Abstract

The main aim of this study was to investigate the nutritional value of maize samples grown under the different rates of blended fertilizer in Wolaita Zone, southern Ethiopia.

Maize samples that were grown under combined application of the two fertilizers (K and NPSB) with ratio rates of (0:0, 25:50, 50:100, 75:150 and 100:200) kg ha-1 were used as treatment. The content of nutrients from the maize was determined by flame atomic absorption spectrometry.

The mean concentration of metal in the maize sample ranged as (mg/kg): Ca (512.48-725.86), K (786.62-901.907), Mg (440.23-618.61), Fe (31.52-39.63), Zn (29.45-35.58), Pb (0.005-0.034), Cd (0.014-0.13). The study also revealed that the proximate analysis of the maize sample grown under different rates of blended fertilizer ranged as moisture (5.57-9.56%), ash (0.76- 2.29%), fat (2.83-5.95%), fiber (0.93-2.25), 6.83-11.86% and Carbohydrate (68.08-83.07%). For most metals and nutritional values, the highest content was obtained in maize samples grown under the application of 100 K and 200 NPSB kg per hectare.
