EFFECT OF ADDING PHOSPHORUS AND SPRAYING WITH ZINC IN THE VEGETATIVE GROWTH AND YIELD OF CABBAGE PLANTS

Abstract

This study was conducted at the Experimental Research Station in the College of Agricultural Engineering/University of Baghdad in the Jadiriyah area during the fall season of 2022. The study aimed to find out the effect of adding phosphorus and spray with zinc in the vegetative growth and yield of cabbage plants. The experiment included two factors: the first factor was phosphorus (P) at four concentrations (P25%, P50%, P75%, and P100% of the recommended complete fertilizer dose of 135 kg P2O5 per hectare), and the second factor was spray with zinc sulfate (ZnSO4) at three concentrations (0, 30, and 60 mg/L). which symbolize it as (Z0, Z1, Z2) respectively the results showed that the treatment P75 Z2 significantly influenced most of the study's parameters, such as plant height, number of outer and inner leaves, leaf area, dry weight, and plant productivity, with values of 23 cm, 17.30 leaves, 71.67 leaves, 939.53 cm2, 12.84%, and 2.33 kg, respectively, compared to the control treatment.
