Abstract

The results of the three-year researches (2008 – 2010) concerning the dynamics definition of the photosynthesis pigments formation in durum spring wheat variety Kharkivs’ka 41 while using urea additional fertilizing and micronutrient elements are given. The significant influence of the researched factor on chlorophylls and carotenoids content in the plants leaves is determined. The advantage of the complex use of urea (Nm 30kg/ha) and Crystalon on the chlorophylls and carotenoids content increase in the plants leaves is defined. There is the direct correlation between the content of pigments in plants leaves, the index of leaf surface and grain productivity.
