Abstract

Population buildup of rice root nematode, Hirschmanniella oryzae on basmati rice cultivars in relation to the different dates of transplanting and two spacings revealed that there was more buildup of H. oryzae in crop transplanted in middle June or late July. Spacing of 15x15 cm and 20x15 cm in Basmati 370 and Pusa 615 had no effect on population buildup of H oryzae. Comparatively higher population of H. oryzae was observed in Pak Basmati and Basmati 37 O. Basmati 385 supported minimum population of H. oryzae.
