The effect of different types of fertilizers on plant growth and yield and nutritional value of zucchini

A factorial experiment was carried out using Randomized Completely Block Design (RCBD) with two factors and three replicates. The first factor was compound fertilizer with three levels symbolized by B۰, B۱, B۲, (۳۰۰, ۲۰۰, ۰ kg ha).-۱) The second factor is nano fertilizer with four levels and is symbolized by (C۰, C۱, C۲, C۳) (۳, ۲, ۱, ۰ g/L)-۱. The averages of the treatments were compared according to Duncan’s test at a probability level of ۰.۰۵. Each treatment was repeated three times and the results showed the following: -۱ The compound fertilizer (B۲) was significantly superior to treatments B۰ and B۱ in most of the vegetative growth and yield characteristics, as it gave an average leaf area of ۱۱۹.۰۴ cm.۲.paper-۱The total chlorophyll content of the leaves is ۴۷.۳۹۰۸ mg/۱۰۰ g.-۱The percentage of nutrients in the fruits was ۱.۷۵۰۸% nitrogen, ۰.۳۸۵۰% phosphorus, and ۳.۰۳۸۳% potassium. ۲- The C۳ nano fertilizer treatment significantly outperformed the percentage of nutrients in the fruits, as the nitrogen percentage reached ۱.۷۷۳۳%, the phosphorus percentage reached ۰.۴۷۰۰%, and the potassium percentage reached ۲.۸۲۶۷%. ۳- The interaction between compound fertilizer and nano fertilizer in treatment B۲C۳ was significantly superior to all treatments in all quantitative yield characteristics, as the percentage of nitrogen in the fruits reached ۲.۰۳۰۰%, the percentage of phosphorus reached ۰.۴۷۰۰%, and the percentage of potassium reached ۳.۷۲۳۳%.
