THE EFFECT OF BLACK TEA RESIDUES ON THE GROWTH OF Vicia faba AND SOME OF ITS PHENOTYPIC PROPERTIES AND CHEMICAL CONTENT OF CHLOROPHYLL

The current study was piloted at the College of Education for Girls-University of Kufa in during from (5-10-2018) to (15-2-2019) to studying the impact of black tea residues on some of the vegetative indicators of pea plants represented through (plant height, number of leaves, number of branches, length of branches, the leafy area and the soft weight of the vegetative group, the soft weight of the root system, the length of the root system, the length of the vegetative group as well as the total content of chlorophyll was measured (by adding three levels of black tea waste and it was as follows (240 g) and (180 g) 120 clouded to the seedlings of the above plant, and the rest of the seedlings were left without addition for the purpose of comparison. The results of the research appeared that the treatment exceeded (240 g) morally over each (control) and (120 g) treatments in all studied traits. While no significant difference was observed between the two treatments (240 g) and (180 g) in all the following characteristics (plant height, number of branches, length of branches), the treatment (240 g) exceeded all treatments in the (leafy area) recipe (Number of sheets). Likewise, no significant difference was observed between (120 g) and control treatment in all studied traits except in two traits (leafy area and number of plant leaves). The treatment also exceeded (180 g) for all of the (120 g) and (control) treatments in all the studied traits except for the adjective (paper area) in which no significant difference was observed between the treatment (180 g) and the treatment (120 g) , meaning that the treatment (180 g) Cloud overtook control treatment in all studied traits. The results of the research appeared the superiority of the treatment (240 g) of black tea waste in all the mentioned characteristics except for the characteristic (root length), where no significant difference was observed between the treatment (240 g) and the treatment (180 g). Also, the treatment (180 g) was superior to the treatment of (120 g) and (control) in all traits, as no significant difference was observed between the treatment (120 g) and the (control) treatment except in the characteristic (length of the vegetative group) where the treatment excelled (120) clouded control treatment of pea seedlings.
