Abstract :
This study aimed to evaluate the sowing season and sowing methods for Vicia variabilis using split plot design based on completely randomized block with three replications in Meleh-Kabud, Gahvareh, and Kermanshah, Iran during 2016-17. The first factor was sowing season (spring and autumn) and the second one was sowing method (row sowing and scatter sowing). Result showed that sowing method had a significant effect on seedling emergence percent (P<0.01). Means of this trait were 19.96% and 2.61 at row sowing and scatter sowing, respectively. Similarly, effects of both factors and their interaction were significant on survival rate (P<0.01). The higher value of survival rate as 22.6% was obtained in row sowing method in spring. It was concluded that row sowing is an optimal method in early spring for rangelands improvement in Kermanshah province, Iran.
