The study of biological activity of the experimental samples of new biofertilizers on spring wheat

The article presents data on the study of biological activity of the experimental samples of new biofertilizers on the Triad spring wheat variety in laboratory and field studies. Treatment of wheat seeds before sowing increases germination energy by 9-15%, depending on the bio-fertilizer used and its concentration, improves the growth of seedlings: the size of the primary leaf increases by 15-20%; the germinal root - by 10-15%; the number of lateral roots increases by 20-40%, depending on the treatment option. The study of the antioxidant status (dynamics of peroxidase, catalase) in response to the seed treatment reaction revealed the adaptogenic mechanism of action of the new bioorganic fertilizer. The difference in peroxidase activity between the experimental and control samples was more than 3.4 times with positive dynamics; catalase activity with negative dynamics was more than 2 times. The treatment of Triad spring wheat with a prototype bioorganic fertilizer (7H) increases yields on average according to the repetition variants, by 15.8% compared with the control without treatment, and a drug such as 4H showed an increase of 57% in some repetitions, which naturally requires a more extensive study of the effect of this bioorganic fertilizer. A high yield increase by 34.7% was noted on experimental plots with 1C treatment. The use of new biofertilizers helps to increase the yield of grain crops, in particular spring wheat, due to its growth-stimulating effect on all plant organs, including biomass and the root system. Therefore, these drugs can be considered as promising biostimulants.
