To improve general appearance and quality of jujube fruit (Zizyphus mauriti-ana Lamk) cv Umran, NAA at 0, 5, 10 and 20 ppm was sprayed at fruit set stage. None of the treatments of NAA affected fruit size during stages 1 and II. However, 10 ppm NAA caused faster growth in the beginning of stage III resulting into a large sized and heavier fruits and stone as well. Similarly, the highest increase in total sugars and reducing sugars were recorded with 10 ppm NAA. However, the total soluble solids increased significantly with 5 and 10 ppm NAA whereas ascorbic acid content of the fruits were higher with 20 and 5 ppm NAA respectively. NAA sprays did not enhance or delay the fruit ripening.
