Impact of Zinc Sulphate and Boric Acid Spraying on Production and Quality Characteristics of Potato Plants

An investigation was conducted in the vegetable field division of the College of Agriculture and Forestry’s Horticulture and Landscape Design at the University of Mosul throughout the spring growing season of 2023. The experimental design comprised two components. The initial component involved applying zinc sulphate sprays to the vegetative growth at three different concentrations (0, 1500, and 3000 mg l -1 ). The subsequent component involved applying boric acid sprays to the vegetative growth at three different concentrations (0, 200, and 400 mg l -1 ). The experiment was replicated three times, and at a 5% level of probability, the means were compared using Duncan’s multiple range test. The field experiment was conducted utilising a factorial design with a Randomised complete block design (RCBD). Plants subjected to treatment with zinc sulphate at a concentration of 1500 mg l -1 exhibited a substantial increase in the majority of the traits under investigation. Similarly, plants sprayed with boric acid at a concentration of 400 mg l -1 demonstrated a significant increase in the majority of the traits under study.
