In the article are presented the results of phytotesting of high dispersed waste slime with increased content of iron. In laboratory conditions have been investigated the growth of three types of corn-bean crops: Pisumsativum, Phaseolus vulgaris, Glycine hispida under influence of different concentrations of waste slime (1% and 10%) with use of planetable method of couching of seeds on two types of substrates (water and soil). The following morphometric parameters of seedlings have been considered: height, length of root, above ground mass, root mass. It was found that investigated metallurgical slime has different influence on growth of corn-bean crops during initial stages of ontogenesis. The most sensitive object was Pisumsativum, the least - Glycine hispida. On soil substrates it was revealed a stimulant effect of 1% slime on seedlings of Pisumsativum. At the same time 10% slime depressed growth of Pisum and Phaseolus. It was revealed difference in slime’s bio effects on couching of corn-bean crops on two types of substrates (water and soil) contained high dispersed slime waste.
