Ethnobotanical study of medicinal plants used by the population at the province ofd’El Abiodh Sidi Cheikh (El Bayadh), Algeria
Our objective: This ethnobotanical study was conducted in the region of El Bioudh Sidi Cheikhe (El Bayadh, Algeria) to gather information on the phytotherapeutic uses practiced in this region. Using questionnaire sheets, a series of ethnobotanical surveys were carried out during the year 2023. The identification of plants collected in the field was carried out in the laboratory. We selected 46 species belonging to twenty-four (24) botanical families, and the list of different families and species of medicinal plants chosen is presented in Figure 1, along with their frequency of citation. The most commonly used family was Asteraceae (07 species) with a percentage of 15.21%, followed by Fabaceae, Solanaceae (04 species) with a percentage of 8.69%, and then Apiaceae, Lamiaceae, Poaceae (03 species) with a percentage of 6.52%. Caryophyllaceae, Tamaricaceae, Verbenaceae (02 species) followed with a percentage of 4.34%. Other families were represented by a single (01) species, each with a common percentage of 2.17%. The most commonly used plant parts (organs) were the leaves with a rate of 60.37%, followed by the seeds with a rate of 21.74%, and then the roots with a rate of 8.70%. The flowers and fruits had the same rate, which was 4.35%. Moreover, the diseases treated by these medicinal plants are dominated by digestive disorders (43.47%), skin disorders (13%), genitourinary disorders (15.21%), and neurological disorders (2.17%). The surveys carried out made it possible to inventory the medicinal species and to collect the maximum information concerning local traditional therapeutic uses. These results can be considered as a source of information for scientific research in the fields of phytochemistry and pharmacology.
Study the response of Mannitol and Nano Urea to mitigate the adverse effect of terminal heat stress on wheat (Triticum aestivum L.)
The present in investigation entitled “physiological study of wheat (Triticum aestivum L.) with foliar application of mannitol and nano urea under sodic soil condition” was conducted during Rabi season, 2022-23 at the student instructional farm (SIF) of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya- 224229 (U.P.). The experiment was conducted in Split Plot design with three replications, seven treatments and wheat variety (HD 2967). The treatment was comprised of control distilled water spray, Mannitol 25, 50, 100 ppm and Nano urea 25, 50, 100 ppm respectively, which was foliar sprayed at 30 DAS. The observations have been studied on growth, bio-chemical, yield and yield attributes of wheat. Observations were recorded at 60, 90 DAS and at maturity stages for timely sowing (15 November) and late sowing (15 December). However, yield and yield parameters were taken at the time of harvesting of the crop. Foliar spray of mannitol and nano urea were performed well at 60, 90 DAS and at maturity parameters. Foliar application of nano urea with 25 ppm was recorded superior on plant height (cm), dry weight plant-1 (g), chlorophyll content in leaves (SPAD value), Catalase activity (g-1 fresh weight min-1), Peroxidase activity (mg g-1 fresh weight min-1), Super oxide dismutase activity (mg g-1 fresh weight min-1) However, yield and yield attributes viz length of spike, number of tillers plant-1, number of grains spike-1, grain yield plant-1 It is concluded from the result that foliar spray of nano urea 25 ppm was found most effective to increasing all characters and yield parameters of wheat.
Agricultural mechanization trends and drivers in selected state of bringing Green Revolution to Eastern India
The current study analyzed trends and drivers that influence agricultural mechanization in Bihar state (one of the states selected to bring Green Revolution 2.0) of India. The interview schedule was administered to 800 respondents, selected proportionately from 4 agro-climatic zones to collect primary data. For the first time top 20 farm machinery used in Bihar is tried to be ranked. Data were analyzed by using a multinomial logit model which predicts the likelihood of choosing each alternative in a given set of options. The findings indicate that overall pseudo R2 value i.e. Nagelkerke 0.768 suggesting the chosen independent variables show the variation probabilities of 76.8%. Thus one unit increase in owned land of farmers increases the probability of the agricultural mechanization ascend towards low to moderate mechanization category by a factor of 2.303 times. However apathy from officials was negatively significant at a 1% level which indicated a unit increase in apathy from officials reduces the probability of agricultural mechanization falling in the moderate category by 10%. The model explains that Wald statistics were significant at 1% level for variables such as Owned land, Apathy, Land fragmentation and Beneficiary (Wald value 7.527 P=0.006, OR= 2.743, 99% CI 1.064 to 7.073) where the probability of farm mechanization ascend from low farm mechanization to moderate mechanization category. The study concludes that farmers who rent their machinery and were direct beneficiaries of Bihar Krishi Roadmap for which Rs. 117074.30 Lakh was under subsidy for agricultural machinery, were having a higher propensity towards mechanization.
Phytochemical screening of Henophytondeserticoss. &Durieu from the El Bayadh region (Algeria).
This study focuses on the valorization of a medicinal plant growing spontaneously in the El Bayadh region. It concerns Henophyton deserti coss & Durieu, known in Arabic as "henatl'ibel," used to treat various conditions such as intestinal disorders, lowering cholesterol levels and blood coagulation, as an antidiabetic, and for skin diseases. Organic extracts were obtained through hydrodistillation (methanolic, ethanolic, aqueous extracts). Phytochemical tests, thin-layer chromatography (TLC), and antioxidant activity of the methanolic extracts were conducted, along with microbiological activity tests for some extracts. Our results indicate that the plant is rich in flavonoids, tannins, phenols, starch, saponins, and sterols, while alkaloids, anthocyanins, and reducing compounds were absent. The DPPH assay showed an IC50 value of 3.69 mg/ml, indicating antioxidant activity. The antimicrobial activity results demonstrated sensitivity of the extracts against the bacterial strains used, including Staphylococcus and Listeria.
STUDY OF THE FORCES ACTING ON NEW CUTTING DRIVING MECHANISM OF RECIPROCATING MOWERS
The solution to the problem of forage procurement largely depends on the availability and technical characteristics of mowers and the perfection of their design. Therefore, it is necessary to modernize existing mowers and create new ones. In this order, first, a crank-and-rocker mechanism used in new cutting drive mechanism of a reciprocating mower is elaborate, and then by using, the vector closed contour method, the mathematical equations describing the main parameters, specially the forces, are defined. Therefore, to validate the obtained equations, the Kazakh Scientific Research Institute of Mechanization and Electrification of Agriculture carried out numerous field experiments. The proposed reciprocating mower with new crank-and-rocker cutting drive mechanism has the ability to work on uneven natural and seeded hayfields, ensuring a reduction in dynamic loads and high-quality execution of the technological process.
