Title A name given to the resource Crescimento e nutrição mineral de milho forrageiro em cultivo hidropônico com soro de leite bovino Growth and mineral nutrition of forage corn cultivated hydroponically with serum of cow milk Creator An entity primarily responsible for making the resource Leila de Paula, Mário M. Rolim, Egídio Bezerra Neto, Tales M. Soares, Elvira M. R. Pedrosa, Ênio F. de F. e Silva Description An account of the resource Realizou-se este trabalho com o objetivo de avaliar a eficiência nutricional da forragem de milho e a utilização do soro de leite bovino em substituição à solução nutritiva no cultivo de forragem hidropônica de milho. O experimento foi conduzido em casa de vegetação em delineamento experimental inteiramente casualizado, com seis tratamentos e cinco repetições, sendo o tratamento controle representado por solução nutritiva convencionalmente empregada nesse tipo de cultivo; os demais tratamentos foram distribuídos em diferentes níveis de diluição (20, 40, 60, 80 e 100%) do soro de leite em água potável. A colheita foi feita 15 dias após a germinação, separando-se a biomassa da parte aérea da biomassa do substrato com as raízes. Determinaram-se a massa fresca e seca, os teores de macronutrientes (N, P, K, Ca, Mg e S) e micronutrientes (Fe, Cu, Zn e Mn), além dos elementos em níveis tóxicos (Na e Cl), tanto da parte aérea como do sistema radicular. O aumento nas concentrações de soro de leite promoveu redução na produtividade da forragem hidropônica, acréscimo nos teores de N, S e Zn, estabilidade no teor de K e redução do Ca e Mg, não apresentando efeito nos teores de P, Fe e Cu, na parte aérea, enquanto nas raízes ocorreu acréscimo nos teores de P, K, Ca, Mg, S e Cu.This research was accomplished with the objective of evaluating the nutritional efficiency of the use of serum of cow milk in substitution to the nutrient solution in hydroponic cultivation of forage corn. The experiment was carried out under greenhouse conditions in a completely randomized design with six treatments and five replications. The conventional nutrient solution was used as the control. The other treatments were distributed in different levels (20, 40, 60, 80 and 100%) of milk serum dilution in drinking water. Corn plants were harvested 15 days after the germination, separating biomass of shoots from biomass of the substrate with the roots. The mass of fresh and dry matter, the macro (N, P, K, Ca, Mg and S) and micronutrient (Fe, Cu, Zn and Mn) contents were evaluated, besides the elements in toxic levels (Na and Cl), in both shoots and substrate plus roots masses. Increase in milk serum concentration promoted reduction of hydroponic forage yield, increment in N, S and Zn, stability of K, reduction of Ca and Mg, and no effect on P, Fe and Cu contents in shoots. In root there was increase in P, K, Ca, Mg, S and Cu.
