Herbicidal efficacy of some natural products and mulching compared to herbicides for weed control in onion fields
In two field experiments, the effect of some weed control treatments (citric acid at the rate of 10, 15 and 20%, acetic acid at the rate of 20, 30 and 40%, oxadiargyl, oxyflurfen, rice straw mulch, hand hoeing and an unweeded check control treatment) on weed growth and onion productivity in sandy...

| Summary: | In two field experiments, the effect of some weed control treatments (citric acid at the rate
of 10, 15 and 20%, acetic acid at the rate of 20, 30 and 40%, oxadiargyl, oxyflurfen, rice
straw mulch, hand hoeing and an unweeded check control treatment) on weed growth
and onion productivity in sandy soils at the Agricultural Experimental Station of the National
Research Centre, Egypt was studied. The results indicated that all weeded treatments
reduced the dry weight of broadleaf, grassy and total weeds as compared with the weedy
check. Oxadiargyl, followed by two hand hoeing, rice straw mulch and acetic acid 40% recorded
the greatest weed control efficiency. Insignificant differences were noticed between
these treatments. Applying rice straw mulch increased bulb length, bulb diameter, bulb
weight and onion yield by 67.52, 57.55, 45.74 and 66.22% over the weedy check, respectively.
The highest values of N, P and K were obtained from rice straw mulch treatment followed
by hand hoeing, oxadiargyl and acetic acid 40% treatments. It may be concluded that
farmers can certainly depend on mulching or acetic acid at 40% instead of using chemical
herbicides especially in organic farm systems for controlling onion weeds. |
