Abstract:
A field experiment was conducted during the Kharif season of 2013 and 2014 at
KVK, South Tripura to evolve effective weed management practices for upland direct seeded
rice. The experiment consisted of 12 treatments laid out in Randomized Complete Block Design
with three replications. The predominant weed flora observed in the experimental field were
Amaranthus viridis, Oldenlendia corymbosa, Spilanthes acmella, Ludwigia parviflora, Cleome
rutidosperma, Malvestrum coromondalianeum among the broad leaf weed, Digitaria
sanguinalis among grasses and Cyperus iria among sedges. The result of the experiment
reveals that weed free treatment recorded lowest weed dry weight for all types of weed and
higher yield and yield attributing parameters of upland rice followed by pendimethalin + one
hand weeding. All other treatments were significantly superior to weedy check in all respect.
