Glyphosat and Paraquat herbicides weed control and yield effect after emergence in cotton
Journal Title: Asian Journal of Agriculture and Biology - Year 2017, Vol 5, Issue 4
Abstract
Response of various post emergence herbicides at different levels i.e. Round up was applied as 4.75 lha-1, 2.75 L ha-1 and 1.75 L ha-1 (Glyphosat), Gramaxone 20EC (Paraquat) as 2.55 lha-1 and untreated (no spray) were field experimented against cotton cultivar CIM-473 under field condition at CCRI cotton research institute, Multan. Significant Control of weeds and increase in yield and yield contributing factors were observed. It was indicated that the highest significant yield, number of bolls, fresh weed biomass, dry weed biomass, plant height and weed control were obtained by using Round up (Glyphosate) @ 4.75 L ha-1 as compared to other treatments including untreated (control). Average boll weight was not significant among treatments but significant against control. The highest net profit was obtained by the Round up 490 G/L when treated @ 4.75 L ha-1 than all other treatments.
