Abstract: The effect of different stecklings size (22.5, 3.0 and 33.75 cm) on the seeds production of radish under sub- tropical climate of Azad Kashmir were studies. It was observed that the number of the leaves, leaf length, secondary branches of plant, number and length of pods per plant, 1000 grains weight and average seeds yield per hectare was highest in plots of larger steckling size 33.75 cm as compared with plots having smaller stecklings size 30.0 and 22.5 cm while non-significant differences were observed in primary branches and number of seeds per pod in all treatments. The larger steckling size 33.75 cm proved best for the better seed plant development and higher seed yield of radish crop under sub-tropical conditions of Azad Kashmir.
