Abstract
saffron (Crocus sativus L.) plant if a perennial plant and it belongs to Iridaceae family, Which is considered to be the most economically profitable plant in Khorasan province of Razavi and South. This research was carried out to evaluate the effects of summer irrigation and organic and biological fertilizers on the growth and development of saffron in Zaweh city of Khorasan Razavi with four replications during of 2017-2018. This experiment was conducted as split plotbased on a randomized complete block design. The main factor was two irrigation levels (summer irrigation and summer irrigation) and for levels fof ertilizer treatment (organic fertilizer of cattle manure, biofertilizer fertilizer, Stratigraphic Fertilizer of Iran and Control) was considered as sub plots. The results showed that summer irrigation and fertilizer treatments had significant effects on quantitative and qualitative traits of saffron. The best results of the studied traits was observed for bioweuterin treatment with biological fertilizer, in this treatment the number of flowers.m-2 was 8.05 and the weights was calculated per m2 was 46.84 mg, which in the control group was 1.93 mg.m-2 flower per square meter and dry weevil weight was 30.19 mg.m-2. According to the findings, this treatment has the highest quality yield in Saffron. Therefore, the implementation of summer irrigation and use of biofertilizers (containing Bacillus bacteria) on the farms of Zaveh County had a significant increase in quantitative and qualitative yields.
