Abstract/ Executive Summary:

In 1995 an observation trial was conducted in BRRI farm, Gazipur to find out the adaptability of WSR cultivation and its performance in Aman season under rainfed condition. BR11 was used for this trial. Seed rate was 110 kg/ha and fertilizer doses were 80-60-40 kg/ha of NPK respectively. Whole amount of PK were applied during final land preparation. After final land preparation the sprouted seeds were sown in the puddle field. Nitrogen was applied in 4 equal splits. First split was applied after 15 days of sowing. The second and third applications were done at early vegetative and panicle initiation stage respectively. Two weeding were done manually. Basudin was applied during vegetative stage to control insects. No irrigation was needed due to sufficient rainfall in this season. The mean plant height and panicle length were 105 and 24 cm respectively. The mean plants per sqm were 256. The average grains per panicle were 126 of which 25 were unfilled. The average yield obtained from the observation plot was 4506 kg/ha which was an encouraging yield for WSR in Aman season. The results of observation trial revealed that WSR could be adapted in Aman season. The farm should be well drained to drain out the excess rain water at crop establishment period.
