Response Growth and Yield of Three Cucumber Hybrids (Cucumis sativus L.) to Nano Fertilizer N20P20K20 under Protected House

Abstract

The experiment was run in the spring of 2021 in one of the unheated plastic houses in the Department of Horticulture and Landscape in the College of Agriculture and Forestry at the University of Mosul to examine the impact of two variables: Second: spraying three different concentrations of Nano fertilizer N20 P20 K20 on three different cucumber hybrids (Roni, Modhish, and Baher) alongside a control treatment that received no Nano fertilizer spraying. The hybrid factor was positioned in the main plots, and Nano-fertilizer spray concentrations were positioned in the split plots, all within the context of a Randomized Complete Block Design (RCBD) for the experiment’s layout. The information was recorded, then analyzed statistically, yielding the following findings: Concentrations of 3 mg L-1 of Nano fertilizer sprayed on Roni hybrids significantly increased plant length and leaf area; concentrations of 3 mg L-1 on Modhish hybrids significantly increased yield per plant, fruit yield, and total fruit yield; and concentrations of 3 mg L-1 on Baher hybrids significantly increased the value of leaves per plant.
