ABSTRACT The irrational consumption of water is one of the greatest problem in the world today. Irrigation of agricultural crops with fish effluent is one way to solve this problem. Rather than disposing of effluents gotten from aquaculture; then providing nutrients from fertilizer and irrigation from another source of water. We could use water containing fish effluent to irrigate agricultural crop. The aim of this study was to determine the effect of irrigating with water from fish ponds on...
ABSTRACT Natural Organic Matter (NOM) fractions in rocks, sediments and soils are known to have good sorptive potentials for frequently occurring Hydrophobic Organic Contaminants (HOCs) such as phenanthrene. Despite widespread occurrence of organic matter-rich rocks, sediments and soils in Nigeria, there is limited information on the sorptive potentials of their NOM fractions for HOCs which may be useful in remediation and clean-up design. This study is aimed at investigating the sorption of...
ABSTRACT Access to market plays a vital role in poverty alleviation among smallholder farmers in Sub-Saharan Africa. Agricultural markets provide income generating opportunities for farmers in rural areas hence improving their livelihoods. Avocado fruit has a high demand in both local and export markets due to its nutritional value and industrial use. However, smallholder avocado farmers have not benefited from this increased demand. The purpose of the study was to assess the effects of trans...

ABSTRACT The quest for the improvement in students' performance based upon their learning efforts in chemistry has continued unabated. This quest has led to the uncovering of new needs which con ameliorate both the teaching and learning transactions. Derived from theoretical and empirical work, the new needs, include the enjoyment of practicals, provision in lecturer-student interaction, and student involvement in decision taking. The present study is aimed at designing, implementing and eval...
ABSTRACT Management is the cornerstone of organizational effectiveness. People‟s efforts are co-ordinated and guided towards achievement of organizational objectives through management processes. People are usually motivated to carry out the management processes in order to satisfy needs either inherent or from the external. Mumias Sugar Company (MSC) is a large-scale organization and hence is controlled by bureaucratic structures. MSC supplies 60% of the sugar consumed in Kenya, but its su...
ABSTRACT This study was conducted to analyze the socio-economic and environmental effects of urban fish farming in Dar es Salaam. Gross Margin was used to determine the profitability of urban fish farming. Results indicate that urban fish farming are operating profitably. The gross margin obtained by tilapia farmers ranges from TZS 658 000/= to 2 515 350/= per pond per production cycle. While gross margin obtained by African catfish farmers ranges from TZS 3 750 000/= to 9 590 000/=. Contrib...
ABSTRACT This study provides empirical evidence on economic impact of contract farming on the income of smallholder farmers of non traditional crops. Specifically it analyses the requirements for farmers’ participation, factors that determine income and effect of paprika contract farming on household income and identifies constraints and prospects of contract farming. A cross section research design was adopted and a purposeful sampling procedure was used to select villages and wards and ...
ABSTRACT The amount of soil organic carbon (SOC) stored in a particular soil is influenced by several factors including climate, vegetation type and age, land management, soil properties and current and past land use. The impacts of land use types on soil organic carbon were assessed. Four land use types were used in the study. Sampled soils were taken at depth of 0-45 cm and at intervals of 15 cm. The soil samples were examined in accordance with the standard methods. The data were analy...
ABSTRACT This research was carried out to determine the effects of three organic fertilizers namely: cattle dung, poultry droppings and pig excreta on the growth of fingerlings of Clarias gariepinus. A total of 120 fingerlings of average length (15.3±2.10)cm and weight (34.2±8.73)g were used for the study. The fingerlings were subjected to three different organic fertilizer treatments. Each treatment was replicated thrice. For proper assessment, a control experiment containing no ...
Abstract: The productivity of shallot is low due to low soil fertility as one of many constraints. Thus this research was conducted to assess the effects of combined application of vermicompost (VC) and inorganic NPS fertilizer on bulb yield, yieldrelated traits, shelf life of shallot, soil physical and chemical properties for sustainable nutrient management without harming the environment. The field experiment consisted of four rates of NPS (0, 50, 100 and 150 kg NPS ha-1) and five VC rates...
ABSTRACT Root-knot nematodes (RKN) (Meloidogyne spp.) cause up to 80 % yield losses in infected vegetables. A study was carried out to; assess the influence of farmers’ knowledge and awareness on RKN damage on African nightshades (AFNS); assess the incidence and severity of RKN on AFNS; characterize the RKN species infecting AFNS; screen the AFNS for response to RKN and determine the efficacy of solarizing soils amended with selected organic materials against RKN. A root-knot nematode surve...
A producer and a buyer enter into a two-party contract when they practice contract farming. A buyer commits to purchasing output from a producer at a predetermined price, quality and timing (Bellemare & Bloem, 2018). In many nations around the globe, contract farming is used to link smallholders’ farmers to profitable markets for higher incomes and better living conditions (Barrett et al., 2012). Early in the nineteenth century, the North American agricultural sector saw the introduction of...
ABSTRACT According to the UN, sea surface temperatures (SST) are increasing at alarming rates and the oceans are increasingly polluted by anthropogenic activities. This thesis sought to determine how two pollutants – cadmium (Cd) and pyrene (PY) interacting with sea surface warming affect copepod egg production (EP), mortality and recycling of ingested food through faecal pellet (FP) production. A field study was conducted on transects established on the Western, Central and Eastern Coast T...
A seminar research was conducted within Sokoto metropolis of Nigeria to identify the physiological and anatomical effects of mistletoe on the tree population, to which the research yield a tremendous result in which the mistletoe affect the tree to a level where the mistletoe brings about the total cell death (apoptosis) of various organs of the organism resulting in the organism total inactivity ie death
