Effect of sugarcane mulch thickness on emergence of four vine species: results of a pot trial* [Full subscriber]

Abstract The impact of different thicknesses of cane trash blanket on the emergence of four common vine species in sugarcane fields (pink convolvulus – Ipomoea triloba, red convolvulus – I. hederifolia, siratro – Macroptilium atropurpureum and centro – Centrosema molle) was investigated in a pot trial in Mackay, Queensland. The experiment also compared the effect of trash blanket versus inert mulch to assess if allelopathic compounds impact on vine germination. A high level of trash (equivalent to 18 t/ha) reduced the final number of emerged vine seedlings by 66% on average compared to a low level of trash (6 t/ha)…
