Biofortification of Agricultural Effluents on Translocation and Accumulation of Micronutrients Content in Cucumber (cucumis Sativus) Plants Grown in a Coastal Plain Sand Soil South - South Ecological Zone, Nigeria

Ernest U. Eteng*

The study was conducted to evaluate the effects of agricultural effluents on Cu, Fe, Mn and Zn, partitioned in cucumber plants. Eight treatments, cassava mill effluent (CME), palm oil mill effluent (POME), poultry waste effluent PWE and their combinations were biofortified on cucumber plants. Samples were collected from the amended soils and plant parts (roots, shoots and fruits) and analyzed for ...

Combined Effect of Poultry Manure and Npk Fertilizer on Soil Plant Nutrient Composition and Growth of Rubber

Odeyemi R.T.*, Awodun M.A., OJENIYI STEPHEN OLUSOLA

Because of cost and scarcity associated with the use of chemical fertilizers on rubber and the acidic nature of rubber growing soils in Nigeria, a study was conducted into the effect of poultry manure (PM) and its combination with NPK fertilizer (NPKF) on soil and plant nutrients and growth of rubber seedlings. Six treatments replicated three times on rubber seedlings were the control, NPK fertili...

Effect of Cocoa Pod Husk Based Compost on the Growth, Nutrient Uptake and Dry Matter Yield of Roselle

Kayode C.O.*, Akande M. O., Adeoye G. O, Adekunle A. F., Ogunleti D. A.

A pot experiment was conducted at the Screen house of Federal College of Agriculture, Ibadan to investigate the effect of composts on the growth, nutrient uptake and dry matter yield of Roselle. Three types of compost were produced from cocoa pod husk (CPH), neem leaf (NL) and poultry manure (PM) namely CPH + NL + PM, CPH + NL and CPH + PM. There were fourteen treatments with three replications. T...

Suitability Evaluation of Soils of the Coastal Plain Sands for Rain - Fed Maize Production in Acid Sands of South - Eastern Nigeria.

AHUKAEMERE C.M.*, Onweremadu E. U, Akamigbo, F.O.R., Ndukwu, B.

Soils developed on Coastal plain sands have been classified as acidic soils of low CEC and soil fertility. These fragile sandy soils were evaluated for effective and sustainable rain-fed maize production using FAO land suitability classification system. Profile pits were consequently dug in four different soil units – 100m apart: Umuagwo soil unit 1, 2, 3 and 4 respectively. Results indicated that...

Soil Organic Matter and Its Active Pools as Affected by Legume/cereal Cropping Systems Under Some Agronomic Practices in the Derived Savannah Zone of Nigeria

Uzoh I .N*, Ezepue, G.U.C

Introduction of grain legumes facilitates farmers’ acceptance in adopting legume cropping system. This study evaluated effect of four cropping systems on soil organic carbon (SOC), total vesicular arbuscular mycorrhiza (VAM) spore count, soil microbial biomass carbon (SMBC), soil microbial biomass nitrogen (SMBN) and soil microbial biomass phosphorus (SMBP) within two locations (Nsukka and Moniya)...

Testing the Goodness of Fit of Infiltration Models for Soils Formed on Coastal Plain Sands in Akwa Ibom State, Southeastern Nigeria

Ogban P. I.*, Jude Obi, Anwanane, N. B., Edet, R. U., Okon, N. E.

Infiltration of water into the soil is an important physical process affecting the fate of water under field conditions, especially, the amount of subsurface recharge and surface runoff and hence, the hazard of soil erosion. The study was conducted to investigate the capability of six infiltration models, namely, Kostiakov, modified Kostiakov (A) and (B), Philip, modified Philip (A) and (B) to des...

Soil Fertility Management among Cucumber (Cucumis Sativus L.) Farmers in Ibadan, South-West Nigeria

Utibeabasi Brownson*, OLOGUNDUDU, O. M., OMONIYI J, AdeOluwa O. O

Poor soil fertility reduces the yield, market value, and sustainable production of cucumber. This study examined soil fertility practices among cucumber farmers in Ibadan. A purposive sampling method was used to select 10% of cucumber farmers from six blocks, namely Akinyele, Lagelu, Egbeda, OnaAra, Oluyole, and Iddo in Ibadan-Ibarapa agricultural zone, Oyo State. A structured questionnaire was ad...
