Abstract
The field experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, GKVK, Bengaluru during summer 2021 to evaluate the effect of new generation mesotrione herbicide on growth and yield of maize (Zea mays L.). The experiment consists of application of different doses of mesotrione herbicide as early post emergent (EPoE) and weed free check and unweeded control were replicated thrice in RCBD. Major weeds observed were Alternanthra sessilis, Borreria articularis, Euphorbia geniculata, Cynodon dactylon, Dactyloctenium aegyptium, Echinochloa colonum, Eleusine indica and Cyperus rotundus. Post-emergent application of mesotrione 48% SC @ 120 ml ai. ha-1 recoded higher kernel yield, stover yield of maize and BC ratio (6273 kg ha-1, 7583.7 kg ha-1 and 2.94 respectively) and it was on par with mesotrione 48% SC @ 144 ml a.i. ha-1 (6075 kg ha-1, 7430 kg ha-1 and 2.79 respectively). Weedy check recorded a kernel yield (3090.7 kg ha-1), lower stover yield (4096.3 kg ha-1) of maize and lower BC ratio (1.03) compared to other treatments.
