The research was conducted in split plots with a basic RCBD(Randomized Complete Block Design)over two consecutive years (2020-2021and2021-2022) at ACECR's research complex for medicinal plants.The experimental treatments consisted of two levels of drought stress (50% and 100% of saffron water requirement) and six levels of fertilizer (control, 100% NPK, 50% NPK, 50% NPK with three biofertilizers, 50% NPK with four biofertilizers, and three biofertilizers). Due to increased drought stress, the nitrogen levels in saffron leaves and corms rose, whereas the phosphorus content in the leaves decreased significantly.These findings suggest that heightened drought stress can result in reduced phosphorus levels in saffron leaves. potassium content in saffron leaves remained unchanged under drought stress, but significantly increased in corms. In general, saffron leaves accumulated significantly higher amounts of nitrogen, potassium, iron, and zinc compared to the corms except for phosphorus.Fertilizer treatments significantly affected the levels of nitrogen, phosphorus, and potassium in saffron leaves and stems, while iron and zinc levels remained unaffected. Since daughter corms store phosphorus effectively from chemical fertilizers and saffron yield depends on the amount of phosphorus in daughter corms, it is not advisable to completely replace chemical fertilizers with biological fertilizers.The level of potassium in saffron leaves and stems was not affected by the fertilizer treatments, suggesting that the application of fertilizer did not impact potassium absorption. while the level of safranal was higher in the first year.Additionally, it was observed that drought stress did not significantly impact the levels of any of the apocarotenoids examined in this study. The overall conclusion is that it is possible to enhance the quality of saffron and make up for nutrient deficiencies through the concurrent application of biological and chemical fertilizers in saffron farms even under drought.However further research is necessary to clarify the unknown aspects of this area.

Scientometrics or bibliometric analysis is one of the common methods for evaluating scientific production and activities and research management. This method is a quantitative approach to measuring scientific information in various fields of science. This method of analysis can reflect the latest scientific developments, research directions, and important research topics. In this study the documentation of national conferences of saffron and the quantitative evaluation of scientific information published in these conferences was evaluated. So far, seven national conferences on saffron have been held in Iran, the first of them was held in Qaen in 1988 and the last one was held in Birjand in 2024. The provinces of South-Khorasan (three times) and Razavi-Khorasan (four times) have been the only organizers of the national conferences of saffron. So far, 98 researchers have been the members of the scientific committee of these seven conferences. Abbas Hemmati-Kakhki and Abdullah Mollafilabi have been the members of this committee in all seven conferences. During the seven sessions of this conference, 601 articles have been published, the largest number of these (239 articles) belongs to the seventh conference, which was held by the University of Birjand. The highest ratio of the number of research articles to review articles was recorded in the fourth session of conference at Bozorgmehr Qayenat University.Researchers from Razavi-Khorasan and South-Khorasan provinces have participated in 271 and 156 articles, respectively, during the seven conference sessions as authors, and in this respect, they have a much higher share compared to the other provinces of the country.Overall, the results indicate the increasing attention of researchers in different provinces of Iran to conducting research related to saffron, which by focusing the implementation of future research on emerging aspects and promoting the results of previous research at the field level.,

Saffron is considered as a strategic crop for Iran due to its food, cosmetic, health and medicinal uses, high economic value and adaptability to the arid climatic conditions. the research trend was evaluated during the seven sessions of the Iranian National Conference of Saffron. The first of them was held in Qaen in 1988 and the last one was held in Birjand in 2024. Research topics were divided into eight main axes, 17 branches, and 98 subgroups. out of 601 articles presented at seven sessions of the national conferences of saffron, 236 articles (39.3%) dealt with the subject of production and cultivation, 90 articles (14.9%) with saffron uses and applications, 77 articles (12.8%) with harvesting and post-harvest issues, 73 articles (12.1%) with economic issues, 55 articles (9.1%) with genetics, breeding and biotechnology, 24 articles (0.4%) with pests and diseases, 19 articles (3.2%) with mechanization and 27 articles (4.5%) with other topics. The most important ecological and agronomic issues that have recently received more attention include the effect of climatic factors on saffron, the allelopathic effects of saffron, crop rotation, pretreatment of corms with growth hormones, and the most important issues that have been considered in most conferences include corm weight and planting density. Some agronomic issues such as planting date, corm planting bed, corm specific propagation, corm storage conditions, and soil physical properties have received less attention from researchers. Indigenous knowledge and agrotourism are also among the issues that, although they have recently received more attention from researchers, have not yet been sufficiently researched.

This study was conducted to investigate the effect of sheep manure and sulfur on biochemical traits and active ingredients of saffron during 2019-2020 in the Sarayan region in a factorial manner and a randomized complete block design with three replications. Experimental treatments included sheep manure at four levels (0, 20, 40, and 60 t. ha-1) and sulfur at three levels (0, 200, and 400 kg. ha-1). The results showed that sheep manure and sulfur were significant on the biochemical characteristics of stigma (antioxidant, phenol, and anthocyanin), effective substances of stigma (picrocrocin, crocin, and safranal), and biochemical characteristics of leaves (chlorophyll a, b, total, and carotenoid) of saffron. The treatment of 60 t. ha-1 of sheep manure has the highest amount of antioxidants (30.46%), phenol (62.52 mg. 100 g dry weight-1), anthocyanin (33.41 mg. 100 g dry weight-1), picrocrocin (33.00 absorption of 1% aqueous solution at 257 nm), crocin (285.667 absorption of 1% aqueous solution at 440 nm), safranal (34.56 absorption of 1% aqueous solution at 330 nm) and chlorophyll b (0.048 mg. g fresh weight-1). With a consumption of 400 kg. ha-1 of sulfur, antioxidant 12.31%, phenol 0.35%, anthocyanin 31.56%, picrocrocin 30.95%, crocin 48.48%, safranal 11.23%, chlorophyll a 16.80%, Chlorophyll b 8.33% and carotenoid 16.14% increase compared to the control. Also, the highest amount of phenol (62.73 mg. 100 g dry weight-1), anthocyanin (29.63 mg. 100 g dry weight-1), crocin (287.33 absorption of one percent aqueous solution at 440 nm), safranal (38.81 absorption of one percent aqueous solution at 330 nm), total chlorophyll (1.026 mg. g fresh weight-1) and carotenoid (1.026 mg. g fresh weight-1) at the level of 60 t. ha-1 of sheep manure and 400 kg. ha-1 sulfur was obtained. In general, the results showed that sheep manure and sulfur had a positive effect on biochemical traits a

Obesity and overweight are associated with many chronic diseases, including diabetes and increased inflammation. The aim of this study was to investigate the effect of eight weeks of saffron supplementation along with resistance training on leptin, interleukin-6, , insulin and insulin resistance levels in overweight men. 40 overweight students were randomly divided into 4 groups: exercise (n=10), exercise + supplement (n=10), supplement (n=10), and control (n=10). The exercise group performed resistance training for 8 weeks, 3 sessions of 90 minutes each week in the evening. The supplement and exercise + supplement groups used saffron tablets at a dose of 30 mg as a supplement. Blood samples were collected in two stages, pre-test and post-test, to measure plasma levels of leptin, interleukin-6, insulin, and glucose. Insulin resistance values were calculated from blood glucose and insulin concentrations. Paired t-test results showed a significant decrease in the serum levels of interleukin-6, glucose, insulin and insulin resistance in the post-test of the exercise, exercise + supplement and supplement groups compared to the pre-test (P<0.05). The results of the one-way analysis of variance test showed a significant difference in the levels of leptin, interleukin-6, glucose, insulin and insulin resistance between the research groups (P<0.05). The levels of interleukin-6, leptin and serum glucose in the exercise, exercise + supplement and supplement groups were significantly lower compared to the control group. Also, the levels of these variables in the exercise + supplement group were significantly lower compared to the exercise and supplement groups (P<0.05). These results indicate that the combination of saffron supplementation and resistance training had greater effects compared to the effects of each of them alone.

Introduction: Saffron (Crocus sativus) is a flowering plant of the genus Crocus in the family Iridaceae. Saffron as the most expensive agricultural and medicinal plant has a unique status among industrial and export products, and important for producing employment opportunities. Soil fertility management is a proper strategy for increasing soil organic matter, strengthening microbial communities, preserving biodiversity, enhancing agricultural input efficiency, and eventually improving plant quantitative and qualitative yields. To attain this goal, the fertilization management program should be designed to increase nutrient use efficiency. Optimal nutrient delivery, controlled-release fertilizers, integrated fertilization management, the use of organic nutrient resources, and beneficial symbiotic microorganisms with plant roots are all examples of methods that helps achieving nutrient use efficiency. Chemical fertilizers are the most often used fertilizers in saffron fields, and their excess can jeopardize farmed soil and water quality, and reduce the yield of saffron. As a result, biological fertilizers have attracted more interest for being more safe, low-cost, and have fewer negative environmental effects. Therefore, the present study was conducted to investigate the effect of the weight of the saffron peduncle, mycorrhizal fungi, and Azotobacter biofertilizer on the growth and yield of saffron, so that by selecting the best amount of biofertilizers and the appropriate weight of the saffron peduncle, and as a result, reducing the use of chemical fertilizers, steps can be taken to develop the cultivation and improve the yield of this important medicinal plant.

Introduction:
Agriculture, especially saffron plantations, is exposed to climate change. This is serious in the case of Sarayan city, which was one of the main centers of saffron production, and for this reason, saffron farmers have faced food insecurity and job loss or change. At the same time, these areas have faced a remarkable decrease in precipitation and exposure to the adverse consequences of global warming. Climate Smart Agriculture (CSA) practices seek to use new methods of saffron management while creating flexibility and adaptability to the effects of climate change and increasing saffron production. This study helps to understand the status of implementation of smart climate on smallholder farmers in the villages of Sarayan city. This study used descriptive statistics to describe the socio-economic characteristics of smallholder farmers and identified the main needs, practices and limitations of climate smart agriculture practices.
Materials and Methods:
Climate-smart agriculture is an approach to identify production systems that can best respond to the effects of climate change and adapt these systems to local conditions. This study, with the descriptive-analytical method and the use of questionnaires and targeted sampling in 13 villages that have the highest production of saffron, to describe the socio-economic characteristics of smallholder farmers in four villages of Sarayan city and to identify the main needs, methods and limitations Climate smart agriculture is used. The results show that the average saffron farmer is 40 years old, with a family size of 5 people and 21 years of farming experience, and cultivates in a land of 1 hectare. The majority of saffron growers have accepted at least one feature of climate smart agriculture in the management of saffron farms. The most chosen strategies of saffron growers are adaptation, reducing the effect of climate change and profitability,
