The influence of mineral nutrition on changes of the quantitative values of photosynthetic parameters have been studied during vegetation period. The investigations were carried out in Gorni Lozen Experimental station on the leached vertisol, chromic luvisol. It was found that the optimal values of leaf area index, photosynthetic potential and dry biomass accumulation were formed under fertilizer application N- 20kg/da and P- 15 kg/da, nondeficient water regime and plant density 5500 plants/da.
