Occurrence of multi-class pesticide residues in soils of selected farmlands and farmer’s household surroundings in the southwestern part of Oyo State, Nigeria

Shade Akinsete*, Ibiwumi K. Saliu

The indiscriminate use of pesticides for crop production in Nigeria has led to contamination of the environment. Specifically, soil contamination from pesticide residues, including banned compounds raises serious public and environmental health concerns. However, very little is known about the occurrence of pesticides in Nigerian soils. Therefore, this study investigated the occurrence and concent...

Enhancing Soil Quality and Sustainable Agriculture: A Review of Black Plum (Syzygium cumini) for Soil Amendment and Productivity

AKANBI Olorunfemi Sunday Ojo*, Isaac Kayode Oyewusi, Adegbala, A. A, Nduka B. A., Ipinmoroti, R.R.,

Jamun (Syzygium cumini), widely known as black plum, is a highly adaptable fruit-bearing tree with exceptional nutritional, medicinal, and ecological advantages. Despite its resilience in tropical and semi-arid regions, especially in areas like Northern Nigeria, its integration into formal agricultural systems remains minimal. This review synthesizes current findings on the plant’s agronomic trait...

Assessment of Soil Organic Matter Determination Techniques in Tropical Soils: Correlation Among Four Methods as Indicators of Plant Growth Potential

Toyin Blessing Odelana*, Adedoyin Adepoju, Oladele Abdulahi Oguntade, Babajide Saheed Kosemani, Adebanke Ayooluwa Olubode, Jamiu Oladipupo Azeez

Soil organic matter (SOM) is a key indicator of soil fertility, yet variability among analytical methods limits its reliable interpretation, particularly in tropical soils. This study evaluated four SOM determination methods—Walkley–Black (WB), loss on ignition (LOI), colorimetric (COL), and hydrogen peroxide (HP)—and examined their relationships with maize growth under contrasting parent material...

BIOACCUMULATION OF HEAVY METALS IN SOILS, Talinum triangulare and Celosia argentea LEAVES GROWN AROUND TEMBOGA RIVERBANK, BENIN CITY NIGERIA

EMOMU Adams*, OGBE Victor Etunim

Heavy metal levels in soils may result in heavy metal entry into the food chain, the study aimed at accessing concentration of heavy metals (Cd, Ni, Pb) in soils, Talinium triangulare and C. argentea leaf grown along Temboga Riverbank. Surface (0-15 cm) soil, T. triangulare and C. argentea leaf samples were collected randomly from Temboga Riverbank (RB), 60 meters from RB (60MRB) and 120 meters fr...

Laboratory Assessment of Basalt Dust Incubation on the Physical Properties of Contrasting Soils in Nigeria

IBRAHIM RASHEED*, Akinbile Oluwakunmi Christopher, Ewulo Babatunde Sunday, Ayodele Olumuyiwa Owolabi, Audu Luqman Muhammed

The effects of different application rates, particle sizes, and incubation periods of basalt dust on the selected physical properties of contrasting soils incubated for 90-day was evaluated in this study. A factorial arrangement with a 4×2×4 completely randomized design (CRD) with three replications was adopted. Air-dried and sieved soil samples collected from Auchi and Agbede town were treated ea...

Poultry manure rate affects growth, yield and pest infestation of Cucumber (Cucumis sativus L.)

Olubukola Odeyemi*, Makinde E A, Filani C O, Makinde A I, Akindoyin G E

Cultivation of cucumber (Cucumis sativus L.) is on the increase in Obafemi-Owode Local Government Area of Ogun State in response to increasing demands. However, nutrient deficiency and insect pests are major constraints to cultivation. This study determined the poultry manure (PM) rate required for optimum growth, fruit yield and reduced pest infestation on cucumber from field trials carried out i...

Synergistic effects of poultry manure and 2,4-epibrassinolide on soil properties and performance of groundnut in the rainforest of Nigeria

Victoria Otie*

The growth and yield response of groundnut (Arachis hypogaea L.) to fertilizer and other crop management inputs on Nigerian soils derived from coastal plain sands has been little studied. This greenhouse evaluation was aimed to determine the impact of chicken manure (CM) and 2,4-epibrassinolide (BR) on the growth and yield of groundnut. Four levels of CM: 0, 5, 10 and 15 tons/ha denoted as CM0, C...
