Abstract
The experiment was conducted at Jute Research Regional Station (JRRS), Kishoreganj and Jute Research Regional Station (JRRS), Rangpur during 2024 to determine the optimum sowing time depending on the jo- condition (The soil condition when it is ready for seed sowing) available after rainfall of three kenaf varieties viz: HC 95, BJRI Kenaf 3 (Bot Kenaf) and BJRI Kenaf 4 (KE-3). The experiment was laid out in RCBD with three replications. Crops were sown on two different dates in each location based on rainfall patterns. In Kishoreganj, sowing was carried out on 29 March and 21 April, while in Rangpur it was done on 25 March and 17 April. These sowing dates were considered as treatment factors in the experiment. All, the crops were attained standard cultural practices and harvested at 120 days after sowing. The results showed that all the yield contributing parameters like plant population, plant height, base diameter, fibre yield and stick yield, differed significantly due to sowing times and variety. HC-95 sown on 29 March gave significantly higher fibre (3.60 tha-1) and stick yields (7.25 tha-1) in Kishoreganj. In Rangpur, HC-95 gave maximum fibre yield (3.70 tha-1) and stick yield (7.40 tha-1) when sown on 25 March.
