Soil Properties and Response of Yam to Ash Application at Akure, Nigeria

Kayode B. O.*, OJENIYI STEPHEN OLUSOLA, Odedina S. A

Two experiments were conducted at the Federal College of Agriculture Akure, Southwest Nigeria to test effectiveness of a crop waste wood ash as source of nutrients for plantain (Musa paradisica) and yam (Dioscorea rotundata). Effect of wood ash at 0, 0.4, 0.8 and 1.2 kg/plant was studied as to the effect on soil chemical properties and performance of the crops. The test soil was low in organic mat...

Suitability Evaluation of Some Plinchustalfs for Rain - Fed Rice Production in Southern Guinea Savanna of Nigeria

Adeboye M.K.A*, Lawal B.A, TSADO P. A., Ezenwa M I S, Afolabi S.G., Adekanmbi A.A.

The plinthustalfs of Minna, southern Guinea savanna zone of Nigeria, have poor physical properties which induce water-logging during wet seasons which may make them suitable for rice production. This study evaluated their suitability for rain-fed rice production using FAO Land Suitability Classification system. Two sites, the Experimental Farm of the Federal University of Technology, Minna (EF) an...

Use of Agricultural Wastes for Improving Soil Crop Nutrients and Growth of Cocoa Seedlings

Akanni D.*, Odedina S. A, OJENIYI STEPHEN OLUSOLA

The quest for organically-produced cocoa produce in the world market necessitated recent focus on research into the use of agricultural wastes as source of nutrients in cocoa (Theobroma cacao) production. This work carried out at Federal College of Agriculture, Akure is the comparative study of effect of kola testa (KT), cocoa pod ash (CPA), melon testa (MT), cowpea pod (CP), kola pod (KP) and coc...

Macro and Micro Nutrients Status of Selected Soils Based on Land Use in Southwest, Nigeria

Thomas, E.Y*, Omueti, J.A.I, Akpan, I.O

In Africa, production of food per capita had suffered a decline in the past decade despite the enormous increase in population. To sustain the growing dependence on agricultural production the use of fertilizers became paramount and more fertilizers are now applied than before. Ironically, agricultural production problem persisted. This could be attributed to improper use of fertilizers due to lac...

Investigation of Mycorrhizae Populations of Roots and Rhizosphere Soil of Plantain (musa Spp)at the Various Agro-Ecogicalzones in Cross River State

O.S. BELLO*, E.O. ATURE

The study was conducted during 2009/2010 dry season at locations (11o 58’ N, 8o 25’E and 110 39’N, 080 027’ E) both located in the Sudan Savanna Ecological Zone of Nigeria. The study was aimed at evaluating the response of cowpea varieties to sowing dates and irrigation intervals. The treatments consisted of three cowpea varieties (IT93K-452-1, Achishru and IT97K-205-8), three sowing dates (Early-...

Effect of Tillage, Poultry Manure and Npk Fertilizer on Soil Chemical Properties and Maize Yield on an Alfisol at Abeokuta, South - Western Nigeria

M.A. Busari*, F.K. Salako

Tillage is a basic soil management tool that significantly affects soil characteristics and plant development. This study examined the 2-year effects of tillage, poultry manure (PM) and NPK 20:10:10 fertilizer on soil chemical properties and maize yield. The experiment was a split-split- plot design with three replications. Tillage (zero tillage (ZT), minimum tillage (MT) and conventional tillage ...

Cowpea Yield Response to Sowing Dates and Irrigation Intervals

A. M. SAMNDI*, J. O. ICHI, S. MIKO, A. A. ADNAN

Four soil profile pits were dug under differing cropping systems at Nigerian Institute For Oil Palm Research (NIFOR) experimental plantations in Benin City and chemically analysed. Cropping systems were sole oil palm, oil palm with cassava, oil palm with plantain, and oil palm with coconut. Samples were collected at 0 – 20, 20 – 40, 40 – 60, 60 – 80 and 80 – 100cm depth and analyzed for K, P, Ca, ...

Influence of Plant and Animal Manures on Soil Chemical Properties and Tomato (lycopersicum Esculentum) Yield

Olowokere F. A.*, ADESODUN Johnson Kayode, AKINTOKUN Pius Oluwagbemiga, Egbedokun A.O., Oyenekan, O.A., Martins M.S.

Low nutrient status of tropical soils requires external source of nutrients for sustainable cropping. Field experiments were conducted in 2009 and 2010 cropping seasons at the Federal University of Agriculture, Abeokuta, Nigeria to evaluate the effect of plant and animal manures on soil chemical properties and yield of tomato. Treatments used were: poultry manure (PM), Tithonia diversifolia compos...

Slope Position and Depth Effects on Selected Soil Physical Properties Under Oil Palm (elaeis Guineensis) Plantation

O. O. Olubanjo*, F. U. Maidoh, P.O. Oviasogie

A study was conducted to examine the influence of slope position and depth on soil physical properties in an oil palm (Elaeis guineensis) plantation established on a gently sloping terrain in NIFOR Benin, Nigeria. A line transect was delineated along the slope of the selected plantation. The line transect was 45 m long and 45 m wide. It was divided into three equal slope segments namely, Summit, M...
