| dc.description.abstract | A field experiment was set in the period 2014-2017 on the experimental field of the Research Institute of Field Crops of the Agricultural Academy, Chirpan. Three triticale varieties were used: Colorit, Boomerang and Respect. With the aim of establishing the effect of the temperature and precipitation conditions of the year on the phenological development of triticale varieties, the sum of the active temperatures, the average temperature for the period and the sum of precipitation were calculated for each stage period. From a tillering to a maturity stage within the different varieties, a different duration of the growth stage periods is observed. These differences contribute to a better clarification of the biological requirements of the studied varieties. | sr |
