Abstract
This study was carried out to investigate the effect of several subtrates on the growth of cucumber and tomato seedlings. Cucumber and tomato seeds were sown in plug trays that were filled with eight differenct kinds of substrates. One of them was filled with recycled rockwool by 100%. The other six were mixed with used rockwool media:several ratios of recycled rockwool+peatmoss (1:1, 1:2, 1:3, v/v) and recycled rockwool+chestnut wood ships (1:1, 1:2, 1:3, v/v), and the last was 100% chestnut wood chips. The growth of cucumber and tomato seedlingsin 72 plug tray was better in recycled rockwool+peatmoss (1:2, v/v) substrates that the others tested. CEC 9cation exchange capacity) and EC was a little higher in mixed substrates that blended with organic media. But 100% chestnut wood chips and mixed ones with recycled rockwool inhibited severely the growth of seedlings, especially in tomatos. Therefore, it is suggested that the recycled rockwool be capable of utilization to raise seedlings of cucumber and tomato.
