摘要

Weeds are among the essential living component affecting the wheat production. This research analyzes the effect of soil incorporated fresh and dry leaf residue of Ageratina adenophora on emergence of weeds and production of wheat (Triticum aestivum L.). Soil was collected from wheat fields and divided into three parts; one part was amended with fresh leaves of A. adenophora (100 g kg−1); second part was amended with dry leaves of A. adenophora (100 g kg−1) and third part without leaf residues was used as control. Soil was placed in plastic trays and replicated three times in glasshouse to record weed diversity and growth. The findings demonstrated that the foliage (fresh and dry) amendment suppressed the weeds establishment without having significant impact on wheat growth. The higher weed count in dry leaf residues amended soil might be due to the availability of sufficient water and nutrients as they emit volatile compounds into the pores of soil which attain restrictive concentrations to affect weeds maturation. The FLT (up to 40.51% and 70.8%) suppressed weed growth and biomass whereas wheat showed moderate increase in biomass (12.59% in FLT; 57.39% in DLT) and yield components. However, higher growth, biomass and yield of wheat in dry leaf residue amendments as compared to control indicated a possibility of using dry leaf residues of A. adenophora as mulch in wheat crop for sustainable agriculture. Therefore, the production practice using invasive plants for weed control will likely consist of combining limited amounts of herbicides with crofton weed residues.
