Drought is a serious environmental stress limiting growth and productivity in peanut and other crops. Nutrient uptake of peanut is reduced under drought condition, which reduces yield. The objectives of this study were to investigate nutrient uptake of peanut genotypes in response to drought and to estimate the relationship between nutrient uptake and peanut yield under different water regi...

Leaf nutrients of sugarcane variety N16 are discussed and reasons for certain trends put forward. The fertilised versus non-fertilised treatment comparison showed that although where fertiliser was applied that leaf N, P and K were higher, Mn was also higher but Ca, Mg, Si, Zn and Fe were all lower. The trashed versus burnt treatments had a less drastic effect on leaf nutrient levels and it was...

Lake Tanganyika’s many endemic species are under threat by impacts from human development and land use changes. Anthropogenic sediment inputs into the lake have increased, with a suite of negative effects on the benthic fauna. Sedimentation reduces habitat heterogeneity, alters cycling of nutrients, interferes with visibility, and interferes with photosynthesis. For fauna of the rocky benthos, ...

Eriophorum spp. are abundant perennial graminoids in the Arctic tundra and boreal peatlands. Because ecological studies indicated that some plants are unusually productive on infertile and cold sites, the anatomy of the overwintering corms of Eriophorum vaginatum (L.) and Eriophorum scheuchzeri (Hoppe) were examined to determine their involvement in nutrient uptake and storage. Components of th...

Research on cycle infrastructure preferences generally suggests a preference for off-road cycle infrastructure and segregation from motor traffic, among both existing cyclists and non-cyclists. However, studies have so far not explored how the presence of children might shape adults’ attitudes to cycle infrastructure. Similarly, studies on the determinants of child cycling have not as yet looke...
