Since there is no leaching and salts tend to accumulate over time in the growing media, nutrient concentrations should be lower than applied by other irrigation systems. However, fertilizer requirements for subirrigated sugarcane (Saccharum species hybrid) pre-sprouted seedlings (SPSS) are not yet available. Our objective was to evaluate two FS concentrations to produce SPSS in an ebb-and-flow system: 33% and 67% of the recommended concentrations for seedlings produced using overhead irrigation. We tested three cultivars (IACSP95-5000, IACSP95-5094 and IAC91-1099) in terms of crop growth and macronutrient content of stems and leaves. There was no effect of FS concentrations on 1st ligule height, diameter, and dry weight. Irrigation with both FS concentrations resulted in seedlings with adequate nutritional status. Substrate electrical conductivity (EC) increased for treatment irrigated with FS 67%, indicating excessive fertilization. For FS 33%, substrate EC remained stable. FS with concentration of 33% can be used to produce SPSS in ebb-and-flow benches, resulting in adequate plant growth and fertilizer savings. aIrrigation aPlant nutrition aSoilless culture aSugarcane aCana de Açúcar aFertilizante aIrrigação aMuda aFertilizer solution aNutrition guidelines aSoilless production1 aFERRAREZI, R.
