Variety and quantity of seeds as factors affecting yield and yield components of winter triticale

Abstract

This paper analyzes the influence of different quantities of seeds (300 and 360 kg ha-1 ) on the yield and yield components in 5 varieties of winter tricale (Odissey, Kg-20, Triumph, Rtanj and Tango) grown in the northern part of Montenegro during two growing seasons (2010/11 and 2011/12) on river alluvium soil type. During the trial, in both years of testing, all varieties were fertilized with the equal amount of NPK fertilizer in a ratio of 90:80:80. It was found that all of the three individual factors: variety, quantity of seeds and climatic conditions in the years of testing had a significant influence on the yield and other observed parameters. The test results showed that, on average, for all cultivars and both applied quantities of seeds, the highest yield was obtained with the Tango variety, while the lowest with the Kg-20 variety. It was also observed that the hectolitre weight in the tested triticale varieties were higher when applying a higher quantity of seeds. The application of a smaller quantity of seeds led to a significant increase in the 1000 grain mass in all cultivated varieties compared to the application of a higher quantity of seeds and it was also higher in the second study year.
