This study aims to determine the effect of cow manure phosphorus uptake on sweet corn ( Zea mays L. saccharata) in Entisols Sidera. This study used a Randomized Block Design (RBD) method with 6 levels of treatment and was repeated 4 times so as to obtain 24 experimental units, 6 levels of the treatment dosage include : Control (Without administration of cow manure); Cow manure with a dose of 5 tons ha - 1 ; Cow manure with a dose of 10 tons ha -1 ; Cow manure with a dose of 15 tons ha -1 ; Cow manure with a dose of 20 tons ha -1 ; Cow manure with a dose of 25 tons ha -1 . The results showed that administration of cow manure with a dose of 25 tons ha -1 could increase C-Organic by 3.54% , P-Total by 51.37 mg / 100g , P-Available by 18.17 ppm , P concentration of plant tissue 0.094% and phosphorus uptake on sweet corn plant of 0.020%.
