RESPONSE OF OKRA (Abelmoschus esculentus L.Moench) TO BIOCHAR DERIVED FROM COCOA POD HUSK AND NPK

ABSTRACTThe need to improve soil fertility and enhance crop production has led to a renewed interest in the use of cocoa pod husk (CPH) in form of biochar, an organic fertilizer, relative to, mineral fertilizer as soil amendment. The deleterious effect of inorganic fertilizer, on the environment, has been enumerated and the global effect of CPH.Field experiment on okra (Abelmoschus esculentus ) fertilized with Biochar. deri\ed from cocoa pod husks (CPH), was conducted at the Cocoa Research In...

THE INFLUENCE OF DRIP IRRIGATION FREQUENCY AND MULCHING ON THE SOIL PHYSICAL PROPERTIES AND YIELD IN OKRA. (Abelmoschus esculentus)

AbstractSeveral irrigation systems or methods have been use by many people to efficiently provide water for crop productivity. Drip irrigation system has been a best method so far, supplying water to plant, maximizing water usage, it tends to be cost effective and reduces stress. The field experiment was conducted between January 2017 and March 2017 at the Teaching and Research Farm, Federal University Oye-Ekiti (lkole Campus). The experiment design used entail; two factorial laid in a random...

EFFECT OF DIFFERENT LAND USE ON SOME SELECTED PHYSICOCHEMICAL PROPERTIES AND MICRO-AGGREGATE STABILITY INDICES IN TWO AGRO-ECOLOGICAL ZONES IN EKITI STATE, SOUTHWESTERN NIGERIA.

 ABSTRACTA study was conducted to investigate changes that may occur in the soil due to conversion of forest land to plantation, fallow and arable lands. Four locations in two-agro-ecological zones at Ikole Local Government Area, Ekiti State, were used for this study. They are; Itapaji (L 1), Asin (L2); in rainforest agro-ecological zone and Odo-Ogo (L3), Odo-Ayedun (L4) in derived savannah. Soil parameters evaluated include particle size distribution, bulk density, saturated moisture co...

GEOSPATIAL ASSESSMENTS OF HYDROLOGICAL IMPACT OF FLOOD OCCURRENCES IN ADO-EKITI AND ENVIRONS

ABSTRACTDrought is one of the a resultant effect of climate change and it is the naturally occurring phenomenon that exists when precipitation has been significantly below normal recorded levels, causing serious hydrological imbalances that adversely affect land resource production systems. Unlike many other natural hazards, drought develops slowly, making it difficult to pinpoint the onset and termination of an event.The environmental impacts of hydrological drought are Reduced stream flow a...

APPLICATION OF THE STANDARDIZED PRECIPITATION EVAPOTRANSPIRATION INDEX (SPEI) IN BENIN-OWEN A RIVER BASIN, NIGERIA

 ABSTRACTPrecipitation deficit and its daily, seasonal and annual oscillations are inherent characteristics of Nigeria's climate. Droughts are generally characterized by a prolonged and abnormal moisture deficiency. In drought studies it is important to characterize the start and end of a drought as well as its intensity, duration, frequency and magnitude. The objective of this study was to apply the Standardized Precipitation Evapotranspiration index (SPEI) for drought assessment in the...

THE EFFECT OF LAND USE ON SOIL AGGREGATE STABILITY AND SOIL CARBON SEQUESTRATION IN SOME SELECTED SOILS OF SOUTH EASTERN NIGERIA

 AbstractThe Information on the effect of different land use systems on the aggregate stability and carbon sequestration is crucial for the recommendation of efficient land management practices. This study was conducted to evaluate the variation in aggregate stability and carbon sequestration under different land use systems in two agro ecological zones of south eastern Nigeria. The agro ecological zones were derived savannah and rainforest while the land use systems studied were cu...

LNFLUENCE OF BIOCHAR ON VEGETABLE (Amaranthus viridis) UPTAKE ON CADMIUM CONTAMINATED SOIL

 ABSTRACTCadmium (Cd) is a common  environmental contaminant found in soils. Unlike other metals. Cd has no biological role, and is potentially toxic to microorganisms. The concentrations of cadmium in agricultural soils depend upon the amounts present in the parent rocks from which the soils form, the amounts added in the form of fertilizers and soil amendments, the amounts deposited onto soils from the atmosphere, and the amounts removed by harvested crops and by leaching. It...

ASSESSMENT OF POTENTIALLY TOXIC ELEMENTS IN HAND DUG WELLS AND BOREHOLE WATER IN IKOLE-EKITI AND ITS ENVIRONS, EKITI STATE, NIGERIA.

ABSTRACTWater is an important resource for almost all human activities like agriculture, industry, transportation, domestic uses and the proper functioning of the human body, The study examined the physiochemical properties and potentially toxic metals in hand-dug wells and boreholes in Ikole Ekiti and its Environs. Six functional hand-dug wells and six boreholes in the area were sampled and analyzed using standard procedures. Potential toxic metals were determined using Atomic Absorptio...

CHEMICAL COMPOSITION OF BOREHOLE WATER IN TWO LOCAL GOVERNMENT AREAS OF ONDO STATE WITH SPECIAL REFERENCE TO POTENTIAL TOXIC METALS

 ABSTRACTMany households are used to the construction of shallow wells, but the wells hardly provide adequate water supply in term of volume and quality throughout the year. As a result, government adopted the construction of boreholes as an alternative to pipe-borne water supply and as an immediate solution to water supply and quality problem. Groundwater (borehole water) samples were collected randomly from two (2) Local Government Areas: Akure south (Oda, Ijoka, Sebi, Kajola, Ija...

EFFECT OF MEXICAN SUNFLOWER (Tithonia diversifolia) MULCH ON THE GROWTH AND YIELD OF MAIZE (Zea mays L.)

 ABSTRACTGreenhouse study was conducted at Federal University Oye- Ekiti, Department of Soil Science and Land Resources Management between June and August 2016 to compare the growth and yield of maize (Zea mays L.) using different rates of organic (Tithonia diversifolia) and Inorganic fertilizer. The effect of the amendments on the soil chemical properties was also evaluated. The experiment was laid out in a Completely Randomized Design with four replications. Tithonia diversifolia was a...

RAINFALL DISTRIBUTION AND THE LENGTH OF GROWING SEASON IN NORTHERN NIGERIA

 ABSTRACTThis study examines the rainfall distribution and the length of the growing season in Northern Nigeria using the daily rainfall data from the selected stations Gasua, Kaduna, Kano, Katsina, Maiduguri, Potiskum, Sokoto, Yelwa, Zaria. The data were collected from the archives of the Nigerian Meteorological Services, Oshodi, Lagos. The length of the growing season was determined using the cumulative percentage mean rainfall method. The growing seasons in Gasau, Kaduna, Kano, Katsin...

LAND EVALUATION STUDIES OF SOME SELECTED SOILS IN IKOLE SOUTH-WESTERN NIGERIA

 ABSTRACTSustainable use of soils requires in-depth knowledge of the formation, genesis and properties of soil. It is in view of this that some soils derived from granitic parent rock in Ikole, South- western Nigeria covering 33.7 hectares of land where mapped at a scale of 1:50,000 using a combination of convectional and remote sensing methods of soil survey. The objective was to generate detailed information on the properties of the soil for their sustainable agricultural use and ...

EFFECT OF LAND USE ON SOIL CARBON SEQUESTRATION IN SOILS OF THE DESERT MARGIN IN NIGERIA

 ABSTRACTExploring the impact of changes in land use in soils of the desert margin soils in Nigeria .This research is a key component to global climate change. Soil samples were taken in two vegetation zone Sahel and Sudan Savannah under four different land uses( Forest Area, Arable land, Fallow land and Grazing land) at a depth of 0-15cm. The locations under Sahel Savannah are Goronyo ,Gamawa and Minjibir while the site under Sudan Savannah are Hadeija and Ulela. A 5x4x3 factorial exper...

METHODS OF ESTIMATION OF IONIC STRENGTH IN HAND DUG WELL WATER OF IKOLE-EKITI EKITI STATE NIGERIA

ABSTRACTThe estimation of ionic strength and its activities in well water source within the vicinity of Ikole local government Ekiti state was conducted. A total of fifteen ( 15) water samples were collected from five locations (Al, A2, A3, Bl, B2, B3, Cl, C2, C3, DI, D2, D3, El, E2 and E3) from the study area. These samples were examined for major cations and major anions using Atomic Absorption Spectro-photometer (210 / 211 YGP (AAS)) and Technicon Auto analyzer AAII system respectively. Fr...
