Seasonal and Fertiliser Effect on the Yield of Bell Pepper (capsicum Annuum L.) in Ibadan, South Western Nigeria

Olufunmi O. O.*, Adeoye G. O

Emerging supply crisis in the food chain of crops such as Bell pepper (Capsicum annuum L.) from traditionally major producing areas of Southern and Northern guinea savannah of Nigeria to other parts of the country makes it expedient to cultivate the crop under different weather conditions and fertiliser requirements. Field trials were conducted in Ibadan, South western Nigeria (derived savannah ag...

Evaluation of Npk Fertilizer Formulations on the Growth and Dry Matter Yield of Coffee Seedlings

Ibiremo, O.S.,*, Akanbi O. S.O., Oloyede A.A., Adebowale L.A

A greenhouse study was carried out at Cocoa Research Institute of Nigeria, Ibadan to evaluate the effect of NPK fertilizer formulations on the growth and dry matter yield of coffee seedlings. The treatments consisted of NUTRICO-1 (NPK-liquid fertilizer) applied at rate 5 and 10 ml/15L water) and NPK- solid fertilizer 15:15:15 applied at 1, 3 and 5g/coffee seedling and a control. Data on growth of ...

Micronutrient Status of Grain Size Fractions in Soils of Land Uses in Mbano, Southeastern, Nigeria

Bethel Ugochukwu Uzoho*, Irokwe I. F.

Micronutrient status in grain size fractions provides information on the active soil fraction and the ability for stabilization against microbial decomposition. Total, available, exchangeable and water-soluble Fe, Zn,Cu and Mn in bulk and grain size soil fractions were evaluated in three landuse types (Cassava, Cashew and Oil palm) in Ehime Mbano, Southeastern, Nigeria. Also, selected soil propert...

Characterization, Land Capability and Fertility Classification of Soils Along Kpantinapu - Nukkai Toposequence in Jalingo, Taraba State

Gisilanbe S A*, Hashim, S.A.,, Garpiya B. T, Kussiy J. J, Ibrahim I. S

The objective of this study was to characterize the soils of the study area, deter- mine some soil properties and classify the soils according to USDA Taxonomic System. Coordinates of the Pedons were obtained using hand held Geographic Positioning System (GIS) and one (1) profile pit was dug at the upper, middle and lower slope respectively. Some soil physical and chemical properties were deter- m...

Effect of Integrated Application of Soil Amendments on Nutrient Uptake and Soil Properties in a Tropical Alfisol

Amusan O. A.*, OJENIYI STEPHEN OLUSOLA

A field experiment was conducted on a tropical alfisol for two consecutive years to determine the effect of integrated application of nutrient sources on nutrient uptake and soil properties. The treatments consisted of two rates of poultry manure (0 and 5 t ha-1 ), three rates of N fertilizer (0, 50 and 100 kg N ha-1 applied as urea), three rates of P fertilizer (0, 30 and 60 kg P ha-1 applied as ...

Soil Suitability Evaluation for Maize in Lere Local Government Area of Kaduna State Nigeria

Magaji M. J*, Samndi M. A., Ado A A, Buji I. B., Abubakar M. A.

The soils of Lere (Saminaka) in Kaduna state, Northern Guinea Savanna climatic zone were evaluated for suitability of maize (Zea mays) cultivation, employing various methods. Data were obtained through field study and laboratory analyses. Three soil Units were delineated, and one profile was sunk in each of the soil units. The profiles were described according to the USDA soil survey manual, and s...

Parametric and Non - Parametric Suitability Evaluations of Rice Soils of Asu River Group Parent Materials in Ohaozara, Nigeria

Obasi S. N.*, Obasi C. C., Okorie A. P

The study was carried out in Ohaozara Southern Ebonyi State in Southeastern Nigeria. Study area was identified in a rice soil of about 120 hectares used for FGN/IFAD Value Chain Development program (VCDP). Three profile pits were dug on a transect line of about 100 – 200m apart for suitability evaluation study. The aim of the study was to use parametric and non – parametric suitability evaluation ...

Soil Vulnerability and Degradation Assessment of Mountainous Area in Ekoli - Edda, South - East Nigeria

Ekpe, I I*, Oludare C. G,, Oti, N.N, Ishiusah O. W,, Egboka, N.T, Orji A., Nwankwo V.C.

Soil vulnerability and degradation assessment of the mountainous area in Ekoli-Edda, South-East Nigeria was carried out on four experimental sites namely Egu, Ugwuelu 1, Ugwuelu 2, and Ocha. The slope of each study site was divided into three namely summit, mid-slope, and foot slope, and slope attributes were measured. Two profile pits were sunk equidistance apart at each of the slope positions an...

Influence of Forms of Iron and Manganese Oxides on the Physical and Chemical Properties of Soils Formed Over Mica - Schist in a Northern Guinea Savanna, Nigeria

Kefas, P. K*, Abdulrashid Shobayo Babatunde, Ofem, K.I, Akwoga, J.A, Asadu Charles Livinus, , Ezeaku, P.I.

Three forms of oxides of iron and manganese were evaluated on soils developed in mica-schist lithology within the basement complex formation of Taraba State, North-eastern Nigeria. The results from the three oxide forms namely, pyrophos- phate extractable (Mnp/Fep), oxalate extractable (Mnox/Feox) and citrate- bicarbonate-dithionite extractable (Mnd/Fed) examined were subjected to both descriptive...

Genotypic Effect of Groundnut on Nodulation, N Fixation and N Balance in the Two Savannahs of Nigeria

Moji K.T*, Jibrin M. J., Umar F. G., Abubakar U. D

Identification of high N-fixing groundnut genotypes and integrating them into the prevailing cereal-based cropping systems can reduce the need for nitrogen (N) fertilizers, thus minimizing their high cost and associated environmental consequences. This study was conducted to estimate the amount of symbiotically fixed N by groundnut genotypes and its contribution to soil N and yield of groundnut. T...
