Abstract :
This research was conducted to investigate the reaction of three maize hybrids (Zea mays L.) to herbivores in Poldokhtar (south of Lorestan). The experiment was a factorial based on randomized complete block design with four replications. The main factor included H1 = control (non-herbicide), H2 = Eradicans (before planting) and H3 = Alachlor (after planting and before salting) and the sub factor including three hybrids V1 = 704, V2 = 499 and V3 = 640. The results showed that herbicides had a significant effect on grain yield, ear length and ear diameter. The highest grain yield was obtained fromAlachlor herbicide treatment with 7785 k/ ha and this treatment showed that it is more efficient than other treatments. The results also showed that interaction of weed and cultivar on 1000 seed weight, dry matter yield, grain yield, number of seeds in row and height to ear were significant. The highest grain yield was obtained from the interaction between Alachlor herbicide and 704 (8335 k/ha). And showed that the 704 has a high capacity to increase performance. In general, the results showed that the use of Alachlor treatment (after planting and before germination) due to the effective control of weeds, especially in the early growth period of maize, with a low competitive ability, and the use of the 704 variety The reason for the high capacity of production can be recommended in southern Lorestan, especially Poldokhtar.
