“…In this study, the effect of foliar fertilization on saffron yield indicated an increase in the flower number in the highest concentration treatment only. ese results do not completely agree with the findings of other researchers who observed a beneficial effect of foliar fertilization on the yield components and growth characteristics of saffron (Khorramdel et al, 2015;Rabani-Foroutagheh et al, 2013). Instead, the present results revealed that a one-time treatment with foliar fertilizers did not significantly affect saffron yield.…”

“…e efficiency of fertilizer utilization by a crop is determined by the method of application, time of incorporation, and the rate of decomposition in the soil (Achieng et al, 2010). e application of various fertilizers by foliar spraying is a new approach to supply nutrients through the leaf, which is increasingly used in many saffron farms (Khorramdel et al, 2015).…”

Effects of Inorganic and Foliar Fertilizers on Antioxidant Capacity and Flower Yield of Saffron (<i>Crocus sativus</i> L.)

Saffron ( Crocus sativus L., Iridaceae) is a highly valued species in the food, medicinal, and nutraceutical industries as a coloring, flavoring, and therapeutic agent. Its productivity and flower production vary depending on different factors, including fertilizer treatment. This study was conducted to evaluate the effects of inorganic (NK) fertilizer combined with organic matter in different plant densities as well as the influence of split foliar fertilizer application on flower yield of saffron. The performance of saffron plants revealed that the combined application of inorganic fertilizer NK and vegetal organic matter (1%) was generally better than the effect of foliar treatment. Treatment with split foliar fertilizers at the recommended optimal concentration prolonged the flowering period of saffron plants.

“…Crocin, picrocrocin and safranal are responsible for color, taste and odor of saffron, respectively (Lage and Cantrell, 2009;Srivastava et al, 2010). Hence, in addition to quantitative yield (flower or corms weight) (Koocheki et al, 2014;Khorramdel et al, 2015), qualitative yield (secondary metabolites content) is known as a crucial factor in successful saffron production (Omidi et al, 2009;Koocheki et al, 2016).…”

Saffron’s color, taste and odor result from the chemicals crocin, picrocrocin and safranal, respectively. Hence, in addition to quantitative yield, secondary metabolites content are known as crucial factors for a successful saffron production. Moreover, enhancing resources efficiency, especially water and nitrogen, is becoming increasingly important for agricultural improvement in arid and semi-arid regions. Thus, the effects of irrigation levels and corm planting on crocin, picrocrocin and safranal content, water use efficiency (WUE) as well as nitrogen use efficiency (NUE) of saffron were investigated as a two-year field experiment based on a randomized complete block design arranged in split-plot with three replicates. The irrigation levels (100, 75 and 50% of saffron water requirement) and corm planting pattern (50, 100, 200 and 300 corms m-2) were allocated to main and sub-plots, respectively. Based on the results, crocin and picrocrocin content increased with decreasing irrigation levels. The highest WUES (WUE based on dry stigma yield) was obtained when 50% of saffron water requirement was supplied. However, the lowest WUEC (WUE based on daughter corms yield) and NUEC (NUE based on daughter corms yield) were obtained when 50% of saffron water requirement was applied. Irrespective of irrigation levels, WUES, WUEC and NUEC increased with increasing the planting density. The results demonstrated that although relatively severe water stress increases WUES and secondary metabolites in saffron stigmas, it could decrease WUEC and NUEC through affecting daughter corm growth.

“…Specifically, the climatic conditions of these locations were desirable for the production of the saffron corm and other vegetative characteristics. Previous studies reported a 70% increase in saffron flowering when planted in soils with lighter consistency ( Aghhavani Shajari et al, 2015 ); however, an 18% increase was reported in saffron stigma yield when grown in sandy soil as compared with the heavy soil ( Khorramdel et al, 2015 ).…”

Agro-Climatic Suitability Evaluation for Saffron Production in Areas of Western Himalaya

et al. 2021

Saffron (Crocus sativus L.) is an expensive spice crop cultivated successfully in Iran, Afghanistan, India, Greece, Morocco, Spain, and Italy. The present study was conducted during the periods 2018–2019 and 2019–2020 to evaluate the morphological, yield and quality parameters of saffron in six different regions of non-traditional areas of the western Himalayas. The two experimental factors were “year” and “location.” The experiment was conducted using a factorial randomized block design with three replications. Yield attributes, viz., number of flowers, fresh flower yield, fresh stigma yield and dry stigma yield were significantly higher in location L3 compared to other geographical locations. Dry stigma yield in location L3 was higher by 50.0, 41.2, 33.3, 14.3, and 9.1% compared to locations L6, L5, L1, L4, and L2, respectively. These were characterized by the appropriate climatic conditions, viz., high altitude, sandy-loam texture of the soil, optimum temperature, lesser relative humidity and total rainfall, demonstrating that it is possible to cultivate this spice even in non-traditional areas of the western Himalaya. Positive correlations were established for stigma yield with increased altitude and lesser rainfall. Secondary metabolites viz., crocin and picrocrocin increased significantly with the increase in altitude; however, a reverse trend was recorded for safranal content. Total phenolics and flavonoids were significantly higher in the geographical location of Kinnaur, H.P. (L1) and Bharmour, H.P. (L4). In conclusion, the assessment of different geographical locations and soil types is particularly necessary to encourage saffron production and its qualitative traits. Based on current findings, saffron can be grown successfully in some non-traditional locations of the western Himalayan regions.
