Impact of Foliar Application of Nano Organic (Optimus Plus) on Quantitative and Qualitative Traits of Two Potato (Solanum tuberosum L.) Cultivars

Abstract

College of Agriculture and Forestry, located within the university campus. The study involved two factors: the first was the application of an organic nutrient)Optimus Plus) at three concentrations (0, 2, and 4 ml L⁻¹), and the second included two imported potato cultivars, Lady Rosetta and Hermes. To promote growth, fertilizers were applied in three split doses: the first, 15 days after planting, included the full dose of phosphorus fertilizer; the second, at emergence, included half of the nitrogen and the full dose of potassium; and the third, one month after the second. Data were statistically analyzed using the SAS(2017)  software package [1] according to the experimental design, and treatment means were compared using Duncan’s Multiple Range Test at a significance level of ≤0.05.
