The nutrient management is the most important factors in relation to quantitative and qualitative characteristics of saffron (Crocus sativus L.).

Materials and methods

In order to investigate the effects of different of chicken manure levels on vegetative and reprouductive characteristics of saffron, an experiment was conducted as randomized complete block design with three replications at the Agricultural Research Station, University of Birjand during growing season of 2015. Treatments were 4 levels of chicken manure (0, 5, 10 and 15 t.ha-1).

Results and discussion

yield of fresh flower, dry weight of stigma and Corm weight with scale were influenced by chiken manure treatments. The highest yield of fresh flower (19/26 g.m-2) and dry weight of stigma (0/58 g.m-2) were obtained in plants treated with 5 t. ha-1 chiken manure while the lowest values (13/93 and 0/26 g.m-2) was recorded in the control. Results showed that chiken manure improved the leaf growth indices (length, dry weight of leaf and number of leaf) and photosynthetic pigments (chl a, chl b, total chl and cartenoid). The highest length, dry weight of leaf and photosynthetic pigments (chl a and chl b) were obtained in plants treated with 15 t. ha-1 chiken manure. but, not significance difference between treatments 5, 10 and 15 t. ha -1 and the lowest values were recorded in the control.


Thus, results showed that chicken manure (5 t. ha-1) hase strong impact on vegetative and reprouductive characteristics of saffron under field conditions.
