Abstract

Weeds are one of the most limiting factors in CHICKPEA production, which their non-chemical management is very important in ecological agriculture. An experiment was conducted during 2005-2006 at Agricultural Research Station of Khorram-abad, to study the effects of WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING time and planting density on dry matter dynamics of WEEDs and CHICKPEA. Five WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING times (non WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING, WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING in three, five, and seven weeks after tertiary branching and WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING during whole growing season) and four plant densities (20, 40, 60 and 80 plants m-2) were evaluated using a factorial experiment based on a randomized complete block design with three replications. The results suggested that, the frequency of wild buckwheat, ramping fumitory, volunteer wheat, wart grass and wild safflower were more than the other WEEDs. The effects of WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING time and plant density on dry matter of CHICKPEA and WEEDs were highly significant (p<0.001). Delay in WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING led to significant increase in the dry matter of WEEDs. Increase in WEEDs dry matter, especially at seven weeks after tertiary branching led to reduce in the CHICKPEA dry matter. Although increase in plant density led to increase in the CHICKPEA dry matter and decrease in the WEEDs dry weight. The results of this experiment indicated that, planting autumn CHICKPEA at 40 plants m-2 along with WEEDING/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> WEEDING in five weeks after tertiary branching might be appropriate for reducing WEEDs competition and improving CHICKPEA production under conditions similar to this experiment.
