Assessment of triasulfuron on weed dynamics and yield of transplanted rice (Oryza sativa L.)
Journal Title: Journal of Applied and Natural Science - Year 2018, Vol 10, Issue 3
Abstract
A field experiment was managed during kharif season of 2014 in G. B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) to assess the outcome of applying dissimilar rates of triasulfuron on the transplanted rice (Oryza sativa L.) associated weeds. Treatments composed of triasulfuron at three different rates, metsulfuron methyl, ethoxysulfuron, 2, 4-D with 2 checks (weed free and untreated). Experiment was carried out in Randomised block Design with 8 treatments and 3 replications. Grassy weeds, broad leaf weeds and sedges were observed during the crop growth period. Triasulfuron at 12 g ha-1 proved most efficient in controlling weeds at 60 and 90 days after transplanting (DAT) with 44.4 % and 59.6 % WCE respectively. Minimum weed dry matter (65.1 g m2) was observed with triasulfuron at 12 g ha-1. Out of all the herbicidal treatments, triasulfuron at 12 g ha-1 gave the paramount grain yield of rice (5786 kg ha-1) which was significantly surpassing all other herbicidal treatments, while it was minimum in metsulfuron methyl at 4 g ha-1 (4417 kg ha-1).
