Effect of Land Use Types on Selected Physical and Chemical Properties of Ultsiols in Umudike, Southeastern Nigeria.

Akinmutimi A.L.*, Ogwuegbu T.U., Ernest U. Eteng

Field experiments were carried out in 2018 and 2019 at the National Root Crops Research Institute Eastern Farm, Umudike, Southeastern Nigeria to examine the different forms of potassium and their contributions toward potassium uptake under ginger production using ginger variety (UG 1) as the test crop. There were seven treatments consisting of sole...

Biofortification of Agricultural Effluents on Translocation and Accumulation of Micronutrients Content in Cucumber (cucumis Sativus) Plants Grown in a Coastal Plain Sand Soil South - South Ecological Zone, Nigeria

Ernest U. Eteng*

The study was conducted to evaluate the effects of agricultural effluents on Cu, Fe, Mn and Zn, partitioned in cucumber plants. Eight treatments, cassava mill effluent (CME), palm oil mill effluent (POME), poultry waste effluent PWE and their combinations were biofortified on cucumber plants. Samples were collected from the amended soils and plant ...

Effect of Simulated Acid Rain on Growth and Micronutrient Uptake of Okra (abelmoschus Esculentus) on Coastal Plain Sands in Abia State, South - Eastern, Nigeria

Ernest U. Eteng*, Essien G. E

The study was conducted in April 2019 at Umudike to examine the impact of simulated acid rain (SAR) and frequency of SAR spray on growth and micronutrients content of okra (Abelmoschus esculentus (L.) Moench) in an ultisol at Umudike. The treatments consisted of three (3) pH levels: Coca-cola solution (pH 2.7) and SAR (pH 3.5 and 5.5) as well as co...

Effects of Parent Material and Land Use on the Variability of Available Cu in a Wetland Soil Under Long - Term Farming System

Ernest U. Eteng*

The study was carried out in the dry season to evaluate the variation in available Cu in wetland soil under long-term farming systems. Twenty four surface (0-20 cm) composite soil samples of acidic nature were obtained and analyzed for available Cu in the soils using five extractants (0.01M HCl, Coca-cola, 0.05M EDTA, 0.05M DTPA, and 1N NH4OAc) res...
