Potassium nitrate turned out to be the preferred priming treatment for melon seedlings

The aim of the work was to evaluate the response of melon seedling in order to reduce post-transplant stress and thus maximize biomass production as a strategy for managing melon crops. Priming was performed in 150 mM of different solutions: KNO3, NH4NO3, (NH4)2SO4 and NaCl. Fertigation with NH4NO3 did not eliminate the effect of previous priming treatments. Seedlings primed with KNO3 showed the highest total fresh and dry biomass, mainly due to their higher metabolic activity and their greater leaf area (Table 1). Potassium nitrate outperformed the other priming treatments in this experiment.
