No full textThe field experiment was carried out at the Teaching and Research farm of Akwa Ibom State University Obio Akpa campus, in 201 B to determine the Optimum Poultry manure rate for Amaranthus. The experiment was laid out in a randomized complete block design replicated three times. The treatments were four rates of poultry manure and 6 t/ha) Growth and yield parameters were assessed, and data collected were subjected to analysis of variance (ANOVA). Significance difference at 5% probability. Results showed that poultry manure rate had significant (pe 0.05) effects on all the growth and yield parameters assessed except stem girth. The treatment that received 6 t/ ha performed best in all the parameters, while the least was recorded from the control treatment. The application of 6 t/ ha poultry manure, produced 12:19 t/ha fresh foliage yield, followed by the plot that received 4 t/ha poultry (1 1.33 t/ha), The treatment of 2 t/ha produced 7.70 t/ha foliage yield. The lowest foliage yield of 3.18 t/ha was harvested from the control plot the application of poultry manure also enhanced dry matter accumulation. The plot of 6 t/ha poultry manure produced 30.71g matter, while the control treatment had 33.14g. Therefore, the study recommended the application of 4t/ha poultry manure for optimum fresh foliage yield and dry matter accumulation

Effects of Land-use Systems and Depths on Organic Carbon Storage and Texture-related Properties of Soil at Umuahia, Nigeria
No full textSoil condition as influenced by land use systems and depths is relevant in the efforts to optimize crop production. This research examines the effect of land-use systems and depths on organic carbon storage and texture-related properties of soil. It was a 2-factor factorial experiment laid out in randomized complete block design (RCBD). The factors were land-use systems at four levels [arable farm land (AFL), 3 – years fallowed grassland (FGL), forest land (FL) and oil palm plantation (OP)] and depths at five levels (0 – 20, 20 – 40, 40 – 60, 60 – 80 and 80 – 100 cm). Twenty (4X5) treatments combinations were obtained and replicated nine (9) times. Soils were collected in a simple random sampling technic, and were prepared and analysed in the laboratory. Data generated was subjected to analysis of variance using GenStat software package version 14. The results showed that the lowest bulk density (BD) in range of 1.26 – 1.60 mg/kg were obtained under OP at 0 – 100 cm. The most rapid hydraulic conductivity (Ksat) in range of 3.62 – 1.90 cm/hr was obtained under AFL at 0 – 60 cm. The oil palm plantation had the highest range of organic carbon (OC) storage of 51.92 – 30.81 ton/ha at 0 – 40 cm, while at 40 – 100 cm, FL had the highest range of OC storage of 22.33 – 13.42 ton/ha. The undisturbed soils had higher OC storage and reduced BD at the various depths. Minimum tillage, cover cropping and shifting cultivation should be encouraged to enhance soil conditions for increased productivity
Comparative Assessment of Soil and Selected Crop in Cement Dust Contaminated Environment in Okpella Area of Edo North, Nigeria
No full textThe research was designed to compare the degree of contamination of soil and selected crops by cement dust generated during cement industry activities. Two types of soils were investigated. Soil obtained near the cement industry (OS1) and the soil obtained in a location far from the site of the cement industry (AS2). Only cassava was studied but collected at two different locations. Crop sample collected near the cement industry (OC1) and the one collected at a site far from the cement industry (AC2). The physicochemical properties of the soil samples were determined by analyzing for their percentage nitrogen (N), organic matter (OM), phosphorous (P), potassium (K), electrical conductivity (EC), moisture content (MC), bulk density (BD) and hydrogen ion potential (pH). The proximate composition of the crop samples was determined by analyzing for moisture content, crude protein, ash content, ether extract, crude fibre, dry matter, and carbohydrate. The method used was in accordance with the Association of Official Analytical Chemists’. The samples were characterized for the presence of functional groups using Fourier Transform Infrared (FT-IR) spectroscopy. X-ray Diffractometer (XRD) was used to determine the mineral composition and the heavy metals were determined using the Atomic Absorption Spectroscopy (AAS) method of analysis. The result showed that the percentage of P (28.6±0.01) and K in AS2 was higher than in OS1 (21.6±0.07). The OM in AS2 (2.34±0.01) was higher than in OS1 (2.17±0.01). The values obtained for EC were OS1 (145.7±0.01) and AS2 (115.4±0.28). The concentration of the selected elements did not exceed the maximum allowable amount. Fe has the highest concentration in soil and crop samples. The obtained value for ash content in OC1 was 4.62±0.00 and AC2 was 2.39±0.01. Carbohydrate has 74.4±0.01 in OC1 and 83.4±0.05 in AC2, however moisture content in OC1 was 7.17±0.03 and 6.86±0.03 in AC2. The results also showed the presence of various functional groups and revealed the types of minerals in the samples
