A field experiment was carried out during winter (Rabi) seasons of 2012-13 and 2013-14 at research farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal with the objectives to study the weed control practices in no-tilled dibbling maize within rice residues. The experiment consisted of eight treatments, comprising of varying doses of 2,4-D (post-emergence treatment), atrazine with sequential application as pre-emergence and post-emergence treatment, pendimethalin followed by atrazine, weedy check and complete weed-free treatments, laid out in randomised block design (RBD) with four replications. Highest weed control efficiency and lowest weed index values were registered by  atrazine 1.0 kg/ha as pre-emergence + atrazine 1.1 kg/ha as post-emergence. The dominant weed flora were the broad-leaved weeds Polygonum persicaria, P. pensylvanicum, P. orientale, and the grasses Digitaria ciliaris, Setaria glauca. Among the weed control practices, season long weed free condition recorded the highest grain/kernel yield of maize (9.52 and 10.6 t/ha) during both the years, which was statistically at par with atrazine 1.0 kg/ha as pre-emergence + atrazine 1.1 kg/ha as post-emergence (9.3 and 10.4 t/ha) and atrazine 0.75 kg/ha as pre-emergence + atrazine 1.1 kg/ha as post-emergence (9.07 and 10.12 t/ha). The atrazine 1.0 kg/ha as pre-emergence + atrazine 1.1 kg/ha as post-emergence gave maximum net return of (` 93,650/ha and ` 1,21,050/ha) and maximum net return per rupee invested (1.88 and 2.31).
