A field experiment was conducted to elucidate the effect of integrated management on parthenium and yield components and yield of maize. The experiment was laid in a randomized complete block design with 14 treatments with a factorial arrangement. The highest parthenium density (87.80 m⁻²⁾ and dry biomass (764.61 g/m²) were recorded by weedy check while the lowest was in weed-free check (0.00 m⁻² and 0.00 g/m²), respectively. Late physiological maturity (140 days) was observed in 2,4-D+Straw mulching and weed-free check at Upper Bir and early maturity (133.00 days) were in weedy check at Lower Bir. 2,4-D+Twice hand hoeing and Butrazine + Straw mulching with 308.23 cm showed higher plant height at Lower Bir and least was in weedy check (265.96 cm) at Upper Bir. The highest numbers of kernels per ear, 1,000 kernels weight and grain yield (714.75, 438.33 g, and 11.40 tha⁻¹) were recorded on weed-free check at Lower Bir and the lowest was on weedy control (418.00, 438.33 g, and 5.29 tha⁻¹) at Upper Bir, respectively. The maximum dry biomass of maize was recorded for Butrazine + Straw mulching (13.51 tha⁻¹) at Lower Bir and the minimum was recorded for weedy control (7.68 tha⁻¹) at Upper Bir. Weed-free control (93.42%) and weedy control (68.95%) had the highest and lowest harvest index at Upper Bir, respectively. Therefore, using 2,4-D with straw mulching could provide good control of parthenium, economical, and ultimately better yielded.

埃塞俄比亚阿姆哈拉国家区域州西 Gojjam 区百草属 (Parthenium hysterophorus L.) 的综合管理及其对玉米 (Zea mays L.) 产量构成和产量的影响

进行田间试验，阐明综合管理对玉簪属植物和产量构成以及玉米产量的影响。试验采用随机完整区组设计，有 14 个处理，因子排列。杂草检查记录的最高百合密度 (87.80 m ^-2)和干生物量 (764.61 g/m ² ) 而最低的是无杂草检查 (0.00 m ^-2和 0.00 g/m ^{2 )}）， 分别。在上比尔的 2,4-D+秸秆覆盖和无杂草检查中观察到生理成熟晚（140 天），在下比尔的杂草检查中观察到早熟（133.00 天）。2,4-D+两次手锄和 Butrazine + 稻草覆盖 308.23 cm 显示下 Bir 的植株高度较高，而上 Bir 的杂草检查最少（265.96 cm）。在下比尔的无杂草检查中记录的每穗粒数、1,000 粒重和谷物产量（714.75、438.33 g 和 11.40 tha ^-1）最高，最低的是杂草控制（418.00、438.33 g 和5.29 tha ^-1 ) 分别在上比尔。玉米的最大干生物量记录为 Butrazine + 秸秆覆盖（13.51 tha ^-1) 在下比尔和最低记录在上比尔的杂草控制 (7.68 tha ^-1 )。无杂草控制 (93.42%) 和杂草控制 (68.95%) 分别在上比尔的收获指数最高和最低。因此，将 2,4-D 与秸秆覆盖结合使用，可以很好地控制百合，经济，并最终提高产量。
