increased concentrations of extract led to growth of spring barley. At the concentration of extract 1 : 50, the allopathic activity index was -0,39, and at concentrations 1 : 10 – -0,50. Therefore, the effect of crop residues sowing on the crop of seedlings of mild winter, spring barley and corn is analyzed. It is established that the extract of plant residues of sowing in a concentration of 1 : 100 has a positive effect on the development of soft winter wheat and corn seedlings, and increased concentrations (1 : 50 and 1 : 10) – inhibit growth processes. All tested concentrations of extract of biomass of camelina adversely affect the germination of spring barley seeds. | ||
