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...

Sole and combined effects of Mexican sunflower, cabbage residue, and poultry manure on soil chemical properties, growth, and yield of golden melon (Cucumis melo L.) in a derived savanna ecology of Nigeria

Adekiya, A.O*, Aboyeji, C. M, Gbadamosi, A.

Hitherto, the knowledge about the effect of mexican sunflower, cabbage residue, and poultry manure residues in the soil chemical conditions is still limited. Hence, a field experiment was carried out in 2020 to assess the effects of sole and combined applications of mexican sunflower (Tithonia diversifolia) leaves, cabbage (Brassica oleracea) residue and poultry manure on soil chemical properties ...

Effects of Land Use on Forms of Phosphorus in Coastal Plain Sands of Nigeria

Jude Obi*, Ibia, T. O, Ikott, I. E.

This research studied the effect of land uses changes on the forms of phosphorus within the coastal plain sands landscape of southeastern Nigeria. Satellite imageries and soil data including phosphorus fractions were used for the study. Spatial coverage of forest and agricultural (fallow and farmland) land uses, accompanying soil properties and forms of phosphorus were estimated. There was progres...

Tillage and Residual Effect of Some Organic Amendments on Aggregate Associated Soil Carbon of an Ultisol, Growth and Yield of Maize and Cowpea Intercrop

Onunwa A.O.*, Igwe, C.A, Mbonu O. A

associated soil carbon (C WSA) and yield of maize and cowpea intercrop in an Ultisol, Southeastern Nigeria. A land area of 0.1125 ha was planted to sole cowpea, sole maize and maize-cowpea intercrop using minimum tillage (NT) and conventional tillage (CT) with poultry droppings (PD), pig waste (PW), and Cassava peels (CP) as amendments at the rates of 20, 90, 100 t/ha respectively and a control. T...

Phosphorus Status in Some Soils of Mid - Western Agro - Ecological Zone of Nigeria

Orhue E. R.*, John Kingsley

The trial was carried out to determine the status of various forms of P in soils formed on 3 types of parent materials in Southern Nigeria. Soil samples were obtained from3 ha area in each of the locations at 0-15 cm and 15-30 cm depth and then subjected to routine physical and chemical analysis. Results revealed that the sand component of the soils which ranged from 771 gkg-1 to 892 gkg-1 decreas...

Physical and Chemical Characterization of Some Selected Soils in University of Maiduguri, Borno State Nigeria

Ibrahim Babagana Buji*, Ibrahim Adamu, Magaji M. J, Hayatu N. G, Zubairu A M, Hannatu J., Murtala Bawa Sharu

A semi-detailed survey was conducted to characterize some physical and chemi- cal properties of soils of Teaching and Research Farm University of Maiduguri, Borno State. Three sites were selected on the basis of land forms and surface tex- ture and their description were taken using two soil profile pits at each sites. The soils collected were subjected to laboratory analysis using standard proced...

Soil Mapping, Classification and Morphological Characteristics of the University of Benin Land

Okunsebor F. E*, Umweni A. S.

This study was conducted to map, and classify the soils of University of Benin Teaching, Research and Integrated Farm site. Rigid grid soil survey method at an intensive scale was done on a 62-hectare land that produced seven mapping units. In each mapping unit, a representative pedon was sunk, described and sampled. Soil samples were analyzed using standard methods. Data generated were ana- lyzed...

Classification of the Obudu Plateau (crest) and Sub Plateau Soils of Cross River State, Nigeria.

ESSOKA A. N.*, ESSOKA P. A

The soils at the plateau (crest) and sub plateau of three ranges of Obudu mountains were studied using profiles. Two profiles each were dug at the Ranch, Belinge and Belegate. These six profiles were studied morphologically and physicochemically; and the result used for (USDA and FAO) classification. The plateau and sub plateau soils of the Ranch and Belinge possessed mollic A epipedons and argill...
