Enhancing Fruit and True Seed Production in Potato (Solanum tuberosum L.) Through Amino Acid Foliar Application: A Comparative Study of Naima and Eclat Cultivars

Abstract

This research was conducted in Ram Hamdan area, which belongs to Idlib Governorate, during the 2023-2024 agricultural season, as this area is considered one of the most important potato cultivation areas in the governorate. The study used two potato cultivars, Naima and Eclat, which are widely spread in the study area, where plants were sprayed with amino acid solutions at concentrations of 0, 10, and 20 g/L, at a rate of one spray every 15 days after plant emergence above soil surface until flowering time. The experiment depended on completely randomized design (CRD).Results showed superiority of Naima cultivar over Eclat cultivar in traits of leaf area (196.3 cm²), days to flowering (43.6 days), fruit weight (5.94 g), number of true seeds per fruit (181.75 seeds/fruit), while Eclat cultivar surpassed Naima cultivar in traits of total number of flowers per plant (59.62 flowers/plant), total number of fruits per plant (22.2 fruits/plant), fruit yield per plant (97.07 g/plant), true seed yield per plant (2.01 g), true seed yield per hectare (80.7 kg/ha), with no significant differences between the two cultivars in true seed germination percentage (overall average 67.24%).On the other hand, amino acid spray treatments significantly outperformed the control treatment in all studied traits. The lowest concentration (10 g/L) achieved significant superiority over the control (0 g/L) in traits of leaf area (196.6 cm²), days to flowering (43.3 days), number of flowers per plant (55.98 flowers/plant), number of fruits per plant (21.5 fruits/plant), fruit weight (5.29 g), fruit yield per plant (110.7 g/plant), number of true seeds per fruit (165.7 seeds/fruit), true seed yield per plant (1.92 g/plant), true seed yield per hectare (7.68 kg/ha), and seed germination percentage (69.1%).Finally, the concentration (20 g/L) achieved significant superiority over the concentration (10 g/L) in traits of total number of flowers per plant (59.01 flowers/plant), single fruit weight (5.75 g), and number of true seeds per fruit (193.23 seeds/fruit), while there was no significant effect of increasing spray concentration on improving the rest of the traits studied.
