Abstract
In this study we investigated the suitability of horticultural main organic root substrate materials (peatmoss, coir) for the development proper root substrate for working with bulb onion transplanter. We investigated seedling sprout ratio, growth and characteristics (bulk density, root substrate cohesion) those are suitable for mechanical transplanting by mixing with inorganic materials(red clay etc.). Although both seedling growth and root substrate bulk density were similar in peatmoss and coir based root substrates, we found that peatmoss mixing had higher root substrate cohesion compared to coir mixing. We assume that higher cohesion properties of peatmoss based root substrate will give more weight of root part during mechanical transplanting of young onion seedlings in the field. Because of this, we suggest that peatmoss is the appropriate ingredient for developing root substrates for working with bulb onion transplanter.
