Opportunities for Quality Seed Production and Diffusion through Integration of the Informal Systems in Sub-Saharan Africa
(videleaf, 2020)In perpetuating the preferred crop species, seed is exchanged among family members, neighboring communities or between tribes and regions according to customs and practices in many African traditions. Overtime, this ... -
Mechanisms and Sources of Resistance in Tropical Maize Inbred Lines to Chilopartellus Stem Borers
(Journal of Agricultural Science, 2020)Developing maize with durable resistance to maize stem borers could be enhanced by identifying genotypes with different mechanisms of resistance and pyramiding the resistances into high yielding genotypes. This study was ... -
The analogy of simple and inter simple sequence repeat markers in the assessment of genetic diversity of pumpkin accessions in Kenya
(Innspub, 2020-09)Pumpkin is found growing in many parts of Kenya although its genetic variation has not been determined using available molecular markers. This study compared SSR and ISSR efficacy in assessing diversity of 139 pumpkin accessions ... -
Effects of Earthing up and Pruning Systems on Growth and Yield of Tomato (Solanum lycopersicon.)
(Research gate, 2020)Tomato (Solanum lycopersicon) is an important crop cultivated and consumed worldwide. It provides wide variety of nutrients with many health-related benefits like, protection against cancer, maintains blood pressure and ... -
Multinomial Logistic Regression Analysis of Factors Influencing Food Safety, Hygiene Awareness and Practices Among Street Food Vendors In Kiambu County, Kenya.
(Enviro Research Publishers., 2020)Street food vending is a very popular and unique part of the informal sector, particularly in developing countries. However, the safety of street vended foods is a major public health concern since poor food safety and ... -
Effect of Institutional and Farmer Based Climate Change Adaptation Measures on Crop Production in Mavuria Ward, Mbeere South Sub-county, Embu County, Kenya
(Research gate, 2020)Africa is under pressure from climate stresses and is highly vulnerable to the impacts of climate change. In Kenya, agriculture is the backbone of the economy making it an important contributor to food security of rural ... -
Analysis of Institutional Factors Affecting Optimization of Coffee Yields in Chuka Sub-County, Tharaka-Nithi County, Kenya
(Research gate, 2020)The importance of coffee production in the world economy cannot be ruled out due to its contribution in the developing countries in areas such as creation of employment and rise in foreign exchange. Most of the coffee ... -
Synergistic Evaluation of Selected Plant Extracts on Potency of Pyrethrins against the Maize Weevil, Sitophilus zea-mais (MOTSCH.)
(Merit Res. J. Agric. Sci. Soil Sci., 2020)The interest in utilization of botanical insecticides, particularly essential oils have become increasingly relevant in the control of insect pests. Many plant products and their bioactive compounds with repellent, antifeeding ... -
Screening of Plant Extracts Possessing Methylenedioxyphenyl (MDP) Group as Potential Synergists in Insecticide Formulations using the Maize Weevil, Sitophilus Zea-mais (Motsch.)
(Merit Research Journals, 2020)Synergists are compounds that are either negligibly toxic or non-toxic to insects when applied on their own, but enhance the efficacy of an insecticide. Many insects are able to detoxify insecticide molecules and survive ... -
Variation in Seagrass Carbon Stocks Between Tropical Estuarine and Marine Mangrove-Fringed Creeks
(Frontiers in Marine Science, 2020)Seagrass and associated blue carbon ecosystems are important carbon sinks, and hence understanding their spatial and temporal variability is vital in appreciating their potential roles in climate change mitigation and ... -
Nutrient management options for enhancing productivity and profitability of conservation agriculture under on-farm conditions in central highlands of Kenya
(AIMS Agriculture and Food, 2020)Decline in soil fertility is one of the major constraints to sustainable crop production and profitability. To meet the increasing demand for the growing population the issue of low soil fertility needs to be addressed. ... -
