Summary
Objetivou-se, neste estudo, avaliar o desenvolvimento vegetativo e o acúmulo de macronutrientes em plantas de milho submetidas às doses de manipueira. O experimento foi conduzido em ambiente protegido no período de março a maio de 2011. O delineamento experimental foi inteiramente casualizado em esquema fatorial 2 (tipos de solo: franco-arenoso e franco-argiloso) × 4 (doses de manipueira: 0; 11,2; 22,4 e 44,8 m3 ha-1), com oito repetições. As variáveis analisadas foram: altura das plantas, diâmetro de colmos, número de folhas, matéria fresca e matéria seca da parte aérea das plantas e teores de N, P, K, Ca e Mg no tecido foliar. O aumento das doses de manipueira elevou o conteúdo de massa fresca, o teor de nitrogênio e potássio da parte aérea das plantas, mas diminuiu a altura das plantas e o teor de magnésio na parte aérea das plantas. Os acréscimos de matéria seca e de cálcio na parte aérea das plantas foram maiores no solo franco-arenoso.
Summary translation
The aim of this study was to evaluate the growth and nutrient accumulation in maize plants fertilized with cassava wastewater. The experiment was carried out under greenhouse from March to May 2011. The experimental design was completely randomized, in a factorial 2 (soil types: sandy loam and clay loam) × 4 (doses of cassava wastewater: 0; 11.2; 22.4 and 44.8 m3 ha-1) arrangement, with eight replications. The variables analysed consisted of: plant height, stem diameter, number of leaves, fresh and dry mass of shoot and N, P, K, Ca and Mg content in leaf tissue. The use of cassava wastewater contributed to reduce plant height and increase both fresh mass of shoots and potassium content in leaf tissue. Increase in shoot fresh was higher in sandy loam soil.
