Heavy Metal Accumulation in Soil and Subsequent Uptake by Amaranthus (amaranthus Cruentus (l.) Irrigated with Dye Industrial Effluent

O. A. Oguntade*, Adetunji M. T, Jamiu Oladipupo Azeez

This study assessed the impacts of untreated dye effluent collected from three dyeing sites on soil heavy metal accumulation, uptake by root and accumulation in amaranthus shoot. Dye effluents collected at discharge points on the sites were diluted with fresh water at 0 %, 25 %, 50 % and 100 % concentrations. Each dye effluent concentration was applied at the rate of 200 ml three times in a week t...

Effect of Poultry Manure on Soil Chemical Properties and Root Yield of Sweet Potato (ipomoea Batatas (l) Lam) Grown in a Tropical Ultiso

N. A. Onunka*, V.E. Osodeke, D. O. Asawalam

A field trial was conducted at National Root Crops Research Institute Umudike in 2004/2005 cropping seasons. The aim was to evaluate the effect of poultry manure applied over time intervals on some soil chemical properties and root yield of Sweet potato. The time intervals were 2 weeks before planting, (WBP), at planting, 2, 4, and 6 weeks after planting (WAP). Sweet potato varieties used were TIS...

Influence of Sesame Varieties and Fertilizer Levels on the Yield of Sesame in Potiskum, Yobe State - Nigeria

Usman, M.*, A. Ali, Olatunji O

Field experiments were carried out in 2018 and 2019 cropping seasons to deter- mine the influence of sesame varieties and fertilizer levels on the yield of sesame in the study area. Treatments consisted of three varieties of sesame (Jigida, NCRIBEN-01M and NCRIBEN-032) and four levels of NPK 15:15:15 fertilizer (0, 50,100 and 150 kg ha-1). Treatments were laid out in a randomized complete block de...

Micronutrient Status of Grain Size Fractions in Soils of Land Uses in Mbano, Southeastern, Nigeria

Uzoho B.U.*, Irokwe I. F.

Micronutrient status in grain size fractions provides information on the active soil fraction and the ability for stabilization against microbial decomposition. Total, available, exchangeable and water-soluble Fe, Zn, Cu and Mn in bulk and grain size soil fractions were evaluated in three land use types (Cassava, Cashew and Oil palm) in Ehime Mbano, Southeastern, Nigeria. Also, using correlation a...

Morphological and Physical Properties of Soils on Basement Complex in Northern Guinea Savanna of Nigeria

MANIYUNDA L.M.*, Bashiru Ademola Raji, Odunze Azubuike Chidowe, MALGWI W.B.

Soils developed on four basement complexes, namely Older Granites (OG), Quartzites (QZ), Mica Schists (MS) and Migmatite Gneiss (MG) were studied on crest position in Northern Guinea Savanna of Kaduna State, Nigeria with a view to examine their morphological and physical properties and suggest management options. The results indicated that parent materials significantly influenced soil depth, stru...
