Effects of Organo-Mineral Fertilizer and Cocoa Pod Husk Ash on the Soil, Leaf Chemical Composition and Growth of Coffee

Adejobi K.B*, Famaye, A. O., Oloyede A.A., Oyedokun A.V, Adeosun S.A, Adeniyi D.O.

A nursery experiment was carried out in Ibadan (rain forest zone), Southwest Nigeria to study relative effect(s) of combined use of organo-mineral fertilizer (OMF) and cocoa pod husk ash (CPHA) on soil chemical properties, nutrient status and growth of coffee seedlings (Coffea arabica L.). Eight treatments: 5t/ha CPHA, 20 t /ha OMF, 20 t/ha OMF + 5t/ha CPHA, 15 t/ha OMF + 5 t/ha CPHA, 10t /ha OMF ...

Spatial Variability of Micronutrients in Termite Infested Soil Formed on Nupe Sandstone in the Guinea Savanna Region of Nigeria

Obi J. C.*, Ogunkunle A. O.

Soil micronutrients are nutrients required by plants in small quantity. They affect plant growth either directly or indirectly. Availability of these elements for crop growth and development may be affected by their distribution on the landscape. Variability in crop yield may indirectly be attributable to soil micronutrient variability. Termites have been implicated through their feeding habit, co...

Classification and Suitability Evaluation of the Soils of a Toposequence at Odeda, Ogun State for the Production of Rice (oryza Sativa)

AJIBOYE G. A.*, Alabi K. O., Aiboni V. U.,, Okeleye K. A, ADESODUN Johnson Kayode

A detailed survey of the soils of a toposequence at Odeda, Ogun State was conducted to characterize, classify and assess the suitability of the soils for sustainable production of rice. The rigid grid method of survey was adopted for soil mapping while the linear parametric and square root models were used for assessing the suitability of the land for rice production. The result of the study showe...
