Soil Vulnerability and Degradation Assessment of Mountainous Area in Ekoli - Edda, South - East Nigeria

Ekpe, I I*, Oludare C. G,, Oti, N.N, Ishiusah O. W,, Egboka, N.T, Amarachi Orji, Nwankwo V.C.

Soil vulnerability and degradation assessment of the mountainous area in Ekoli-Edda, South-East Nigeria was carried out on four experimental sites namely Egu, Ugwuelu 1, Ugwuelu 2, and Ocha. The slope of each study site was divided into three namely summit, mid-slope, and foot slope, and slope attributes were measured. Two profile pits were sunk eq...

Effect of Time of Seed - Bed Preparation on Soil Properties and Performance of Water Yam in Owerri Southeast, Nigeria

Ekpe, I I*, Oti, N.N, Ishiusah O. W,, Egboka, N.T, Nwankwo V.C., Iheka, W. C, Aguwa, O U, Amarachi Orji

Field experiment was conducted between the months of February and November, 2016 to evaluate the effect of age of seed-bed preparation on soil properties and performance of water yam in Owerri, southeastern Nigeria. Treatments consisted of four time of seed-bed preparations namely 0, 3, 6, and 9 weeks intervals, laid out in a randomized complete bl...

Yield Decline Trends of Eroded Ultisols in Owerri, Southeastern Nigeria: Maize Response to Artificial Erosion

Oti, N.N*

The artificial incremental removal of surface soil to varying depths to simulate erosion followed by subsequent evaluation of crop growth and performance under uniform management is a common agronomic technique to study erosion/soil productivity relationships. However, because its results tend to exaggerate yield decline rates it is being replaced ...

Yield Decline of Major Crops Induced by Erosion on the Ultisols of Owerri, Southeastern Nigeria: Maize Response to Natural Erosion

Oti, N.N*

Few studies have been made to quantify the yield decline trends of major stable crops induced by erosion (natural and artificial) on the ultisols of Southeastern Nigeria, it is known that erosion’s impact on soil productivity is crop, environment and soil specific. This paper reports an aspect of a larger body of research work conducted between 199...
