Abstract

This study was conducted to study the effects of mother-corm size (0-4, 4. 1-8 and 8. 1-12 g) and different organic fertilizers (such as cow Manure, Humic acid (Humax® 95– WSG), an organic-mineral-based emulsion (Omic® ) and unfertilized control) on flower and corm yield of saffron. The experiment was conducted as factorial layout based on a randomized complete block design with three replications in the Research Complex of Medicinal Plants, ACECR of Southern Khorasan Province, Iran durung growing season of 2017-2018. Studied traits were dried stigma weight, dried flower weight, number of flowers, number of buds, dried bud weight, total number of corms and total weight of corms. According to the results, mother-corm size significantly affected these studied traits. The highest and lowest amount of traits were obtained in big-and small-sized corms, respectively. Dried stigma weight in big-sized corm with 82. 22 mg. m-2 was about 190 times bigger than small-sized corm. In addition, the highest number (466. 36 corms. m-2) and weight (936. 55 g. m-2) of daughter corms were belonged to mother-corm size between 8. 1 to 12 g. These results justify bearing the cost of providing big corms (over 4 g) in saffron cultivation. Evaluating the main effect of nutrition factor revealed no significant impact on most studied traits. Comparing the slope of Linear regression between dried stigma weight and corm size showed that the highest yield increasing happened in Omic treatment (12. 91 mg in exchange for one unit of mother corm weight increasing). These results clearly showed that despite significant effect of mother corm size on yield of saffron, using organic fertilizers has no significant effect on these traits in the first year. However, using organic fertilizers might have positive effects in the next coming years that needs to be studied.
