Influence of Weeding on the Performance of White Maize Varieties

The experiment was conducted at agronomy farm of Sher-e-Bangla Agricultural University, Dhaka from November 2017 to April 2018 investigate the influence weeding regimes on performance white maize varieties. comprised two varieties viz. YANGNUO-3000 and PSC-121, designated as V1 V2 respectively combined with four weed control treatments T0 = No weeding, T1 One hand 60 DAS (days after sowing), T2 40 T3 Weed free DAS. laid out in RCBD (factorial) three replications. PSC-121 showed superior terms plant height, leaf number plant-1, grains cob-1 (468.75), 100 weight (35.0837 g), grain yield (8.28 t ha-1), stover (6.56 ha-1) harvest index (55.58%) over YANGNUO-3000. In case treatments, highest (464.54), (37 (9.25 (7.46 were reported T3. All parameters studied found lowest T0. However, interaction, no single interaction other alternatives. But most cases V2T3 values regarding maximum (494.97) (38 g). (9.33 whereas, V1T0 (5.49 ha-1). density biomass (12.17 no. m-2 4.33 g·m-2) recorded efficiency (94.38%) also variety better density, WCE (46.32%).
