Abstract
Objective & Background:
The purpose of this research is to evaluate some traits such as leaf weight and leaf area, corm production, flower, and dry stigma yield of saffron at different drainage depths and distances and to provide a suitable method of annual cultivation of saffron corm in the plain and coastal areas of Sari.
Materials and methods:
In order to evaluate the effect of different drainage depths and distances on saffron, an experiment was conducted during the years 2021-2022. The treatments included drainage depths of 15, 30 and 45 cm in the main plots and drainage distances of 50, 100 and 150 cm in the subplots.
Results:
The highest number and weight of corm above 8 g (354.4 and 1571.4 g.m-2, respectively) was obtained in the treatment of 45 cm drain depth and 100 cm drain distance. According to the results, the highest number of flowers, flower weight and stigma dry weight were respectively 143.37 flower.m-2, 43.01 and 0.323 g.m-2 in the deepest drain, i.e. 45 cm deep and 100 cm drain distance, which no statistically significant difference was observed between the mentioned treatment and the treatment of 45 cm drain depth and 150 cm drain distance, as well as 30 cm drain depth and 100 cm drain distance treatment.
Conclusion:
Considering the best yield of the field, among the treatments, the treatment of 30 cm drain depth and 100 cm drain distance can have the best effect on the vegetative and reproductive characteristics of saffron in this region.
