2019
Margit Olle
The purpose was to assess the effect of silicon on the leaf lettuce production. The experiments in the greenhouse were carried out in the spring 2014 at the Estonian Crop Research Institute. Treatments: 1) stabilized silicic acid treatment; 2) control. Si treatment (2 mL L–1 of silicic acid): First spray, when 1 true leaf was present; second spray was two weeks after spray 1; third spray was two weeks after spray 2. The pH of spray solution was 5.5. pH of spray solution was 5.5. Control plants were treated with water. The plants were 26% higher in Si variant. The width of leaf lettuce was 32% larger in Si variant. In leaf lettuce the phosphorus content was 14% higher, the content of calcium was 32% higher, the content of magnesium was 12% higher in Si variant than in control.
