Stem anatomical features of four Sesbania Scop. species viz. S. bispinosa (Jacq.) W. Wight, cannabina (Retz.) Poir., sesban (L.) Merr., and rostrata Bremek. & Oberm., were examined to add some insights for identification these using quantitative descriptors. stem is composed epidermis, cortex, vascular tissues – phloem, cambium zone xylem, pith, which exhibit significant variations among th...

We hypothesized that the integration of trees into agricultural land-use systems can reduce NO., leaching and increase subsoil N utilization. A field study was conducted on a Kandiudalfic Eutrudox (Ochinga site) and a Kandic Paleustalf (Muange site) in the subhumid highlands of Kenya to measure changes in soil NO, and water to 200-cm depth for one rainy season in four land-use systems (LUS): (i...
