Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 16
Abstract
Lack of reliable information about distribution of weeds in agricultural fields in Khorramabad of Iran is one of the most important causes of low crop yield. Studies on floristic composition of weeds in an agricultural zone could lead to a better weed control management. The goal of this article was study the floristic composition of Chickpea weeds in Khorramabad, during 2007. Sampling was done on 9 point of each field according to W method. Per plate of all weed species were counted separately. Accordingly, species abundance, species density uniformity at the level of farm and each region was determined. Among the 70 species observed in the level of Chickpea fields, most Frequency are species Gallium aparine and vicia vilosa whit 93.8 percent. Weeds of Vaccaria garndiflora, and Cerastium dichotomum with frequency of 75 and 59.4% respectively were the two others prevalent species. Mean weed density of Gallium aparine 10.3 plants/m2 was significant completely difference than the other weeds. Mean density of Vaccaria grandiflora and Vicia villosa were 4 and 3.4 plant/ m2 , respectively.
