The present work on the cultivation of winter vegetable species, which was carried out in the perimeters of development of the six communes of the region of Ouargla. We found that the biodiversity recorded is 16 species and 09 botanical families, during the study period. The most frequent botanical families are : Liliaceae (Allium cepa L.), Chenopodiaceae (Spinacia oleracea.), Asteraceae (Lactuca sativa) and Apiaceae (Daucus carota .). Many local cultivars have been identified; their identification is mainly based on: the origin of the seeds, the shape and color of the fruits. According to the average richness and diversity index calculations, we found that the stations of Sidi Khouiled and Hassi Ben Abdallah have a great diversity, unlike Rouissat and Ouargla where the diversity is low. The local diversity seems to be threatened, this is due to several causes among others the non-reasoned selection of local cultivars and the introduction of hybrid seeds which allows us to validate the first hypothesis that says (the development projects have favored the introduction of many new vegetable species, not traditionally cultivated in the areas and have favored the use of hybrid varieties, with high production potential. This policy induces a genetic erosion, especially for local cultivars) and to reject the second hypothesis that says (the development perimeters participate in the preservation of local cultivars, which ensures their sustainability in the medium and long term).

Urban green spaces are essential to assuring the quality of life. This study aims to study the diversity of plant communities associated with urban green spaces in southwestern Algeria. Based on data collected from 57 phytoecological surveys with an area of 1 m², plant communities were analyzed using diversity parameters (specific richness, biodiversity indices and similarity) and plant functional traits (life forms, morphological, phytogeographical and dispersal types). 32 species belonging to 31 genera in 13 families have been identified. According to the real spectrum (data based on abundance) of plant functional traits, plant species are mainly geophytes (48.27%) which adopt various dispersal strategies, including barochores (71.55%) and anemochores (17.24%). Phytogeographic analysis revealed the dominance of the cosmopolitan element (41.55%) which is well adapted to the Saharan climate. Agglomerative hierarchical clustering of species based on their abundance by Minitab 17 revealed six groups. This work provides important information that can serve as a basis for the management and conservation of biodiversity in southwestern Algeria.

The field experiments were carried out at Buno Bedele and Omonada Jimma Zones on farmers’ fields for three consecutive main seasons and two sites each. The 10 treatments were laid down in a randomized complete block design (RCBD) with three replications using (BH661) hybrid maize variety. All across season and location data analysis of ANNOVA showed that all parameters were significantly affected by different time of nitrogen applications including plant height, grain yield, and harvest index, above ground biomass and logging percentage. The two highest grain yield 6.48 and 6.47 was recorded from applying 1/3 at planting + 2/3 at flag leaf appearance stage and applying 1/2 at planting + 1/2 at 4-5 weeks after emerge (Positive control) respectively again this treatment gave 13.08 and 12.62 t ha-1 above ground biomass yield respectively. The highest grain yield has 78.24 and 23.00 % yield advantage over negative control and applying all recommended N rate at planting respectively. Again in economic analysis, the above treatments gave the highest 111660 and 111840 net benefit respectively. Even though the applying 1/3 at planting + 2/3 at flag leaf appearance treatment MMR was not acceptable. Therefore, based on the highest net benefit applying 1/2 at planting + 1/2 at 4-5 weeks after emerge (Positive control) and applying 1/3 at planting + 2/3 at flag leaf appearance nitrogen fertilizer split application on late maturing (BH661) maize variety give an economic yield response and also acceptable for farmers of study areas and similar agro ecology.

The soils of Algeria are generally poor in nitrogen and always pose the problem of the availability of available phosphorus especially in arid regions, where there is also the problem of salinity which is often accompanied by the presence of limestone. The present work aims to examine the optimization of phospho-nitrogen fertilization on a durum wheat crop in saline and carbonate conditions through the use of different types, forms and doses of nitrogen and phosphate fertilizers. The fertilizers used are: Urea(46%), triple super phosphate TSP(46%), simple super phosphate SSP(20%), Potassium Nitrate KNO3(13%), Monammonium phosphate MAP(12%, 61%), NPK(15%,15%,15%), NPK(20%,20%,20%), NPK(13%,40%,13%), NPK(30%,10%,10%), NPK(4%,20%,25%), combined with three doses (D1=150U N and P ha-1, D2=200U N and P ha-1 and D3=250U N and P ha-1). The results obtained show that phospho-nitrogen fertilization has a very important effect on the parameters studied. Indeed, we notice that the best results are obtained by compound fertilizers, height of the plants: (HP) =MAP and NPK(15%,15%,15%) (250U ha-1) and (KNO3-SSP) (150U ha-1), yield and its components: Number of grains ear-1 (NG E-1) =NPK(13%,40%,13%) (250U ha-1), 1000 grains weight (TGW) =NPK(4%,20%,25%) (250U ha-1), grain Yield (GY) =NPK(13%,40%,13%) (250U ha-1) and NPK(15%,15%,15%) (150U/ha), straw yield (SY) =NPK(15%,15%,15%) (250U ha-1) and (KNO3-SSP) (150U ha-1). However the highest nitrogen and phosphorus content of the grains is obtained by simples fertilizers, N= (Urea-SSP) with the dose (200 and 250 U ha-1), and P = (Urea-TSP) with the dose (150U ha-1). It is noted that the NPK(15%,15%,15%) fertilizer was able to give better grain and straw yields with the lowest dose as well as obtaining the best plant height and better straw yield with the lowest dose of (KNO3-SSP) fertilizer.

Field experiments were carried out for 2018-2020 main cropping seasons at kersa and Omonada Jimma on farmers’ fields. The treatments consisted of factorial combinations of 23/23, 23/46, 46/46 and 69/69 NP kg ha-1 levels with inter and intra (333333, 250000, 200000 and 166667 plant density ha-1) respectively laid down in a randomized complete block design (RCBD) with three replications using (Nassir) common bean variety. Across season and location data analysis of ANNOVA showed that all parameters were significantly affected by different densities and NP fertilizer rates including above ground biomass, harvest index and grain yield except harvest index was not affected by NP fertilizer rates. The highest plant height (72.51cm) was recorded from the highest (69/69 kg ha-1) NP fertilizer rate. The highest above ground biomass and grain yield of 6.40 and 2.45 t ha-1 were obtained from the highest (333333) plant density ha-1. Also, it showed still there was an increase in plant density increases with 26.29 and 6.52% grain yield advantage over the lowest density and control recommendation respectively. Also from economic and sensitivity analysis results treatments (333333) ha-1 plant population density, (23/23) and (46/46) kg/ha NP fertilizer rates gave the highest yield response and net benefit with MMR 1035, 111 and 224% respectively. In conclusion, intra and inter row spacing 3*10cm or equivalent (333333) ha-1 plant population density with applications of one of the two (23-23) or (46/46) kg/ha NP fertilizer rates based on their resource was recommended to farmers of study areas and similar agro ecology.

The Northern Sahara Aquifer System (NSAS) is a complex system that includes several aquifers overlying most areas. The Continental Intercalary, also known as the "Albian groundwater" is an aquifer with impressive characteristics. It extends over three countries: Algeria, Tunisia and Libya. Intended for crop irrigation, the boreholes drilled in this Algerian aquifer, the boreholes carried out on this aquifer are artesian in their totality, with flows and pressures reaching in some places considerable values, of the order of 0,4 m3.s-1 for the flow and 3.106 Pa for the pressure. These two parameters are necessary to appreciate the energy potential of the Albian groundwater. A survey of the Continental Intercalary was carried out to study its energy potential. We were able to gather all possible data concerning the boreholes in the Algerian aquifer part. The study covered 295 boreholes that were identified and well documented, spread over 3 regions in southern Algeria. The water from the artesian boreholes in the Albian groundwater is transported to storage basins (for drinking water supply, irrigation and industry) for later use, or distributed directly to users after lowering the temperature of the water in the cooling towers. In these operations, all the hydraulic energy is lost and external energy is required from the electricity grid to meet the needs. The cumulative energy potential of all the boreholes identified has reached the theoretical value of 168GWh/year, the equivalent of 14520 toe (ton of oil equivalent) that are lost annually. Best management of this natural resource will not only enable resilient and sustainable management of the production systems and the environment, but also the energy needed to cool the water, as well as the energy needed for the maintenance of the boreholes and the facilities in the direct neighbourhood.

This study aims to analyse date’s market functioning and constraints that are facing it in Southeast of Algeria, Ouargla region. To analyze potential market pathways (traders, collectors and intermediaries) 100 respondents were randomly selected. Descriptive statistical analysis has been applied to achieve the research’s gaols. Analysis confirms that, Ouargla does not have an organized date-palm market dedicated to dates only, and which is characterized by total anarchy mainly due to lack of improved and advanced management, regulation and a lot of intermediaries spread. Date’s marketing in this area of study is complex because it is a string composed of producers, collectors, storers and mandataries in upstream. However, packers, processors and exporters are in downstream, thus a stakeholder’s divergence is created, for varietie’s quality as well as destinations in the marketplace’s channels. Most of traders are at an economically active age. Therefore, they should be able to perform their marketing functions effectively. Date’s varieties that are sold in the area of study differ from trader to another which is depending on their availability customers, prices offered as well as operator’s financial capacity. Indeed, 46% of fresh dates are available in market during the full harvest period but unfortunately this coincides with local and external market’s saturation where imbalanced supply and demand induce lower date’s price. This study allows to identify main constraints of date’s sector marketing that hinder its efficiency, which are related to technical, professional, social - cultural and commercial environment as a result this sector’s market suffers from serious dysfunctions.

The aim of our work is to study the sustainability of seal and market gardening production systems. This study was carried out in two study areas N'goussa and Hassi Ben Abdellah in the region of Ouargla (Algeria), through 75 surveys in different farms where we elaborated a typology of evolution in order to know the determining elements of the trajectories. The Ouargla region's Farm Sustainability Indicator (IDEA) is important. The assessment of agro-ecological, socio-territorial and economic indicators indicates that the agro-ecological indicator is the most represented by (the indicator of fertilizer and agricultural practices) by 46 out of 100. The work was followed by statistical analyses (using Excel stat) to study sustainability constraints. The results show that the polyculture system (date palm, market gardening, etc.) is the most dynamic in terms of cultivation practices. The market gardening production system is economically profitable in the two study areas due to the evolution of market gardening under shelter. The stability of the seal farming system and its uniqueness indicate that it shows the most signs of sustainability.

Endophyte microorganisms have great biotechnological interest, with features applicable to different areas and are potentially useful in agriculture. In the current study, the most dominant and representative endophytic fungal species of seven halophytic plants prevalent in the southeastern Algeria, Touggourt, were screened for their ability to produce four extracellular enzymes namely: cellulase, amylase, laccase, and lipase. Zygophyllum album came first by hosting diverse endophytic species among all the tested plants with eight species followed by Tamarix boveana and Limoniastrum guyonianum (46.66%) as well as Phragmites communis with 40% and Haloxylon articulatum and Aeluropus littoralis with 33.33%. Unlike J. effusus, it was the less diverse plant where only three species (20%) were identified. In term of enzymatic activities of the selected fungi, the two species of Chaetomium presented cellulase, amylase and lipase activity. Unlike, Trichoderma harzianum involved in lipase, Ulocladium sp. in cellulase, Bipolaris sp. and Botryostimphylium sp. in Amylase. Unlike, the two species of Chaetomium involved in cellulase, amylase and lipase. On the other hand, no enzyme activity was recorded in the colonies of Fusarium sp.

The relationship between meat consumption and health is complex and should be analyzed in detail, paying particular attention to the relevant differences that characterize the effects of different types of meat, and in several studies on poultry meat, including turkey, which is characterized by its highly digestible proteins (with low levels of collagen), and of good nutritional quality as well as unsaturated fats (found mainly in the skin and easily removed) and vitamins of group B (mainly thiamine, vitamin B6, and pantothenic acid), Minerals (such as iron, zinc, and copper) make its meat a valuable food. Through this study, it was found that there is a relationship between the consumption of turkey meat within a balanced diet and good health. Consuming it as part of a diet rich in vegetables is associated with a reduced risk of weight gain, obesity, cardiovascular disease, and type 2 diabetes. White meat (and poultry in particular) is considered moderately protective or neutral against cancer risk. The importance of poultry meat to humans has also been recognized by the Food and Agriculture Organization of the United Nations (FAO), which considers this widely available and relatively inexpensive food to be particularly beneficial in developing countries, as it can help fill in the deficiency of essential nutrients. Consumption of Turkey also contributes to the overall quality of the diet at specific ages and conditions (before conception, during pregnancy until the end of breastfeeding, during growth, and into old age) and is suitable for those with an increased need for calories and protein compared to the general population. And it was found that turkey meat contains some vital amines, which are an indicator of quality, as well as having antioxidant and antibacterial activity, and it has been proven that eating this type of meat reduces the incidence of COVID-19 disease.

Abstract: It is important to understand the fruit insect interaction mechanism to developing strategies to control the pests. The Mediterranean fruit fly Ceratitis capitata (Medfly) infested some blueberries Vaccinium spp. cultivars, and their volatile compounds composition of infested fruit of those cultivars has been studied. Head space solid-phase microextraction extraction- gas chromatography (SPME-GC/MS) has been used to detect volatiles on these cultivars. First Blush 4514 and Brigitta 1403 Australian cultivars used in this experiment. A total of 119 compounds find form these cultivars. There are a major different volatiles and their structure from infested fruits. HS-SPME released complex volatiles including (butanoic acid-3 methyl-, methy ester, methyl isovalerate, Butanoic acid-3 methyl-, isobutyl acetate, ethanone,2,2-dihydroxy-phenyl ) from First blush and Styrene, and 6-Methyl 1-2,3-dihydro-1,4-oxathine, methyl isovalerate, butanoic acid-3 methyl-, methy ester, ethyl isobutenoate from Brigitta cultivar.
