The productive yield of hydroponic green maize fodder was evaluated for implementation in livestock production systems. Nine treatments were evaluated with four repetitions, using a completely random design with bifactorial arrangement. The variables were measured: plant height, hydroponic green forage yield, dry matter and gross protein (%). Where the highest yields were obtained in terms of dry matter with 2.30and 2.16 kg/m 2 in the variety Guayape with 4 and 0 g of 12-24-12 NPK. In raw protein with 15.94 and 15.14% in the varietyRoundup Ready NK603 with 4 and 6 g, demonstrating that these varieties with fertilisation levels implemented can be used in the production of hydroponic forage as they contain high content of raw protein with a range >14.5 % and with acost benefit ratio exceeding 1.21 U$D.
