CHAPTER ONE INTRODUCTION 1.1 General Pollution affects more than our water and air; soils also are seriously polluted. It is easy to forget that the soil is more than just a mass of inert matter. In its own way, the soil is a living organism. (I) Soil is a crucial component of the rural and urban environments, and in both cases, land management is the key to soil quality. Pesticides are synthetic organic or inorganic chemicals used to control weeds in fields and lawns, and unwanted or ha...
ABSTRACT Two field experiments were conducted at the Multipurpose Crop Nursery of the University of Education, Winneba, Mampong – Ashanti during the 2015 and 2016 cropping seasons from August to November, 2015 and June to September, 2016 respectively. The objective of the study was to determine the organic and inorganic fertilizer effects on the growth and yield of cabbage (Brassica oleraceae var capitata), and incidence of pest in the forest transition agro – ecological zone of ...
Abstract: Continuous conversion of land for different agricultural production purpose has resulted in degradation of soil resources. The decline of soil fertility and soil organic carbon stock become notable phenomena in the highlands of Ethiopia. The present study was conducted to analyse and quantify the land use/land cover changes over the periods of 28 years and to investigate the influence of A. decurrens tree-based farming system on selected soil properties and soil organic carbon stoc...
ABSTRACT Agriculture remains the mainstay of the African economy as an engine of economic growth and development where 88% of the continent’s populations living in rural areas earn their livelihood from agriculture (Ndambi 2008). Also 80% of Uganda’s cultivated land area falls under subsistence form of agriculture (Kalyebara 2005). It is this phenomenon that prompted a research study whose intention was to investigate the implications of subsistence farming in the natural environment, the...
ABSTRACT Land degradation is a major threat to food security and natural resources management in Rwanda as well as in SSA. The major objective of this study was to evaluate the effects of tillage methods, residue management and fertilizer application on bean and maize yield, soil properties and water productivity in Bugesera District, Rwanda. Experiment was established in Bugesera district located in Eastern province of Rwanda. The experimental design was Split Plot with 4 replications. The m...
ABSTRACT Economic study of the use of organic manure in yellow pepper production in Nsukka Local Government Area of Enugu State was carried out. The study was aimed at; describing the socio economic characteristics of yellow pepper farmers, identifying factors that motivate the use of organic manure by yellow pepper farmers, determining the yellow pepper farmers’ willingness to pay for processed biodegradable waste, determining and comparing the costs and returns from organic manure use onl...
ABSTRACT Sustainable agricultural production in Kenya requires improvement of yields per unit of land while still conserving soil resources. Besides poor soil nutrient status, water is a limiting factor to crop production in the rain-fed farming systems of central highlands of Kenya. Hence, there is need to address soil water scarcity challenges in order to increase crop production. The objective of the study was to determine the effects of tillage and mulching on maize (Zea Mays. L) yield, s...
ABSTRACT Population increase in Matungulu Sub-County in Kenya has led to pressure on arable land where agriculture is the main economic activity. This has caused a gradual shift in land use practices over the years from extensive to intensive agriculture. There has been a decrease in maize yields over the years despite the use of phosphate (P) and nitrogenous (N) fertilizers, which may suggest that the levels of potassium (K) in the soil may be low. Fertilizer application for maize farming ...
ABSTRACT Mozambique lags behind all other Southern and Eastern African countries in maize production leading to maize imports. Soil nutrient depletion, lack of combination of organic resources with mineral resources coupled with high soil acidity has been identified as the main causes of the declining crop yields. Maize yield in smallholder systems in central Mozambique can be increased by optimum utilization of mineral fertilizers combined with cattle manure and other locally available organ...
ABSTRACT Seaweed has many uses which including source of food, in agriculture is used as organic fertilizer and also has been used in medicinal products. However, seaweed farming has side effects on environment and most coastal communities who involved in this farming do not well know. The general objective of this study was to assess environmental impacts of seaweed farming. The specific objectives of the study were including; to identify types of seaweed and activities related to seaweed f...
ABSTRACT Mycotoxins are low-molecular weight secondary metabolites produced by fungi, mostly of the phyla Ascomycota and Basidiomycota. They are noncritical to the instantaneous survival of the organism, and mostly affect its long-term survival. Fungal growth is enhanced by the warm, humid atmosphere and organic substrate-rich soil, such as exists in Nigeria, and they massively infect Nigerian plants and livestock. One consequence is reduced agricultural yield, which leads to food short...
ABSTRACT This study was designed to enhance EPC Mawuko Girls‟ SHS 2 Home Economics students‟ understanding of the classification, naming and writing of the structures of aliphatic organic compounds using molecular models. It was also intended to find out the students‟ views on the use of molecular models in teaching the structural formulae and naming of aliphatic organic compounds. The study was a case study design using the action research approach. The sample for the study was forty-f...
ABSTRACT The study was undertaken to analyze the relationship between mixed farming and soil degradation in Nyarubuye Sub County. The study objectives included; finding out different mixed farming practices in Nyarubuye Sub County, identify impacts of mixed farming on soil degradation in Nyarubuye Sub County and to analyze the solutions of on how to over come soil degradation. Data was collected basing on the above objectives and each objective was handled after the other. Different mixed f...

ABSTRACT Smallholder farming systems in Njoro are characterized by the application of sub- optimal rates or non-utilization of inorganic fertilizers due to their exorbitant prices vis-à-vis low financial returns from crops. Efficient application of natural materials in agro ecosystems, viz. the use of Minjingu phosphate rock (MPR) as a fertilizer is an attractive alternative to inorganic fertilizers, however, releases phosphorous slowly due to its low solubility. The use of the legumes apart...
