Plant measurements where performed from 25th of May till 1st of September 2003.
During the experimental period, every 15 days, 8 plants per treatment harvested
destructively and the leaf area (flowering shoots and bent shoots), the fresh and dry
weight were measured. Empty spaces were filled by plants of the same size. The first
destructive measurement was on the day the treatments start and the total sum of harvests
was 7. Furthermore, three times a week flowering shoots were harvested and flower
production and quality (number, length, fresh and dry weight) were measured. Results
were statistically analyzed as a randomized block design by Analysis of Variance using
the package of SPSS
