Abstract

The aim of the study was the evaluation of different concentrations of silicon effect and high levels of manganese in the nutrient medium on the yielding and nutrient status of hydroponically grown lettuce cv. ‘Sunny’. Plants were grown in rockwool in closed fertigation system with nutrient solution recirculation. The following levels of silicon were studied: 0.21, 0.42 and 0.63 mg∙dm-3. The source of silicon was fertilizer contain choline-stabilized orthosilicic acid (ch-OSA) (0.6% Si). Control combination was plants without Si nutrition. Silicon nutrition significantly influenced on content of macroelements in aboveground parts of plant: decreasing of nitrogen (for 0.21 and 0.63 mg Si∙dm-3), increasing of: phosphorus (for 0.42 and 0.63 mg Si∙dm-3), potassium (for 0.21 and 0.42 mg Si∙dm-3), calcium (for all the Si-treatment) and magnesium (only for 0.21 mg Si∙dm-3) comparing with control. In case of microelements Si significantly reduced zinc content (only in case 0.63 mg Si∙dm-3) and iron (for all the Si-treatment), with lack of significantly influence in case of manganese, copper and sodium. Increasing silicon nutrition significantly and positively influenced on plant yielding.
