Sažetak
Seed ageing is an important cause of low vigor and bad field emergence, especially in adverse seedbed conditions. Therefore, in this investigation, soybean seed vigor was tested by four laboratory tests (germination energy GE, standard germination SG, cold test CT, electrical conductivity EC) and in field trial, as well (early planting dates Epd and optimal planting dates Opd). The soybean seed of 5 cultivars from Agricultural Institute Osijek, produced in the 3 years (1999., 2000., 2001.) was used in the investigation. The seed was stored in a warehouse conditions for 6, 18 or 30 months prior to testing. Tested soybean seed showed significant differences in seed vigor influenced by seed age, seed treatment with fungicide (Vitavax 200 FF), cultivar and planting date. High quality seed with GE and SG over 85%,performed quite well in both planting dates, as well as seeds with the CT over 70% or with EC under 42 μScm-1g-1. On the contrary, considering seed with reduced vigor there is a very great possibility of reduced FE especially in Epd. However, seed treatment with fungicide and sowing in optimal seedbed conditions can significantly contribute to improvement of soybean seed performance and stand establishment. Correlation analyses showed that all tested seed vigor parameters were significantly connected (sign. level
99%). At early planting, the strongest correlation was established between the field emergence and CT (untreated seed, r=0.949** and for treated seed r=0.951**) whereas in optimal planting date was between the field emergence and SG (for untreated seed r=0. 938** and for treated seed r=0.942**). Laboratory seed health testing showed significant differences in fungal disease intensity influenced by
fungicide seed treatment, cultivar and seed age. Total seed infection and infection with Fusarium spp. was adversely correlated with all vigor parameters. All tested vigor parameters of soybean seed had influence on grain yield indirectly by crop stand establishment.
