Utilization of foliar fertilizer as an alternative medium for enlargement of Vanda orchid plantlets before acclimatization

Abstract

This study aims to obtain an appropriate and inexpensive alternative media combination for the growth of Vanda hybrid orchids prior to acclimatization. Experiment using Factorial Randomized Block Design. The first factor is the type of media (Vacin -Went and foliar fertilizer ) and the second factor is the addition of organic matter (coconut water composition, sweet corn composition, tomato composition, BAP, NAA and without organic matter or PGR). The results showed that the interaction of treatment on plant height was only seen at 18 weeks after treatment, while the number of leaves could be seen earlier at 16 weeks after treatment. The independent effect of organic matter and PGR on the number of leaves has been seen since the age of the plant 10 weeks after treatment, while the plant height was only seen 16 weeks after treatment. Independent treatment of growing media had no effect on height and number of leaves up to 18 weeks after planting. The use of foliar fertilizer media with the type of organic material composition being tested can be suggested as an alternative growth medium for plantlet growth, not significantly different from vacin-went with BAP media.
