In order to investigate the effects of chemical and integrated weed management on yield and yield components of grain maize and weed population, the study has been conducted as a randomized complete block design with three replications in 2018-19 in Shavar Research Center in Shavar region of Shousha city. Treatments include unweeded (control), hand weeding, 1.5 liters of atrazine, 1 liter of atrazine i straw mulch, 175 g of ultima, 150 g of ultima i straw mulch, 1.5 liter 2,4-D i MCPA, 1 liter 2,4-D i MCPA i straw mulch, 1.5 liters cruise, and 1 liter of cruise i straw mulch. Results show that the highest grain yield has been obtained in hand weeding treatment as well as 1 liter of ccrausies eo, fi h satrrvawes tm inudlcexh, b y1. 51 4li.t4e arsn do f1 c3r.u2i st eh ash-!o, rwe stpheec thiivgehlye.s tT vhaeluhei g(h5e5s.7t %ho), ٠ lfiocllo١wl eydie bldy i'1s .r5e lcitoerds do fin 2 h, 4a-nDd iw eMedCiPnAg tarenadt m1.e5n tl it(e3r1s .5o tf hataraziiiInne by 53.6% and 47.7%, respectively. In terms of weed population dynamics, hand weeding, and 1 liter of cruise i straw mulch cause the greatest decrease in weed population and dry weight which reduce crop competition and increase productivity. In general, based on the results, the adoption of integrated approaches (chemical i cultural i mechanical) can make a significant contribution to increasing corn yield and reducing environmental pollution.
