The study was conducted to determine the effects of varying photoperiods and amounts of fertilizer used on the growth and flowering performance of chrysanthemum. Findings showed that the different lengths of photoperiod did not significantly affect plant height, number of runner seedlings, and good inflorescence at high elevation. On the other hand, it had a significant effect in all the three aspects at low elevation. Shorter photoperiod (normal day length decreased by two hours) increased plant height and number of good inflorescence harvested. Artificially increasing the length of photoperiod by two hours significantly increased the production of seedlings. Plants were significantly taller at higher elevation than at lower elevation. Average number of seedlings per plant for high and low elevations was almost similar. The application of different amounts of fertilizer did not affect the number of runner seedlings and good inflorescence at high elevation. However, increasing the amount of fertilizer applied also increased plant height. At low elevation, different rates of fertilizer application had no effect on the number of good inflorescence harvested. However, increasing the amount of fertilizer applied also increased the plant height and the number of runner seedlings. Photoperiod and rate of fertilizer application had no significant relationship with the number of damaged inflorescence at high elevation. However, shorter photoperiod significantly reduced the number of damaged inflorescence at lower elevations
