          Abstract

          Objetivou-se, com este estudo, verificar o efeito da adubação utilizando manipueira no desenvolvimento inicial do milho. O experimento foi conduzido em ambiente protegido na UFRPE, Recife, PE. Os tratamentos constaram de um arranjo fatorial 5 x 3, sendo 5 doses de manipueira equivalentes a: 0; 12,6; 25,2; 50,4 e 75,6 m³ ha-1 e 3 idades de corte: aos 20, 40 e aos 52 dias após a germinação - DAG, com quatro repetições, em delineamento inteiramente casualizado. Utilizou-se um híbrido de milho forrageiro, AG 1051, dispondo uma planta por vaso de 20 L. Foram avaliados: altura das plantas, diâmetro do colmo, número de folhas, matéria fresca e matéria seca das folhas e colmo do milho. A dose equivalente a 63 m³ ha-1 propiciou maior ganho de diâmetro de colmo, número de folhas, massa fresca e massa seca de folhas, enquanto a dose equivalente a 75,63 m³ ha-1 proporcionou incremento significativo nos demais parâmetros fenológicos avaliados. Assim, o uso da manipueira serviu como fonte de adubação para a cultura do milho cujas respostas dependeram da utilização de doses adequadas do resíduo.

          This research aimed to evaluate the effect of cassava wastewater fertilization on maize growth. The experiment was carried out under greenhouse conditions at the Federal Rural University of Pernambuco (Brazil). Treatments were assigned in a factorial arrangement 5 x 3, being 5 cassava wastewater doses: 0, 12.6, 25.2, 50.4 and 75.6 m³ ha-1 and 3 harvest ages: 20, 40, and 52 days after germination (DAG), in a completely randomized design, with four replications. A hybrid of forage maize (AG 1051) was used, keeping one plant in a 20 L pot. The variables evaluated were: plant height, stalk diameter, number of leaves, dry and fresh matter of leaves and stalks. The dose equivalent to 63 m³ ha-1 provided the highest gain in stalk diameter, number of leaves, dry and fresh matter of leaves; while the dose equivalent to 75.63 m³ ha-1 provided significant increase in the other evaluated phenological parameters. Cassava wastewater presented as a useful fertilization source for maize crop, however responses depended on utilization of appropriated cassava wastewater doses.
