Current cultivation practices and weed composition in durian orchards in Cai Be district, Tien Giang province

Abstract

This study investigates weed management in durian orchards in Cai Be district, Tien Giang province (prior to the administrative merger), aiming to assess biological indices, weed distribution, and factors affecting cultivation efficiency. Weed samples were collected from surveyed areas, and biological characteristics of weed species composition, biodiversity indices, and weed coverage were analysed. The results indicate that large planting areas and cultivation techniques play crucial roles in management, but dependence on natural water sources and limited fertilisation experience remain challenges. A total of 12 weed species were recorded, with Axonopus compressus and Commelina communis being the most prevalent, with densities of 24.00±0.71 and 20.00±0.75 plants/m², respectively. The Shannon-Wiener index (H’) revealed high biodiversity in An Huu, An Thai Trung, and Thien Trung communes.
Weed coverage was uneven, with higher densities in An Cu and An Thai Trung communes, while Hau My Trinh and Hoa Khanh communes exhibited more uniform distribution. An Thai Dong commune showed dominance by specific species. It is essential to implement uniform weed management measures across wide areas rather than focusing on specific points to ensure long-term and sustainable effectiveness, and to consider potential weed species for use as
livestock feed.
