Abstract:

A field experiment was conducted at the research farm of SKUAST-J, Chatha Jammu, during the spring season 2013 to evaluate the efficacy of tembotrione (42% SC), a relatively new post emergence herbicide against mixed weed flora in spring maize. The experimental field was highly infested with Cyperus rotundus, Cynodon dactylon, Phyllanthus niruri and Digitria sanguinalis. Post emergence application of tembotrione @ 120 g ha-1 at 15 DAS not only reduced the total weed population, weeds dry weight and weed index but also increased the weed control efficiency, grain and stover yields which was at par with post emergence application of tembotrione @ 120 g ha-1 at 30 DAS and two hand weeding at 15 and 30 DAS. Highest net returns of `43, 975 ha-1 and B: C ratio of 1.88 were obtained with the treatment tembotrione post emergence @ 120 g ha-1 at 15 DAS followed by the treatment tembotrione post emergence @ 120 g ha-1 at 30 DAS of `43, 028 and 1.84, respectively.
