“…Additionally, the low yield of saffron has been attributed to conventional agronomic practices, low corm progeny, and the associated microbial infections [10]. Therefore, soilless cultures and cultivation systems under controlled conditions are considered suitable replacements for conventional saffron cropping and for the production of pathogen-free corms [8,[11][12][13][14][15][16][17][18]. Moreover, such systems can increase saffron yield [19].…”

Indoor saffron farming systems under controlled conditions are required to meet the high demand for this valuable crop. The aim of the present study was to determine the flowering, growth, and yield responses of saffron grown using nutrient solutions with different electrical conductivity (EC) levels (0.7, 1.4, and 2.1 dS m−1). Sprouted saffron corms were cultured for 24 weeks under a volcanic rock-based aerated continuous immersion system. Vegetative growth and leaf gas exchange, but not flowering, were affected significantly by EC levels. The optimal EC in a balanced nutrient solution was 0.7 dS m−1, at which level the highest plant height, leaf area, biomass, photosynthetic rate, number of daughter corms, and percentage of corms ≥ 25 mm were recorded. An EC level of 2.1 dS m−1 decreased the photosynthetic rate, stomatal conductance, and transpiration rate of saffron but increased biochemical stress marker levels and elevated various antioxidant defense enzyme levels significantly in saffron leaves, possibly reflecting a defense response to the cellular damage provoked by the higher EC level. In terms of nutrient solution EC, 0.7 dS m−1 was optimal in saffron, whereas 2.1 dS m−1 caused oxidative stress that led to reduced growth and daughter corm production.

“…Poggi et al [11] determined the quality of saffron obtained from corms stored in incubation conditions according to ISO 3632; they observed an improvement in the saffron quality obtained from incubated corms, though the times of incubation for which these results were obtained were not specified. In this study, when the corms were not stored in ULO chambers the incubation did not produce a positive effect on the most of the parameter ISO analysed, but an improvement in the colouring strength was observed in corms previously stored in ULO chamber and incubated for 30 and 60 days.…”

The Combined Effects of Vegetative Stage Corms, Ultra Low Oxygen Cooling Storage and Incubation Time on Crocus sativus L.

In order to extend the flowering season of Crocus sativus L. more time than the methods developed to date and to study their limits, a multivariable trial was carried out with the following factors: vegetative stages of the corm; ultra low oxygen (ULO) cooling storage and incubation time. The main production parameters and the quality saffron were studied. The usage of corms lifted 40 days earlier leaf senescence (V3–40 d) was not technically viable. No benefits were obtained from corms lifted shortly after leaf senescence (V3). Most of the parameters decreased with increasing of storage in ULO chambers for the vegetative stages studied. The corms lifted 20 days earlier leaf senescence (V3–20 d), stored from 0 to 120 days in ULO chambers and incubated 30 and 60 days provided greater number of flowers and more weight of saffron than corms non-incubated. A predictive model was obtained which allows to know the saffron yield in corms lifted in the stage V3–20 d, stored from 0 to 180 days in ULO chambers followed by incubation from 30 to 120 days. The combination of the three factors studied allowed to extend the Crocus sativus L. flowering from October to early February with an acceptable saffron yield and a quality similar than saffron grown traditionally.

“…The term "saffron" refers to a spice that is typically derived from the desiccated stigmas of the Crocus sativus plant, which has been predominantly cultivated for economic purposes since ancient times. Saffron holds the distinction of being the most expensive spice in the world and is often referred to as "red gold" [1,2]. The dried crimson stigmas of the Crocus flower are considered to be its most valuable component.…”

Traditionally grown in soil, saffron cultivation has been plagued by limited arable land, variable climate conditions, and soil-borne diseases. Phenological studies of the crop during each of its growth stages are crucial for mitigating the detrimental consequences of climate change, to which saffron crop is extremely susceptible. These also help in anticipating the future farming systems that involve crop cultivation methods, irrigation, field, and crop management. In this study, we assess the adaptability of saffron to soilless cultivation. In order to evaluate the performance of saffron grown in soilless media, a crop experiment was carried out over the course of two years, beginning in 2020 and continuing into 2021. Bulbs were planted in plastic polytunnels under two experimental treatments viz. soil-based (PS1) and soilless (PS2), supplemented with adequate nutrients. To evaluate the performance of saffron in soilless culture and to compare it with protected soil-based cultivation, saffron growth indicators were measured a total of twenty-five times at intervals of around twenty days during the entire growing period. The study of growth indices demonstrated that the PS2 (protected soilless cultivation) outperformed PS1 (protected soil-based cultivation) in terms of growth of organs (foliage, roots, mother bulbs, daughter bulbs) and biomass accumulation. In light of these findings, it has been demonstrated that soilless cultivation can be an effective method for the production of saffron.
