Described is a hydroponic system wherein a feed formulation comprising a plant's nutritionally effective amount of at least one amino acid, which upon uptake, becomes a substantial source of nitrogen for said plant, is applied to the foliage of the plant, and the roots of the plant are in contact with an incomplete water solution that comprises less than the plant's nutritional nitrogen requirements. The feed formulation, methods of feeding a plant or plant seed, and plants produced thereby are also described. 1. A method of growing a leafy vegetable plant through its foliage comprising:applying a foliar feed formulation to a leaf of said leafy vegetable plant, wherein(a) the roots of the plant are in contact with an incomplete water solution or inert medium that is essentially free of the plant's nutritional nitrogen requirements; and(b) the foliar feed formulation comprises a nutritionally effective amount of at least one amino acid, which upon uptake, becomes a substantial source of nitrogen for said plant;wherein said leafy vegetable plant grown using said foliar feed formulation develops in a manner that is comparable to a plant of the same type having been grown so that it absorbs its nutritional nitrogen requirements through its roots.2. The method of claim 1 , wherein the amino acid is selected from the group consisting of the D- claim 1 , L- or racemic forms of alanine claim 1 , beta-alanine claim 1 , arginine claim 1 , asparagine claim 1 , aspartic acid claim 1 , carnosine claim 1 , cysteine claim 1 , glutamine claim 1 , glutamic acid claim 1 , glycine claim 1 , histidine claim 1 , isoleucine claim 1 , leucine claim 1 , lysine claim 1 , methionine claim 1 , phenylalanine claim 1 , proline claim 1 , serine claim 1 , taurine claim 1 , threonine claim 1 , tyrosine claim 1 , valine claim 1 , citrulline claim 1 , citrulline malate claim 1 , or mixtures thereof.3. The method of claim 1 , wherein said foliar feed formulation further comprises an effective amount ...
