Weed is one of the major problems in maize production. To develop an appropriate weed management practice, a field experiment was carried out during 2017 and 2018 at Khumaltar. Twelve different treatments, Pendimethalin as pre @ 1.0 kg a.i ha-1, Atrazine 1 Metribuzine 0.5 Tembotrione post 0.2 followed by (fb) HW, fb + (early ) tank mixed, Straw mulch, free (2 HW) Weedy check (control) were evaluated Randomized Complete Block Design (RCBD) with three replications. The experimental plot size 12 m2 variety Manakamana -4 sown on 21 26 May respectively. seed rate used 20 ha-1 row spacing 60 cm plant to cm. Fertilizers dose 120:60:40 N:P2O5:K2O applied. Data crop growth, yields recorded analyzed. count biomass from meter square quadrat yield data taken net 5.4 m2. Results showed that height straw mulch maximum 294 density significantly influenced treatments. HW less weeds (52.8) highest (258.5) weedy check. lowest dry (9.3 g m-2). grain (7.6 Mt ha-1) found emergence. increased due application emergence 32.5% over Similarly, control efficiency (77.1%) BC ratio (2.46) also
