Abstract: The use of chemical fertilizers as soil amendment has improved crop yields in sub-Saharan Africa successfully. Unfortunately, they appear to be expensive and readily unavailable to farmers. They are also believed to cause soil acidity, eutrophication and emit greenhouse gases. This current field experiment was carried out to evaluate the effect of blood meal from abattoir blood waste on soil chemical properties (pH, organic Carbon, total Nitrogen, available Phosphorus, and exchangeable Potassium), the concentration of macro elements (Nitrogen, Phosphorus, Potassium, Magnesium, Calcium) and microelements (Copper, Zinc, and Iron) as well as the growth and yield of African chili pepper relative to chemical fertilizer. The study comprised four treatments: blood meal, conventional NPK, combination of blood meal and chemical NPK, and control with five replications in a Randomized Complete Block Design (RCBD). The result showed that blood meal significantly improved the soil pH, organic matter content, total Nitrogen, available Phosphorus and exchange Potassium, and the concentration of macro and microelements in pepper relative to chemical fertilizer and control. Also, Blood meal in combination with chemical fertilizer significantly improved the soil pH, organic matter content, total Nitrogen, available Phosphorus and exchange Potassium, and the concentration of macro and microelements in pepper compared to the chemical fertilizer and control The study also revealed that the application of blood meal significantly resulted in 7.6%, 32.9% and 398.7% fruit yield increase relative to the combination of blood meal and chemical NPK, conventional NPK alone and control. The application of blood meal from abattoir blood waste can improve soil chemical properties, nutrient concentration, growth and yield of African Chili pepper under field conditions.

Abstract: Species belong to the genus Tuber (Pezizales, Ascomycota) are ectomycorrhizal (ECM) fungi that produce hypogeous fruiting establishing a symbiotic interaction with plant roots, mainly oaks and hazelnuts. Truffles are known as the gastronomically prized species, with a high market value, due to the expensive delicacies. Although these fungi are distributed worldwide, it has never been discovered in DPR Korea. In this study, we described about the first discovery of Tuber huidongense in DPR Korea. Based on the discovery of specimens of Tuber huidongense in DPR Korea which represents the first harvest of a true truffle in the country, a phylogenetic investigation was carried out to clarify the existence or otherwise of a complex of species around this truffle, hypothesized by various authors. A genetic analysis of all the ITS sequences available in public database was performed and it appeared very probable that two other species of Tuber (T. furfuraceum and T. lannaense) described in Far East Asia are later synonyms with T. huidongense. Therefore, their synonymization is proposed and the taxonomy of T. huidongense is clarified. From a geographical point of view, the species so far seems concentrated in South and East Asia. Its possible presence in Europe (Czech Republic) is considered doubtful to be confirmed.
