Under conditions of Latvia's climate, forage grasses are the main fodder source in cattle breeding. The productivity of grasslands and pastures mostly depends on cultivated grass varieties. The aim of the present research was to study photosynthesis activity and crop yield of Festulolium and Lolium x boucheanum ryegrass foreign varieties under agro-ecological conditions of Latvia. Field trials were established on sod-podzolic soil fertilized with N120 (60+60), N180 (60+60+60), P78 and K90 kg haE-1. Swards were cut three times during the growing season. The productivity of photosynthesis and biomass were dependent on the variety and mineral fertilizer rates. Some parameters were influenced by genetic characteristics of particular cultivars.
