Effect of Pre and Post Emergence Herbicides to Weeds Control in Corn Field

Effect of Pre and Post Emergence Herbicides to Weeds Control in Corn Field



Mohammad Hassan Baniasadi



The aim of this comparative study was evaluation of pre and post
emergence herbicides Effect to control weeds in corn field. Experiment
was conducted as a randomized complete block design with three
replications. The treatments included: no weed control, weed, complete
mechanical control, Nicosulfuron herbicides (two liters per hectare) as
pre- and Erradican 4 liters per hectare as post emergence. Some
properties were studied such as the dry weight of weed species, plant
height, seed number on the cob, seed yield, 1000seed weight, biological
yield. Totally, result showed that application of herbicide led to
reduction of damages caused by weeds, also, it was determined that using
of Nicosulfuron+ Erradican had highest effect on weed control in
compare to Nicosulfuron or Erradicanaplication. application of
Nicosulfuron, Erradican, Nicosulfuron+ Erradican and complete
mechanical control showed 45, 38, 58 and 84% seed yield increasing in
compare to no weed control.

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...
