Effect of hydroponic and conventional production systems on plant growth performance and nitrate content of green coral lettuce (Lactuca sativa var. Crispa)

Overfertilization on leafy vegetables could accumulate high nitrate content. Exceeded recommended limit of nitrate content can cause detrimental effects on the environment and human health, such as methemoglobinemia and stomach cancer. Green coral lettuce (GCL) is a leafy vegetable commonly grown un...
