- Abstract
The aim of this study was to evaluate the physiological parameters of the hybrid corn AG 1051 grown in a protected environment in soil fertilized with human urine and treated cassava wastewater. The experimental design was completely randomized with fourteen treatments and four replications, thus totaling 56 experimental units. The treatments were as follows: T1 (NPK), T2 (470 mL), T3 (670 mL), T4 (870 mL), T5 (1070 ml), T6 (1270 ml), T7 (1470 mL), T8 (F - NPK), T9 (F - 470 ml), T10 (F - 670 ml), T11 (F - 870 ml), T12 (F - 1070 ml), T13 (F - 1270) and T14 (F - 1470). The volume applied is the combination of human urine + cassava wastewater treated as foundation fertilization and fertigation (F). The production of chlorophylls A, B, total and carotenoids, SPAD and °Brix were evaluated. The T1 treatment promoted an increase of 43.94% in the SPAD index in relation to T2. Height increases in total soluble solids concentration were obtained for T1, T5, T7 and T8. The T13 treatment promoted maximum values of chlorophyll A and total of 3843.703 and 5479.152 µgg-1 respectively. For T14 the maximum yields were for the variables chlorophyll B and carotenoids (2805.197 and 333440.042 µgg-1). Treatments positively influence all physiological variables.
