PERTUMBUHAN DAN PRODUKSI TIGA VARIETAS TANAMAN PAK CHOY (BRASSICA CHINENSIS L.) PADA BERBAGAI NILAI ELECTRICAL CONDUCTIVITY LARUTAN HIDROPONIK
Abstrak: Pak Choy is one of
the economic valuable vegetables in Indonesia. This research was aimed to
increase the growth and productivity of three varieties of Pak Choi through the
variation of electrical conductivity (EC) rates in the hydroponic solution. The
complete randomized factorial was used in ths research. They were three
varieties of he variety of Pak Choy (V1 is Green, V2 is Green Fut Choi,
V3 is Green Fortune) and four EC rates {1.5 (E1), 2.0 (E2), 2.5 (E3), 3.0 (E4)
mS/cm}. The variety of Pak Choy gave significant differentiation to all of the
affect to the numbers of leaves, root length and the numbers of chlorophylls.
The regression analisys was showed that increasing of the mg EC rates would
increase the number of chlorophylls of all Pak Choi varieties. The interaction
between Pakchoi varieties and the EC rates show in canopy diametesr, that the
combination in V2, differences were found in E4 and E2 and the best value was
found in V2E4 at 10 DAP (Day After Planted). In 15 DAP, canopy diameters in V2 and
V3 were not different. In V1, differences were found among E1, E2, and E4. The
best value was found in V2E3 at 15 DAP.
