【 摘 要 】

Weed is one of the factors that disturb maize cultivation. Each maize variety has specific characteristics which will lead to weeds diversity in particular farm. This study aimed to identify the effect of maize variety on weed diversity on maize's growth phases. The research was conducted from March to July 2016 in Banguntapan, Bantul, Yogyakarta, Indonesia. The field research was arranged by using Randomised Complete Block Design with three replications. The treatments were maize varieties, consist of 12 levels: 'Bisi 18', 'Bisi 2', 'Pertiwi 3', 'NK 22', 'NK 33', 'DK 959', 'P23', 'DK 771', 'DK 95', 'Bima 19 Uri', 'Bisma', and 'Sukmaraga'. The results showed that at four weeks after planting (WAP) the most of weeds were growing on varieties 'Bisi 18', 'NK 33', 'P 23', and 'DK 95', there were 14 species. Bulbostylispuberula and Cyperusrotundus were growing on all maize varieties with the highest SDR on 'Sukmaraga' and 'DK 959'. At six WAP, weeds that grew, most consists of four species of sedges, six species of grasses and 24 species of broadleaf. While at the age of eight WAP, the weeds that grow at least on 'NK 33' that were 13 species and the most on 'P23' that were 21 species. Dactyloctenium aeghypthium having highest SDR in all maize varieties except Bisi 18. The highest SDR value on Bisi 18 was Boerhaavia erecta about 16.23%.
