The aim of this study is to investigate the effect of foliar application of Acadian seaweed extract and Biomix liquid poultry manure on vegetative growth, corm, and yield of saffron. The experiment was conducted in a randomized complete block design with three replications in the city of Ferdows city during the 2017-2018 growing year. Experimental treatments included four levels of Acadian seaweed extract (0, 1, 1.5, and 2 kg. l000 L-1 water) and four levels of liquid Biomix liquid poultry manure (0, 4, 5, and 6 L. l000 L-1 water). The results showed a significant effect of treatments on the studied traits, such as maximum number of flowers (99.50 N. m-2), fresh yield of flowers (33.34 g.m-2), dry weight of saffron stigma (0.341 g. m-2), dry leaf weight (0.592 g plant-1), and leaf length (63.75 cm) obtained in 2 kg. l000 L-1 seaweed extract. Besides, the results showed a significant effect of liquid poultry manure on flower number and yield (94.250 N.m-2 and 32.285 g. m-2, respectively), leaf length (60.66 cm), fresh and dry leaf weight (0.74 and 0.46 g.m-2, respectively), and total weight of replacement corm (37.02 g.m-2). Also, the least amount of the mentioned traits were observed from the control treatment. The interaction between these two fertilizers was also significant in fresh and dry leaf weight and the total and average diameter of replacement corm. Thus, fresh and dry leaf weight (210% and 273%, respectively) were highest in the treatment of 2 kg. l000 L-1 of seaweed extract and 6 L. l000 L-1 of liquid poultry manure. Moreover, total and average diameter of replacement corm (33% and 50%, respectively) were highest in the treatment of 2 kg. l000 L-1 of seaweed extract and no liquid poultry manure. According to the results of this study, the use of Acadian seaweed extract (2 kg. l000L-1 water) alone or in combination with Biomix liquid poultry manure (6 L. l000 L-1 water) can play an important role in enhancing the vegetative growth, corm, and yield of saffron.

In order to investigate the impact bio fertilizer novafol and mother corm weight on leaves growth, chlorophyll content and flower and stigma yields of saffron (Crocus sativus L.), an experiment was done as randomized complete block design with three replications in the Agricultural Research Station, University of Birjand, during the growth season of 2016-17. Experimental factors were amino acid application (Novafol, containing 28% amino-acid. Applied as corm soaking + fertigation in three levels: 0, 2 and 4 L.ha-1) and mother corm weight (0.1-4, 4.1-8 and 8.1-12 g). The effect of bio-fertilizer novafol was significant on the flower number, flower yield, dry stigma yield and chlorophyll a content. The highest flower number (16.5 per m-2), flower yield (5.63 g m-2), dry stigma yield (0.108 g m-2) and chlorophyll a content (1.09 mg. g-1 FW) were obtained from 4 L.ha-1, while, the lowest flower number (14.22 per m-2), flower yield (4.55 g m-2), stigma yield (0.085 g. m-2) and chlorophyll a (0.97 mg. g-1 FW) were gained in control treatment, but, there was no significant difference between two levels (2 and 4 L.ha-1) novafol bio fertilizer. Corm weights aslo significantly affected all studied traits. The highest stigma length (25.1 mm), flower yield (10.4 g m2), leaf length (31.42 cm) and fresh and dry weight of leaves (0.29 and 0.083 g per plant, respectively) were obtained from big corms, but the lowest of them were obtained from small ones. Interaction effect of corm weight and novafol bio fertilizer was significant on chlorophyll b and total chlorophyll contents and number of leaves per plant. The highest chlorophyll b and total chlorophyll (1.77 and 2.95 mg. g-1 FW, respectively) and number of leaves (7.58 per plant) were obtained from 4 L.ha-1 of novafol bio fertilizer and big corm. Overall, application of novafol bio fertilizer (4 L.ha-1) improved the vegetative and reproductive growth parameters. Big corms planting also had an important role in increasing the growth and yield of saffron.

The effects of application of humic acid and planting density on vegetative and reproductive characteristics of saffron were evaluated under field conditions. Treatments were four levels humic acid (0, 5, 10 and 15 kg.ha-1) and three density plantings (50, 75 and 100 corm.m-2). This experiment was carried out as a factorial based on randomized completely block design with three replications in the research farm of Birjand University, Iran, during the cropping year 2015-2016. The results showed that humic acid levels improved the corm vegetative indices (total weight of corm, fresh and dry weight of corm). The highest total weight of corm (23.09 g.plant-1) was obtained in with 5 kg.ha-1 humic acid. The results also showed that humic acid improved the saffron flower characteristics (flower number and fresh total yield, stigma fresh and dry yield) in the second year. The highest stigma fresh (1.35 g.m-2) and stigma dry (0.23 g.m-2) yield were obtained in plants treated with 10 kg.ha-1 humic acid while the lowest values were recorded in the control group. Application of different levels of planting density had a positive effect on flower number and fresh total yield, stigma fresh and dry yield in the second year of experiment. The highest of these characteristics were observed in planting density of 100 corm.m-2. Application of different levels of planting density and humic acid had a positive effect on the stigma length and stigma fresh yield. Thus, the results showed that 5 kg.ha-1 of humic acid and 75 corm.m-2 planting density have a significant impact on vegetative and reproductive characteristics of saffron.

In order to evaluate the allelopathic effects of saffron (Crocus sativus L.) corm and leaf aqueous solution on germination characteristics and preliminary growth of weed species including wild barley (Hordeum spontaneum) and couch grass (Agropayron repense) two separate experiments for each species were conducted at the research laboratory of the School of Agriculture of the University of Birjand in 2016. A factorial experiment in a completely randomized design with three replications was conducted for each species. The factors included saffron organs at two levels (leaves and corms) and water extract concentrations at 5 levels (0, 0.5, 1, 1.5 and 2 percent). The results indicated that the lowest seed germination percentage of wild barley and couch grass were observed at a concentration of 2% of leaf and concentration of 2% of corm, respectively. The results indicated that the lowest rate of germination of wild barley and couch grass were observed at a concentration of 2% of leaf and corm extract, respectively. Different concentrations of leaf and corm extracts significantly decreased the length of radicle, seedling fresh weight and seedling dry weight of two weeds. The logistic model provided a successful estimation of the relationship between leaf water extract and germination percentage of two weeds. Based on orthogonal comparison tests, the allelopathic inhibitory effects of saffron leaves and corms were the same for two weeds. The results showed that leaf extract of saffron the most influence on wild barley and corm extract of saffron the best effect on couch grass. Therefore, results of this study, confirm that can be used the allelopathic effects of saffron to reduce these two weeds in the field.

components of saffron were evaluated under field conditions. Treatments were four levels cow manure (0, 10, 20 and 30 t.ha-1) and three fulvic acid (0, 5 and 10 kg.ha-1). This experiment was carried out as factorial based on randomized completely block design with three replications in research farm of Birjand University, Iran, during cropping year 2015-2016. Results showed that cow manure improved the active ingredients of stigma (picrocrocin, safranal and crocin) in first year of study. Also, results showed that petal antioxidant compounds (total phenol and anthocyanin) and active ingredients of stigma were influenced by cow manure in second year of study. The highest safranal was obtained in plants treated with 10 t.ha-1 cow manure in first year of experiment. Results also showed that fulvic acid has a positive effect active ingredients of stigma (picrocrocin and crocin), anthocyanin and total phenol in two years of experiment and the highest rate of anthocyanin and total phenol were obtained with 5 kg.ha-1 fulvic acid while the lowest values were recorded in control. Application of different levels of cow manure and fulvic acid had a positive effect on the active ingredients of stigma in two years of experiment and anthocyanin and phenol in second year of study. Thus, results showed that cow manure and fulvic acid have significant impact on antioxidant compounds and active ingredients of saffron under field conditions.

The effects of applications of humic acid and planting density on antioxidant activities and components of saffron were evaluated under field conditions. Treatments were of four levels of humic acid (0, 5, 10 and 15 Kg.ha-1) and three densities of planting (50, 75 and 100 corms.m-2). The experiment was designed in randomized block design with three replications at the research station of the Faculty of Agriculture at the University of Birjand during the growing season of 2015. Petal antioxidant compounds (antioxidan, total phenol and Anthocyanins) and active ingredients of saffron (picrocin, safranal and crocin) were influenced by humic acid and planting density treatments. The highest antioxidant activity (69.7%) was obtained in plants treated with 5 kg.ha-1 humic acid with a planting density of 50 corms.m-2. However, no significant difference was found in phenol content under different treatments. The highest anthocyanin content (46.4 mg.100 g-1) was observed in 10 kg.ha-1 humic acid with a planting density of 75 corms.m-2. Picrocin content was influenced in response to humic acid planting density and the highest value (40.60%) was obtained from 15 kg.ha-1 humic acid with a planting density of 75 corms.m-2. The highest safranal (20.1%) and crocin (55.57%) were obtained in plants treated with10 kg.ha-1 acid humic, while the lowest values were recorded in the control (15.70%) and (43.12%) respectively. Thus, the results showed that humic acid and planting density have strong impacts on antioxidant compounds and active ingredients of saffron under field conditions.
