Comparing the yield of Vicia villosa under different seasons and sowing methods (Case study: Homand Absard Research Station)

The current research was performed in Homand Absard Research Station to investigate the yield of Vicia villosa under different sowing and establishment methods. Initially, the seeds of this species were collected from similar natural habitats. Afterward, seed characteristics including germination percentage, viability, seed vigor, etc., were examined. The study area is a semi-steppe region with an average rainfall of 333 mm. Two sowing methods including seeding and seeding together with rainfall storage, and spring and autumn sowing dates were considered in a split plot design with three replications. Data analysis was performed with SPSS software, and mean comparisons were done by Duncan's multiple range test. According to the obtained results, no significant differences were obtained for the yield of the seeds cultivated in autumn and spring between two sowing methods at 5% level of probability. However, the interaction between methods and season was significant and higher yield was recorded for the seeding with rainfall storage method in autumn season.
