oil Microbial Activity Under Complementary Applications of Organic and Inorganic Amendments

Sangotoye S. E.*, Atere C. T., Taiwo, L. B, Olayinka A.

The research described and quantified soil consistency as cumulative consistency value (CCV) at two moisture levels for different horizons of soil profiles located on sedimentary and basement complex parent materials. It was found that the CCVs of soils formed on sedimentary deposits were between 18 and 28 while the CCVs for the soils formed on the...

Enhancing Maize (zea Mays L.) Growth and Nutrient Uptake Via Application of Water Hyacinth (eichornia Crassipes [mart.] Solms) Compost and Inorganic Nutrients

Atere, C.T*, Olayinka A.

A soil culture experiment was conducted in the screenhouse to assess the growth response of maize to water hyacinth compost application rates and their residual effects. Water hyacinth (Eichhornia crassipes [Mart.] Solms) compost, namely, 2.5 t ha-1(W1) and 5.0 t ha-1 (W2) with and without fortification with fertilizer, F [N (25 kg ha-1 as urea) an...

Soybean Nodulation and N2 - Fixation as Influenced by Cow Dung, Wood Ash and Rhizobial Inoculation in Tropical Acid Soils (typic Dystrudept )

Soretire A. A*, Olayinka A.

The effects of cow dung and wood ash applications with and without rhizobial inoculation on modulation, and N2-fixation by soybean (Glycine max (L.) Merrill) were investigated in tropical acid dystrudepts under greenhouse and field conditions. The field experiments were located at Epe and Ijebu-waterside (Ibiade) of Lagos and Ogun States, southwest...

Effects of Poultry Manure and Portland Cement Additions on Soil Physical Properties and Microbial Activities

Ogunrewo O. M.*, Olayinka A.

The topsoil sample (0-15 cm) of the Apomu series (Inceptisol) was amended with three rates each of poultry manure and cement (0, 5.0, 10.0 g / kg) in a 3 x 3 factorial combination. The experiment was carried out in the laboratory at room temperature. The poultry manure and cement were thoroughly mixed by hand with 100 g portions of air-dried, sieve...

Response of Soybean (glycine Max L. ) to Cow Dung and Wood Ash Application in Tropical Acid Soils of South - Western Nigeria

Soretire A. A.*, Olayinka A.

The study examined the effect of cow dung (beef cattle manure) and wood ash on the growth and yield of soybean in two acid soils (Typic dystrudepts) of south-western Nigeria. The experiment was conducted under field conditions at two different locations, namely, Epe and Ibiade (Ijebu- waterside) of Lagos and Ogun States, Nigeria, respectively. It w...

Soil Chemical Properties and Growth of Maize (zea Mays L.) as Affected by Cocoa Pod Compost Based N and P Fertilizer

Atere C. T.*, Olayinka A.

A greenhouse soil culture experiment was carried out to investigate the effects of organo-mineral fertilizers on soil chemical properties, growth, dry matter yield and tissue nutrient contents of maize (Zea mays L.). The organo-mineral fertilizers consisted of cocoa (Theobroma cacao) pod compost fortified with inorganic N and P. Five (5) kilogramme...
