Abstract

In order to determine the ECOLOGICAL EFFECTs of concentration and time of herbicide application for weed control in CORN, a field experiment under natural infestation of weeds was conducted in Shahr-e-Rey (Jafar Abad) and Varamin Farms. The experiment was conducted as split plots in the basis of completely randomized blocks design in 3 replications. Using ATRAZINE herbicide contains 4 levels (0, 1, 2 and 3 Kg. ha-1) as main factor and 3 different herbicide times application (After planting and before germination, 3 weeks after planting and 6 weeks after planting) as sub factor were considered. The results of variance analysis indicated that, the effect of timing and concentration of herbicide application and interaction of them on all measured traits (Plant height, stem diameter, ear CORN length, ear CORN diameter, number of rows per ear CORN, number of grains per row, number of grains per ear CORN, grain and total dry weight and grain yield) were significant. Two times of herbicides application, after planting and before germination and 3 weeks after planting had positive significant effect to the third timing of herbicide consumption. There were not significant difference between 2 and 3 kg/ha herbicide applications. Except in dry weight and grain yield traits which in the time after planting and before germination application for 3 Kg.ha-1 had better result, In other cases later herbicide application had less succesfully. Two or three kg/ha of atrazin after planting and before germination spraying showed positive results in weeds control during the first few days critical period of CORN growth.
