Effect of Foliar Application of Nano-Fertilizer NPK and Yeast Suspension on some Chemical Properties of Leaves and Fruits of Eggplant Solanum melongena L.

Abstract

The experiment was conducted in the season (2020-2021) in one of the greenhouses in the second research station of the College of Agriculture at the University of Al-Muthanna, this study was carried out to find out the effect of adding yeast fodder at three concentrations (0, 5.0, 10.0 gL−1) as well as nano fertilizer at three concentrations as well (0, 0.5, 1.0 ml L−1). Where this experiment was conducted on eggplant planted in greenhouses, the irrigation system in these houses was drip irrigation technology, the experiment was carried out with three random replications (complete plots). The results had a significant positive effect for both yeast and nano fertilizer, as well as a positive effect at the interaction between them and in all chemical properties and for each of the leaves and fruits of the eggplant plant (content of nitrogen, phosphorous and chlorophyll in leaves, proteins and carbohydrates in eggplant, fruits and dry weight of the plant). The leaves content of nitrogen, phosphorous, protein and carbohydrates (5.678%, 0.454%, 35.48%, & 61.00 gm 100 gm−1) dry weight, respectively.
