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.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130931906","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}

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.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116481452","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}

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.","PeriodicalId":254664,"journal":{"name":"Current Trends in Natural Sciences","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126842530","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 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.

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).","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}
