摘要: Abstract The important tropical root and tuberous crops cassava (Manihot esculenta), sweet potato (Ipomoea batatas), yams (Dioscorea spp.), the aroids (especially Xanthosoma Colocasia spp.) represent an source of relatively inexpensive carbohydrates to large sectors population in areas. One or more are normally a staple rural communities typically grown on small-scale subsistence farms. current status agroecology research these crops, including productivity under polyculture systems, resource (water, nutrients, light, space) utilization, tolerance environmental stress, pest dynamics response habitat manipulation, alternative cultural practices, is reviewed this paper as they relate performance agricultural systems. development technological recommendations improve tropics dependent understanding import...
