Tuber Production of Cassava at Different Plant Spacing and Subsequent Effect on Soil Physical and Chemical Properties

Adeniyan O. N.*

The study aimed at identifying the influence of different plant population (plant spacing) on cassava tuber yield and the cumulative residual effect on soil physical and chemical properties were carried out in two cropping seasons (2008/2009 and 2009/2010) at Orin Ekiti research station of the Institute of Agricultural Research and Training (IAR&T), Moor Plantation Ibadan. The highest percentage c...

Effects of Arbuscular Mycorrhiza and Fertilizers on Soil Chemical Properties, Growth and Fibre Yield of Kenaf (hibiscus Cannabinus Linn.) in a Nutrient Degraded Soil

Bada B. S*

This study determined effects of fertilizers and Arbuscular Mycorrhizal (AM) inoculation on soil chemical properties, growth and fibre yield of kenaf. The experimental design was split-plot in Randomized Complete Block Design. Mycorrhizal inoculation was the main plot: with mycorrhiza (M+) and without (M-) and twelve fertilizer levels as the sub-plot: 0, NPK 20:10:10 (60 kg N ha-1), purely compost...

Effects of Land Use on Soil Micronutrients Status in Ughoton Community Ovia North East, Edo State, Nigeria.

P.O. Oviasogie*, Awanlemien B. E., Ikyaahemba P. T.

The study was conducted to assess the effects of different land use practices on soil micronutrients in 18 soil samples collected at 0-15 cm and 15-30 cm depth respectively from three land use types (Cassava field, Oil palm and Banana plantation) and analyzed for physico-chemical properties and selected micronutrients (Zn, Cu, Fe and Mn) using standard laboratory methods. The results showed that O...

Prediction of Saturated Hydraulic Conductivity Using Soil Texture and Organic Carbon Under Different Land Use Types

Onasanya, O. O*, F.K. Salako, AJIBOYE G. A., Busari M. A.

The aim of this study is to develop models for saturated hydraulic conductivity (Ks) in soils under different land use types in a tropical environment. The regression models were developed using the soil particle size fraction and organic carbon contents.The results indicated that the sand, clay and organic carbon content of the soils were sufficient in predicting the Ks. Also, there was a signifi...

Forms of Primary Nutrient Elements in Soils Overlying Contrasting Parent Materials in South - Eastern Nigeria

Ahukaemere, C.M.*, Bethel Ugochukwu Uzoho, Ndukwu, B., Onwudike S,U., Okoli N.H., Irokwe I. F.

Appropriate management of soil fertility should rely upon sound knowledge of the nutrients reserve and their availability. This is only possible if there is adequate information on the influence of parent material on the dynamics and availability of these nutrient elements. Research was carried out in 2014 at three locations underlain by three different parent materials namely Basalt (Ikom in Cros...

Effect of Goat and Poultry Manure Application on Selected Soil Properties and Yield of Garden Egg (solanum Melongena) on Acid Sand of Akwa Ibom State of Nigeria.

Okon, E. Udoh*, Usoro, I. E, Effiong, G. S.

Field research was conducted at the University of Uyo Teaching and Research Farm in 2003 to determine the effect of goat and poultry manure application on selected soil Physico-Chemical properties, and yield of garden egg (Solanum melongena).The experiment was laid out in a Completely Randomized Design (CRD) with four replicates. Animal manure treatments were applied at 4 levels, Control [O t/ha],...

Distribution of Forms of Potassium in Soils Cultivated to Shea (vitellaria Paradoxa C.f. Gaertn) Trees at Bida, Niger State, Nigeria

OSAYANDE P.E.*, P.O. Oviasogie, Orhue, Ehi Robert, Udoh, J. J

The distribution of potassium forms was studied at Bida, Niger state as part of the Shea butter tree domestication effort of the Nigerian Institute for Oil Palm Research. Soil samples were obtained with the aid of a soil auger at 0-15 and 15-30 cm. The soil samples were air dried, sieved with a 2 mm sieve and analyzed for some physical, chemical and potassium forms using standard methods. Results ...

Variations in Soil Properties as Influenced by Land Use and Soil Depth in a Derived Savannah Ecology of Southwestern Nigeria.

Denton O.*, Ogunkunle, A, Fademi I.

Soil physical and chemical properties are strongly influenced by soil management systems and changes in land use. The study was carried out in Iseyin LGA of Oyo state which is a derived savannah zone under four different land use types’ arable, grazing, fallow and tree crops. A total of twenty four soil samples were collected at two depths i.e. 0-15cm and 15-30cm, from the study area using the clu...
