PENGUJIAN BEBERAPA KONSENTRASI PACLOBUTRAZOL DENGAN WAKTU APLIKASI BERBEDA PADA TANAMAN TOMAT (Lycopersicum esculentum Mill.)
Abstract: The aim of this
study to improve tomato production by granting several concentrations of
paclobutrazol and its application on differents time. This study was used a
completely randomized factorial design 4 x 2 in three replications. The first
factors was the paclobutrazol concentrate (K) in four levels (k0= No
paclobutrazol, k1= 300 ppm, k2= 600 ppm and k3= 900 ppm. The second factors was
the application time of paclobutrazol (A), in two levels (a1= 20th days after planting, a2= 30th days after planting). The data were analyzed using analysis of
variance and mean separations with Duncan’s New Multiple Range Test at the 5%
level. The result showed that there was no interaction between the
paclobutrazol concentrate with the application time of paclobutrazol on
variable of tomato observed. Paclobutrazol concentrate or its application time
effected to plant height and number of flower. Paclobutrazol 300 ppm to 900 ppm
concentrate hold up tomato plant height and reduce the number of flower.
Application of paclobutrazol 20th days after planting hold up tomato plant
height and reduce the number of flower.
