Effect of Foliar Spray of Nano Nitrogen and Bread Yeast on some Vegetative Growth of Pepper Plants

Abstract

Abstract The College of Agriculture - Sumer University conducted a field experiment in 2019 to explore the effects of spraying pepper plants with nano-nitrogen and yeast extract on various vegetative features. Two variables’ effects were investigated in this experiment. Spraying pepper seedlings with three different concentrations of nano nitrogen (0, 2, 4 mlliter-1) and three different concentrations of yeast extract were the first two factors (0, 3, 6 g L-1). With three repetitions and nine experimental units per duplicate, the experiment was conducted in a fully randomized block design (RCBD). According to the findings, spraying with nano-nitrogen N2 resulted in a significant increase in the plant height and stem diameter, as well as an increase in leaf area and chlorophyll content in the leaves compared to the control treatment with N0. In contrast to spraying with yeast extract, the spraying treatment Y2 was more effective in terms of plant height and stem diameter, the number of leaves, leaf area, chlorophyll content in the leaves and percentages of N, P and K in the leaves than the control treatment Y0.
