The Influence of Salinity Levels of Irrigation Water and Spraying with Alphatocopherol on some Vegetative Qualities of Citrus Rangpur Origin (Citrus Limonia)

Abstract

Abstract On Dhi-Qar University’s Department of Horticulture and Garden Engineering used their Saran-covered plastic greenhouse during the 2022 growing season for an experiment. The experiment started on 15 \ 1\ 2022. The experiment was designed as a working experiment according to the design of complete randomized block Design (R.C.B.D, the experiment included two factors, the main factor was the stages of salinity of irrigation water (1, 2, 4) decimens. M-1 and the second agent is Tocopherol (0 a–, 150, 300 ) mg. L-1 is produced by the Indian company HIMEDIA with three repeaters. Important findings from the study included the fact that as saline levels in irrigation water increased, most of the attributes under investigation suffered considerable declines, especially the Level (4 decimens M-1), which gave the lowest rates in the qualities (plant height rate, stem diameter rate, branch number rate, leaf number rate, leaf area rate, soft weight rate of the vegetative total, dry weight rate of the vegetative total), as the measurements reached (60.24 CM. Plant-1, 5.51 mm Plant-1, 4.46 branches. Plant -1, 75.11 leaves. Plant -1, 965.00 cm2. Plant-1, 45.09 G. Plant-1, 15.45 G. Plant-1) respectively, as to add a – Tocopherol sprayed on the vegetative total has a positive moral effect and the treatment exceeded (300) mg. L-1 gave the highest measurements in the following characteristics (plant height rate, stem diameter rate, branch number rate, leaf number rate, leaf area rate, soft weight rate of the vegetative total, dry weight rate of the vegetative total), reaching (78.17 CM. Plant-1, 7.74 mm Plant-1, 7.58 branches. Plant -1, 88.04 leaves. Plant -1, 1661.33 cm2. Plant-1, 55.06 G. Plant-1, 19.44 G. Plant-1) respectively.
