&description=A field experiment was conducted at Bangladesh Jute Research Institute sub-station, Monirampur during 2017 and 2018 cropping seasons to find out the appropriate age of plants for cutting and spacing effects on quality seed yield of tossa jute. Seeds of the variety O-9897 were sown in three separate beds (each of 10×4 m<sup>2</sup>) at 15 days interval from March to April for raising mother plants. The top and stem cuttings were collected from mother plants prior to flowering stage and used as study materials. The experiment consisted of three ages of cutting viz. 105 days, 120 days and 135 days; and two spacing viz. 15ʺx5ʺ and 18ʺx4ʺ. The Random Complete Block Design (RCBD) was used in a factorial layout. Results showed that seed yield was greatly influenced by ages of cutting. The highest seed yield (655.83 kg ha<sup>-1</sup>) was obtained from cutting of 120 days of mother plant. Significantly higher seed yield (628.55kg ha<sup>-1</sup>) was recorded from 18ʺx4ʺ spacing. The seed yield was significantly affected due to the interaction of ages of cutting and spacing. The cuttings planted from 120 days of mother plant in 18ʺx4ʺ spacing gave the highest seed yield of 680.67 kg ha<sup>-1</sup> in tossa jute variety O-9897. Correlation studies revealed that seed yield was positively correlated with plant height and number of pods plant<sup>-1</sup>. The character number of branches plant<sup>-1</sup> was negatively associated with seed yield. To enhance yield status of tossa jute, the characters plant height and number of pods plant<sup>-1</sup> could be used as selection criteria.&picture=http://www.aascit.org/aascit/decorators/img/journal/892.jpg)
