fumigant toxicity of various doses of essential oils (185.2, 370.4, 555.5, 740.7, 925.4, 1111.1, and 1296.3 µl/l water) from five officinal plants, including rosemary (rosmarinus officinalis), lavender (lavandula vera), fennel (foeniculum vulgare), tarragon (artemisia dracunculus)and summer savory (satureja hortensis)on two stored products pests, cowpea weevil (callosobruchus maculatus) and red...

A laboratory microcosm incubation was conducted to study the influence of mixed cowpea-maize residues on N2O emission and N mineralization in a tropical acrisol. The soils were incorporated with different ratios of cowpea:maize mixtures on weight basis: 100:0, 75:25, 50:50, 25:75 and 0:100, and a control treatment in which there was no residue incorporation. The results show that N2O and CO2 em...
