Impact of agro-ecological conditions and fertilization on yield and quality of triticale on pseudogley soil

Abstract

The results of the study of the influence of fertilization and calcification on the yield and yield components of winter triticale grown on low pH soil are presented in this paper. Five variants of fertilization were tested during three growing seasons. Trial treatments included different fertilization variants: V1-control, V2-N120, V3-N120P80K60, V4-N120P80K60 + 5 t ha- 1 of lime and V5-N120P80K60 + 5 t ha-1 of lime + 30 t ha-1 of manure. The results of the research showed that all yield components responded positively to the application of mineral nutrition by changing the production characteristics and grain quality. The variant with the combined application of NPK, lime and manure had the greatest positive effect on all tested parameters affecting triticale productivity. During the study, the highest yield of triticale 5.826 t ha-1 was obtained on the fertilization variant with the combined application of lime, manure and NPK fertilizers. The achieved increase in the grain yield of triticale was significant compared to the control and the NPK variant of fertilization. Highly significant positive dependencies were found between the grain yield with 1000-grain weight, and test weight and significant positive dependencies were found between 1000-grain weight and test weight. Theresearch highlighted the impact of different fertilizer treatments on the yield and grain quality traits of winter triticale.
