Cultural Methods and Mineral Content of Eggplant (Solanum melongena) Fruit

Mineral content in edible portions of vegetables may be affected by cultural methods. This study was conducted to determine if fertiliser rate and irrigation regime affected mineral (N, NO2, NO3, P, PO4, K, SO4, Ca, Fe, Na, Mg, and Mn) of eggplant (Solanum melongenaL, cv Black Bell) fruit. The experiment on a Bernow fine‐loamy, siliceous, thermic Glossic Paleudalf soil at Lane (OK, USA) with three fertiliser rates and three irrigation regimes. The data were analysed as a split‐plot with harvests as the sub‐plot. All P was accounted for by PO4. Levels of NO2 and NO3 comprised
