Abstract: Garlic (Alium sativum L) is an important vegetable crop in Ethiopia. However, the yield of the crop is often constrained by low and imbalance nutrient supply in the soil. Therefore a field experiment was conducted at Ambo University, Gudar campus experimental site to study the effect of inorganic NPS fertilizer and organic cattle manure on growth, yield and yield components of garlic (Alium sativum L) during 2019/2020 main cropping season. A Tsadey variety was used for the study. The treatment consisted of four levels of NPS (0, 50, 100 and 150kg ha-1), and four levels of cattle manure (0, 5, 10 and 15 t ha-1). The experiment was laid out as randomized complete block design (RCBD) in factorial arrangement, and replicated three times. The phonological data, such as plant growth, bulb yield and yield components of the crop was collected. The result revealed that the main effects of NPS fertilizer and cattle manure was significantly (p<0.01) affected growth, yield and yield components of garlic such as plant height, days to maturity, leaf length and leaf number per plant and the like. In addition the interaction effects of NPS and CM also significantly (p<0.01) influenced, fresh biomass yield, bulb diameter, total bulb yield and harvest index. The highest total bulb yield 8.62 t ha-1 was recorded from the combination of 150 kg NPS ha-1 and 10 t ha-1 of CM. Marketable yield and mean clove number was significantly influenced by the interaction effect of NPS and CM application, whereas unmarketable bulb yield does not significantly influenced by the interaction of NPS and CM. The highest 8.25 t ha-1 marketable yield was recorded from combined application of 150 kg NPS ha-1 with 10 t ha-1 of CM, while the lowest marketable yield was recorded from the control treatments. Maximum 75.4% harvest index was also recorded from the combined application of 150 NPS kg ha-1 and 10 t ha-1, and the highest benefit (616890 ETB ha-1) was recorded at combined application of 150 kg NPS ha-1 and 10 CM. it can, be concluded that, combined application of 150 kg NPS ha-1 and 10 t CM. led to the maximum growth, yield and yield component of the garlic crop and it is recommended at the study area.

Abstract: Nowadays, the utilization of synthetic fertilizer has significant adverse effects on the soil, ecosystem, and human health. To evade the use of synthetic fertilizers, the production of organic fertilizer from organic matter particularly from keratin-based materials, has become more popular as a way to solve the problems related to soil conditioning and human health. In addition, the impact of different methods on the extraction of organic fertilizer from keratin-based materials is discussed. Hence, the review was conducted to assess the effect of different methods like acid hydrolysis, base hydrolysis, and hydrothermal treatment on organic fertilizer extraction from keratin materials. Therefore, this revised seminar currently, as it deters the environmental pollution caused by chemical hydrolysis and hydrothermal treatment, the microbial fermentation by immobilized cell for organic fertilizer production is essential to enhancing a green environment and avoiding the risks related to human health.

Abstract: The environment serves as a critical lifeline for both humanity and diverse biotic organisms, necessitating the imperative of Environmental conservation to safeguard the natural world from the deleterious impacts of human activities. This paper explores the intersection of environmental sustainability and biotechnological advancements in East Africa. In the face of global environmental challenges, the study accentuates the importance of transitioning to eco-friendly industrial processes, with biotechnological tools emerging as sustainable alternatives to traditional methods. The research delves into the multifaceted applications of biotechnology, showcasing its potential to revolutionize the preservation and rehabilitation of contaminated environments, particularly in soil and water. Groundbreaking techniques such as in vitro culture and cryopreservation are highlighted for their efficacy in collecting and conserving genetic resources, particularly for species that pose challenges when conserved as seeds. Plant biotechnology emerges as a singular solution capable of addressing agricultural and food security concerns while simultaneously mitigating environmental issues in East Africa. A pivotal aspect of the examination is the emphasis on multidisciplinary infrastructure, recognizing the need for collaborative efforts to maximize the impact of biotechnological interventions. The paper explores diverse applications, including the role of plant biotechnology in enhancing agriculture, the contributions of bioremediation in ecosystem restoration, the transformative impact of genetic engineering on agriculture, and the potential of synthetic biology in providing renewable energy solutions. The results underscore the critical role played by biotechnology in promoting environmental conservation, fostering sustainable development, and addressing the unique challenges faced by East Africa. The findings contribute to the growing body of knowledge on the nexus between biotechnological innovations and environmental sustainability, providing insights that can inform policies, strategies, and collaborative initiatives aimed at achieving a harmonious balance between human activities and the natural world in the East African context.

Abstract: The Yato physicochemical water purification station is located in the commune of Dibombari in the Littoral-Cameroon region. It is one of the largest drinking water production stations in the Central African sub-region. This work aims to evaluate the agronomic power of the sludge from this drinking water production station. To achieve this objective, mixed samples of sludge from sludge treatment basins (taken according to the technique described in GIDS-A003 point 6 as explained in the Solid and pasty waste sampling strategy of the Code of Good Practice No. 2). and primary settling basins (collected in transparent 1.5L polyethylene terephthalate bottles) were analyzed. Likewise, three soil samples (marsh, Point 1 and Point 2) were taken and then sent to the laboratory where physicochemical analyzes were carried out. The characteristics of the samples that were analyzed are: particle size, texture (sand, silt, clay) and physicochemistry (organic matter, CEC, sum of exchangeable bases, calcium, nitrogen, potassium and magnesium). The results obtained show that the soils exposed to contamination from the sludge of the station have better agronomic properties both on a physical level with a stable structure favorable to plant growth and good aeration unlike the soils far from the station which presented a high risk. degradation; that on the chemical level with an optimal cationic balance, a high reserve of exchangeable bases, a strong CEC but average limitations in assimilable phosphorus and pH unlike the soil far from the station which presented an insufficiency of potassium which did not facilitate a balance cationic, a low CEC but a pH above 5.5 which is the value recommended in agronomy. Biochemically, organic matter is above 2% in all soils, a mineralization rate less than 20 favoring the rapid mineralization of carbon and a release of nitrogen available to the plant. These results obtained allow us to conclude that the sludge from the Yato station can be used in agronomy as an organic fertilizer in order to correct the soil structure, the CEC, the cationic balances and also provide the soil with a good base reserve. However, treating this sludge with lime could regulate the pH of the soil and reduce the mobility of heavy metals in the soil.
