(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 Phosphate Rates on Nitrogen Uptake, Growth, Yield and Quality of Finger Millet in Busia, Kakamega and Makueni Counties
(Kenyatta University, 2017-06)Finger millet (Eleusine coracana) is an important subsistence cereal grain grown mainly in the relatively marginal and dry areas of Kenya. The crop has particular relevance in food security as it is more resilient to abiotic ... -
Soybean(glycine max) response to rhizobia inoculation as influenced by soil nitrogen levels
(Kenyatta University, 2017-07)Inoculation of soybean (Glycine max) is an efficient and convenient way of introducing rhizobia to soil and subsequently the rhizosphere of the crop. However, its full potential in sub-Saharan Africa is yet to be realized ... -
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 ... -
Effect of selected bradyrhizobia and nutrients on cowpea biomass, biological nitrogen fixation and yield in Kilifi and Mbeere Regions of Kenya
(Kenyatta University, 2017-07)Cowpea cultivation in Kenya is practiced by smallholder farmers who use little or no inputs like microbial inoculants and fertilizer. This study was conducted to evaluate the effect of rhizobial inoculation and nutrient ... -
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)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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
