Abstract
The paper presents the results of studies to determine the optimal density of spring triticale plants at different seeding rates in the southern agricultural zone of the Amur Region (Russia) in order to obtain an optimal grain yield. This crop is new for the Amur Region. It is considered more resistant to stressful weather factors and soil conditions and may become an important link in the production of feed grain in the region. The paper presents the results of field studies of the duration of interfacial periods of spring triticale. The influence of varieties and sowing rates on seedling density and field germination of seeds was determined, as well as the influence of varieties and seeding rates on plant survival. Also, the influence of different seeding rates on grain yield of spring triticale was studied. The paper provides an assessment of dynamics of the average grain yield of spring triticale depending on the seeding rate.
Highlights
The life cycle of plants is divided into phases according to a number of external characteristics
Meteorological conditions affect the speed of plants passing through the developmental phases and the length of the growing season, which have a consistent effect on the productivity of triticale agrocoenosis as a whole (Maltsev V.F. et al, 2002)
Observations of the growth and development of spring triticale plants make it possible to analyze the impact of external factors, varietal characteristics of the culture, and the effect of different seeding rates on the growing season
Summary
The life cycle of plants is divided into phases according to a number of external characteristics. Meteorological conditions affect the speed of plants passing through the developmental phases and the length of the growing season, which have a consistent effect on the productivity of triticale agrocoenosis as a whole (Maltsev V.F. et al, 2002). In the process of ontogenesis of spring triticale, the dynamics of the development of the onset of phenological phases and stages of orthogenesis, as well as the length of the growing season, is influenced by both the varietal characteristics of the culture and the meteorological conditions of the growing season. Observations of the growth and development of spring triticale plants make it possible to analyze the impact of external factors, varietal characteristics of the culture, and the effect of different seeding rates on the growing season. In view of the fact that this culture, unlike other grain crops, is considered more resistant to stressful weather factors
