This study aimed to determine the extent different of distribution of the axial sprinkler water as a method of irrigation, and the effect of this on the quantity and quality of potato plant production in different areas along the axis sprinkler in the sandy soil of Eloued region in Algeria. For this, we relied on a sample of data consisting of 150 observations distributed over 10 areas according to the length of the axis. statistically we used oneway-analysis of variance after ensuring its statistical validity. Accordingly, we concluded that despite the significant statistical significance of the difference in the distribution of irrigation water( and the time taken and flow strength) along the axis, the difference in the amount of water supplied in the tenth area (tail region) reached a maximum of 57,58 % relative to the reference area ( the fourth region), which recorded at 42,42 % of what the reference area obtained, and at least 21,60 % was obtained in the eighth area relative to the reference region, which obtained 78,40 % of what the reference area obtained. However, according to the tests of our study, this had no significant effect on the difference, quantity and quality of production along the radius at the 5 % level. In light of these results, we concluded that the productivity of the irrigation water component fundamentally differs between the areas along the axis, which means that this irrigation method is not economical in sandy soils.

أجريت هذه التجربة بكلية العلوم الطبيعية والحياتية جامعة الوادي سنة 2023 بهدف تحديد تأثير مياه الري المعالجة بالبلازما على نمو وإنبات نباتات أصناف. صممت التجربة باختيار 18 أصصاً لكل صنف، مقسمة إلى ست معاملات (بذور غير معاملة بالماء العادي، بذور معاملة بالماء العادي الجاف، بذور معاملة بالماء العادي الرطب، بذور غير معاملة بالماء المعالج، بذور معاملة بالماء الجاف العادي، ومعاملة البذور بالماء المعالج الرطب) بواقع ثلاث مكررات لكل معاملة. أظهرت النتائج المتحصل عليها أن المياه المعالجة بالبلازما لها تأثير واضح على الصفات المورفولوجية والفسيولوجية خلال مرحلتي الإنبات والنمو لصنفي فيتو هيستال وهابا فافا. وأدى إلى زيادة في القياسات الخضرية المختلفة والمعايير الكيميائية. وهذا يدل على أن المياه المعالجة بالبلازما لها فعالية نسبية في التأثير إيجابياً على نمو وإنبات نباتات Vicia faba L في صنفي Fito Histal وHaba Fava. Abstract: This experiment was conducted at the Faculty of Natural and Life Sciences, University of El Oued, in 2023, with the aim of determining the effect of plasma treated irrigation water on the growth and germination of Vicia faba L plants of the Fito Histal and Haba Fava varieties. The experiment was designed by selecting 18 pots for each variety, divided into six treatments (untreated seeds with regular water, treated seeds with dry regular water, treated seeds with wet regular water, untreated seeds with treated water, treated seeds with dry treated water, and treated seeds with wet treated water), with three replicates for each treatment. The results obtained showed that plasma-treated water had a clear effect on the morphological and physiological characteristics during the germination and growth stages of the Fito Histal and Haba Fava varieties. It led to an increase in various vegetative measurements and chemical criteria. This demonstrates that plasma-treated water has a relative effectiveness in positively affecting the growth and germination of Vicia faba L plants in both the Fito Histal and Haba Fava varieties.
Study of the nutritional value of seeds and leaves of some quinoa cultivars Chenopodium Quinoa Willd

The aim of this study is knowing some of the chemical properties of four quinoa plant varieties (white, red, black and V2). Where we focused on the chemical and nutritional compositions of the quinoa plant, and the changes are represented in the elements of nutritional value (compounds of primary metabolism, secondary metabolism and mineral content). In addition to determining electrical conductivity and acidity (pH). The results showed that white quinoa seeds are characterized by a high content of proteins compared to the other three varieties. The fat and carbohydrate content were better in red quinoa followed by black quinoa while V2 variety was the lowest content. Regarding the value of the mineral content, the content was somewhat weak for the four studied varieties, within the range of 3.5%. The results of the study on the leaves show that the mineral content is high in the range of 35%. Whereas the highest protein content was found in black quinoa leaves. The content of carbohydrates and fats was relatively high for the white quinoa, followed by the red quinoa. All of this is due to genetic factors related to the quality of seeds, plant morphology, the extent of their adaptation and tolerance to various stresses and the various influences of climatic factors.
