Microplastic Contamination Alters Soil Hydraulic Properties and Inhibits Maize Growth: A Factorial Assessment Across Contrasting Soil Textures.

EJI EJOR TANGBAN^*, OGUIKE, P. C., Godwin Nnaji, BENJAMIN, J. I.

Microplastic pollution in agricultural soils constitutes an emerging threat to food security, yet the interactive influence of soil texture and contamination intensity on crop productivity remains inadequately characterized. A 3 × 4 factorial pot experiment was conducted under controlled conditions at Bendeghe Ekiem, Cross River State, Nigeria, to evaluate the combined effects of high-density poly...

Heavy Metals Accumulation in Soil and Amaranthus Cruentus L Irrigated with Dye Effluent Polluted Stream Water in Abeokuta, Southwest Nigeria

Oguntade O. A.^*, Adetunji M. T, F. K. Salako, T. A. Arowolo, Jamiu Oladipupo Azeez

This study evaluated the quality of Amaranthus cruentus irrigated with dye effluent polluted stream and water from a deep hand-dug surface well (well-water). It also assessed the levels of heavy metals including Manganese, Iron, Copper, Zinc and Chromium in soil and amaranths irrigated with the waters in two dry seasons. The results showed that the pH (9.67) and NO3- (226.76 mg L-1) contents of th...

Effect of Nitrogen and Micronutrients on Grain Yield of Maize Varieties in the Northern Guinea Savanna Alfisol.

B. T. Olowookere^*, Uyovbisere E, OJENIYI STEPHEN OLUSOLA

Field experiments were conducted in 2008 and 2009 in the Guinea Savanna ecology of Nigeria to investigate the effects of nitrogen fertilizer and micronutrients on the grain yield of two quality maize and two normal maize varieties. The treatments were four rates of inorganic fertilizer N (0, 50, 100, 150 kg Nha-1) and two rates of cocktail micronutrient mixtures. These were tested in a Randomized ...

Soil Physical and Chemical Spatial Patterns under Land Use Intensification in a Nigerian Protected Area

Adesina Abudlkabir Wahab^*, Kabir Kayode Adebayo, Toyeeb Abayomi Abioye, Yusuf Folorunso Abdulkareem

Population growth, food demand, and low farm income drive landuse intensification and encroachment into protected areas. Landuse intensification within protected landscapes alters soil physical and chemical properties with implications for ecosystem stability. This study quantified soil variability across four land-use types (LUTs): long-term reserved forest (>10 years; RAG), recently reclaimed re...

Nutrients Concentration and Root Count of Cassava as Influenced by Residue and Npk Fertilizer

Babadele D.O.^*, OJENIYI STEPHEN OLUSOLA

Experiment was conducted at two sites Ayegunle and Oka in South-West Nigeria to study effect of combined plant residues sawdust ash (SDA) and siam weed (Chromolaena odorata) (CR) and NPK (15:15:15) fertilizer on leaf N, P, K, Ca and Mg of Cassava. The parameters were evaluated at 3,6,9 and 12 months after planting (MAP) for nutrient concentrations and root count of cassava. The test soils are sand...

The Effects of Different Types of Fertilizers on the Growth and Yield of Sesame (sesamum Indicum L) In Makurdi

OJENIYI STEPHEN OLUSOLA^*, Ibrahim, N. B., Iorlamen, T.

A field experiment was conducted at the Teaching and Research Farm of the University of Agriculture, Makurdi, Benue State, Nigeria during the 2012 cropping season to determine the effects of different fertilizer types on growth and yield of Sesame. The experiment was laid out in a Randomized Complete Block Design and replicated three times. There were six treatments which included NPK – 15-15-15, ...

Influence of Agro - Wastes on Soil Properties, Growth and Yield of Maize (zea Mays L.) in an Acid Ultisol of Owerri, Imo State

Onwudike S U^*, Asawalam Damian Okwudiri, Ano, A. O.

We investigated the effect of selected agro-wastes on soil properties, growth and yield of maize (Zea mays) in a Typic Haplusult during 2011 and 2013 planting season at the Teaching and Research Farm of Federal University of Technology, Owerri Imo State Southeastern Nigeria (Latitudes 5° 21’ N and 5° 27’ N and Longitudes 7° 02’E and 7° 15’ E). The experiment was a 3 x 4 factorial fitted in a Rando...

Soil Properties and Cocoa (theobroma Cacao L.) Nutrient Uptake as Affected by Organic and Inorganic Based Fertilizers in Southwestern Nigeria

Adejobi K.B^*, Agele S.O., Ewulo Babatunde Sunday

Low soil fertility is a major problem for cocoa establishment on the field, however, cocoa (Theobroma cacao L) is characterized by high nutrient demand particularly N, P, K, Ca and Mg during its early growth. In this study, the effects of organic and inorganic fertilizers on soil properties and nutrient uptake of cocoa in Ibadan and Owena soils of Southwestern Nigeria were investigated in 2011. Th...
