Morphological traits associated with anthracnose (Colletotrichum lindemuthianum) resistance in selected common bean (Phaseolus vulgaris L.) genotypes
Common bean is among the most important legume crop for protein source in people’s diet globally and including Kenya. Anthracnose is a common disease of legumes that causes yield loss of up to 90-100%. The aim of the study is to investigate the morphological traits associated with anthracnose resistance in selected common bean genotypes in Kenya. The study was done in three varied agro-ecological zones; University...
Evaluation of the relative feed value of indigenous savanna forage shrub species in Ghana
Animal performance mainly depends on the quantity and quality of forage available as feed and animal feed represents one of the major costs in animal production. This research was conducted in the Faculty of Natural Resources and Environment Experimental Field at University for Development Studies, Nyankpala Campus to evaluate the relative feed value of four indigenous savanna forage shrubs. These shrubs were cultivated...
Expression of Cocculus hirsutus trypsin inhibitor promotes endogenous defensive response against Helicoverpa armigera and enhanced levels of antioxidants
Proteinase inhibitors are a group of defense related proteins, natural antagonists of proteinases, induced upon herbivory, play a defensive role against polyphagous insects and phytopathogens. Serine proteinase inhibitor isolated from Cocculus hirsutus (L.) Diels, Cocculus hirsutus trypsin inhibtor (ChTI) was found effective as antifungal, bactericidal and nematicidal agent. Tomato plants expressing ChTI have been...
Effects of severity of apical shoot harvest on growth and tuber yield of two sweet potatoes varieties
Leaf harvesting of sweet potato during vegetative stage is common in most parts of Liberia. There is little information on the effects of severity of apical shoot harvesting on tuber yield of sweet potato. Experiments were conducted in 2017 at the Federal University of Agriculture, Abeokuta to determine the effects of severity of apical shoots harvest on growth and tuber yields. Experiment consisted of two varieties...
Modulation in growth and development of potato (Solanum tuberosum L.) microtubers by different concentration of 6-benzyl aminopurine
Two potato varieties namely, kufri bahar and kufri surya were tested for in vitro tuberization response to a same culture medium supplemented with three levels of 6-benzly aminopurine (0.75, 1.5 and 2.25 mg/L) in a completely randomized block design. The study was conducted in the Central Potato Research Institute (CPRI), Modipuram, Meerut Campus, and India during the period of 2012 to 2013 and 2013-2014. The objective...
