Abstract

Forage pea (Pisum arvense L.), is increasingly being planted in Croatia and its environment to produce high-quality forage. Seed production of pea is very complex process, mostly because of the plant structure and plant height. Plant height at the end of the growing season varied between 1.5 to 2 meters due to which lodging can occur because of the weight of the pod, which significantly complicates harvest. In agricultural production the yield is under the influence of plant genetic potential and environmental factors especially of the amount of precipitation during the growing season. In the work an analysis of seed pea production of variety Osječki zeleni at the Agricultural Institute Osijek depending of climatic conditions for the nine year period (2004-2012) were made. Analyses showed the large fluctuations in sin yield, germination and 1000 seed weight and oscillations in the amount of precipitation during the growing period of winter peas in the analysed years. Pearson correlation analysis showed a lack of relation between yield, germination and 1000 seed weight. There was no correlation observed between tested parameters and the total amount of precipitation during the growing period, and between analysed parameters and the amount of precipitation per month, from which it can be concluded that the observed parameters were substantially influenced by other environmental factors.
