Nutrient monitoring of eggplant transplants

Eggplant transplants require low fertility of 100 to 150 ppm N. Plants prefer a pH within the range of 5.8 to 6.5. This range prevents low substrate pH induced iron (Fe) and manganese (Mn) toxicities which occurs if the pH drifts lower than 5.5. Substrate pH values above 6.5 can also inhibit Fe availability and result in the upper foliage developing interveinal chlorosis (yellowing).
