Abstract
The effect of six substrate mixtures 1) peat + perlite (M1), 2) Peat + Vermiculite (M2), 3) Peat + Sand (M3), 4) Peat + Perlite + vermiculite (M4), 5) Peat + Perlite + Sand (M5), and 6) Peat + vermiculite + Sand (M6) and three container volumes (100cm3, 65cm3 and 35cm3) on the quality of cucumber, melon and watermelon transplants was studied through the two seasons 1999 and 2000. Results showed that M3 mixture was generally similar to, if not better than, M2 mixture for its effect on transplant growth. The two media followed by M6 significantly increased shoot height, leaf area, shoot FW and OW, root FW and OW and root length, for the three crops under investigation. The mixture M1 produced the least transplant growth:
Results also showed that container with the largest volume presented the best results for all tested growth parameters. The best transplant quality in terms of shoot height, leaf area, shoot FW and OW, root length and root FW and OW was obtained with 100cm3 containers compared with 65cm3 and 35cm3. Cucumber and melon transplants derived from 100cm3 cells had 2 times and watermelon had almost 1.7 times jlreater shoot OW than those derived from 35cm3 cells. In general containers of 100cm in combination with M3 or M2 followed by M6 produced the best transplant growth. Transplant grown in M3 had the highest level of N in cucumber and melon, and the highest level of K, Fe, Mn in watermelon. It was also noted that the larger the container, volume, the higher the concentrations of most nutrients in cucumber, melon and watermelon transplants.
