Effects of plant density on Rosmarinus officinalis L. and first tests of mechanical transplanting

Research output: Contribution to journalArticlepeer-review


Tests for evaluating the agronomical response of Rosmarinus to four plant densities were carried out from 1998 to 2001, on a local ecotype of Rosmarinus, in an area having the typical soil and climatic conditions of the Sicilian inland hilly environment.Data about biometric characteristics (plant height, number of stems per plant, fresh and dry yield), the ratio between leaf weight and dry weight and the ratio between stem weight and dry weight, both expressed as percent, were monitored.Moreover, essential oil analyses were carried out for each plant density.The results showed that the plant density positively influenced the fresh and dry yield, while it negatively affects the number of stems.For each plant density comparisons between manual and mechanical transplanting were carried out. The mechanical transplanting with a one row transplanter showed values of working capacity and productivity seven to ten times higher than those obtained with the manual transplanting. The highest working productivity was recorded for the highest plant density.
