Estimation of Unavoidable Yield Losses in Certain Rabi Pulse Crops Due to the Root-Knot Nematode, Meloidogyne javanica

Field trials were laid down to estimate unavoidable yield losses in chickpea, fieldpea and lentil crops due to infestation of rootknot nematode, Meloidogyne javanica at Indian Institute of Pulses Research Kanpur. Paired plot treatment method was employed to know the extent of yield losses of these crops infested with root-knot nematode in sandy loam soils. Carbofuran and phorate @ 2 kg a.i./ha were used to check the root-knot nematode population in the infested fields of chickpea, fieldpea and lentil respectively. Results indicated that root-knot nematode had incurred unavoidable yield losses to the tune of 25.6% in chickpea and 15% each in pea and lentil.
