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.

Bernas SM, Fitriana M, Wijaya A, Fitri SNA. 2020. Effect of the seedling age and compost to the growth of palm date lulu (Phoenix Dactylifera L.) nursery and investigation of female seedling. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 199-207.Indonesia imported very high amount of date palm fruits about 9.99 million kg or US$ 13.18 M, because of that it is necessary to develop a research about date palm seedling nursery and investigation of female date, since this is a dioecious plant. The aim of this investigation was to find out characteristics of female date seedling and the effects of seedling age and compost on seedling growth. There were 2 steps in this research: the first was application of compost on seedling (without and plus compost treatments) and the age of seedling (15 and 30 days old) for transplanting into polybag, the growth ability of plant was monitored. The second step was transplanting seedling at 30 days old into pan for investigation female date, which 20 seedlings were planted in one pan and replicated 3 times.  Results showed that compost increased roots and leaves growth on seedling.  Transplanted at 30 days old seedling had the ability to grow about 95% compared to 15 days old was only 45%. It was found that female seedling was about 25% and the rest (75%) was male or sterile. It is needed further investigation on growing female seedling in the field and can it produce fruit.

<p>This study was carried out to investigate the effect of a dietary preparation of Birhi tamr (<em>Phoenix dactylifera</em> L.) on serum glucose levels and body weight in normal, diabetic insulin-treated and diabetic insulin-untreated rats. Diabetes was partially induced by intraperitoneal injection of streptozotocin (32.25 mg/kg). Thirty six male Sprague-Dawley rats (239 ± 8.4 g) were divided into two normal, two diabetic insulin-treated and two diabetic insulin-untreated groups. Each group was fed a diet containing either 0% or 10% tamr for six weeks. Fasting serum glucose levels were determined by enzymatic-calorimetric method using a standard kit procedure.Feeding 10% tamr did not show significant differences (P &gt; 0.05) in serum glucose levels in any of the normal and insulin-treated diabetic rats. Insulin-untreated diabetic rats fed 0% tamr or 10% tamr exhibited significantly (P &lt; 0.05) higher serum glucose levels (496 ± 81.6, 315 ± 61.1 mg/dl respectively) compared to normal (147 ± 5.3, 156 ± 7.6 mg/dl respectively) and insulin-treated diabetic rats (227 ± 17.6, 268± 18.9 mg/dl respectively). Feeding 10% tamr to insulin-untreated rats induced significant (P &lt; 0.05) reduction in this variable. The findings of the present study may provide support for the favourable effect of date palm fruits as tamr, on blood glucose in streptozotocin-diabetic rats. This effect cannot be simply explained on the basis of the macro-nutrient composition of tamr. However, due to the apparent effects of tamr on blood glucose in normal and insulin-treated and insulin-untreated diabetic rats, the possible presence of insulin-like substance in tamr may not be excluded. The mechanism of action of the blood glucose-lowering effect of tamr awaits further investigation.</p>
