تأثير المعاملة بالأحماض العضوية في بعض خصائص النمو والإنتاجية لعدة أصناف من الزعفران البري والمزروع (L. Croccus sp)

Abstract

The research was carried out in Harisoun village, Baniyas region, during the agricultural season 2022/2023 to study the effect of treatment with organic acids (humic and fulvic) at concentrations (0, 25 and 50 mg/L) on the growth and productivity characteristics of saffron plants. Saffron bulbs (Iranian-Spanish-Abu Riha-Safrawi) were planted according to a complete randomized block design with three replicates. Some morphological traits were measured (leaf length (cm), number of leaves (leaf/plant), productivity (number of bulbs per plant (bulb/plant), weight of bulbs per plant (g), number of flowers per plant (flower/plant), and weight of dry stigmas (g). The results showed the positive effect of the treatment with organic acids at a concentration of (50 mg/L), as it outperformed the control treatment and the treatment (25 mg/L) in all the studied traits and characteristics for all varieties. The Spanish variety plants treated at a concentration of (50 mg/L) also outperformed in each of the traits (leaf length, number of bulbs/plant, weight of bulbs (g)), and reached (49.78 cm - 4.9 bulbs/plant - 51.01 g), respectively), while the plants of the wild variety Abu Riha treated at a concentration of (50 mg/L) outperformed in each of the following characteristics (number of leaves/plant, number of flowers/plant), and reached Respectively (8.44 leaves/plant 3.77 flowers/plant) and the treatment (50 mg/L) gave the highest dry stigma weight in Iranian saffron, which reached (0.0132 g), so we recommend using the concentration (50 mg/L) to treat saffron with organic acids during irrigation during the growing season.
