INTRODUCTION Wood-cement bonded particleboard, was originally invented in Germany about eight decades ago. Since then it has been gaining acceptance in many parts of the world as a sheet element or the building construction-industry. The" interest in the board can be associated with a number of factors. It is highly resistant to flre, insect aud fungal attack and has excellent weather ability and good accoustic insulation properties (Deppe,1974; Dinwoodie, 1978;1981). With respect to the afor...
A deterministic bio-economic model that incorporates risk for pasture-based dairy cattle production in the tropics was developed. Two production circumstances were considered: fixed pasture (FP) and fixed herd size (FH). In each circumstance, efficiencies (both economic and biological) and profit were calculated based on milk marketing on volume, and on volume and butter fat content. Additionally, a profit function was used to estimate risk-rated profit(s) where the intensity of the farm...
Developing countries, Kenya included are mostly affected by food problems and poverty as a result of high dependence on agriculture. Agriculture in Kenya is dominated by smallholder farmers, whose production is hampered by climate variability, declining land sizes and low agricultural technologies. Agricultural intensification is aimed at solving the problem of low agricultural productivity and poverty through increasing farm output per unit land area. However it is still not clear the e...
ABSTRACT Nutrition influences postpartum ovarian activity but the effects of pre and postpartum feeding on metabolte and hormonal changes and their subsequent influence on reproductive performance remains unclear. This study attempted to explain effects of nutrition on these changes and their ultimate impact on reproductive performance of lactating cows. Forty in-calf cows comprising 20 Friesians and 20 Sahiwals were randomly assigned to 5 dietary groups of 4 cows per breed. Upon calving, cow...
Soybean [Glycine max (L) Merrill] yields in Kenya range from 445-1200 kg ha -1 against potential yields of 3500 kg ha -1 . The low yields are attributed to soil moisture stress and use of poor agronomic practices. The objectives of the study were to determine effect of soil moisture regimes on CO2 assimilation, growth and yield of selected soybean cultivars; to determine effect of planting density on yield and yield components of soybean and to determine effect of soybean and maize i...
Cereal banks in Kenya were started by Government, non-governmental organizations (NGOs) and other civil society with the aim of enhancing local food security, improving incomes and livelihoods for maize farmers through collective marketing. Despite efforts of establishing them, majority have collapsed once outside support is withdrawn. Generally it is known that farmer organizations including cereal banks tend to collapse if there is no participation in group activities, poor group manag...
Small import-dependent countries in the world, especially in Africa, are deeply affected by the food insecurity and economic crises. To solve this problem, the Government of Ethiopia has adopted a different strategy in agricultural sector by focusing on how to increase the volume of production. However, marketing aspect has been given less attention. In order to improve the market efficiency, significant numbers of empirical studies have been conducted on market integration but they focus...
ABSTRACT The Sahiwal population in Kenya, which is bred under a closed nucleus, is faced with declining effective population size over the years and rate of inbreeding per generation >1% beyond which it should not exceed for a population to maintain its long-term fitness and viability. This study estimated gene origin statistics, Wright’s F-statistics, current and future rates of inbreeding, coancestry and effective population size and genetic gain in lactation milk yield at predetermined r...
Agricultural extension services play an important role in boosting agricultural productivity worldwide. Despite concerted efforts by pastoralists in Wajir County to access agriculturalextension services delivered by agricultural public service providers, Non-Governmental Organizations (NGOs) and private extension agents, the access to these services is inadequate. This has led to low levels of agricultural productivity, ultimately leading to high levels of poverty and food insecurity in...
Genetic and phenotypic parameters for longevity, genetic relationship between longevity and growth, milk yield and fertility traits and rate of inbreeding were estimated for Sahiwal cattle in Kenya. The aim was to assess the genetic diversity and inbreeding depression for performance traits. Data utilized were for cows born between 1972 and 2004 and with milk production records between 1976 and 2008. Measures of longevity related to productive life were: time between birth (Long_1) or fi...
ABSTRACT Food security is a major concern of the world, especially among the poor in developing countries. Pulses, including dry beans, play a crucial role in ensuring food security, particularly in Sub-Saharan Africa where over 200 million people depend on beans as part of their main diet. In Rwanda, dry beans are an important staple food and constitute the primary source of protein for about 90% of Rwandan households. Unfortunately, dry beans are a slow-cooking food, requiring a lot of time...
The potential of sorghum to meet food, feed and farm income needs of smallholder farmers in arid areas of Kenya relies on the identification and cultivation of appropriate varieties. Sorghum cultivation for food grain and quality fodder from the same crop is not well established among varieties in Kenya. The fodder– cum–grain yield potential of important varieties required to be identified to enable farmers in semi-arid areas to select appropriate varieties and crop management progra...
ABSTRACT Botswana is classified as an upper middle income country and despite having attained such economic growth, the country still faces socio-economic challenges such as poverty. The current poverty rate is 20.7% while rural poverty is 24.7% which is relatively higher for an upper middle income country. In order to address this problem, the government introduced the Poverty Eradication Programme. This study therefore, sought to assess the income, expenditure and consumption dimensions of ...
Farm diversification is considered an optimal farm plan decision for mitigatingvarying degrees of risks and uncertainties which surround agricultural production, and also has a benefit of stabilizing or increasing income. Diversified agriculture is widely practicedin Konoin district but smallholder farmers earn low incomes asevidenced by poor living standards amongst the smallholders. The purpose of the study was to evaluate the role of on-farm diversification in poverty alleviation amon...
ABSTRACT The agriculture sector supports the livelihoods of the majority of the population in Rwanda. Currently, the sector is dominated by smallholder farmers most of whom are women. In order to modernize and transform agriculture to market orientation, the government has put in place agriculture sector development programs for instance the Crop Intensification Program. One of the targeted crops in the program is the common bean. Nearly all households in Rwanda produce the common bean. Thoug...
