An investigation on prevalence of rice root nematode in the farmer rice fields under natural condition was carried out. Farmer fields were located under Jamalpur district, Tangail district and Mymensingh district. Nematodes were isolated by following Bangladesh plate technique (modified Whitehead and Hemming tray method, 1965) and were counted per liter soil at booting, flowering, milking, soft dough, hard dough and harvesting stage. The highest nematode population 1196.7 L-1 soil was recorded in Madarganj having soil pH 5.9 sandy loam texture, 0.92% OM and higher N status followed by 524.4 L-1 soil in Sutiakhali having soil pH 5.4, loamy texture and 1.06% OM maximum nematode population 965.3 L-1, soil was observed at soft dough stage. |

Population dynamics of Hirschmanniella oryzae were determined per 5 g root basis from the roots at different plant growth stages by survey of irrigated rice in Madarganj (Jamalpur district), Madhupur (Tangail district), Sutiakhali, Nilukkhar char and Bangladesh Agricultural University Farm (Mymensingh District) during December 2001-March 2002. The highest nematode population 30.5/5 g root was recorded in BAU Farm having soil pH 5.6 sandy loam texture, 1.88% OM and balanced fertility status followed by a population 24.8/5 g root in Madhupur having soil pH 4.4, loamy texture and 0.99 % OM peak population was observed at soft dough stage covering booting, flowering and milking stage. The reduction in nematode population was recorded from hard dough to mature stage. |
