The purpose of this descriptive study was to assess pedagogical competency needs of agriculture teachers in Senior High Schools in Tamale aimed at determining their perceived level of importance, ability, and most suited training needs based on Borich’s Needs Assessment Model. To keep Senior High School agriculture teachers up-to-date of their pedagogical competency needs, the professional development needs of the agriculture teachers must be assessed regularly for efficiency. Based on the ...
The government of Ghana and Non-governmental Organizations have constructed a number of small scale irrigation dams and dug-outs in the Sissala West District of the Upper West Region. The purpose of the small scale irrigation dams is to give irrigation farmers access to enough water during the dry season. The variation of rainfall and high temperatures poses serious threat to dams, hence making it difficult for the reservoirs to have enough water for irrigation activities. The study investiga...
Abstract Background: Peasant agroecosystems in Kenya are considered to be a continuum of integrated traditional farming systems and natural ecosystem conservancy programs. Hyphaene compressa (doum palm) exists in arid and semi-arid lands (ASAL) of Kenya. While research in these areas is focusing on new plants to be brought to the areas, there is no focus on doum palm, which is already adapted to these areas. Scanty ethnobotanical knowledge exists in the form of unpublished material. The stud...
Abstract/Overview Over 6% of agricultural land is affected by salinity. It is becoming obligatory to use saline soils, so growing salt-tolerant plants is a priority. To gain an understanding of the genetic basis of upland cotton tolerance to salinity at seedling stage, an intra-specific cross was developed from CCRI35, tolerant to salinity, as female with Nan Dan (NH), sensitive to salinity, as the male. A genetic map of 5178 SNP markers was developed from 277 F2:3 populations. The map sp...
Abstract Named after Hermann L. F. von Helmholtz (1821-1894), Helmholtz equation has obtained application in many elds: investigation of acaustic phenomena in aeronautics, electromagnetic application, migration in 3-D geophysical application, among many other areas. As shown in [2], Helmholtz equation is used in weather prediction at the Met O ce in UK. Ine ciency, that is the bottleneck in Numerical Weather Prediction, arise partly from solving of the Helmholtz equation. This study investig...
Abstract/Overview Cotton is a moderately salt-tolerant crop, but its salt tolerance threshold is not more than 7.7 ds•m−1. The seedling stage of cotton is the highly sensitive to salinity and the effects can be quantified by measuring morphological and physiological traits. The purpose of this study was to identify QTLs related with salinity tolerance at seedling stage. Meanwhile where they were localized in the genome, investigate the relationships between the traits at seedling stag...
Abstract Aims: The aim of this study was to determine the effect of different watering regimes on selected coffee genotypes and to evaluate drought tolerance among selected coffee genotypes. The study also aimed at determining the optimum watering interval for these genotypes under high temperature conditions. Study Design: Completely Randomized Design (CRD) with 3 replications. Place and Duration of Study: The experiment was conducted in a greenhouse at Coffee Research Station in Ruiru, Ken...
Abstract African nightshade, Solanum nigrum L .is one of the most important leafy vegetable rich in nutritional and medicinal value, can be used to feed people with human immune deficiency virus, HIV/AIDS in Kenya. This study was conducted to morphologically characterize thirty African nightshade accessions in order to establish the level of genetic variation amongst them. The limited information available on this species hinders their sustainable conservation and development. Existing knowl...
Abstract/Overview Soil acidity is a major constraint to crop production on highly weathered tropical soils characterized by high Aluminum (Al) toxicity, low cation exchange capacity, and low phosphorus (P) availability to plants. The objective of this study was to evaluate the effects of two powdered limes (calcium oxide, calcium carbonate), granulated lime (CaO.MgO), and their combinations with mineral fertilizer on soil chemical properties (soil pH, organic carbon, exchangeable acidity,...
Abstract/Overview We examined the socio-cultural practices on the use of beetle grubs as food and feed in western Kenya by interviewing 211 randomly selected households and conducting seven focus group discussions in Bungoma, Kakamega, Busia, and Trans Nzoia counties. The grubs were used as food and feed in ~ 39% and 78% of the households, respectively. The perceived benefits of the grubs for human consumption were nutritiousness and no linkage to allergies. The grubs were perceived t...
Abstract/Overview This study was carried out to analyze mycotoxins of entomopathogenic fungi of fall armyworm (Spodoptera frugiperda J.E. Smith) and poultry feed safety. An experiment was set up to assess the types of mycotoxins produced by entomopathogenic fungal parasite of fall armyworm larvae and their subsequent efect on the safety of the larvae as a feed ingredient. Molecular characterization was done to estimate the diversity of entomopathogenic fungi on fall armyworm larvae specim...
Abstract/Overview Lake Flies are edible insects with the potential of contributing to food security in that they are an alternative protein and micronutrient food source in freshwater lake regions. The main challenge in exploiting the lake flies is the difficulty in the collection. This study was conducted to identify sustainable traditional collection practices and forecasting techniques of lake flies and was implemented in Rusinga and Mfangano Island in Kenya. The ethnographic study emp...
Abstract/Overview Ruspolia differens Serville (Orthoptera: Tettigonidae) is a highly nutritious and luxurious insect delicacy that is consumed as a food source in many African countries. However, the nutrient profile of R. differens in different geographical regions have received limited research interest. Here, we provide comprehensive evidence of geographical impact on the nutrient profile of R. differens and its potential to meet the recommended dietary intake of the population. Our ...
Abstract/Overview The utilization of edible insects as food and feed is not a new concept, it is a practice that has been part of the tradition of many communities around the world. They have been primarily used as supplementary food in most African countries. However, there has been a significant decline in the consumption of insects over the years, especially among young people. Therefore, this study aimed to investigate the knowledge on entomophagy and the utilization of insects among ...
Abstract/Overview Sweet potato (Ipomoea batatas L.) is a starchy, tuberous root with worldwide consumption. Production of sweet potatoes in Kenya is low due to disease constraints, such as fungal sweet potato leaf spot (SPLS), which is not well studied in the region. The infection results in reduced photosynthetic leaf area through premature defoliation and senescence. Effective management of SPLS presents an opportunity for increased production, improved food security and enhanced income...
