ABSTRACT The aim of this study was to investigate the effects of land degradation on agricultural land use, planning and management in Kalama Division, Machakos County; and specifically determined farmers’ considerations of land suitability for selected types of agricultural land uses in varying cropping zones, investigated farmers’ local environmental knowledge of land degradation indicators and finally documented farmers’ land management strategies and practices for soil and water con...
Abstract: The aim of this study was to investigate the effects of land degradation on agricultural land use, planning and management in Kalama Division, Machakos County; and specifically determined farmers’ considerations of land suitability for selected types of agricultural land uses in varying cropping zones, investigated farmers’ local environmental knowledge of land degradation indicators and finally documented farmers’ land management strategies and practices for soil and water c...
ABSTRACT Empirical studies across many developing countries document that improving crop farming is the main pathway out of poverty .It’s for this reason that the main Objectives of the study was to find out the contribution of crop farming on economic welfare and other objectives were to identify major factors that affect crop farming and to establish the relationship between crop farming and economic welfare. This study considered crop farming as the independent variable and economic welf...
ABSTRACT Deficits in soil moisture and low soil fertility are major constraints to smallholder farming systems in Sub-Saharan Africa. Farmers in Tharaka-Nithi County, Kenya, have over the decades suffered huge declines in crop yields as a result of continuous cultivation with inadequate replenishments of the lost soil nutrients and lack of appropriate soil water conservation technologies. Experiments were set up at Kigogo primary school, Mukuuni location in Tharaka-Nithi County to determine ...
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 poverty alleviation. In this study I drew on the existing academic structure on tobacco farming in Zimbabwe. An examination of the factors that led farmers in partaking tobacco farming was carried out on 86smallholder farmers. The case was in Centenary District. This study was therefore initiated wi...
ABSTRACT The rise of contract farming and vertically integrated firms of production and marketing is undoubtly one of the most important changes in Tanzania economy. The study examined new role of contract farming (CF) in Tanzania towards designing partnership model in the light of transformation and industrialization of agriculture. The specific objectives were (i) To describe contractual arrangement found in the study area (ii) To examine the role of contractual arrangement in reducing tra...
ABSTRACT The main objective of this study is to determine the effects of the pelleted and unpelleted composted organic materials on the growth and yield of three varieties of cucumber (Cucumis sativus L.). The specific objectives were to: determine the physical and chemical properties of pelleted and unpelleted composted organic materials, determine the effects of pelleted and unpelleted composted organic materials on the growth and yield of three varieties of cucumber (Cucumis sativus L.) an...
ABSTRACT This work presents the responses of optical properties and mechanical failure of layers of stretchable organic electronic structures under tension using analytical, simulations, and experimental techniques. The interfacial contact around dust particles was modelled. The deformation induced during stretching was also modelled before simulating the stress distributions and calculating the crack driving forces of the layers using finite element analysis. The finite element simulation o...
ABSTRACT The present study was carried out in 2014 in Rombo District, Kilimanjaro, Tanzania, in order to classify Chagga agroforestry home gardens and establish their relative contributions to food, income and wood energy to the local communities. The study methodology included random selection of four divisions, one ward from each division, one village from each ward and 30 households per village forming a total sample of 120 households. A social survey was subsequently carried out using q...
ABSTRACT In South Kivu Eastern of DR.Congo, most soils are highly weathered, leached and have low nutrients content resulting to low agricultural productivity. The objectives of the study was (i)to evaluate the effect of combining rhizobia inoculation and different fertilizer amendment on biomass and grain yields,(ii) to assess the nitrogen fixation efficacy of commercial rhizobia strains and (iii) to assess the effect of combining rhizobia inoculation and different fertilizer amendments on s...
WHAT IS POLLUTION Pollution is the contamination of harmful substance to the environment. It is the introduction of contaminant into the natural environment that causes adverse change. Pollution can take a form of chemical substances or energy, such as noise, heat or light. The components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or non point source pollution. FORMS OF POLLUTIONS Air pollution:-...
Abstract. A brief review of the literature on the effects of nitrate and ammonium nitrogen sources on plant growth, and the assimilation of those nitrogen sources, has been presented. A water culture technique for the growth of maize was developed. The use of a gravel rooting medium with nutrients recycling through the rooting medium, and an iron supplement in the form of ferric citrate, resulted in superior growth of nitrate-fed plants in comparison to that observed with a hydroponic growth...
ABSTRACT Agriculture contributes the highest in the country’s economy. Despite agriculture being taught in secondary schools, many secondary school graduates seem not to participate in farming activities in Nyandarua West Sub-County. Although it is not clear whether farmers who have studied agriculture in secondary school are making use of the knowledge gained and whether they find it helpful in their careers, there has never been any comprehensive study to investigate the relationship betw...
Abstract: Declining soil fertility is one of the major problems causing yield reduction in Ethiopia. Farmers at Areka apply both organic and inorganic fertilizers to overcome the problem and increase yield of potato. However, information on the application of farmyard manure and chemical fertilizer is inadequate to the area to increase the yield of potato crop. Therefore, an experiment was conducted at Areka, Southern Ethiopia during the 2016 cropping season with the objective of assessing t...
Abstract The rise in antibiotic resistance has resulted in decreasing numbers of effective antimicrobial agents available to treat infections caused by multi‐drug resistant (MDR) bacteria. This has necessitated a search for new antimicrobial agents. Herbal remedies may offer alternative treatment options especially because they elicit little or no transferable resistance if used in optimal concentrations. This study evaluated the antimicrobial properties of W. ugandensis against eight mult...
