Abstract

In the paper are presented relationship between standard germination (SG) and field emergence (FE) with field emergence index (FEl= field emergence/ standard germination x 100). Index was showed under influence of few important factors of seed vigor: cultivar, seed age and seed treatment as well as different seedbed conditions. Results showed that the seed with optimal vigor (SG≈90%) has very similar SG and FE values (SG≈FE, FEI≈100). That means that during the sowing of such seed, there was no risk if we use untreated seed or if there are unfavorable field conditions. On the contrary, by seed with reduced vigor (SG<80%) SG and FE values are very different (SG>FE, FEI=40-100), there was a very great possibility of reduced FE. lf we use such seed, fungicide seed treatment and sowing in optimal seedbed conditions can significantly contribute to the repetition of laboratory results in field condiitons (SG≈FE, FEI≈100). This knowledge can significantly reduce risk in sowing and contribute to improvement of soybean seed performance and stand establishment.
