Effects of plant density on Rosmarinus officinalis L. and first tests of mechanical transplanting
2004
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 …
Increasing the effectiveness of aggregates for planting sugar beet stecklings to receive elite seeds
2019
Article Planting sugar beet stecklings with planting machine is one of the stages in the technological process of producing elite seeds. The analysis of the experience of using planting units for planting stecklings showed a number of disadvantages: poor quality of planting stecklings without spacing stability and the absence of parameter control; unregulated applying nutrients and granules of water preservation to the roots negatively affect the development of plants. The aggregate having openers of the planting device was designed, and the system of supplying the spray of nutrients and growth stimulator is envisaged. The technological process is conducted in the following way: during the …
