EFFECT OF THE MONSOON CLIMATE IN PRIMORSKY KRAI UPON FORAGE PRODUCTIVITY OF WINTER TRITICALE
The article presents the results of agroecological testing of winter triticale conducted in the steppe climatic zone in Primorsky Krai in the period of 2017-2018. The aim of the research was to obtain experimental data on winter hardiness, productivity of green mass and grain of the winter triticale. It also had to highlight high-yielding varieties resistant to extreme environmental factors, which will be recommended for further study and implementation into production. For this purpose, 11 varieties of winter triticale from different regions of the Russian Federation were studied. Special attention was paid to winter hardiness and productivity. Variety testing showed that winter triticale does not tolerate weather conditions of Primorsky Krai, especially in winter and is subject to freezing. Its winter hardiness during the test period was 0.3-2.1 points, which is 2.5-4.3 points lower than that of winter rye Spasskaya local. Despite the fact that the biological yield of the green mass of the studied varieties exceeded winter rye by 2.8-13.7 t/ha, the actual yield was significantly lower due to low winter hardiness. In terms of grain productivity, winter triticale is significantly inferior to winter rye by 0.6-2.1 t/ha.
