Abstract

Unreliability and unpredictability of rainfall amount and temperature fluctuations have negative impact on agriculture production especially in Africa where coping mechanisms are limited. The future of rainfed agriculture is uncertain more so on banana production among the smallholder’s farmers due to climate variability. This study examined the extent of rainfall and temperature changes on banana production among smallholders’ farmers in Mount. Kenya region of Kenya from 2009 and 2017. The sites were purposively selected to include Imenti south (Meru County) and Mukurweini sub-counties (Nyeri County) where banana production has been practiced since 1990. A sample size of 381 respondents was identified using simple random sampling. Production and climatic (rainfall and Temperature) data were sourced from Horticultural Crop Directorate and Kenya Meteorological Department respectively for the stations adjacent to the study sites for the study period. Results showed decreasing trends on rainfall amounts while temperature increasing trend. Study found that rainfall increase does not necessarily translate to increased production while temperature level of about 18.50C gave the maximum yields. Majority of the respondents (42.8%) in the study region admitted to have changed the land use and type of crops they have been farming during the study period whereas 30% changed from other crops to banana farming. Banana acreage and production in both sub-counties have been increasing during the study period. The County and National government should provide irrigation as a coping mechanism to banana production due to the declining rainfall and increasing temperature in the region. We recommended provision of weather information on the onset of the rainfall period and distribution within the seasons in order to respond to the effects of climate variability.

Abstract

This study aims to determine the effect of different concentrations of liquid fertilizer with hydroponic planting media on kale production. The research method used was Randomized Completely Factorial Design with 2 factors: POC cocoa skin and cocoa poc added with cow dung. This study consisted of 16 treatment combinations each repeated 2 times. So there are 32 units of the whole experiment. Parameters observed include: percentage of growth, plant height, number of leaves (leaf), leaf area (), measuring leaf color, wet weight of harvest, wet weighted weighing, root length measurement. Based on the results of research that has been carried out can be concluded as follows: Provision of liquid organic fertilizer from cocoa leather and organic fertilizer liquid cow dung on the growth and production of kale plants showed unequal generative growth. The dosage of liquid organic fertilizer (POC) given by kangkung plantation has no effect on the increase of observed parameters from plant height, leaf number, leaf color, leaf area, and wet weight of the plant. In the excess of nutrient elements

Abstract

Non-motor symptoms such as depression and in later phases dementia are common features of Parkinson’s disease. For the first time in Iran, the present study aims to examine the effects of deep brain stimulation of the subthalamic nucleys (STN-DBS) on cognition and mood through neuropsychological assessment of patients with Parkinson’s disease. Stimulation of the subthalamic has no negative effect on the short-term cognitive status of patients with Parkinson’s disease, and improves depression. Precise psychological evaluation helps better recognition of the effects of this kind of surgery, which may be useful in providing quality services for those who will be candidates for this surgery in the future.

Abstract

The environmental impacts of waste disposal of polyethylene bags and seasonal variation of polyethylene disposal in Gusau City of Zamfara state, Nigeria was investigated. General public waste disposals from homes, schools and daily markets, were randomly selected for data collection. The data showed that polyethylene waste is generated more in the dry season than the wet season. The result also showed that table water sachet has 75% disposal. This is because, sachet water is cheap and consumed throughout the year with very little seasonal variation while at homes and markets also, displayed a very interesting pattern. The study revealed that in the market, polyethylene for table water sachets (10%) was the least, followed by ice cream sachets (6%), assorted items (5%) and biscuits wrappers (4%). On the other hand, the results showed that, at home, polyethylene for assorted items was the highest (61%), closely followed by biscuit wrappers (20%), table water sachets (14%) and ice cream wrappers (5%) respectively. Polyethylene waste poses various threats to public health and adversely affects flora and fauna as well as the environment especially when it is not appropriately collected and properly disposed. And based on this research, it was found that most of the public do not know the advantages, disadvantages and the health effects of rampant and improper disposal of polyethylene bags. It is concluded that aggressive campaign and enlightenment of the masses on the threats posed by polyethylene bags pollution should be carried out to prevent further negative environmental impact.

Abstract

Malaria-curing trees species were identified among the urban tree species previously identified in Ijesa Region of Nigeria. 25 communities were randomly selected from the region and used for this study. In each community, four adults who have lived in the community continuously for at least 10 years were purposively selected and interviewed on the medicinal values of the urban trees in the region through the use of a semi-structured questionnaire matrix. The ethnomedicinal recipes of the identified malaria-curing tree species were documented. Results obtained revealed that respondents were conscious of the medicinal values of the urban trees. 11 out of the 34 indentified tree species were used for malaria control. The malaria-curing trees were 344 out of 2156 urban trees sampled in the region. This was considered low in view of their medicinal value thus stressed the need to encourage urban tree cultivation among the populace. The malaria plant-based medicine was prepared using simple technology that mostly involved boiling in water. Thus their preparations are attainable by everybody. The extractions of most of the identified species were mostly non-annihilative but extractions predatory and annihilative extractions occurred in four species. Sustainable strategies to improve on urban tree cultivation were proposed.

Abstract

An inventory of tree biodiversity was carried in Ekiti State University, Ado-Ekiti, Nigeria, which is an institution where ecological and economic roles of trees are disseminated. The study involved the use of a stratified sampling technique to carry out a survey of trees species in the University. The campus was divided into four strata - Road side (A), Car parks (B), Office area (C), Student halls/ religion area (D) - and each stratum was further sub-divided into sub-strata. All the trees within each sub-stratum were identified to species level with their scientific, local and family names and they were counted and recorded. The relative frequency, relative density and relative abundance of the identified species were determined. Similarities indices and indices of diversity were determined on the tree species sampled among the strata. The results obtained revealed that a total of 27 tree species, belonging to 17 families were sampled in the campus. The family Caesalpiniaceae has the highest number of species. Some of the identified tree species were found in multiple and dual strata while some occurred in only one stratum. A total of 838 tree individuals were obtained. The most frequently occurring species were T. grandis, G. arborea and P. longifolia with 298, 181 and 149 individuals respectively. The indices of similarities among the strata were low. However Strata A and B as well as A and C appeared to be similar in tree composition. Strategies that would improve and maintain tree composition in the University campus were proposed
