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.

Introduction: Establishing the optimal planting date and selecting the most suitable ecotype are essential initial steps in maximizing yield. This study was carried out with these objectives in mind, contributing to the advancement of saffron cultivation in Khash County.
Materials and Methods: A research study was carried out to assess the impact of planting date and ecotype on the yield of Saffron (Crocus sativus L.) at the Agricultural and Natural Resources Research Station in the Khash region. The study employed a split-plot design based on a randomized complete block design with three replications. The main plots consisted of four planting dates: August 11, August 27, September 11, and September 27, while the sub-plots included three ecotypes: Taybad, Birjand, and Ghaen. Measurements taken included the fresh and dry weight of the stigma style, the dry weight of the stamen, and the number of flowers.
Results: The results from a three-year combined analysis indicated a significant interaction between planting date and ecotype at the 1% level. The highest values recorded for fresh and dry weight of the stigma style, dry weight of the stamen, and flower count were 72.69 kg/ha, 5.82 kg/ha, 4 kg/ha, and 56.96 flowers, respectively, observed at the interaction of the September 11 planting date and the Birjand ecotype.
Discussion: Birjand ecotype exhibited superior fresh and dry weights of stigma and pistil, dry weight of stamens, and flower count compared to the Qaen and Taybad ecotypes. The differing climatic conditions of the regions from which the ecotypes were collected may contribute to the variations in yield and the traits studied in this experiment. Previous studies indicated. The date of planting in September is a critical factor that significantly impacts the yield of agricultural products, and enhancing both the quantity and quality of the harvest.

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
