In 2008-2010 grain yield and fodder value of winter triticale cv. Kitaro were assessed. The level of plant protection covered three technologies with various production intensity. Grain yield of winter triticale cultivated on the higher agro technical level was 7,56 t/ha and was respectively almost 36% higher than the yield obtained from standard technology. The intensity of plant protection ag...
