Abstract

In this research the change trends of weight and number of saffron corms during different years of cultivation based on furrow and basin irrigation were investigated. The results showed that the number of corms under furrow irrigation method was more than other irrigation method. The corm weights for most of times were higher in furrow irrigation. The total number of saffron corms and corm number less than 4 g were increased until six years and afterward it was decreased. The weight and corm number between 4-8 g and less than 4 g increased until five years after cultivation and after that was decreased. But, total weight of saffron corms and corm number by weight with more than 8 g decreased since the first year of cultivation.
