Comparisons of weed community, soil health and economic performance between wheat-maize and garlic-soybean rotation systems under different weed managements.

ABSTRACT: This study compared the impacts of different weed managements on weed community, soil health and economic performance between the wheat-maize (WM) and garlic-soybean (GS) rotations. A total of four treatments (H₀T, tillage without herbicide; H₀T₀, without both herbicide and tillage; HT, both herbicide and tillage; HT₀, herbicide without tillage) were designed for both rotations. A total of 16 weed species were recorded in the WM rotation, with life forms of 62% for annuals, 12% for annual + perennial and 20% for perennials. While in the GS rotation, there were 17 weed species, with 71% being annuals. When crop rotation changed from WM to GS, the topsoil layer seed bank (0-5 cm) decreased by 137%. GS rotation always had higher earthworm densities
