Abstract: Efforts to recycle organic waste using black soldier fly (BSF) larvae into high-quality alternative proteiningredients in animal feeds and organic fertilizers have gained momentum worldwide. However, thereis limited information on waste manipulation to increase nutrient retention for enhanced larval perfor-mance and frass fertilizer quality. In the present study, brewer’s spent grain with a carbon to nitrogen (C/N) ratio of 11 (control) was amended with sawdust to obtain substrat...

Deplorable soil fertility characterising resource-poor agrarian communities remain a major constraint for sustainable global food security. Re-mineralisation through appli- cation of rock dust encourages maintainable productivity of degraded soils. This study was planned to appraise the effect of rock dust on root-knot disease of Citrullus lanatus caused by Meloidogyne incognita (Mi). The experiment was laid out in Randomised Complete Block Design with three replications. Soil and root popula...
ABSTRACT This paper presents a review on the literature of tobacco farming on the observed research on the impact of tobacco farming on the livelihoods of smallholder farmers as well its impact on land. In this study I drew on the existing academic structure on tobacco farming in Zimbabwe. An examination of the determinants of farmer partaking in tobacco farming was carried out on 30 smallholder farmers. The case was Mount Bokoto ward24 in Murewa District. This study was therefore initiated ...
ABSTRACT The temporal distribution of four important cocoa mirid species (Distantiella theobroma Dist, Sahlbergella singularis Hagl, Helopeltis bergothii and Bryocoropsis laticollis) was studied in three differently managed cocoa farming systems from May 2013 to April 2014. In addition, the incidence of Bathycoelia thalassina, Characoma stictigrapta, Anomis leona, Earias biplaga, Eulophonotus myrmeleon, Oecophylla longinoda and Crematogaster africana, were recorded. The three systems were: Or...
ABSTRACT Freshly extracted juices obtained from organically and conventionally produced orange and apple fruits were assayed in terms of their nutritional quality. Parameters used in the assessment were total soluble sugars, ascorbic acid content, folic acid concentration, acidity, glucose, fructose, maltose and sucrose contents, as well as the concentrations of sodium, potassium, calcium, iron, zinc and copper. Total and individual sugars were detected using HPLC while brix concentrations we...
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...
The experiment was conducted at the University of Port Harcourt Teaching and Research farm, Port Harcourt, Rivers State, Nigeria from April to August, 2019 on the effects of organic and inorganic fertilizers on the growth and yield of cucumber (Cucumis sativus L). The research was done in a randomized complete block design with four treatments and replicated four times. The treatments include control (no application), NPK 15:15:15, spent mushroom ...
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, ...
