Abstract

A field experiment was conducted during the kharif season of 2022 to determine the effects of various weed management practices on weed dynamics and productivity of dry direct-seeded rice at Agricultural College Farm, Bapatla. The experiment was laid out in a Randomized complete block design (RCBD) with six treatments and four replications. The lowest weed population, dry weight, highest percent weed control efficiency and productivity of rice were recorded by the hand weeding treatment. Among all the herbicidal treatments, the lowest weeds count, weeds dry weight and highest percent weed control efficiency and high productivity of rice were recorded under treatment PE Bensulfuron methyl 0.6% + Pretilachlor 6% @ 0.66 kg/ha fb PoE Bispyribac-Na 10% @ 25 g/ha at 20 DAS fb PoE Ethoxysulfuron 15% @ 18.8 g/ha + Fenoxaprop-P-Ethyl 6.7% @ 55 g/ha which can be recommended to the farmers.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
