Nutrient element losses in runoff and eroded sediments were monitored during 1972 on different slopes and under different soil and crop management treatments. The experiments were conducted on 25 x 4 m field runoff plots, established on natural slopes of 1, 5, 10 and 15%. The soil and crop management treatments consisted of bare fallow (plowed), maize-maize (plowed and mulched), maize-maize (plowed), maize-cowpeas (no-till), and cowpeas-maize (plowed). Total loss of nutrient elements in runoff and eroded soil materials was significantly affected by slope and by soil and crop management treatments. Total annual nutrient element losses in runoff were 55 Kg/ha for bare-fallow, 17 Kg/ha for maize-maize (plowed), 12 Kg/ha for cowpeas-maize (plowed), 2.3 Kg/ha for maize-maize (plowed and mulched) and 4.3 Kg/ha for maize-cowpeas (no-till). The concentration of nitrate in seepage water was two or three times higher than in surface water. Nutrient losses in eroded soil materials from the mulched and no-till treatments were negligible. From the plowed treatments, greatest losses were of organic matter and total nitrogen. The enrichment ratios were 2.4 times for organic carbon, 1.6 times for N, and 5.8 times for available phosphorus. |

Biofortification is a method that improves the nutritional value of food crops through conventional plant breeding. The aim of this study was to evaluate the effects of intra-amniotic administration of soluble extracts from zinc (Zn) biofortified and Zn standard cowpea (Vigna unguiculata L. Walp.) flour on intestinal functionality and morphology, inflammation, and gut microbiota, in vivo. |
