Abstract

The effects of humic acid on some quantitative and qualitative characteristics of saffron were evaluated under field conditions. This experiment was carried out based on a randomized complete block design with three replications at the Research Farm of University of Birjand, during cropping year 2015-2016. Treatments were four levels of humic acid (0, 5, 10 and 15 l. ha-1). The results showed that humic acid improved the leaf growth indices (fresh and dry weights) and chl a content. The highest leaf fresh weight (0. 116 g. plant-1) and dry weight (0. 029 g. plant-1) were obtained 5 and 10 l. ha-1 humic acid while the lowest values were recorded in control. Also, humic acid improved the Corm growth indices (Corm number and total fresh, daughter Corm weight and diameter of daughter Corm). Stigma fresh and dry yield were influenced by humic acid in the second year. The highest stigma fresh yield (0. 7 g. m-2) and Stigma dry yield (0. 029 g. m-2) were obtained in 5 and 15 l. ha-1 humic acid. While the lowest values (with 0. 267 and 0. 022 g. m-2, respectively) were recorded in control. But, no significant difference was found in flower number and fresh total yield. Thus, results showed that application of 5 l. ha-1 humic acid is useful to improve vegetative and reproductive characteristics of saffron.
