الملخص EN

To evaluate the economic viability of integrated weed management (IWM) in onion, a simple economic analysis was conducted to estimate revenues, net return and cost: benefit ratio based on onion bulbs yield.

Treatments included crop density (high 408163 plants / ha and low 190474 plants / ha), four methods of nitrogen fertilization (broadcast on soil surface, banded 10 cm deep on the top of crop rows, spray on crop foliage and unfertilized control), and four weed management treatments included oxyflourfen (goal 10%) 0.5kg a.i / ha, pendimethalin (stomp 45%) 1.0 kg a.i / ha + hand weeding 45 days after transplanting (d.a.t.) and hand weeding twice 30 and 60 d.a.t.

and untreated control.

Results indicated that planting with high adequate crop density with banded nitrogen fertilizer and suitable and appropriate integrated weed management (pendimethalin (stomp45%) 1.0 kg a.i / ha + hand weeding 45 days after transplanting) led to increased onion bulbs yield with reduced total cost.

The estimated cost : benefit ratio for this management strategy was 1 : 8.
