In the present investigation, soils fallowed to Mexican sunflower (Tithonia diversifolia), siam weed (Chromolaena odorata), spear grass (Imperata cylindrica) and soil cropped to cassava were chemically analysed. Soil physical properties such as bulk density, total porosity and moisture content were also determined. The soils were also used to grow maize in screen house. Soils fallowed to Tithonia and Chromolaena had higher mineral values like nitrogen, phosphorus, potassium, calcium, magnesium and also organic matter. The plant morphological paramters like maize height, girth and leaf area were also found higher than cropped land and soil fallowed to spear grass. Soils under Tithonia and Chromolaena had more favorable physical properties compared with soils under cassava and spear grass as indicated by lower bulk density and higher total porosity. This can be adduced to the ability of the Tithonia and Chromolaena weeds to protect the soil, proliferate surface soil with their roots, and attract fungi, increase biomass and organic matter.

This paper examines the likely perceived causes of climate change, adaptation strategies employed and technical inefficiency of arable crop farmers in Ondo State, Nigeria. Data were obtained from primary sources using a set of structured questionnaire assisted with interview schedule. Multistage sampling technique was used. Data were analyzed using the following: descriptive statistics and the stochastic frontier production function. The findings showed that majority of the respondents (59.1 %) still believed that climate change is a natural phenomenon that is beyond man’s power to abate while industrial release, improper sewage disposal, fossil fuel use, deforestation and bush burning were perceived as the most human factors that influence climate change by the category that chose human activities (40.9 %) as the main causes of climate change. The main employed adaptation strategies by the farmers were mixed cropping, planting early matured crop, planting of resistant crops and use of agrochemicals. The arable crop farmers were relatively technically efficient with about 53 % of them having technical efficiency above the average of 0.784 for the study area. The study observed that education, adaptation, perception, climate information and farming experience were statistically significant in decreasing inefficiency of arable crop production. Therefore, advocacy on climate change and its adaptation strategies should be intensified in the study area. © 2016 Springer-Verlag Wien Source

The data on poultry manure (PM), wood ash (WA) and NPK fertilizer are needed to identify strategies for sustainable management of a degraded Alfisol for improving agronomic productivity. Hence field experiments were conducted at Owo in the forest-savanna transition zone of southwest Nigeria to study the effects of organic amendments and NPK fertilizer on the soil chemical properties, leaf nutrient concentrations, growth and pod yield of okra. Seven treatments considered in 2006, 2007 and 2008 were control (no manure/fertilizer), 5.0 t ha-1 PM, 10.0 t ha-1 PM, 5.0 t hav WA, 10.0 t ha-1 WA, 5.0 t ha-1 PM + 5. 0 t ha-1 WA and NPK 15-15-15 (200 kg ha-1) fertilizer. The treatments were laid out in a randomized complete block design with three replications. Organic amendments (PM and WA) improved soil organic C, N, P, K, Ca and Mg and leaf N, P, K, Ca and Mg concentrations, growth and yield of okra compared with the control. NPK 15-15-15 fertilizer increased soil N, P and K, but did not increase soil organic C, Ca and Mg and leaf Ca and Mg of okra. Combined application of 5.0 t ha-1 PM + 5.0 t ha-1 WA mostly improved leaf and soil N, P, K, Ca and Mg and soil organic C, growth and okra yield compared with other treatments. The superior performance of 5.0 t ha-1 PM + 5.0 t ha-1 WA was adduced to increased availability of nutrients following the inclusion of PM which aided faster decomposition and release of nutrients. Relative to the control, using the mean of the 3 years, 5.0 t ha-1 WA, 5.0 t ha-1 PM, NPK fertilizer, 5.0 t ha-1 PM + 5.0 t ha-1 WA, 10.0 t ha-1 WA and 10.0 t ha-1 PM increases pod yield by 23, 64, 68, 255, 41 and 123%, respectively. Combined use of PM and WA is recommended for ameliorating degraded Alfisol of southwest Nigeria and also reduced the quantities of PM and WA required for soil fertility maintenance. Source

A major element in Global System for Mobile Communication (GSM) system is the splitting of the system into cells to enhance frequency reuse and efficient coverage. As the mobile station moves from the coverage area of one cell to another, the first connection is broken and a new one is made without any interruption in service, in a process called handover. If this critical process is performed incorrectly handover can result in loss of the call. All the Base Transceiver Stations (BTSs) of the four providers of GSM service in Owo were located on the physical map of Owo town in Ondo State, Nigeria and coverage of each network provider was investigated. GSM signal strength analyzer was used for measuring and monitoring the received signal strength and Bit Error Rate (BER) from each BTS at six geographical locations in the town for a period of time. The effect of signal strength on handover decisions between cells within the same Base Station Controller (BSC) of same networks in Owo was assessed for each provider. © 2011 IEEE. Source

Experimental data on tillage requirement of cocoyam (Xanthosoma sagittifolium) are needed to identify the most suitable tillage methods for managing the fragile Alfisols of the humid tropics to ensure sustained productivity. Hence, five tillage methods were compared as to their effects on soil physical and chemical properties, and growth and yield of cocoyam on an Alfisol at Owo in the forest-savanna transition zone of southwest Nigeria. The experiment consisted of five tillage methods: manual clearing (MC), manual ridging (MR), manual mounding (MM), ploughing + harrowing (P + H) and ploughing + harrowing twice (P + 2 H) were used for three years at two sites in a randomized complete block design with three replications. In the first two years (2007 and 2008), P + H produced the least soil bulk density and highest growth and yield, whereas in the third year (2009), MC produced the lowest soil bulk density and best performance of cocoyam. Manual clearing produced the best values of soil chemical properties in 2008 and 2009. Averaged over the three years, P + H, MR and MM had lower soil bulk density hence better growth and yield compared with P + 2 H and MC. Over the three years MC, MM, MR and P + H increased cocoyam cormel yield by 10, 21, 23 and 32%, respectively, over P + 2 H.The corresponding increases in corm yield were 7, 15, 13 and 21%, respectively. The multiple regressions revealed that bulk density and moisture content significantly influenced the yield of cocoyam. Soil chemical properties were not significant. Bulk density rather than soil chemical properties dictated the performance of cocoyam in an Alfisol of southwest Nigeria. Soil quality was degraded by P + 2H. For small farms, either MR or MM is recommended while P + H is recommended for large-scale farming of cocoyam. © Cambridge University Press 2011. Source
