Influence of seeding rates on productive qualities of winter triticale in the foothill zone conditions

Abstract

The article presents the results of experimental studies of the influence of seeding rates on the productivity of winter triticale. Depending on the variety and seeding rate, field germination ranged from 63.4 to 75.7%. Higher field germination is characterised by the winter triticale variety Zimogor from 69.4 to 75.7%. Based on the results of the research, it can be concluded that the fineness of the spike and the weight of the grain depended on the seeding rate. Increase in seeding rate led to a reliable increase in productivity of all three varieties of winter triticale. The highest yield was obtained at a seeding rate of 5 million seeds/ha of germinated seeds, and the lowest - at a seeding rate of 3 million pieces/ha. Consequently, according to the results of our research, we can conclude that the difference in yield between the variants of the experiment was determined by the ear fineness and weight of grain in it (to a less extent), and mainly determined by the number of plants preserved at the time of harvesting. The highest productivity was characterised by the Zimogor variety with a seeding rate of 5 million seeds/ha. On average, its biological yield was 7.60 tonnes/ha. The yield of the Kapriz and Valentin 90 varieties was significantly lower by 1.46 t/ha and 0.70 t/ha, respectively.
