Effects of Agricultural Lime Types on Soilproperties and Maize (Zea Mays L) Performance in Soils of Tharaka Nithi County, Kenya
(Kenyatta University, 2018-11)Soil acidity is a widespread problem affecting 40% of total arable land globally and about 13% of Kenyan total land area. Acidic soils are generally infertile with limited plant growth due to buildup of Al3+, H+,Fe2+, and ... -
Effect of Phosphorous and Rhizobia Inoculation on Growth and Yield of Desmodium and Lucerne in Kiambu County, Kenya
(Kenyatta University, 2018-11)Integration of legumes into farming systems is one of the Integrated Soil Fertility Management options for improving soil fertility. Farmers can increase their production by using legumes (desmodium and Lucerne), which, ... -
Path and Stability Analyses of Yield and Yield Components of Soybean (Glycine Max. L Merr.) Varieties Intercropped with Maize
(Kenyatta University, 2018-07)Soybean production in Kenya is estimated at 9,061MT. This is low compared to the annual demand of 100,000MT. This large deficit is met through importation which puts a strain to the economy’s foreign exchange. Soybean has ... -
Soil Nematode Communities under Organic and Conventional Farming Systems in Chuka, Tharaka Nithi County, Kenya
(Kenyatta University, 2018-10)Plant parasitic nematodes (PPN) are biotic constraints to crop production worldwide resulting in significant yield losses. Management of these nematodes has primarily depended on chemical nematicides; but due to the ... -
Effects of Rhizobia Inoculation and Phosphorus Levels on Soybean (Glycine Max L.Merril) Yields and Selected Soil Properties in Embu County, Kenya
(Kenyatta University, 2018-11)Soybean (Glycine max L. Merril) productivity in Kenya is adversely affected by low yield, poor fertilizer use, ineffective inoculation, and soil fertility management constraints. The empirical understanding of the interaction ... -
Evaluation of Nutrient Management for Improved Nitrogen Use and Agronomic Efficiencies in Rice (Oryza Sativa L.) in Kisumu, Busia and Kirinyaga Counties, Kenya
(Kenyatta University, 2018-11)Nitrogen is a major mineral nutrient limiting growth, development and production of crops in Kenya. The cost of production is way beyond the purchasing power of smallholder farmers, coupled with the low availability of ... -

(Kenyatta University, 2018)Nitrogen is a major mineral nutrient limiting growth, development and production of crops in Kenya. The cost of production is way beyond the purchasing power of smallholder farmers, coupled with the low availability of ... -
Assessment of Agronomic Performance and Haploid Induction Rate of Tropically Adapted Inducer Maize Lines
(Kenyatta University, 2018)Hybrid maize varieties are developed using inbred lines. Conventionally, inbred lines are developed by self-pollination, which takes 6-8 generations. The technology of doubled haploid (DH) is new and the most efficient in ... -
Occurrence of plant parasitic nematodes in commercial pineapple fields and effect of biocontrol agents on meloidogyne species in Kenya
(Kenyatta University, 2018-05)Plant-parasitic nematodes, in particular Meloidogyne spp., cause significant yield reduction in commercial pineapple (Ananas comosus) worldwide. In Kenya limited studies have been conducted on nematodes in pineapple although ... -

(Kenyatta University, 2018-05)Plant-parasitic nematodes, in particular Meloidogyne spp., cause significant yield reduction in commercial pineapple (Ananas comosus) worldwide. In Kenya limited studies have been conducted on nematodes in pineapple although ... -
Evaluation of row spacing and mulching on weed control, growth and yield of green pepper in Busia County, Kenya
(Kenyatta University, 2018-06)Green pepper (Capsicum annuum) is one of the most important and remunerative vegetable crops. Row spacing and mulching are important factors that influence water use, weed suppression, growth, quality, and yield of vegetables. ... -
Evaluation of grafting technology for management of bacterial wilt (Ralstonia solanacearum) of tomato (Solanum lycopersicum L)
(Kenyatta University, 2018-04)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 ... -
Effects of leaf extracts, organic, inorganic fertilizers on soil ph, growth, soil macronutrients, beta-carotene of amaranthus in Kiambu County, Kenya
(Kenyatta University, 2018-05)Soil is a significant reservoir for plant nutrients and hence necessary for plant growth. Soil pH is a very important chemical property of the soil, as it dictates the availability of plant nutrients. Low soil pH reduces ... -
Effect of organic and inorganic fertilizers on growth, yield and quality of amaranths in Kiambu County, Kenya
(Kenyatta University, 2018-07)An experiment was carried out for two seasons in Kiambu County to investigate the influence of organic and inorganic fertilizer on growth, anti-nutrients characteristics in amaranth species and the changes in the soil ... -
Effects of Nitrogen Forms on Growth, Yield and Nutritional Quality of Amaranth (Amaranthus Species) in Kiambu and Kirinyaga Counties, Kenya
(Kenyatta University, 2017)Amaranthus spp is amongst the most preferred African leafy vegetables in the tropics. It contains numerous vitamins, minerals and bioactive phytochemical compounds for nutritional and health benefits. Nitrogen is a vital ... -
Effects of gibberellic acid and cytokinin application on morphological development, growth, quality and yield of french beans grown under different irrigation schedules
(2017-07)French bean (Phaseolus vulgaris L.) is an increasingly important vegetable crop in Kenya accounting for a significant proportion of foreign exchange earned from horticulture. Farmers in Kenya experience insufficient and ... -
