 Abstract

Influence of interaction between Ipomoea asarifolia L. (Desr.) and Cynodon dactylon (L.) Pers. on soil physical properties was investigated at Biological Garden, Usmanu Danfodiyo University Sokoto Nigeria. Soil samples (0-20 cm depth) were collected before and after the experiments and analyzed using appropriate field and laboratory techniques. The data obtained were subjected to statistical analysis using SAS statistical package (SAS, 2003). Results have shown improvement in soil texture from sand to loamy sand, with significant increase (P< 0.05) in silt (8.23 to 10.52%), clay (2.07 to 4.05%), porosity (19.40 to 28.50%) and particle density (2.17 to 2.24%) under I. asarifolia inhabited soil. Similar treatment with C. dactylon had also improved the soil texture from sand to loamy sand particularly under thick Cynodon cover, with significant increase (P< 0.05) in soil moisture content. Soil moisture content increased significantly (P< 0.05) (1.83 to 2.25%), along with particle density (2.17 to 2.24 mgkg-1). Interaction of the soil particles with mineral nutrients in the soil and organic matter deposits from the two cover crops may have improved the soil physical properties including aggregate stability, aeration, infiltration and water holding capacity. Maintaining a mixture of the two cover crops between cropping seasons is therefore recommended in the study area for improvement of the soil properties and sustainable agricultural productivity.
