Screen shading can be an effective tool for tea cultivation. However, articles related to this topic are very few, especially the study of winter shading. Therefore, the objectives of this study are to assess the growth impacts of tea plants by deploying different shading screens on the tea canopy. Moreover, another objective is to assess the effects of shading screens on the reduction of freezing injury of tea plants. Black and green color screens, having shading levels of 35%, 55% and 70%, were deployed over tea cultivar: ‘Jin Guanyin’. The unshaded/control (CK) tea plants were also monitored to compare it with the screen shaded tea plants. Index of injury (It) was measured in tea leaves to assess cold/freeze injury. To measure index of injury (It), the tea leaf segments were frozen at –6, –8, and –10 °C for 1 h. Leaf area measurement is one of the essential aspects to observe the growth and development of plants. Therefore, tea leaf area was studied to assess the influence of shading screen on leaf growth uniformity. The results show that: (1) The results of index of injury (It) were found rational from the sampled tea leaves at three different freezing temperatures (e.g., –6 °C, –8 °C and –10 °C). Black-35% treatments showed relatively lower It than other treatments. Hence, the black-35% screens as an effective tool for decreasing freezing damage compared to non-shading treatment (CK). (2) Uniformity of leaf area was analyzed to investigate the effect of shading screens to tea growth. Leaf under black-70% screen showed a good shape. Because plotting the leaf area against leaf length (L), width (W) and (L × W), gave R2 values as 0.9553, 0.8935 and 0.9875 respectively under black-70% screen.
Azadirachtaindica, a genus of family Meliaceae, is generally referred to as Neem and has been documented for its role in curing ailments. All parts of A. indica tree have therapeutic activity and can be used commercially. The plant is kept in use for ages in various medicinal systems such as Ayurveda, Unani, and homoeopathic medicines. It is also regarded as a new medication for cynosis. A. indica is easy to obtain, and its low cost have made it possible for many people to take advantage of this dynamic plant. In the last five decades, significant improvement has made concerning the biological action and therapeutic functions of A. indica and the chemistry of neem compounds. Nowadays, it is regarded asan essential resource of specific biological inventions for developing medicines for different illnesses and industrial products. Utilising traditional medicine and medicinal plants as a regulatory basis for maintaining good health was commonly observed in most developed countries. Over the last century, about 130 pharmaceutical products were discovered by conventional scientists and physicists. This review focuses primarily on the A. indica biological actions, health effects of its ingredients and some of its isolated substances, pharmacological actions, clinical trials, medicinal applications and their safety assessment.
Migraine is a common brain illness with a high rate of impairment caused by a variety of aberrant neural networks interacting at various levels of the central and peripheral nervous systems. Researchers have been able to unravel some neurophysiological pathways and neurotransmitter involvement thanks to a surge in interest in migraine pathophysiology, resulting in the recent development of innovative medicines that could significantly alter the clinical approach to migraine sufferers. The objective of this research is to evaluate the efficacy of Unani coded formulations to allopathic medicine in the treatment of migraines. On an animal model, the toxicity index as well as, safety profile of the test medication were evaluated. A single dosage of 2000 mg/kg was administered to Swiss Albino mice in an acute toxicity investigation; while 3 various dosages were given to Wistar rats in a sub-acute toxicity study. RCTs (Randomized Controlled Clinical Trials) were carried out. In an acute toxicity trial, there was no evidence of morbidity or mortality after a single dosage of 2000 mg/kg/day was given. There were no significant changes in food as well as water consumption, body weight, haematological parameters, renal function parameters, liver function test, or lipid profile in the sub-acute toxicity research. The results of a randomized controlled experiment demonstrated that the effect was essentially identical to that of a placebo in the treatment of migraine.
Hand-made irrigation systems for growing crops is laborious and prone to huge water shortage. Roselle (Hibiscus sabdariffa-linn) is one such crop grown for its high economic and medicinal value which watering is done by hand. It is application includes the production of zobo-a locally produced drink in Nigeria and some West African countries. This work is designed to grow on Roselle crop in the form of an orchard, balcony, gardening, and in offices with watering being automated. A preliminary study of the nature of the soil in the biological garden of the University of Lagos was carried out in 2020. Roselle seeds were purchased locally and they were planted according to standard practice with the seed germinated within 1 - 2 weeks. 6-Soil bags filled with the sampled soil were used for the planting of Roselle which was planted in three rows by two columns in a nursery. The threshold level to irrigate Roselle crops, reference evapotranspiration, Kc were determined from weather data using the Blaney-Criddle method. The Rainfalls and temperatures data in Lagos State, Nigeria, were gathered for one year covering May 2019 to February 2020. The daily water requirement of the Hibiscus sabdariffa for this area was calculated and set as a threshold. There was a link between the Roselle plant through several computer programs and sets of artificially intelligent devices, sensors, pumps that control the water application process. For instance, below the input threshold value, the pump is thus activated through the sensors for irrigation. The Roselle water irrigation systems were developed locally at the Department of Systems Engineering, the University of Lagos as materials for construction sourced locally. They include the Arduino control system, breadboard, power bank, Raspberry Pi, the breadboard, soil moisture meter, Homasy 80 Submersible Water Pump, a USB cord, and a casing were purchased locally at hub360 Arena Oshodi Lagos and the fabrication, coupling, and testing were carried out. The control unit of the irrigation systems sensed the moisture level of the soil under the Roselle plant and were transmitted to the control unit which in turn compared with the predetermined threshold level. The Roselle drip irrigation systems worked perfectly with the set conditions. The soil moisture was measured with a moisture meter in percentage mapped into 0-100 range. Once the moisture value of the soil beneath the Roselle was lower than the calculated threshold value of 3.9 mm/day (39%), the relay will turn ON and the valve automatically opens in readiness to apply the required amount of water(mm). Whenever the moisture value was higher than this threshold value, the relay then tripped off and the pump valve was closed. This system can irrigate about 10m by 10m farm planted with Roselle. All these are displayed for reading on the Nokia LCD 5110 connected to the Arduino board system. To reduce human intervention in monitoring the growth of Roselle (Hibiscus sabdariffa). The automated systems have about 60-70% water management, reduce loss of water and minimize human-labored to the barest minimum.
The working efficiency of disc coulters used for conservation tillage in intensive rice-based farming systems is inhibited by the degraded paddy soils and excessive crop residue conditions. Conventional coulters often experience high working resistance and low straw-cutting efficiency. By embracing bionic designs, the efficacy of coulters can be improved. This study was designed to investigate the working performance of a bionic disc coulter developed by modifying a conventional disc to simulate the arc-shaped profile of the mole rat’s (Scaptochirus moschatus) claw. Field experiments were conducted to evaluate the bionic disc’s tillage resistance forces, straw cutting efficiency, and soil disturbance effects; in comparison to a conventional notched coulter at three tillage depths (i.e., 40, 70, and 100 mm). The study revealed that the bionic disc minimized draft forces by up to 45.24% and vertical resistance forces by up to 23.57%. Meanwhile, the furrow-width disturbances were minimized by up to 31.98% and straw cutting efficiency improved by up to 12.08%. These outcomes demonstrated that the bionic coulter is energy-efficient and well-suited to rehabilitate degraded soils with minimal disturbance, besides managing the excessive crop residues in intensive rice-based farming systems. These advantages would help improve seeding performance in the presence of crop residue cover, create favorable plant growth conditions, and facilitate the smooth flow of field operations. Bionic design of soil-engaging tools therefore improves the working performance of coulters and advances the implementation of conservation farming in intensive farming systems.
