These two causes are the main challenges facing small-scale farmers in food production especially in semi-arid areas of the country. To overcome these challenges, soil and water management technologies especially those in soil and water conservation need to be embraced. The aim of the study was to determine the effect of tied ridges, fertilizers and cropping systems on ...

Determination Of Levels Of Some Vitamins In Amaranthus Hypochondriacus And Amaranthus Cruenthus Leaves And Grains From Selected Areas Of Kenya

Vitamin deficiencies are health hazards in some parts of Kenya. These are attributed to inadequate access to vitamin-rich foods occasioned by decline in agricultural production due to unfavourable climatic conditions, low purchasing power due to poverty, over reliance on staple foods and dependence on highly refined foods, which are poor in vitamins. Higher intake of vitamin-rich vegetables and grains can alleviate this problem. Grain amaranth (GA), which is relatively a new crop in Ken...

Evaluation Of Root- Knot Nematode Management Strategies Based On Nematode Distribution In Tomato (Solanum Lycopersicum) Fields In Mwea, Kirinyaga County, Kenya

Plant parasitic nematodes (PPN), particularly root-knot nematodes (RKN) are a serious pest problem in smallholder tomato farms in Kenya. For sustainable food production, effective management of plant parasitic nematodes is essential. Rootknot nematode management is primarily dependent on the application of chemical nematicides and the use of resistant varieties. However nematicide application is often done uniformly regardless of the relative nematode distribution in the farms, and yet ...

Efficiency Of Macropropagation In Relation To Other Banana Seedling Production Methods In Different Agroecologies In Central And Eastern Kenya

Bananas and plantains (Musa spp.) are amongst the most important tropical fruit crops and are staple foods in most parts of the humid tropics and important sources of income to small scale holders in rural areas. In Kenya, banana is grown as an important food and cash crop. However, its cultivation has largely remained small scale. A common limiting factor to large scale production and expansion of existing plantations is the difficulty in obtaining high quality planting materials. Natu...

Lime And Manure Application To Acid Soils And Their Effects On Bio-Chemical Soil Properties And Maize Performance At Kavutiri - Embu County

Soil acidity is widespread globally, accounting for about 40% of total arable soils. In Kenya, acid soils cover about 13% of total land area and are distributed widely in the croplands of central and western Kenya regions, covering over one million hectares. The main limitation of crop productivity in Kavutiri, Embu, is soil acidity and more specifically aluminium toxicity. The objective of this study was to determine the effects of agricultural lime in combination with farmyard man...

Effects Of Rhizobial Inoculation And Phosphatic Fertilizer On Soil Chemical Properties, Growth And Yield Of Sorghum - Cowpea Intercrop In Eastern Kenya

Agriculture is the dominant source of livelihood in rural areas of sub-Saharan Africa. However, in semi-arid eastern Kenya, smallholder farm productivity has been diminishing due to declining soil fertility and frequent droughts. Nitrogen (N) is the principal nutrient element limiting crop productivity in the region, followed by phosphorus (P). The use of N fixing legumes in intercrop with cereal crops is among the cheaper-viable options available for the resource-constraint farmers to ...

Effect Of Cattle Manure, Mineral Fertilizer And Rhizobium Inoculation On Climbing Beans Production And Soil Properties In Burera District, Rwanda.

Agriculture is the major engine of Rwandese economy, accounting for about 40% of the GDP, 85% of employment and 80% of exports. Known as “meat for the poor”, beans constitute a predominant source of proteins in Rwandese diet since they supply 65% of national dietary proteins compared to 4% from animal sources. However, the on-farm bean productivity is about 0.8 – 1.0 tons/ hectare which is quite low compared to 5 tons/hectare that is achieved under optimal management condition...

Analysis Of Technical Efficiency Of Smallholder Sorghum Producers In Machakos And Makindu Districts In Kenya

Majority of the rural households in Kenya depend mainly on agriculture as a source of food and livelihoods. Agricultural productivity has been declining due to many factors including climate change. Declining agricultural productivity has in turn resulted in increased food insecurity in the country. Consequently, there is a renewed interest in promoting drought-tolerant crops such as sorghum, which are known to perform well in the arid and semi-arid lands of the developing world. Owing ...

Socio-Economic Factors Influencing Smallholder Pumpkin Production, Consumption And Marketing In Eastern And Central Kenya Regions

Pumpkin is an indigenous vegetable with huge potential to provide nutrition, food security and income to households in Kenya but its production remains low. The crop has been given little attention in research and has not been promoted as a viable enterprise. Literature indicates that socio-economic factors and farming constraints in pumpkin production, consumption and marketing by smallholder farmers in Eastern and Central Kenya have not been studied nor documented. This research w...

Effects Of Different Organic Residues On Carbon Sequestration, Nutrient Availability In Soil And Maize Yields At Katumani, Machakos County, Kenya

Reduced farm productivity in smallholder farms is the principal cause of food insecurity in semi- arid parts of Kenya. This is mainly attributed to soil fertility depletion, land degradation, low soil moisture and climate change. Climate change due to increased carbon dioxideemission into the atmosphere has impacted negatively on the food productivity in Africa. The objectives of this study were: 1) to determine the effect of different organic residues on soil carbon accumulation in...

Evaluation Of Grafting Technology For Management Of Bacterial Wilt (Ralstonia Solanacearum) Of Tomato (Solanum Lycopersicum L)

Tomato (Solanum Lycopersicun L) is a very important vegetable grown mainly by small scale farmers in most arable areas in Kenya. Tomato production has declined drastically due to attack by Ralstonia solanacearum, a soil borne pathogen which causes bacterial wilt. Transmission of pathogen occurs when bacterial ooze from the plant enters the surrounding water or soil, contaminates farming equipment or by insect vectors. The disease has not yet been effectively managed. Grafting is an asex...
