Abstract: An investigation was made to observe therninfluence of sowing methods and duration of weed competition on the productionrnof onion seedlings. The experiment was laid out in split plot arrangements withrnRandomized Complete Block Design (RCBD). The data were recorded on the weedrndensity m^-2, weed density (%), weedrnbiomass m^-2, weed dry weightrnpercentage, germination percentage, number of onion seedlings and seedling,rnweight. Sowing methods produced significant results in case of germinationrnpercentage. Statistically line sowing (9.524 kg) and weed free after 10 days ofrnsowing (10.40 kg) produced maximum seedling weight plot^-1.rnAs regards the weed density, the highest density of Convolvulus arvensis wasrnrecorded in the treatments. Besides, Euphorbia heliscopia, Chenopodium albumrnand Rumex crispus also declined the growth rate of onion seedlings.
