The effect of spraying with zolfast on the chemical qualities of three hybrids of eggplant L. Solanum melongena growing under protected cultivation

Abstract

The study was conducted in the plastic House during the growing season 2021_2022 at the research station belonging to the Faculty of Agriculture and marshes / Dhi Qar University / mustafiya area in order to study the effect of spraying with Zolfast on the growth and yield of three hybrids of eggplants and the overlap between them under protected cultivation (plastic house ), and the varieties are (black ,Barcelona and black beauty), where they were treated with five concentrations are(0, 0.5, 1, 1.5 and 2)ml L1, and sprays five times in a row and every two weeks a spray, and its effect on the chemical qualities (the percentage of chlorophyll in the leaves, the estimation of anthocyanin pigment in the fruit peels and the estimation of alkaloids in the fruits) of the eggplant plant is studied. Use the design of complete random sectors (R.C.B.D) for a one-time split factor experiment, where the items are placed in the main pieces of the Main_Plot and the concentration of zolfast is the second factor of the Sup_Plot, where it was distributed to three repeaters for each item in one warehouse, thus the number of experimental units reached 45 units .
