Abstract
This study was conducted in one of the nurseries, Al-Sharqat district for the season 2023-2024 to study the effect of methods of adding humic acid (without adding acid to the soil and spraying on the plant) on the yield of different varieties of beans, namely (local, Dutch, Spanish and French). The treatment of adding acid to the soil significantly affected the characteristics of the yield, including the number of pods plant-1, seed weight g, seed yield plant-1 and biological yield, with an increase of 60%, 74.24%, 15.62 and 14.85% respectively compared to the control treatment. The French variety excelled in the characteristics of counting pods by 60% compared to the local variety, while the local variety outperformed in the seed weight characteristic by 74.24% and compared to the French variety, and also outperformed in seed yield and biological yield by 42.86% 42.86% respectively compared to the Dutch variety. The same variety outperformed with acid and without acid with the highest number of pods plant-1 amounted to 8.0 pods-1 and an increase of 60% compared to the local variety with acid and without acid, which gave the lowest number Of the pods, 5 pods were 1, while the local variety to which acid was added outweighed the highest weight per seed was 1.17 g compared to the French variety that is not treated with acid, whose seed weight reached 0.65 g, and the same variety excelled in seed yield, plant-1 and biological yield, with an increase of 69.13 and 36.59% compared to the Dutch and Spanish varieties.
