The strict 2-factor field experiment was carried out over 2005-2007 at the Mochełek Experiment Station of Bydgoszcz University of Technology and Life Sciences. Three pea cultivars, namely ‘Kolia’, ‘Wenus’ and ‘Winerek’ were cultivated according to four technologies: extensive, low-input, moderately intensive and intensive differing in the use of industrial means of production. LAI, chlorophyll content in leaves and yields of total biomass and seeds were not affected by different input of industrial production means used in low-input and intensive technologies. In spite of quite different moisture conditions over growing periods, in generative phase especially, pea cultivars yielded similarly. Semi-leafless ‘Wenus’ cultivar showed lowest, while traditional ‘Kolia’ and ‘Winerek’, highest and similar LAI. Harvest index in extensive and low-input technologies as well as in low-input and intensive technologies was statistically similar. The technologies used differentiated neither the harvest index nor chlorophyll content and seed yield in cultivars tested.
