The experiment was carried out to study the effect of various planting methods and weed competition periods on onion seedling. Split plot arrangement with Randomized Complete Block Design (R.C.B.D.) was used in the study. The data were recorded on the weed density m-2, weed density (%), weed biomass m-2 weed dry weight percentage, days to complete germination, plant height (cm) and bulb diameter (cm). Convolvulus arvensis, Chenopodium album, Rumex crispus, Desmotachya bipinnata and Euphorbia heliscopia were the most common weeds present at the experimental site. Days to germination were significantly affected by sowing methods while various weed competition periods influenced the plant height Maximum height (26.12 cm) was measured in weed free treatment 20 days after sowing. The bulb diameter was not affected significantly by the planting methods and weed competition periods.
