چکیده

Cereal rye (Secale cereale L.) is an important cover crop species in the United States. It has potential to minimize soil erosion, reduce nutrient leaching, decrease fertilizer inputs, improve water after termination, and enhance organic matter. also efficient tool for weed suppression (up 100% under ideal conditions), which achieved through several mechanisms. Reported biomass production estimates ranged from 0.9 20 t ha−1 different environments; benefits were observed all these scenarios, though extent of significantly differed across studies, indicating presence multiple mechanisms with cereal crops. These can be competitive [competition space (i.e. mulching effect), water, nutrients light] or non-competitive (allelopathy, reduction temperature, light quality). Such a variety make it excellent integrated management both conventional systems. In this review, we summarize analyze published information on by rye. First, outline physiological characteristics that many provide. Second, review four suppression, are generally considered leading ones. Third, three mechanisms, applications not yet fully understood agricultural Finally, implications identify knowledge gaps directing future research topic. This article protected copyright.
