This study aimed to evaluate the influence of organomineral fertilizer on the growth and mineral composition of Moringa oleifera organs. The experiment included three doses of cow dung, three doses of mineral fertilizers and two doses combining mineral fertilizers and cow dung. Soil samples and samples of M. oleifera organs were analyzed. Results revealed the contribution of fertilizer to improve soil chemical properties, except pH. The best vegetative development was obtained with the d...
ABSTRACT In Nigeria, use of urine for fertigation has been limited because of its liquid form, odour and the unsanitary disposal methods. This poses great hazard to man and the environment. Converting urine into dry fertilizer product (struvite) helps extract nutrients contained in urine and also eliminates handling problems. The study was aimed at converting urine to struvite and comparing its effectiveness on plant growth with inorganic fertilizer (NPK). The study involved the extraction ...
ABSTRACT This research was primarily designed to help improve students’ academic performance in naming organic compounds using molecular model set in Effiduase Senior High School in the Sekyere East district of the Ashanti Region. Experimental design was used for this study where the form three science classes were put into two groups. Science one students formed the control group and were taught using traditional approach while the science two students comprised the experimental group a...

ABSTRACT Organic-inorganic hybrid perovskite solar cells have attracted great attention in the photovoltaic research community in recent years due to its ease of processing, low cost of production, superb light-harvesting characteristics, and relatively high efficiency which make it more preferable over other existing solar cell materials. Lead-based perovskites (CH3NH3PbX3, X= Cl, I, Br) solar cells have recently attained a high efficiency of ~19.3% which far surpasses the efficiencies of m...
ABSTRACT Ethiopia’s agricultural sector accounts to 40 percent of national Gross Domestic Product. This shows that the sector is important in improving the livelihoods of the bulk of the population. Despite its importance, the agricultural sector in Ethiopia is characterized by low productivity. To improve this and overall economic growth, the Ethiopian government has focused on promotion of organic fertilizer use. However, adoption of organic fertilizer remains low in most parts of Ethiopi...
Abstract: Knowledge of quantity and composition of urban solid waste is required and considered as a basis for designing and operating appropriate solid waste management systems. Cognizant of this, a study was initiated to characterize the household solid waste generation rate and its physico-chemical composition based on a field survey and waste measurement in Haramaya town, Eastern Hararghe Zone, Ethiopia. For this study households were stratified into three groups based on level of their ...
ABSTRACT Taking into account the danger in the continual use of synthetic chemicals in the production of vegetables and the increase in demand for organic products, this research set out to ascertain the perception of consumers on organic products, and estimate consumer willingness to pay for organic cabbage in the Accra metropolitan area of Ghana. Furthermore, the study identifies the factors that influence the consumers‟ willingness to pay premium for organic cabbage. A face-toface ...
Abstract Agricultural mechanization embraces the use of tools, implements, and machines for a wide range of farm operations from land preparation to planting, harvesting, omfarm processing, storage, and marketing of products while soil degradation is defined as the process which lowersthe current and/or the potential capability of soil. This study was therefore to assess the degree of mechanized agriculture and its role in soil degradation in Moiben division in Uasin Gishu district, Rift Va...
Abstract Natural organic matter (NOM) is a generic term for a mixture of organic, slightly watersoluble components found in soil, sediment and natural waters, which represents severe challenges for the process control in water treatment plants as well as water distribution systems. The effective removal of NOM during drinking water treatment requires a good understanding of its character. The current study aimed to identify and quantify NOM present in the Windhoek Goreangab Operating Company...
ABSTRACT Secondary school agriculture curriculum was introduced in Kenya to equip learners with knowledge on the basic principles of farming. The intention was to bring out school graduates who would embrace self-employment and even create employment for others in their farms. Agriculture sector contributes significantly to economic development of this country through; provision of food, employment, market for industrial goods, raw materials for industries and foreign exchange. To realize the...
Abstract: Building climate-resilient farming systems is important to promote the sustainability of agriculture at the global level. Scaling-up agroecological approaches in main staple crops, such as maize, is particularly important in enhancing the climate resilience of millions of smallholder farmers in developing countries. In this regard, push–pull technology (PPT) is an ecological approach to a farming system that aims to improve the climate resilience of maize producers in a smallhold...
ABSTRACT The WAEC Chief Examiners’ Reports in Ghana have repeatedly lamented the weakness exhibited by most Chemistry students in IUPAC nomenclature of organic compounds in the West Africa Senior Secondary Certificate Examination. This study was a step to determine the knowledge level of some Chemistry students in IUPAC nomenclature of organic compounds. A cross-sectional survey was adopted to collect both quantitative and qualitative data. In all, 245 SHS4 Chemistry students selected from ...
ABSTRACTThe isolation, identification and characterization of bacteria from organic waste were carried out. Sawdust waste (plant organic waste source) and abattoir waste water (animal organic waste source) samples were collected. The media used were nutrient agar for total aerobic plate count, McConkey agar for coliform count and cellulolytic media for cellulolytic count. The pour plate method was employed. Colonial morphology, gram staining and biochemical tests were used for the identificat...
Abstract: Tin (Sn) is a promising substitute for lead (Pb) in organic–inorganic hybrid halide perovskite-photovoltaic devices, but it is prone to delivering low power conversion efficiencies (PCEs) due to the poor quality of Sn-perovskite films. In this work, anilinium hypophosphite (AHP) co-additive is used to fabricate high-quality FASnI3 (FA+: formamidinium) perovskite films with suppressed phase-segregation and prolonged charge carrier lifetime. Perovskite films containing 0.05 M AHP a...
