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.
Development of Profitability-Based Ranking of Important Cereal Crops in Different States of India and its Implications
In Agriculture, the decision making by farmers depends on number of factors starting from climate, knowledge, economic cost and benefits, markets etc. Among them the profit from the crop is also one of the major factors. The increase or decrease in area under the crop by farmers mostly depends on profits from the crop. This profit from the crop is regularly changing. In important cereal crops, the profitability-based ranking is developed for important cereal crops in different states of India. In case of paddy, it is found that Punjab, MP, Haryana etc. are leaders in reaping benefits while other states as West Bengal, UP, Jharkhand etc. are getting lesser benefits from the crops. In case of Wheat, MP, Gujarat, Haryana, Punjab etc. are leading states in profitability, while Maharashtra, Karnataka, West Bengal are earning lesser profits. In maize, it is found that Maharashtra, Bihar, Andhra Pradesh etc. are leading states in profitability while Gujarat, Rajasthan, HP etc. are earning lesser profits. In Jowar, Andhra Pradesh and MP are leading states in profitability while Tamil Nadu, Maharashtra etc. are earning lesser profits. In case of Bajra, it is found that Gujarat has higher profitability while UP, Haryana, Maharashtra etc. are earning lesser profits. In case of Ragi, Karnataka and Odisha are leading states, but the profitability is very low. The higher profits in crops in region will lead to higher area of the crop over the period, so as an indicator, the efforts should be made to regulate the profits from all crops to maintain the diversity in area and trade between the regions. The number of factors are associated with higher and lesser profits in cereal crops as availability of suitable climate, inputs, irrigation facility, high yielding seed, consumption pattern, market support at higher price. By providing some of these facilities, the diversity can be created in cereals crops in the region. Higher the concentration of few crops in the region, will lead to imbalance of resources, pest and diseases and inequality.
CORRELATION BETWEEN POPULATION OF MAJOR INSECT PESTS AND WEATHER PARAMETERS IN CHILLI (CAPSICUM ANNUUM L.)
The present investigations were carried out at farmers’ fields, Jabalpur, Madhya Pradesh (Central India) during Rabi 2017-18 and 2018-19 growing seasons. Regular weekly observations were recorded in chilli crop on farmers' fields, at four locations, during both the years. Studies on the correlation of insect pests and natural enemies in chilli crop revealed that five species of insects i.e. whiteflies, Bemisia tabaci (Gennadius), thrips, Scirtothrips dorsalis Hood, jassids, Amrasca biguttula biguttula (Ishida), Mites, Polyphagotarsonemus latus (Banks), and fruit-borers, Helicoverpa armigera Hubner, one species of predator Coccinella transversalis Fabricius and also leaf curl incidence correlation with whiteflies to be a workout. During 2017-18 the correlation studies revealed that the minimum temperature, morning vapor pressure, and evaporation had a significant negative correlation (r= -0.471, -0.498, and -0.458 respectively) with the whiteflies population, whereas, none of the weather parameters showed a significant impact on thrips and fruit borer population. Rainfall had a significant positive correlation (r= 0.476 and 0.478) with jassids & mites. During 2018-19 the correlation studies revealed that maximum temperature, minimum temperature, morning vapor pressure, evening vapor pressure, and evaporation had a significant negative correlation (r= -0.476, -0.547, -0.572, -0.431, and -0.464, respectively) with whiteflies population. Morning relative humidity had a significant negative correlation (r= -0.554) with the thrips population. Wind velocity had a significant positive correlation (r= 0.458) with the jassids population. Morning relative humidity and evening relative humidity had a significant positive correlation (r= 0.452 and 0.472 respectively) with the mite population, while evaporation had a significant negative correlation (r= -0.458) with it. Fruit borer did not show correlation with any weather factor. In the year 2017-18, the correlation studies revealed that rainfall had a significant positive correlation (r= 0.499) with the ladybird beetles population while during 2018-19 it was non-significant. During both the years, 2017-18 and 2018-19 Rabi season the leaf curl incidence did not show a significant correlation with the mean populations of B. tabaci during different meteorological standard weeks.
Prevalence and Pathology of Foot and Mouth disease in swine of Western Uttar Pradesh
Foot and mouth disease is highly contagious viral disease of swine caused by aphtho virus of family picornaviridae characterised by fever and formation of vesicles on the buccal mucosa, feet and teat. This disease is rarely fatal and have very high morbidity and low mortality. It causes sudden death in young piglets. A study was undertaken regarding the sero-prevalence, hemato-biochemical, clinical signs and histopathological study of FMD in pigs in Western Uttar Pradesh. The present study was undertaken in various places of western Uttar Pradesh for the period of twelve months i.e., from May 2020 to April 2021. A total of 2640 animals from different farms in various places of western UP were selected for the study. The seroprevalence of FMD by enzyme-linked immunosorbent assay (ELISA) was observed as 26.51%. Haematology revealed a decrease in total erythrocyte count (TEC), total leukocyte count (TLC), packed cell volume (PCV) and hemoglobin (Hb) value in the animals found seropositive for FMD in comparison to the seronegative animals. Serum biochemical test results showed an increase in ALT, AST values as well as serum creatinine and BUN values in the animals found seropositive for FMD. Clinical signs includes fever, lameness, blisters and ulcers were seen on the oral mucosa, feet and teats. Gross observation revealed vesicular lesions and ulcerations of the dorsal surface of tongue, snout and foot region, myocarditis and petechial haemorrhage in heart. Microscopically intercellular oedema in the stratum spinosum, micro vesicle formations in skin, inter-alveolar septal thickening due to mononuclear cells infiltration and emphysema in lungs were observed indicating the secondary bacterial infection.
