摘要：During two years, the influence of agroecological growth conditions and seed maturity on field emergence, grain yield, above-ground vegetative mass production, above-ground dry matter production, a 1000 seed weight and grain crude protein yield of field pea was investigated. Field trial was established as randomised block design with four replicates at two locations (Osijek i Vinkovci) of Eastern Croatia characterised by eutric brown soils. Different maturity seeds of Czech spring pea variety "Zekon", were used for sowing. Significantly higher values of above-ground vegetative mass production (50.602 t/ha) and above-ground dry matter production (9.650 t/ha) across locations were found in the first year of research. Values of field emergence (88.1%), grain yield (4.464 t/ha) and a 1000 seed weight across locations were significantly higher in the second year of research.
