Increasing fresh water shortage has revealed the use of waste water in agricultural irrigation, deficit irrigation approaches and integrated management of soil moisture with tillage-sowing practices. The crop productivity in the irrigated conditions is directly controlled by photosynthetic activities. Therefore, the effects of the irrigation with recycled domestic waste water at different irrigation water levels (100%, 67% and 33%), compared to full irrigated fresh water, on the chlorophyll content of silage maize and surface soil moisture in conventional tillage and direct sowing conditions were examined in the irrigation periods of two experimental years (2020 and 2021). The soil moisture was determined by 1.5% higher in direct sowing than in conventional tillage, and the chlorophyll content in full irrigation with waste water and the direct sowing was found by 4.9% and 1.9% higher than in full irrigation with fresh water and conventional tillage, respectively. However, chlorophyll content decreased by 20.7% and 34.0% at 33% and 67% deficit irrigation with waste water compared to full irrigation with waste water. The significant (p<0.01) linear correlation between the soil moisture and chlorophyll content showed that chlorophyll content can be managed with the soil moisture. It can have concluded that full irrigation with waste water in the direct sowing can be recommended with positive effects on the conservation of fresh water resources, effective managing soil moisture, thus saving irrigation water, increasing chlorophyll content and crop productivity.

The effects of heat stress on malondialdehid (MDA) content, ascorbic acid (AsA), isoperoxidases, total soluble protein (TSP) and SDS-PAGE protein profiles of small reddish bean (Phaseolus vulgaris L. cv. Keklik) leaves were investigated. For this purpose, the collected leaf samples (preferably the third from the apex) were placed into pyrex tubes with caps closed and incubated in a water bath: after a 30-minutes habituation at 30ºC, to apply heat stress the leaves were subjected to 35, 40, 45, 50, 55 and 60°C with gradual increments every 30-minutes. According to the results, the MDA content increased with escalating temperatures, starting with 40°C. Although there was fluctuation, the AsA content generally decreased with high temperatures. Besides, TSP content decreased after 50°C. Moreover, three asidic and four basic isoperoxidase bands were identified. There was a marked difference at acidic isoperoxidase band intensities under 40 and 45°C heat treatment. Protein bands with molecu1ar weight of approximately 14.5-195 kDa were determined. In conclusion, especially 40°C is critical for small reddish bean plants, besides 40°C and above temperatures causes oxidative stress in small reddish bean plant. Additionally, isoperoxidases and proteins may be an effective mean on heat stress tolerance.

Elderberry species (Sambucus spp.) grows mostly in wild form in the northern hemisphere. It is often used for landscaping riverbanks, as a windbreak, but also for human nutrition and medicinal purposes. This plant is used especially in the industrial field to obtain essence. In this study, the effects of some applications on rooting success in elder wood cuttings were investigated. For this purpose, in addition to 0, 2000, 4000 ppm IBA solution, a mixture solution of different Bacillus species (1.7X108 cfu/ml) was used. After the above-mentioned applications were applied to the wood cuttings taken from the plants during the resting period, they were taken into the perlite environment in the greenhouse at 22 0C. According to the results obtained, the number of roots per cutting was found to be between 11.3-22.4. Root lengths varied between 7.1-8.4 mm according to the applications. 2000 ppm IBA application was the application that increased both root length and root number the most. The study revealed that the rooting efficiency of black elderberry plant would be increased by IBA application.

Vegetables are the most important source of nitrate in the human diet. The nitrate content is not the same in the plant. Depending on the amount of nitrites, plant organs can be classified as follows: leaf (the largest amount) stem, inflorescence root, tuber, fruit. One of the most important factors in determining the quality of vegetable products is the content of nitrates and nitrites and the maximum permitted limits play an important role in human health. It is well known that a high dietary intake of nitrates and nitrites may increase the risk of gastrointestinal cancer due to the formation of carcinogenic chemicals known as N-nitroso compounds and the appearance in newborns of blue child syndrome. This study assessed the concentrations of nitrates and nitrates in 5 varieties of tomatoes from organic and the same 5 varieties from classical crops. The study showed that the amount of nitrates and nitrites in the tomato varieties taken in the studio was within the limits according to the legislation in force.

The study was conducted to determine the presence of indole-3-acetic acid (IAA) in PGPR isolates using PCR reactions and biochemical tests. Positive isolates were tested under in-vitro conditions for germination efficiency on maize (Zea mays L.) seeds. Salkowski method was used for IAA tests on 30 bacterial isolates with PGPR properties. The KH14.3 and KH24.1.2 isolates were biochemically active in terms of IAA test. The absorbance readings were made at 595 nm using microplate reader and resultant values were compared to an IAA standard. IAA production of isolates varied between 0.42-6.37 μg/ml. For germination experiments, 20 maize seeds were coated with IAA- positive isolates (1.3x107 cfu/ml) in petri dishes in triplicates according to the randomized plot design. The germination test was monitored for 7 days in an incubator at 25°C. Experimental data were subjected to analysis of variance (one-way ANOVA). The difference between the bacterial coating and control group was significant at the level of P≤0.05. Germination efficiency was determined as 99.9% for KH14.3 and 2.7% for KH24.1.2. Present findings revealed that KH14.3 was ACC deaminase, phosphatase, and siderophore-positive and KH24.1.2 was positive for ACC deaminase and phosphatase. These two isolates were also biochemically active in terms of IAA and could increase germination success by coating on seeds.

The study was carried out to determine whether different concentrations of essential oil components (geraniol, carvacrol, thymol, and alpha terpinene) and essential oil of thyme (Thymus vulgare) have any allelopathic effects on the germination of barley seeds. The study was carried out in the laboratory environment according to the divided plots experimental design in random plots. At the end of the experiment, the effects of allelochemical types of carvacrol, thymol and geraniol doses on germination rate and seedling dry weight were found to be statistically significant (p<0.01). It was determined that geraniol (0.00245 g), carvacrol (0.01790 g) and thymol (0.02590 g) had the most negative effects on seedling dry weight, respectively. As a result, it was determined that some of the herbal allelochemicals used were effective on the germination of barley seed and seedling growth, and the effect rate increased as the dose increased. Thymol, geraniol and carvacrol showed the most negative effects on the germination rate of barley seed at all doses. On the other hand, adverse effects were determined at high doses of alpha terpinene. All doses of thyme essential oil and low doses of alpha terpinene showed similar effects with the control. As a result; It is thought that essential oil components, which have a negative effect on the germination of barley seed, can be used in the production of plant-based bio-herbicides.

Just because of burning fossil fuels and the fact that renewable energy sources (solar, wind, hydraulic, geothermal, biomass, tidal, wave etc.) have not become widespread globally, many parallel environmental problems such as global warming, climate change and carbon emissions have been emerged. In the present study, two different orange cultivars (Valencia and Washington Navel) were dried under different air-convective conditions (50, 55 and 60°C). Samples were sliced three different thickness as 5, 7 and 9 mm, respectively. In addition, three different drying time was selected for orange drying as 8, 9 and 10 h, respectively. The effects of a single unit air convective drying of 1 kg product on greenhouse gas emissions (GGE) of different types of power plants (wind, solar, hydroelectric, and geothermal) were investigated. Present findings revealed that while the greatest GGE were obtained from the geothermal power plant, the lowest values were obtained from the wind power plant. Besides, increasing CO2 emissions were encountered with increasing drying time and sample thickness. Additionally, CO2 emissions had a decreasing trend at higher temperatures.

Algae produce some substances that have a positive effect on human health. Algae are known as sources suitable for use in food and foods with the bioactive components they produce at a high rate. These ingredients are called nutraceuticals. Nutraceuticals are products that have physiological benefits and are protective against chronic diseases and are generally recommended to be used as medicines. Bioactive nutraceuticals from aquaculture; fish oil (ω-3), seal blubber oil, algae oil, shark liver oil, shark cartilage, chitin, chitosan as well as enzymes, peptides and their components, vitamins (vitamin A,D,E, β carotene), macroalgae and its components, protein hydrolysates and other products. It is known that these high-value components in algae regulate immunity, prevent diabetes, oxidation, inflammation, high cholesterol and cardiovascular diseases, and have positive effects against obesity and unbalanced nutrition. In this review, information is given about micro and macroalgae-based nutraceuticals, their application areas and potential health benefits.

This work is part of the diversification of renewable energy sources such as biomass. The present research aims to concentrate on the valorization of desert date fruits, i.e. Balanites aegyptiaca. To the best of our knowledge, this plant has never been valorized in Algeria so far. For this, it was decided to choose one part of these fruits, namely the pulp, as a substrate for anaerobic fermentation for the production of bioethanol, which was shown to have a fairly significant added value. The results of the morphological analyses of the fruits of the desert palm indicated that the pulp represents 62.71% of the entire fruit, which is quite encouraging for the completion of the present work. It should be noted that the pulp is the most important ingredient in the fermentation process to produce alcohol. Moreover, the physicochemical characteristics of the raw material showed that the pulp of the fruits of the desert palm tree are rich in sugar, with 59.68% of total sugars and 34.18% of reducing sugars. Note also that these sugars are essential elements for alcoholic fermentation. The results obtained indicated that the optimal dilution of 1/4.4 (g / mL) gives 30% bioethanol (125 g of fruit gives 30 ml of bioethanol with 92° concentration).

Moreover, the physicochemical characteristics of the raw material showed that the pulp of the fruits of the desert palm tree are rich in sugar, with 59.68% of total sugars and 34.18% of reducing sugars. Note also that these sugars are essential elements for alcoholic fermentation. The results obtained indicated that the optimal dilution of 1/4.4 (g / mL) gives 30% bioethanol (125 g of fruit gives 30 ml of bioethanol with 92° concentration).","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125682089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study is interested in the pilot region of Djelfa steppe located in northern Algeria, where a sizable pastoral activity serves as the foundation of the social organisation and the primary source of income. Today's courses experience a severe degradation that menaces the future of pastoral activity due to the disorganisation of social fabric, the phenomenon of turning into a desert, and eolian erosion. It is in this concern that we worked out a methodological approach aiming at characterising the current ecological situation, by using efficient tools namely: remote sensing and GIS. Thus a card of occupation of the ground containing a characterisation of the various courses of the area was carried out by the use of the Landsat imagery. The results so obtained and other inherent data in the middle of study and with our problems were integrated in a Database with the purpose of placing at the disposal of the decision makers and the specialist’s rational management tools in the fodder resources.
