Title
Effect of seed priming and biological treatment on growth characteristics and yield of corn cv.single cross 704
Authors
Abstract
In order to investigation the effect of priming and biological seed treatment on growth parameters and corn yield of single-cross 704 cultivar, an experiment was conducted in factorial experiment based on completely randomized block design with three replications in research station of agriculture school of Ravansar in Kermanshah. two studied factors included of seed priming with distilled water in five levels and seed inoculation with five levels of Plant Growth-promoting Rhizobacteria. In this study Results 48 hours priming was not able to germinate of seeds. Also results indicated the non-significance interaction between two studied factors for all studied traits. Maximum and minimum of mean of the all studied traits belong to 24 and 0 hours seed priming, respectively.
