Influence of adding edible termite flour to Ogi powder: its chemical and phytochemical composition
(2024-07-05)Ogi, a traditional staple food made from submerged fermented cereal grains, is high in carbohydrates and low in protein. It is essential to conduct this research because termite flour (TF) addition may affect other quality aspects in addition to increasing protein content. Using 100 g of Ogi powder as a control sample, the chemical and phytochemical content of Ogi developed from blends of Ogi powder (OP) (50–100 g) with termite flour (TF) (10–50 g) was assessed using standard methods. The average ... -
Effect of combined use of supplementary irrigation, manure and P fertilization on grain yield and profitability of soybean in northern Nigeria
(2024-04-14)Declining soil fertility particularly phosphorus deficiency, low organic carbon, moisture stress and high cost of input are factors limiting soybean yield in the Nigeria savanna. Supplementary irrigation, nutrient application and inoculation with Bradyrhizobium could increase the grain yield of soybean. We evaluated the effects of Rhizobia inoculant, phosphorus fertilization, manure, and supplementary irrigation on the nodulation and productivity of a tropical soybean variety in two locations in ... -
Agronomic and hormonal approaches for enhancing flowering intensity in white Guinea yam (Dioscorea rotundata Poir.)
(2023-10-09)Developing novel white Guinea yam (Dioscorea rotundata) varieties is constrained by the sparse, erratic, and irregular flowering behavior of most genotypes. We tested the effectiveness of nine agronomic and hormonal treatments to enhance flowering on D. rotundata under field conditions. Genotypes responded differently to flower-inducing treatments (p<0.001). Of the test treatments, pruning and silver thiosulfate (STS) were effective in increasing the number of spikes per plant and the flowering ... -
Determination of abundance and symbiotic effectiveness of native rhizobia nodulating soybean and other legumes in Rwanda
(2024-04)Rhizobia diversity in the rhizosphere is one of the key promoters of biological nitrogen fixation between host legumes and microsymbionts, although related complex interaction may depend on various factors. This research was intended to assess the abundance of indigenous rhizobia isolates under various soil conditions, as well as their effectiveness to nodulate legumes such as soybeans. Factors such as soil properties and legume species influence the volume and symbiotic effectiveness of native ... -
Genetic diversity of cassava landraces and documentation of farmer's knowledge in Lamu, Kenya
(2024)To develop a strategy for improvement of cassava (Manihot esculenta Crantz) productivity for climate change preparedness in Lamu County, Kenya, it was important to understand which cultivars farmers are growing. Landraces should be collected and conserved prior to replacement by improved cultivars to avoid erosion of genetic resources and associated farmer knowledge. In this study, 58 samples of landraces were collected from five administrative wards in Lamu County. These were SNP genotyped using ...
