This study investigated the applicability of horticultural media with recycled coir substrates the growth of Chinese cabbage (Brassica campestris L. ssp. Pekinensis) and lettuce (Lactuca sativa L.) crop. The six different types of coir based substrates were A, Coir 45: Perlite 35: Vermiculite 12: Zeolite 8 (%), B, Coir 55: Perlite 25: Vermiculite 12: Zeolite 8 (%), C, Coir 65: Perlite 15: Vermiculite 12: Zeolite 8 (%), D, Coir 75: Perlite 5: Vermiculite 12: Zeolite 8 (%), E, Coir 85: Perlite 5: Vermiculite 5: Zeolite 5 (%) and F, nursery media (control). The pH and Electric conductivity of the horticultural nursery media were 6.06–7.00 and 0.45–1.10 dS/m-1, respectively. The nursery media containing coir substrates had higher level of Total N, Ca, K, Mg and P than those without coir. Additionally, it was observed that the growth of Chinese cabbage was the best on D (containing 75% coir) while that of lettuce was the best on E (containing 85% coir). In general, when substrates containg a higher percentage of coir were used, the growth of Chinese cabbage and lettuce was ideal. Additionally, the P, Ca, and Mg content in both plants was not significantly altered by the amount of coir present in the media. However, with an increase in the amount of coir substrate, the chlorophyll, N, and K content was increased. After harvesting, there was no significant difference in the chemical properties of the horticultural nursery media of both plants. Thus, it can be suggested that, coir substrate after a single use could be recycled as horticulture nursery media.
