Abstract

Different REGRESSION MODELS are used to determine weed ECONOMIC DAMAGE THRESHOLD. An experiment was conducted in 2002 in Shirvan area to determine the threshols of economic damage of effective WEEDS to WHEAT yield using Swinton method. Using a quadrate (50cm x 50cm), data were collected from destroyed and non-destroyed samples. To define inter and intraspecific competition in WHEAT-weeds competition, 1/W and l/LnW REGRESSION MODELS showed to better fit the data. According to these models, from among Avena ludoviciana, Erysimum sp., Polygonum aviculare, Rapistrum rugosum, Chenopodium album, Salsola kali, and Sonchus sp., reduction effect of only Avena ludoviciana, Salsola kali, and Rapistrum rugosum on WHEAT yield was significant. Therefore, the threshold of economic damage was determined for these WEEDS, being about 6.16 TCL (Total Competitive Load); equivalent to 6.16 Avena ludoviciana, 13.02 Salsola kali, and 27.80 Rapistrum rugosum plants per unit area.
