| To study integrated weed management in maize cultivar, KSC 704, a field experiment was conducted at the Mahidasht Agricultural Research Station in Kermanshah, Iran., , during spring and summer of 2006. Split plot arrangement in randomized complete block design with four replications was used.The main plots were row spacing (55, 65 and 75cm) and sub-plots were soil application herbicide (EPTC), non-selective herbicide (Paraquate), mechanical weeding with cultivator, hand weeding and control. Analysis of variance and means comparison indicated that weed biomass in 75 row spacing, in comparison to 55 and 65 cm row spacing, increased by 107% and 105%, respectively. Grain yield in 55 and 65 cm row spacings as compared with 75 cm row spacing increased by 17.6% and 22.5%, respectively. In conclusion, grain yield in EPTC, hand weeding, Paraquate and cultivator treatrments increased by 50%, 47.5%, 31.1% and 28%, respectively. Weeds were controlled better in EPTC and 65 cm row spacing . |
