English Abstract

A field trial was carried out during the growing season, 2015, at the research farm of Field Crops, College of Agriculture, University of Duhok, Kurdistan Region at Sumail county.

A randomized complete block design (RCBD) was applied with two factors plant densities at three levels (100,80 and 60 plants/plot of 3m2 which corresponded to 33.33, 26.6 and 20 plants.m2) and four methods of weed control (check , hand hoeing, Propyzamide herbicide 50% WP, at 1.5kg a.i.ha-1and Haloxyfop10.8% EC at 0.108 kg a.i.ha-1 ; with three blocks.

The results revealed that the Haloxyfop was the most effective method for controlling narrow leaf weeds, which recorded 1.88 weeds per 3m2 plot, and the only significant differences was noticed between Haloxyfop and Propyzamide herbicides.

However Propyzamide resemble control and hand hoeing treatments.

The interaction of chickpea densities with weed control methods was also significant; the most effective combination was recorded for the herbicide Haloxyfop at 33.33 chickpea plants.m2.

It gave the lowest number of narrow weed leaf (0.33), while the highest number of narrow leaf weeds (25) was recorded for Propyzamide herbicide at 26.6 chickpea plants.m2.With respect to the number of broad leaf weeds, there was no significant differences between chickpea plant densities on this trait, while weed control methods was significantly varied, hand hoeing was the most effective method in diminishing this trait followed by Haloxyfop.

Also no significant differences were noticed for chickpea densities on broad leaf dry weight per plot, however hand hoeing was the most effective method in reducing dry weight of broad leaf weeds at all densities of chickpea plants, but the inferior was at 20 chickpea plants.m2 (90.5 g); meanwhile the highest number was recorded for the combination of Propyzamide at 20 chickpea plants.m2 (529.0 g).

Total dry weight of weeds per 3m2 plot, was significantly influenced by chickpea densities, the highest the density of chickpea (33.33) plants per m2 the lowest the total dry weight per plot of 3m2 (259.5g).

The combination of hand hoeing at 20 chickpea plants.m2 was most effective methods in reducing total number of weeds (23.0) followed by Haloxyfop at the same density of chickpea plants.
