Study of artificial irradiation arrangement and pinching age on chrysanthemum

Abstract

Abstract The study was conducted to determine the effect of artificial irradiation setting time, pinching age, and their interactions on the growth and yield of chrysanthemum. The research method uses factorial Complete Randomized Group Design with 2 factors. The first factor is the treatment of growth cut point age (U) consisting of three age levels (1, 2, and 3 weeks after planting), and the second factor is the setting time of artificial irradiation (W) consisting of four levels (1, 2, 3, and 4 hours per 35 days). The results showed that the treatment of cutting point of growing age had significant effect to very real on all parameters observed except in secondary branch diameter, while the treatment of artificial exposure time was not significant on all parameters observed. The interaction had a significant effect on very real on all parameters observed except in the secondary branch diameter. The intercept between the cutting point of age 1 week after planting and artificial irradiation setting 4 hours per 35 days resulted in the average weight of flower stalk, flower diameter, and economic weight of the highest secondary branches respectively 127.398 g, 6.733 cm, and 122.489 g, increased by 29.63%, 30.69%, and 33.30%, respectively when compared with the lowest treatment.
