Effect of Groundnut (arachis Hypogea )residues on Soil Chemical Properties in the Sub - Humid Southern Guinea Savanna Zone of Nigeria

Achor O.I.^*, S.A. Ayuba, A. Ali

This study was conducted at the University of Agriculture Makurdi Research Farm in the Sub- Humid Southern Guinea Savanna zone of Nigeria during 2008 and 2009 cropping seasons to determine the effect of groundnut (Arachus hypogea) residues on the growth and yield of maize (Zea mays). Five treatments (0.4, 6.8 and 10 t ha-1) groundnut biomass were laid in Randomized Complete Block Design (RCBD) and...

Characterization, Taxonomic and Fertility Capability Classification of Some Soils in the Teaching and Research Farm of Taraba State University, Jalingo

, Ezeaku, P.I.^*, Kefas, P. K, Hashim, S.A.,, Ali I J, Gisilanbe S A, Kussy J J, Garpiya B. T, Yusuf B, Udoh S, Ezeaku, V. I

Result-oriented and competitive agricultural production system requires soil characterization and land evaluation. The soils of the Teaching and Research Farm of Taraba State University were characterized, taxonomically classified and evaluated for fertility capability classification. Three mapping units were delineated using a semi-detailed survey method, and profile pits were dug in the mapping ...

Local Soil Classification [Soil Association/Soil Slope–Soil Series], World Reference Base, and Usda Soil Taxonomy: Roles in Soil Survey Execution.

Okusami, Temitope A.^*

The objective was to do a comparative assessment of the best roles of three classification systems, [the “USDA-Soil Taxonomy”, the “World Reference Base (WRB)”, and the presumably Soil Association/Soil Series Concept of Nigeria] in the Soil Survey execution from Soil Mapping through to Soil Survey Report. In this instance, the concern of this paper is mostly what is best applicable when mapping le...

Effect of Nypa Fruticans and Mangrove Species on Soil Properties in Eastern Obolo, Akwa Ibom State

Ogban P. I.^*, Dickson, U. S, Ebong, U. P

The study was conducted to evaluate the effect of nypa and mangrove on soil properties to determine whether nypa in displacing mangrove was degrading or aggrading the underlying soil, in Okorombokho Community in Eastern Obolo Area of Akwa Ibom State. The study was carried out in three contiguous loca- tions, namely, mangrove (M) forest, nypa and mangrove (N&M) forest, and bare plot with neither ma...

Variability of Some Soil Properties Along a Toposequence in a Basaltic Parent Material of Vom, Plateau State Nigeria

Mahmud A. T.^*, Hassan I.M, SHEHU Bello Muhammad, Samndi M. A.

Topography influences the distribution of some soil physical and chemical properties. This study assessed some variation in soil properties resulting from the topographic effect on Basaltic parent material at Vom Jos Plateau State in the Southern Guinea zone of Nigeria. Soil samples were collected at an interval of 20m and at depths of 0 to15cm and 15 to 30cm, parcelled, labelled and taken to the ...

Characterization and Classification of Soils of a Toposequence at Osun Sacred Grove, Nigeria

Senjobi B.A.^*, Alabi K. O., AJIBOYE G. A., Adeofun C.O.

Rational use of forest resources without accurate knowledge of land and soil properties is a primary concern in achieving any millennium goal on afforestation. Hence, the morphological, physical and chemical properties of soils of a toposequence over coarse-grained granite gneiss at Osun sacred grove, in Osun State, south-Western Nigeria were studied. Three profile pits were dug under each land-us...

Characteristics of Soils Along a Toposequence in Ishiagu, Eastern Nigeria and Its Relation to Potential Agricultural Landuse.

Nsor M.E.^*, Adesemuyi E.A

The soil along a toposequence in Isiagu, Eastern Nigeria was studied to establish its influence on soil properties and its relation to potential agricultural use. In order to characterize and classify the soil, three pedons were dug along the toposequence at the crest, middle slope and valley bottom. The soils were characterized in terms of their morphological, physical and chemical properties. Th...

Effects of Phosphorus on the Phenological Traits of Maize (zea Mays) in Yola North Eastern Nigeria.

Kwaghe, E.J.^*, Gungula, D

This study was conducted during the 2000 and 2001 cropping seasons at the University Research Farm, Federal Universality of Technology, Yola to evaluate the effects of phosphorus on the phenological traits of maize (New Kaduna White) hybrid variety. There were eight treatments consisting of four levels of N, 0, 60, 120 and 180kgNha-1 and two levels of P, 0 and 60kgPha-1, replicated three times. Th...

Land Suitability Evaluation and Management of Ultisols for Some Tree Crops Cultivation in South South Nigeria

Okunsebor F. E^*, Umweni A. S.

A rigid grid soil survey was done on 115.5 hectares of land in Ultisols of South Southern Nigeria at a detailed scale to evaluate its suitability for the cultivation of some tree crops (Cocoa, Plantain, Cashew, Pawpaw and citrus). Mapping units were delineated on the basis of morphological characteristics examined at 100 m along traverses which were cut at intervals of 100 m from a predetermined b...
