Abstract
The harvest index of grain can be used as indicator for the potential yield of crop. The aim of this study was to determine the variation of the harvest index for wheat and triticale and differences in monocrops and intercrops systems of cultivation under different field environmental conditions. The experiment, carried out in field conditions for two consecutive years, was designed according to a randomized block system so that each species was sown in two cultivation systems as a single crop and a combined crop (wheat + pea and triticale + pea) in four replicates. The results show that, in the first year of the experiment, the value of the harvest index varied from 32.5% (triticale + pea) to 39.3% (wheat monocrop), while in the second year of the research, the value of the harvest index varied from 26.4% (wheat + pea) and 28.1% (triticale + pea). As for the components of harvest index, values of weight of grains spike-1 and weight of total above ground biomass were higher in intercrops than in monocrops system of cultivation. It can be concluded that the intercropping of cereals (triticale and wheat) and forage crops (pea) provided positive effects on weight of grains spike-1 and weight of total above ground biomass and does not diminish harvest index when compared to standard system of cultivation.
