Abstract Response of ‘Flame seedless’ grape cultivar to the foliar application of seaweed extract and folic and fulvic acids This study was performed during 2019 and 2003 seasons on seven years old ”Flame seedless” grape vines (Vitis vinefera L.). The vines were cultivated at 3 meters apart between rows and 2 meters between trees in the same row in a sandy loam soil under drip irrigation system in a private orchard located at EL-Nubaria, EL-Beheira Governorate, Egypt. They were sprayed three times, before flowering, during the full bloom and three weeks later with the following treatments: 1. Control spray with water only 2. Fulvic acid at 1000 ppm 3. Fulvic acid at 1500 ppm 4. Fulvic acid at 2000ppm 5. Folic acid (vitamin B9) at 100 ppm 6. Folic acid (vitamin B9) at 150 ppm 7. Folic acid (vitamin B9) at 200 ppm 8. Seaweed at 2000 ppm 9. Seaweed at 3000 ppm 10. Seaweed at 4000 ppm 11. Combination 1: 0333 ppm Fulvic acid + 100 ppm Folic acid (vitamin B9) + 2000 ppm Seaweed 12. Combination 2: 1500 ppm Fulvic acid + 150 ppm Folic acid (vitamin B9) + 3000 ppm Seaweed 13. Combination 3: 2000 ppm Fulvic acid + 200 ppm Folic acid (vitamin B9) + 4000 ppm Seaweed The previous applied treatments were arranged in a randomized complete block design with eight replicates for each treatment and one vine for each replicate The results of this experiment could be summarized as follows Spraying Fulvic acid at 1000, 1500 and 2000, Folic acid at 100, 150 and 200 ppm and Seaweed at 2000, 3000 and 4000 increased in general the vegetative growth attributes, yield, fruit chemical and physical characteristics and leaf mineral composition from N, P and K of ”Flame seedless” grape cultivar as compared to control in the two seasons. |
