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 study the effect of additive intercropping series of chickpea (Cicer arietinum L.) with saffron (Crocus sativus L.) on their growth criteria and yield, a field experiment was done based on a randomized complete block design with three replications at the Agricultural Research Station, Faculty of Agriculture, the Ferdowsi University of Mashhad during two growing seasons of 2012-2013 and 2013-2014. The treatment included 100% saffron+20%chickpea, 100% saffron+40%chickpea, 100% saffron+60%chickpea, 100% saffron+80%chickpea, 100% saffron+100% chickpea and their monoculture. The trait studied were plant height, yield components, biological yield and seed yield of chickpea and the number of flowers, fresh weight of flowers, fresh weight of stigma and dry weight of stigma for saffron. The results showed that saffron intercropping series had a significant impact on plant height, number of branches, number of pods, number of seeds per pod, number of seeds per plant, biological yield and seed yield of chickpea (p≤0.01). The highest biological yield and seed yield of chickpea were observed in monoculture with 608.3 and 282.9 kg.m-2 and the minimum of these were obtained in 100%saffron+100% chickpea with 122.5 and 55.94 g.m-2, respectively. The number of flowers, fresh weight of flower, fresh weight of stigma and dry weight of stigma for saffron were significantly affected by intercropping with chickpea (p≤0.01). The highest flower number and stigma dry weight of saffron were achieved in monoculture with 103.89 and 0.47 g.m-2 and the lowest of these were obtained in 100%saffron+20% chickpea with 28.94 flowers.m-2 and 0.14 g.m-2, respectively. By increasing the chickpea ratio from 20 to 100% at additive intercropping series with saffron, the dry weight of stigma was increased by 142, 116, 41 and 5%, respectively. Therefore, we may conclude that intercropping of saffron with nitrogen fixation plants such as chickpea seems to be a rational ecological approach for sustainable management of saffron.

Saffron (Crocus sativus L.) is the most expensive spice and 95% of its global production is in Iran. In order to study the effects of cow manure and foliar spraying on criteria of daughter corms and flower yield in six year-old saffron, an experiment was conducted based on a randomized complete block design with three replications at the Agricultural Research Station, Ferdowsi University of Mashhad during two growing seasons of 2013-2014 and 2014-2015. Treatments were Yaramilla complex (A), Humestar (B), True fertilizer (C), Delfard (D), manure fertilizer as composted cow manure (E), A+E, B+E, C+E, D+E and control. Twenty t.ha-1 of cow manure were applied at the end of fall on the soil surface. Foliar nutrient treatments were sprayed at three times during vegetative stage of saffron (7 mg.kg-1). The results showed that the effects of cow manure and foliar spraying were significant on dry weight of tunic, dry weight of leaf, dry weight of corm, leaf length, leaf appearance rate, flower emergence rate, flower number, fresh weight of flower and dry weight of stigma for saffron (p≤0.01). The highest leaf appearance rate and flower emergence rate were observed in C+E with 7.34 leaves per day and 11.7 flowers per day, respectively. The maximum fresh weight of flower and stigma dry weight were obtained in C+E with 69.77 and 0.66 g.m-2, respectively. These lowest amounts were obtained in control with 27.30 and 0.26 g.m-2, respectively. The application of cow manure resulted in enhanced growth and yield of corm and flower. Also, foliar spraying improved flowering rate, flower yield and stigma yield of saffron due to increasing in production assimilates and their translocation to corm and below ground organs.

In order to investigate the effective traits on yield of saffron ecotypes, a study was carried out as a split plot in time based on randomized complete block design with three replications in the research farm of Zanjan University during the growing seasons of 2013-2015. Eighteen saffron ecotypes were studied in this experiment. The traits of number of flowers, fresh weight of flowers, fresh weight of stigma, dry weight of flowers, dry weight of stigma, stigma length and dry stigma yield of saffron were measured. The results indicated that there were significant differences among all studied traits of ecotypes except for stigma length. The correlation matrix revealed that the number of flower and dry weight of stigma had a positive and highly significant correlation with dry stigma yield (r= 0.99 and 0.70, respectively). Analysis of stepwise regression and path analysis showed that the traits of number of flowers, dry weight of stigma and dry weight of flowers were the most effective traits on dry stigma yield. Therefore, these traits can be used to achieve a higher stigma yield.
