EFFICACY OF UPH 210 B AGAINST WEEDS IN TRANSPLANTED PADDY
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
A field study was conducted on efficacy of herbicides against weeds in transplanted rice during Kharif 2015 and summer 2016 at Agricultural Research Station, Dhadesugur, University of Agricultural Sciences, Raichur, Karnataka, India. The weeds, which were dominant in trials field are Echinochloa sp. Panicum repens, Cynodon dactylon and Leptochloa chinensis among grasses, Eclipta alba and Ludwigia parviflora as broad leaf weeds and Cyperus sp. as sedge. Results revealed that, significantly higher grain yield of rice was recorded in weed management treatments over weedy check. However, among weed management herbicidal treatments, pre-emergent application of UPH 210b @ 2500 ml/ha was at par with its lower dose i.e. application of UPH 210b @ 2000 ml/ha, found to be significantly superior and on par with recorded higher grain yield followed by twice hand weeding at 15 and 30 days after transplanting. Moreover, maximum cost benefit ratio was observed in plots treated with UPH 210b along with twice hand weeded check
