Soil Properties and Cocoa (theobroma Cacao L.) Nutrient Uptake as Affected by Organic and Inorganic Based Fertilizers in Southwestern Nigeria

Adejobi K.B*, Agele S.O., Ewulo B. S.

Low soil fertility is a major problem for cocoa establishment on the field, however, cocoa (Theobroma cacao L) is characterized by high nutrient demand particularly N, P, K, Ca and Mg during its early growth. In this study, the effects of organic and inorganic fertilizers on soil properties and nutrient uptake of cocoa in Ibadan and Owena soils of Southwestern Nigeria were investigated in 2011. Th...

Cassava Yield as Affected by Sawdust Ash Siam Weed Residue and Npk Fertilizer

Babadele D.O.*, OJENIYI STEPHEN OLUSOLA

Experiment was conducted at Ayegunle and Oka South-West Nigeria to study effect of combined sawdust ash and siam weed residues and NPK fertilizer (NPKF) on soil nutrients and performance parameters of cassava. Plant parameters determined were number of leaves, plant height, stem girth, leaf area index, root weight, root diameter and root length. Plant residues NPKF and their combinations increased...

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...

Comparative Mineralogical Analysis of Epigeal and Arboreal Termite Nests using Modern Analytical Techniques

Olushola Sunday Ayanda, Sharhabil Musa Yahaya*, Omolola Helen Aremu, Aminu Abdullahi, Mohammed Adewumi Abdulrasak, Sa’adatu Eri Mohammed, Naseer Inuwa Durumin Iya, Augusta O. Mmuoegbulam, Abdulsalam I. Galadima, Micheal Abiodun Oluyide, Folahan A Adekola, Simphiwe M Nelana, Michael J Klink

Termites are generally known to be destructive to woody materials and are of benefit to agricultural sector as they improve the fertility of soil and recycle organic matter. Termite nests such as arboreal, epigeal, hypogeal amongst others are being built by termites and have received great attention due to its diverse complex architectural structures and its utilization by researchers for diverse ...

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...
