Effect of NPK and poultry manure on selected soil properties, and performance of snake tomato (Trichosanthes cucumerina) in Wukari, Taraba State, Northeastern Nigeria

Waziah Y.*, JOHN WAMARHYEL GUNDIRI

This study was conducted to investigate the effect of NPK and poultry manure (PM) on selected soil properties and performance of snake tomato. The experiment was laid out in a randomized, complete block design with four treatments and three replicates. The treatments are 240 kg/ha NPK 15:15:15, 20 tons/ha PM, 120 kg/ha NPK 15:15:15 + 10 tons/ha PM, and control. The soil was loamy sand with low OC,...

Use of erodibility indices in assessing soil erosion in central and northern Cross River State, Nigeria

Akpa E A*, Okon P O, Abam P O, Sunday L. K

Soil erodibility indices were used to assess erosion prone areas in central and northern Cross River State, Nigeria. Fourteen (14) composite soil samples were collected at a depth of 0-30 cm and analyzed using standard laboratory procedures. Results showed that the soils are coarse textured with high sand content dominated by textural class of loamy sand in both the central and northern. The vulne...

Soil structure stability and organic carbon distribution along the toposequence of Orumba North in derived savannah of the South-East, Nigeria

Jidere, C.M.*, Ezeokoye, C.S., Obalum, S.E., Ukaegbu, E. P

In high-rainfall zones with severe water erosion problems, soil structure stability as promoted by soil organic carbon (SOC) should be prioritized. Landscape positions and land use influence soil properties and nutrient distribution. This study assessed soil structure stability and SOC content at top-slope, mid-slope and low-slope positions of a toposequence at Orumba North in derived savannah zon...
