Incidence of major insect pests of blackgram at different dates of sowing was studied at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Ishurdi, Pabna with six sowing dates initiating from August 07 to September 11, 2007 at an interval of seven days. Hundred percent of the sampled plant was found to be infested by stemfly and flea beetle while their intensity of infestation varied significantly. The lowest stem tunneling per plant by stemfly, damaged leaf by flea beetle and pod borer infestation was observed in Aug 7 sowing followed by Aug 14 and 21. The maximum number of thrips was found in early plantings (up to 21 Aug) whereas minimum in late plantings. The study indicates that early planting (up to 21 August), in general, gave lower infestation by the insects than late plantings. Significantly the highest yield was obtained from Aug 7 followed by Aug 14 and Aug 21, while Sept 11 and Sept 04 had the lowest yield. Download
