ABSTRACT Field experiment was conducted to evaluate the combined effects of drip irrigation frequency and different mulching materials on the growth and yield of okra (Abelmoschus esculentus L, Moench). The field experiment was 3 x 3 factorial using Randomized Complete Block Design. The factors were three irrigation intervals (daily, twice and thrice weekly) and three mulches (plastic, grasses and no mulch) and replicated four times. It was observed from the result that okra responded signifi...
ABSTRACT Management practices to adopt in improving the land productivity has always been a challenge. The arable land used for farm practical year students and the fadama used for raising vegetable.s and maize during the dry season are spoken about as not very productive. This is due to the gross lack of information on both the physical and chemical properties of the soils under the different land use types in the Federal University Oye-Ekiti. These land use types continued for over three ...
ABSTRACT This research was conducted in Ikole-Ekiti to evaluate the effects of four land use types (forest plantation, arable land, fallow land and ranchland) and soil depth on soil organic carbon fractions namely; particulate organic carbon (POC), soil microbial biomass carbon (SMBC), total organic carbon (TOC) and water soluble organic carbon (WSOC). Soil samples were taken at 0-5, 5-10, I0-20 and 20-30 cm and 0-30 cm depths at each site using soil auger. The soil samples were analyzed fo...
ABSTRACT Forest soils in Ekiti state western Nigeria are destroyed due to agricultural activities. Information about the effect of land use on soil is important for soil sustainability and productivity. A study was conducted to investigate changes that may occur in the soil organic carbon content (SOC) and some selected soil physical properties due to conversion of forest to arable land. Six locations that were selected for this purpose include; Ona-Ara (Ll), Asin (L2), Ijesa Isu (L3), Odo-...
Abstract Anthropogenic activities can destroy or drastically reduce the organic carbon contents of soils. This study was conducted to evaluate the effects of two land use management practices (arable land and oil palm land), soil depth and topography on soil organic carbon contents. The study was carried out in Ikole-Ekiti, Ekiti State, Nigeria. At each location, three topographic units were identified as upper slope, middle slope and lower slope at 50 m apart. A mini pit of 150 cm by 100 cm ...
Abstract. Pepper (Capsicum spp.) production by farmers in southwestern Nigeria is limited by low yield due to poor genetic potentials of most cultivars available, use of poor quality seeds, disease infestation, and poor managment practices among others. To overcome the constraints, some varieties of pepper developed at Embrapa Brazil and NIHORT Nigeria, were introducedfollowed bytraining of 100 small scale farmers . Participatory field demonstrations of the improved varieties of pepper were c...
ABSTRACT The relative contributions of clay and organic matter to the cation exchange capacity of soils have been of great interest to many researchers. Organic matter. as a critical component of the soil. plays. significant roles which far exceed its quantitative distribution in the soil. It is regarded as the major contributor of CEC in weathered soils because of its several functional groups such as R-COO-. R-C=O. R-COH and R-SI I that deprotonate and leave net negative charges on the...
Background and Objective: Aquic Arenic Paleudults soils are developed at valley bottom of a basement complex parent material of the sub-humid tropical rainforest. The aim of the study was to determine the mineralogy of clay components of Aquic Arenic Paleudults soils of Akpamkpa, Southeastern Nigeria. Materials and Methods: The study mineralogy of clay components of Aquic Arenic Paleudults soils of Akamkpa, southeastern Nigeria was carried out on 50 hectare land. Two soils were collected fro...
In precision Agriculture, geostatistical methods as a predictive tool have been extensively utilized. The approach estimates soil properties spatial variability and dependency. This study was carried out in Ovia north east Local Government Area of Edo State of Nigeria in order to map soil properties (Sand, Clay, pH, OC, P, N and CEC) and predict their spatial variability. Twenty-nine (29) soil samples were collected randomly from Typic Kandiudults soil type under three different land use, tea...
Abstract-The study was carried out to investigate the effect of phosphate fertilizer application on manganese (Mn) adsorption. Composite sandy loam and loam soil samples (0-20 cm) were collected from Dalori and Gongulong and analysed for their texture and chemical properties. Mn adsorption experiment was carried out. Loamy soil collected at Gongulong was moderately acidic in reaction, moderate in e...
The research was carried out to study the distribution of some macro nutrients and chemical Properties in some semi–arid soils of Borno state. Three composite soil samples were collected at different locations at depth of 0-20 cm which were analysed for some macro nutrients and chemical properties. University of Maiduguri (Unimaid) soil is slightly acidic to neutral in reaction, �...
ABSTRACT The study was carried out in Dekina Local Government Area of Kogi State to determine the soil quality indicators. Among the towns which the research was carried out are ABOCHO, EGUME, AND OJIKPADALA. The area is characterized by sandy layer, sand content ranged between 78.6% and 84.6%, silt ranged between 1.72% and 4.72% and clay ranged from 13.68% to 17.68%.The pH of the soil was found to be acidic and ranged between 4.8 and 6.9.The soil organic carbon ranged between 0.57% and 1.04%...
ABSTRACT A laboratory experiment was set up at Kogi State University Anyigba at the faculty of Agriculture, department of soil and environmental management Laboratory to evaluate the effect of different levels of poultry manure on total heterotrophic bacteria in a cropped soil. Soil samples were collected from many random points at the Kogi State University Teaching and Research Farm at a depth of 0-15cm using an auger. The collected samples were bulked into one composite sample which was tak...
This study evaluates the fertility of small scale farmers’ field in Ijumu Area of Kogi State. The area lies within the Southern Guinea Savannah zone of Nigeria. The study area is having three districts; Ijumu Oke, Ijumu Arin and Gbedde. 60 farmers were identified through the Agricultural Development Agency and questionnaires were administered to them to identify soil management practices and problems among the farmers. Soil samples were collected from three farmers’ field, one farme...
