The aim of this research was to determine the effects of a proportion and a size of a vegetation area of parental lines on the number of seeds of maize hybrids ZP 42A and ZP 704. Hemp was sown in border belts of 3.2 m in width that were the isolation between experimental variants. The number of plants per area unit amounted to 55,000 and 65,000 per hectare. The inter-row distance for the female component amounted to 70 cm, while there were the following two distances for the male component: 70 cm and 50 cm. The proportion of areas under female component plants amounted to 66.7% and 72.2%. A statistically high significance of the environment (location x growing season), the inter-row distance of male component plants, the rows of female component plants and the density, i.e. the number of plants, was determined by the analysis of variance for the total number of kernels-seeds per ear of female component plants.
