Optimal Environmental Conditions for Yam Storage in South East (Tropical) Zone of Nigeria

Optimal Environmental Conditions for Yam Storage in South East (Tropical) Zone of Nigeria



E.A. Udom, S.I. Oluka, P.C. Eze



Yam storage methods in Nigeria were studied, evaluated
and compared. Among the storage methods studied, evaluated and compared
include designed barn, traditional barn, house and pit storages. The
parameters taken to assess their performance were tuber weight loss,
rotting, sprouting and pest infestation after fourteen (14) weeks of
storage. Designed barn storage methods with weight loss of 29.6996kg was
compared to other storage methods with weight loss value of 58.199kg
(pit storage) 46.800kg (house storage) and 47.8002kg (traditional
storage) from the big tuber sizes (1.5 – 1.8kg). From the small tuber
size (0.7 – 0.9kg), the weight loss recorded from each storage methods
included, designed barn 24.2004kg; pit storage44.8994kg; house storage
43.4994kg and traditional barn 46.6004kg. Rotting was recorded nil from
designed barn for both big tubers and small tubers and 10 tubers each
were recorded from pit house and traditional barn for big tubers, pit
storage recorded 20 tubers and others recorded nil for small tubers.
Records on sprouting indicated the following numbers of tubers from each
storage methods. From the big tubers set, designed barn had 20 tubers
sprouting within 14 weeks duration but pit had 30 tubers while house
storage had 20 tubers and traditional barn 30 tubers sprouted. From
small sized tubers, records on sprouting indicated the following,
designed barn nil, pit storage 80 tubers, house storage 40 tubers and
traditional 60 tubers. Data collected from each storage facility were
statistically analyzed and compared using Completely Randomized Design
(CRD), ANOVA, standard deviation and LSD). Designed storage structure is
recommended for use by yam farmers to alleviate their losses after
harvest and to help farmers prolong the life span of their produce for
future use as food, planting materials, industrial use and commercial
uses.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
