Efficacy of sequential sprays of different fungicides against early blight Alternaria solani (Ellis and Martin) in potato Solanum tubrosum L.



S. A. More, M. R. Deshmukh, Madhuri Katkar



Potato is one of the world's fourth most important food
crop belongs to family solanaceae. More than one billion peoples
consume potatoes and richest source of energy highest dry matter, energy
and edible proteins. The field experiments on Efficacy of sequential
sprays of different fungicides against early blight Alternaria solani
(Ellis and Martin) in potato Solanum tubrosum L. was conducted during
kharif season on potato (cv. K. Pukharaj) for consecutive three years.
The experiment was laid out in RBD design with 6 treatments and 4
replications. The results revealed that spray of Chlorothalonil 75 WP
(0.25%) @ 2.5 gm/ liter of water followed by Hexaconazole 5 EC (0.05%) @
0.5 ml /liter of water and then Chlorothalonil 75WP (0.25%) @ 2.5
gm/liter of water at 10 days interval was found significantly superior
in controlling the early blight on potato The yield differences due to
spraying of fungicides were significant and the highest yield (18.10
t/ha) was obtained in same treatment.

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...

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...
