This combination is profitable for farmers; however, root-knot nematodes (Meloidogyne spp.) can cause severe damage to these crops. To ensure compatibility with earnings and sustainability, new methods are required to reduce crop damage under the current production systems. Accordingly, cultural methods designed to reduce nematode damage to crops in upland farming were examined
