The earliest evidence suggesting the human utilisation of wild date palm fruits in the Near East is dated to the sixth and fifth millennia B.C. Despite the lack of archaeological data, it is commonly believed that at the end of the Late Uruk period (c. 3300–3100 B.C.) the Sumerians established the first date palm plantations. Nevertheless, this belief has never been well-proven by any scientific data, which makes this issue open to debate. This article points to the images of the date palm known from the pictographic script from Uruk as an important source of botanical data—a concept which has never been discussed in the literature—and elaborates on the phenotypic traits of the Phoenix dactylifera L. discernible there. It aims to establish the level and condition of horticultural knowledge of the cultivators of the date palm tree in the late fourth millennium B.C.Many of the botanical traits found on the date palm pictographs are noteworthy, especially where the morphology of the crown, trunk, and root zone are concerned. Most importantly, the identification of pictographs representing date palm inflorescences prompts us to the conclusion that the Sumerians discovered the dioecious nature of the Phoenix dactylifera L., selecting the staminate inflorescences to pollinate female trees by at least c. 3300 B.C. The discovery of this method of artificial fertilization was a turning point in Mesopotamian agriculture since it enabled farmers to obtain a better crop while economizing on space and labour, constituting the beginning of the date palm plantations that are still such a feature of present-day Iraq.

This research was conducted in orchard belong to Al-Mahawel date palm station (Abo Sderah) / Ministry of Agriculture located in governorate of Babylon, during the season 2015-2016. Twenty four uniform date palm Phoenix dactylifera. L. Sultani cultivar were used , to study the effect of the pollinator type(P1: Ghannamiakhder , P2: Ghannamiahmer and P3:khukri ), the concentration of Naphthalene Acetic Acid NAA(0 , 50 and 100 ) mg.L-1 and their interaction on fruits setting up , fruits drop and some of physical and chemical characteristics of fruits of date palm Sultani cultivar .Experiment carried out as factorial experiment(3×3) by Randomized Complete Block Design (RCBD) with three replications in each treatment , and the means were compared using LSD level of significant test at P ≤ 0·05. The results can be summarized as that Ghannamiahmer (P2)cultivar and 50 mg.L-1 NAA application showed a significant increase in the fruit setting% , while Khukri cultivar(P3) showed significantly increased fruit size and weight as compared with the other cultivars.Furthermore the cultivar(P1) obtained a significant increase in the bunch weight in Rutab stage as compared with the other cultivars. While the cultivar (P2) with 100 mg.L-1 NAA application showed significant increase in bunch weight in Rutab stage as compared with the other interactions. Ghannamiakhder (P1) cultivar had a significant increase in the fruit content of reducing sugars and non-reducing sugars, while khukri showed significant increase in fruit content of dry matter% and total sugars as compared with the other cultivars.
