INFLUENCE OF DIFFERENT DOSES OF ORGANIC FERTILIZER FROM POULTRY MANURE ON THE TECHNOLOGICAL QUALITY OF OIL FLAX AND BARLEY SEEDS

Abstract

This article studied the effect of different doses of organic fertilizers from poultry manure on the technological quality of barley and oilseed flax seeds. The technological properties of the seeds were determined in accordance with generally accepted methods. All the obtained results were subjected to one-factor variance statistical processing. Under the influence of various doses of organic fertilizers, the protein content in flax seeds increased by 10-12% relative to the control and showed a statistically significant positive result (F: 51.082; p<0.05). The fat content of flax increased by 0.41-0.605% compared to the control. The effect of organic fertilizer on the iodine number and the amount of polyunsaturated linolenic and linoleic acids of flaxseed was not observed. 5 t/ha of bird droppings was selected as the dose that best affected the technological quality of flax seeds. The content of raw protein in dry matter in barley seeds increased by 0.37% compared to the control variant, the fat content - up to 1%. The mass fraction of ash showed an increase relative to the control by 8.1-18.8%. The increase in the quality of barley seeds was most optimally influenced by a dose of bird droppings of 15 t/ha. The effect of various doses of organic fertilizers from poultry manure on the mass fraction of crude fiber, on the indicators of nitrogen-free extractives was determined within the control variant.
