Assessment Of Genetic Diversity Of Sorghum (Sorghum Bicolor) Accessions From Tanzania Using Ssr Markers: Implications For Conservation

Plant genetic resources are a key component of global biodiversity from which humanity derives most of its food and other essential goods and services. An understanding of the  extent, distribution, and patterns of genetic variation is useful for several purposes, including selection for conservation, estimation of any possible loss of genetic diversity prior to conservation programs, understanding the genetic variability available and its potential use in breeding programs, and estimating t...

Wind Resource Potential For Electricity Generation Using Micro - Hybrid Systems In Northern Kenya

ABSTRACT Currently the world is embracing renewable energy not only to enhance energy capacity but also to mitigate problems associated with green house gas emissions. North eastern Kenya region lagged behind others parts of the republic in social economic indices. This may be attributed to the fast distance between the region and the electricity generation areas. Therefore northern Kenya is not connected to national electricity grid. Renewable energy from the wind can be used to supply elec...

Effects Of Selected Limiting Nutrients On Growth And Yield Of Maize And Their Variability In Smallholder Farms Of Kandara, Murang’a County

ABSTRACT  Nutrient mining and mismanagement of farmers’ fields has led to a decline in soil fertility in smallholder farms. In order to increase the productivity and subsequently improve food security in Sub-Saharan Africa (SSA), there is a need to identify soil nutrients limiting maize growth and production. The objectives of the study were; (i) to determine the most limiting nutrients for maize production in Kandara and establish the effect of selected soil amendments (CaMgS, manure and ...
