This paper reports the field evaluation of the effect of tillage [tilled (MT) and untilled, (NT)], mulching material [Panicum maximum (p) and Chromolaena odorata (c)] and mulching method [incorporated (b), surface (s) and no mulch (o)] on soil properties and growth and yield of cowpea (Vigna unquiculata) in 2000 and 2001 cropping seasons, in Akwa Ibom State, Southeastern Nigeria. The study was a three-factor factorial in randomize complete block (RCB). The soil in 2000 and 2001 was strongly acidic. Organic C increased by about 83.6% at harvest in 2000 and declined by 16.4% in 2001. Available P declined by about 15.9% in 2000 and 59.6% in 2001. Base saturation increased by 9.6% in 2000 and decreased by 6.8% in 2001. Tillage and mulching practices improved water-stable aggregates >2mm by 16.6% in 2001. Bulk density was similar between MT and NT in 2000, but significantly lower (P Agro-Science Vol. 7 (2) 2008: pp. 118-128
