In the 2005–2008 in IUNG-PIB in Pulawy experiments were conducted with purpose
to determine requirements of some new winter triticale varieties to main agrotechnical factors:
sowing term, sowing density and nitrogen fertisation. The investigated forms showed different
requirements in regard to all the experimental factors. Differences were shown in response of
the varieties to the factors and grouping of the triticale objects was performed.
