Abstract

The nutrient management is one of the most important factors in relation to quantitative and physiological characteristics of saffron (Crocus sativus L. ). In order to investigate the effects of different of cow manure and fulvic acid levels on yield and physiological characteristics of saffron, an experiment was conducted as factorial based on a randomized complete block design with three replications at the Agricultural Research Station, University of Birjand during growing season of 2015. Treatments were four levels of cow manure (0, 10, 20 and 30 t. ha-1) and three levels of fulvic acid (0, 5 and 10 kg. ha-1). Results showed that cow manure aoolicationimproved the saffron flower characteristics (flower number and fresh total yield and Stigma yield). The highest values of total fresh weight of flower (6. 289 g. m-2) and stigma weight (0. 299 g. m-2) were obtained in 10 t. ha-1 cow manure, while the lowest amounts were for control (5. 18 and 0. 235 g. m-2). Leaf photosynthetic pigments (Chlorophyll a and total) were influenced by cow manure. Results also showed that fulvic acid has a positive effect flower number and fresh total yield, Stigma yield and average weight and SPAD. The highest of flower number (17. 29 No. m-2) and SPAD reading (14. 39) were observed in 10 kg. ha-1 fulvic acid. Different levels of cow manure and fulvic acid had a positive effect on total fresh yield of flower, stigma, total Chlorophyll content and SPAD reading. The highest dry yield of stigma (0. 085 g. m-2) was obtained in 10 t. ha-1 cow manure+5 kg. ha-1 fulvic acid. Thus, results showed that cow manure and fulvic acid application have significant impact on flower yield and photosynthetic pigments of saffron.
