Biochar as an Alternative Growth Medium for Tree Seedlings in the Guinea Savanna Zone of Ghana

A good planting medium is required for raising tree seedlings in the nursery, however Guinea savanna soils are generally poor in nitrogen and organic matter. This poses a challenge in accessing fertile soil for tree nurseries in Northern Ghana. The experiment was conducted in the Nyankpala campus to explore the potential of plant biochar as growth media for raising tree seedlings. Growth media prepared from six different...

Evaluation of NPS Fertilizer on Yield and Economic Performance of New Variety of Hot Pepper (Capsicuaim annum) in Tanqua Abergelle, Central Tigray, Ethiopia

Hot pepper (Capsicum annum L.) is one of the major economically important horticultural crops in Tanqua-Abergelle district. However, its productivity is low mainly due to soil nutrient deficiency and the use of unappropriated rate of fertilizer Nitrogen (N), phosphorus (P) and Sulphur (S) are the most deficient elements in the area. The experiments were designed to study the effect of NPS levels accompanied with one level...
