Suitable Image Features for Drought Stress Detection in Beans using Raspberry PI Imaging System
(International Journal of Innovations in Engineering and Technology, 2017)Crop stresses are often detected late and this leads to massive crop yield loss. There exists a need for development of a real time system for monitoring crop growth progress with a view of early detection of diseases and ... -
The Possibility of Angle Trisection (A Compass-Straightedge Construction)
(Journal of Mathematics and System Science, 2017)The objective of this paper is to provide a provable solution of the ancient Greek problem of trisecting an arbitrary angle employing only compass and straightedge (ruler).(Pierre Laurent Wantzel, 1837) obscurely presented ... -
The Cube Duplication Solution (A Compass-straightedge (Ruler) Construction)
(International Journal of Mathematics Trends and Technology, 2017)This paper objectively presents a provable construction of generating a length of magnitude;, as the geometrical solution for the ancient classical problem of doubling the volume of a cube. Cube duplication is believed to ... -
Antibiotic resistance of bacteria isolated from Nairobi River
(2006)This study aimed to evaluate the antibiotic resistance of bacteria isolated from six sites along the pollution gradient of Nairobi River. Bacteria were isolated by standard Methods and grouped into 3 categories; enteric ... -
Evaluation of nitrogen fixation using 15N dilution methods and economy of a maize-tepary bean intercrop farming system in semi-arid SE-Kenya
(Springer, Dordrecht, 2007)Tepary bean has become popular among poor small-scale farmers in semi-arid Kenya, where it is intercropped with maize. This study aimed at i) evaluating the N-economy of maize/tepary bean intercrop versus sale crop using ... -
FACTORS INFLUENCING ANTI-RETROVIRAL THERAPY UPTAKE AMONG HIV POSITIVE AND EXPOSED CHILDREN AGED BELOW 14 YEARS IN MERU NORTH DISTRICT, KENYA
(EAST AFRICAN MEDICAL JOURNAL, 2018)Anti-retroviral Therapy (ART) is a major intervention for children infected and exposed to HIV infection and it influences their morbidity and mortality.Objective: To investigate factors influencing ARV uptake in HIV ... -
Somatic embryogenesis and plant regeneration from immature embryos of tropical maize (Zea mays L.) inbred lines
(2008)Somatic embryogenesis and plant regeneration was achieved from immature embryos of six maize (Zea mays L.) inbred lines (CML216, CML78, CML331, TL18, TL27 and MU25). Callus was initiated on N6 medium supplemented with ... -
Biological nitrogen fixation by promiscuous soybean (Glycine max L. Merril) in the central highlands of Kenya: response to inorganic fertilizer soil amendments.
(IDOSI Publications, 2010)Biological nitrogen fixation (BNF) by promiscuous soybean cultivars offers a potential for minimizing the investment made by resource-limited farmers in central highlands of Kenya. Nitrogen fixation in this grain legume ... -
Low technology tissue culture materials for initiation and multiplication of banana plants
(African Crop Science Society (Uganda), 2010)Tissue culturing has become a routine method for propagating plants in high technology laboratories. The cost of production using conventional tissue culture is, however, high for most of the countries in the sub-Saharan ... -
Evaluating the macropropagation efficiency of banana varieties preferred by farmers in Eastern and Central Kenya
(Kenya Agricultural Research Institute, 2010)Kenyan farmers are threatened by overreliance on few crops whose yields are reduced by adverse climatic changes. Bananas are more resilient and produce year round, making it a more suitable crop. To increase banana production, ... -
Cassava production and limitation of propagation through tissue culture
(Contribution of Agricultural Sciences towards achieving the Millenium Development Goals, 2010)With the unrelenting increase in human population it is important that concerted efforts be made to increase crop productivity so as to match the expected increase in food demand. The gravity of this problem is well ... -
Nodulation and nitrogen fixation in promiscuous and non promiscuous soybean (Glycine max (L.) Merrill) varieties in Eastern Kenya
(Kenya Society of Microbiology, 2010)Soil nitrogen deficiency is a major factor limiting soybean production. This problem can be alleviated by the use of nitrogen fertilizers which on the other hand adversely affect the environment, are expensive and ... -
A low-cost medium for sweet potato micropropagation
(African Crop Science Conference Proceedings, 2011)Tissue culture has not been optimised in sweet potato (Ipomoea batatas (L) Lam) propagation due to high costs. With an aim of producing affordable disease-free seedlings, a low cost medium was developed and used to ... -
Banana distribution and their seed systems in central and eastern Kenya.
(African Crop Science Society, 2011)Bananas (Musa spp.) serve as food, income resource and animal feed in addition to other environmental benefits. In Kenya, the crop is mainly grown and managed by smallholder farmers. Over the last two decades, banana ... -
Material Properties of RE-Doped Ln (Ln= Y, La) oxides and oxysulfides phosphors for red-emitting devices
(University of the Free State, 2015)Structural and optical properties of Eu3+-doped Ln (Ln=Y, La) oxide and oxysulfide nano crystals synthesized by sol-combustion method were analysed as a function of host to fuel ratio. Structural characterization shows ... -
Variation in nitrogen fixation among three Bush Bean cultivars grown in Kenya when inoculated with three Rhizobia Strains
(Greener Journal of Agricultural Sciences, 2012) -
Response of Two Sweet Potato (Ipomoea batatas L. Lam) Varieties Regenerated on Low Cost Tissue Culture Medium
(David Publishing Company, Inc., 2012)Plant tissue culture continues to be of great interest within the realms of molecular biology, plant breeding and plant health. However, different plant cultivars have different culture efficiencies to tissue culture. In ... -
In vitro micropropagation of cassava through low cost tissue culture
(Maxwell Science Publishing, 2012)Adoption of drought-tolerant crops such as cassava can help alleviate food insecurity in sub-Saharan Africa. However, production is constrained by lack of disease-free planting materials. This can be circumvented through ... -
Managing soybean for enhanced food production and soil bio-fertility in smallholder systems through maximized fertilizer use efficiency
(Scientific & Academic Publishing, 2013)The production of promiscuous soybean by smallholder farmers in Kenya would improve soil fertility through biological nitrogen fixation (BNF), boost food security, and contribute to generation of cash. The present study ... -
Low cost tissue culture technology in the regeneration of sweet potato (Ipomoea batatas (L) Lam)
