Název v původním jazyce

The effect of soil application of superabsorbent polymers saturated with nutrients on selected growth parameters of maize in drought conditions

Popis výsledku v původním jazyce

Superabsorbent polymers (SAP) seem to be suitable for optimization soil moisture conditions due to their ability to repeatably bound and release water and solutions with dissolved nutrients. Application of SAP contributes to better water management in soil and can prevent nutrients losses caused by leaching or volatilization. In this work, we focused on determination of the effect of SAP saturated with nutrients on maize selected growth parameters of maize in drought conditions. The results showed that soil application of SAP and fertilizers (SAP + NP or NPK fertilizer) had positive impact on observed growth parameters. In well-watered conditions, the highest increase of chlorophyll content in leaves was found after application of SAP + NP fertilizer, the increase was about 9.2% in compare to variant with NP fertilizer in term 30 days after sowing (DAS). Root electric capacitance (REC), which describes size of root system, was higher about 8% after application of SAP + NP than after application of NP fertilizer in drought conditions (term 58 DAS). SAP in combination with fertilizers had positive effect on dry matter production in well-watered conditions, it was higher than variants with only NP or NPK fertilization in term 58 DAS.
