Enhancing Maize Grain Yield in Acid Soils of Western Kenya Using Aluminium Tolerant Germplasm
(2015-07-21)Abstract: Maize (Zea mays L.) is one of the world’s most important cereals and is a staple food for many people in developing countries. However, in acid soils (pH < 5.5), its productivity is limited by aluminium (Al) ... -
Optimization of Seed Potato Specific Density, Starch and Dry Matter Contents and Tuberization Capacity of Resultant Plants Through Integrated Irrigation, Nitrogen and Phosphorus Management
(Journal of Plant Sciences, 2015-07-30)A study was conducted in a Rainshelter (RTrial) at the Horticultural Research and Teaching Farm of Egerton University to determine the effect of integrated application of irrigation water, nitrogen (N) and phosphorus (P) ... -
Sequentially partitioned population attributable fraction as an estimate of impact of tick presence on infection
(2015-08-21)he impact of Rhipicephalus appendiculatus tick presence (exposure) on Theileria parva infection seroprevalence (outcome) on a farm was assessed in a group of cattle using population attributable fractions (PAF). The ... -
Comparison of soil phosphorous extraction by Olsen and double acid methods in acid soils of Western Kenya
(2015-08-21)hosphorous is an essential nutrient in plants required for root establishment. In the soil, it is applied as DAP, TSP or phosphate rocks. In acid soils, aluminium and iron are dominant and tend to “fix” phosphorous, ... -
Phosphorus Sorption and Lime Requirements of Maize Growing Acid Soils of Kenya
(2015-08-21)In Kenya, maize (Zea mays L.) is mainly grown on acid soils in high rainfall areas. These soils are known for low available phosphorus (P), partly due to its sorption by aluminium (Al) and iron oxides. The study ... -
Development of maize single cross hybrids for tolerance to low phosphorus
(2015-08-21)Low available phosphorus (P) is one of the major hindrances to maize (Zea mays L.) productivity in acid soils. The objectives of this study were to: (1) develop P-efficient maize inbred lines, (2) develop single cross ... -
Immediate and residual effects of lime and phosphorus fertilizer on soil acidity and maize production in western Kenya
(2015-08-21)Soil acidity and phosphorus (P) deficiency are some of the major causes of low maize yields in Kenya. This study determined the immediate and residual effects of lime and P fertilizer on soil pH, exchangeable aluminium ... -
Teaching and Learning Resources as Determinants of Students Academic Performance in Secondary Agriculture, in Rachuonyo North Sub County, Kenya
(International Journal of Advanced Research, 2015-09)In the last decade, performance of students in Rachuonyo North Sub County has taken a downward trend in the national examination, Kenya Certificate of Secondary Education (KCSE).This downward trend is particularly seen in ... -
Economic efficiency of green maize intercropped with beans grown under Tithonia and inorganic fertilizer
(African Journal of Agricultural Research, 2015-11-20)A field trial aimed at assessing the performance of maize and beans under intercropped systems was conducted in 2013 under three experimental components of maize, beans and maize-bean intercrop in a randomized complete ... -
Seed Potato Growth, Harvest Index and Net Economic Benefit Improvement through Irrigation Water, Nitrogen and Phosphorus Management
(Columbia International Publishing American Journal of Agricultural Science and Technology, 2016)A study was conducted in a Rainshelter (RTrial) at Egerton University to determine the correlation between irrigation water, nitrogen (N) and phosphorus (P) application on seed potato growth, harvest index (HI) and net ... -
Occurrence and estimated losses caused by cassava viruses in Migori County, Kenya
(African Journal of Agricultural Research, 2016)A farm survey was conducted in Kuria East and Suna West sub-counties to determine the incidence, severity and estimated losses of cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) on cassava crops in ... -
Improving Seed Potato Leaf Area Index, Stomatal Conductance and Chlorophyll Accumulation Efficiency through Irrigation Water, Nitrogen and Phosphorus Nutrient Management
(Journal of Agricultural Studies, 2016)A study was conducted in a Rainshelter (RTrial) at Horticultural Research and Teaching Farm, Egerton University to determine the effect of integration of irrigation water, nitrogen (N) and phosphorus (P) application on ... -
Occurrence and estimated losses caused by cassava viruses in Migori County, Kenya
(African Journal of Agricultural Research, 2016)A farm survey was conducted in Kuria East and Suna West sub-counties to determine the incidence, severity and estimated losses of cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) on cassava crops in ... -
Performance of Leucaena leucocephala, Seedlings in Two Agro-climatic Regions of Kenya
(Journal of Agriculture and Ecology Research International, 2016-02-17)A study was conducted to determine the response of Leucaena seedlings planted in two variant agro-climatic regions, Chepkoilel Campus and Maseno in Kenya. The experiment was a 2-factor (provenance – site) split plot ... -
Inheritance of maize phosphorus efficiency in acid soils of western Kenya
(International Journal of Information Research, 2016-04)Soil acidity is a major constraint to maize (Zea mays L.) productivity in tropical soils due to toxic levels of aluminium (Al) and phosphorus (P) deficiency.Selection for acid-soil tolerance is a sustainable way for ... -
