The experiment was carried out in the Experimental Area of ​​the Plant Genetic Improvement Sector of the Agricultural Sciences Center of the Federal University of Alagoas (SMGP-CECA-UFAL), in the year 2013, where periods of control and weed coexistence of sweet potatoes were evaluated. The experimental design was carried out in randomized blocks in the 3 x 14 factorial scheme with three replications, with three sweet potato genotypes in 14 periods of interference, and distributed in seven control periods (0, 10, 20, 30, 40, 50 and 60 days after planting - DAP), from which the weeds were controlled, and seven coexistence periods, from which the weeds coexisted with the crop. The evaluations consisted of sweet potato genotype shoot samplings at 30, 60, 90, and 120 days after planting (DAP), using one working area plant per plot in each evaluation stage. In the determination of the leaf area, a mechanical integrator was used, and to obtain the shoot dry mass, the material was taken to a forced air circulation oven at 65 ºC for 72 h, with subsequent weighing. According to the results, it can be observed that, in the coexisting treatments, there was a significant reduction in the shoot growth rates, in comparison to the treatments in which the weeds were controlled, especially the reduction of the leaf area at 120 DAP, where clone 6 and Sergipana showed a reduction of 89.0% and 88.0%, respectively. As for Clone 14, this reduction occurred at 90 DAP, at about 52.0%, which was less expressive, whereas in relation to the shoot dry mass, clones 6, 14, and the Sergipana variety showed a reduction at 120 DAP of 86%, 51%, and 46%, respectively.

The objective of this study is to develop a cattle monitoring system for tracking cattle combating rustling in extensive grazing areas, grazing reserves, grazing routes and ranches. The system is majorly made up of a collar that consists majorly of a GSM & GPS module. This system would not only combat cattle rustling activities but would also serve as an anti-theft system. When cattle wearing the collar exits the virtual fences, an SMS containing the coordinates of the collar is sent to the cattle farmer enabling him to check the cattle’s position and ward off a potential danger or theft. SMS alerts are also sent to the farmer also when the battery of the collar is low, the collar is unbuckled from the cattle and when the farmer calls the collar to know its location. This system would provide cattle farmers with the opportunity to fully monitor their herd within a particular grazing region

A geoelectric investigation of groundwater prospect at Omitogun Estate, along Benin/Ilesha express way Akure, within the basement complex of southwestern Nigeria was carried out with a view to providing information on the geoelectric characteristic of the subsurface sequence, bedrock topography, subsurface structural features and their hydrogeologic significance, in order to identify aquifer units and determine possible areas for groundwater potential zones. The study involved the use of Schlumberger vertical electrical sounding data at thirty (30) stations. The vertical electrical sounding data presented as field curves were interpreted quantitatively by partial curve matching method and computer iteration technique. Fracture resistivity map, aquifer resistivity map, aquifer thickness map and overburden thickness map were generated from the results. Groundwater potential map was also generated from the integration of these maps using multi-criteria decision analysis (MCDA). The study area has been classified into low, medium, high groundwater potential zones and the results from well data across the entire study area were used to validate the accuracy of the groundwater potential map. From the results obtained, it could be concluded that the study area is generalized to be of low groundwater potential.

The increasing quest for economic development and demographic demand has led to rapid forest decline and degradation of the forests in Nigeria. Forests are lost yearly through the industrial, commercial and other urban-related activities. This is currently impacting on the environment and accelerating degradation and depletion of its forest cover and resources. Deforestation is an ongoing phenomenon in Nigeria and is becoming more pronounced with increasing population and urbanization. The effects of deforestation have led to a decline in forest cover, forest degradation, impoverishment of the soil and general deterioration in environmental conditions. However, the inestimable values of forests in promoting sustainable livelihood, industrial raw materials availability, food security, medicine and health care researches, cannot be over emphasized, hence the need for imbibing strategies for reversing the trend and promoting measures that could enhance sustainable management of Nigerian forests. Thus this review paper provides integrated insight into the strategies viable for reversing the deforestation trend and the effective management of the wide varieties of Nigeria’s natural vegetation

Conflicts within continental Africa have been a recurring decimal in the socio-political, economic, and cultural history of the people of Africa from time immemorial. In the last few decades, especially from the mid-twentieth century, African societies have been undergoing difficult times vis-à-vis interstate and intrastate conflagrations. This study attempts to provide a critical glimpse into the nature of the concept of conflict, its inherent characteristic features and the various types of conflicts applicable to the African continent. It relied on the qualitative content analysis of secondary sources of data, and the psychocultural conflict approach was adopted as the tools of analysis for the study. The paper argues that conflicts in the different African regions are both interstate and intrastate; the latter remaining the dominant form of conflict in Africa with an increasing amount of actors. Also, the essay holds that conflicts have undermined Africa’s development by causing the loss of human lives and economic resources, dislocation of people, and increased poverty rate. The paper, therefore, recommends the need for a context-specific and multi-layer conflict resolution, management and prevention initiative(s) encapsulating a broad based local, regional and international collaboration between all concerned stakeholders; the unfettered adherence to the rule of law; and the governments’ need to place as their basic attention the welfare of the citizens through well guided policies so as to increase citizens’ living standards and support human capital development.
