Zeolite and Ascophyllum nodosum-Based Biostimulant Effects on Spinach Gas Exchange and Growth

Among the innovative practices of dry-farming in recent years, possibility combined use biostimulants and soil conditioners is assuming an important role. In a preliminary pot experiment, this study aimed to verify effects Ascophyllum nodosum-based biostimulant zeolite applied on gas-exchange spinach growth. We also monitored water content effect uptake. Pots were filled with which added. Spinach plants grew into pots subjected four treatments: (1) plus at percentage 1%, (2) biostimulant, (3) 1% (4) bare as control. The A. led higher (+10%) content, highlighting positive role allowing good uptake by plant. Plant growth was not changed, while only photosynthesis showed increase equal 6% plants. These results are discussed variation according modification induced treatments. can be considered strategy improve storage and, same time, cultivation terms sustainability.
