Effect Of Adding Polymer (Sap) Levels, Spraying Kaolin Anti-Transpiration, And Bread Yeast Suspension On Some Qualitative Traits In Fruits Of Carica Papaya L.

Abstract

The experiment was conducted at the research station of the College of Agriculture and Marshes, Thi-Qar University, on papaya plants during the growing season 2021 in order to know the effect of adding different levels of SAP agricultural polymer, which are (0, 50, 100) g.m^-2. Kaolin  anti-transpiration levels (0, 1, 3) g.L^-1 and baking yeast with two levels (0, 20) g.L^-1  in some qualitative traits in papaya fruits, A complete random block design with three replicates was used to bring the number of experimental units to 54 experimental units. It is clear from the results that the polymer addition treatment excelled to 100 g.m^-2.The treatment of anti-transpiration 3 g.L^-1 and yeast spray 20 g.L^-1 had the highest percentage of protein, vitamin C and carotene pigment in papaya fruits, while it was the lowest value when the control treatment.
