Abstract:The objective of this study is to investigate the interaction of R, B and FR from phosphor-converted LED on the growth and yield of the sweet basil and holy basil. Seedlings were grown in the chamber with a continuous supply of 200 µmolm-2 sec-1 PPFD of R and B. Several ratios were applied as R:B.3.5 and 7.0 without FR and R:B.3.5 with FR 50 µmolm-2 sec-1. The photo period was 16/8 h. The results found that R:B.3.5 with FR50 significantly increased the growth rate by 49-114%, the plant height by 64-137%, the s… Show more
