Plant-Parasitic Nematodes Associated with Forage Legumes Planted in Fallow and into Living Grass Sod
Journal Title: Egyptian Journal of Agronematology - Year 2017, Vol 16, Issue 1
Abstract
The capability of legumes to fix and provide sufficient nitrogen for crop production has encouraged re-appraisal of cropping systems that utilize relevant forage legumes. However, plant-parasitic nematodes (PPN) can damage forage legumes but differently according to forage legume production systems. Therefore, this study determined the population levels of PPN associated with three different production systems. Different species of forage legumes were planted in fallow soil and into living grass sod of two species; 'Pensacola' bahia grass and 'Tif-81' bermuda grass. Thirteen genera of PPN were associated with one or more cultivars of twelve forage legumes in one or more of three locations in Alachua County near Gainesville, Florida, USA. No significant difference (P ≤ 0.05) was found in the nematode population levels among clover cultivars overseeded in dormant bahia grass or bermuda grass sod. However, when clover cultivars were planted in fallow plots, significant differences (P ≤ 0.05) occurred in population levels of Meloidogyne spp. Also, significant differences (P ≤ 0.05) occurred in populations of Meloidogyne spp. and Criconemella spp. among the three experiments.
