    Abstract: To study the soils of Southern Highland Zone of Tanzania, four representative pedons of some landscapes were characterized. Their names and identifiers are Seatondale, Mbimba, Inyala, and Uyole, respectively TzSea 01, TzMb 02, TzIny 03, and TzUy04. The pedons were formed from the weathering of among other materials, colluvial igneous rocks, alluviu... Show More

    Abstract: [Context] Unpredictable water deficit (drought) and low soil phosphorus (LP) are major interacting constraints to groundnut growth and grain yield in Sahelian zones of West Africa. Combining breeding efforts for drought tolerance and P efficiency could lead to improve tolerance and grains yield in these zones. [Objectives] This study assessed six g... Show More

    Abstract: As one of the major foliar diseases, wheat powdery mildew caused by Blumeria graminis f. sp. tritici (Bgt) affects photosynthesis of nutrient organs, such as stems and leaves, causing a reduction in production to varying degrees. In recent years, it has been found that powdery mildew can also affect grain quality, including nutritional quality and ... Show More

    Abstract: Apple (Malus x domestica Borkh.), being self-incompatible, requires cross-pollination to set fruit regularly. Apple flowers contain ten ovules and the higher the number of fertilized ovules, the larger the fruit size. In commercial orchards, cross pollination is usually guaranteed by intercropping different cultivars and by introducing beehives in ... Show More
