Sažetak
Two-year investigations (2006 and 2007) were conducted within the three-year maize-soybean-wheat crop rotation with the aim to assess the influence of two cropping systems, conditionally marked as high-input and reduced-input systems, and of plant density on soybean seed yield and yield components of two new genotypes. Cropping system intensity had a positive effect in both years on soybean seed yield, seed number and seed weight per plant. In 2007, cropping system intensity had a positive effect also on number of pods per plant. Plant density had no influence on soybean seed yield. The highest pod and seed number and seed weight per plant were achieved at 35 plants m-2. Soybean genotype AF-4 achieved in both years significantly higher seed yield. Abiotic stress (high temperature, smaller amount of precipitation and its less favourable distribution) during the 2007 year had adverse influence on seed weight per plant and 1000 seed weight, which was eventually reflected in lower yield especially of genotype AF-4.
