Effectiveness of using the biological preparation Albit to increase the productivity of spring barley varieties

Abstract

Purpose. The purpose of the research was to studythe effectiveness of the biological preparation Albit on theelements of the crop structure and the yield level of springbarley varieties.Methods. Field (research of yield level), laboratory(determination of elements of the crop structure) and statistical(processing of research results) methods wereused. The object of research is three varieties of two-rowspring barley of Ukrainian selection: Vodogray, Doridniyand Patritsii. The scheme of the experiment included thefollowing options: no treatment (control); pre-sowing treatmentof seeds with biological preparation Albit; pre-sowing treatment of seeds + foliar fertilization with biological preparationAlbit. The following parameters were studied: plantheight, ear length, number of grains in an ear, weight ofgrain from an ear, weight of 1000 grains, yield. Statisticalprocessing of research results included dispersion analysisusing the «Statistisa» program.Results. Based on the results of the research, selectthe option of pre-sowing seed treatment + foliar feeding ofplants with the biological preparation Albit. The Doridniyvariety was noted as the tallest – 77.5 cm, and the Patrytsiivariety (67.2 cm) was the least short. According to thelength of the ear, the Patritsii variety was distinguished –11.7 cm. The highest grain size of the spring barley earwas noted in the Vodogray variety – 28.9 grains. Thespring barley variety Patritsii (1.16 g) was characterizedby the largest mass of grain from an ear. A large and fullgrain of spring barley was also noted in the Patricia variety(45.4 g).Conclusions. According to the elements of the cropstructure and the yield level of spring barley, an experimentoption of complex treatment with the biological preparationAlbit was selected. The spring barley variety Patritsii wascharacterized by high productive potential.
