Abstract

Corn is the main food commodity after rice. The effort to increase corn production is the application of P fertilizer because its availability in the soil is low so that the BFA application process needs to be dissolved or acidic acidic namely tapioca wastewater and tofu liquid waste. This study aims to determine the effect of tofu and tapioca wastewater acidulation on the availability of available P, P uptake, N uptake, dry stover weight and pH on corn plants. The study was conducted at the Agricultural Technology Assessment Center (BPTP) Natar Experiment Unit, Natar District. This study uses a Split-Plot Design with the main plot is phosphate fertilizer asidulated with tapioca liquid waste and taahu liquid waste. Whereas subplots are fertilizer doses without BFA; 500 kg ha-1 (without acidic); 350 kg ha-1; 500 kg ha-1; 650 kg ha-1; 800 kg ha-1; and 950 kg ha-1. Homogeneity of variety was tested by Bartlet Test, data additivity was tested by Tukey Test. If the assumptions are met the data are analyzed differences in the mean value of treatment with the Least Significant Difference Test (LSD) at the 5% level. The results showed that the tofu liquid waste and tapioca liquid waste did not affect soil pH, P-available, P uptake, N uptake, dry weight of corn stover. In addition, the natural phosphate rock (BFA) dose of 950 kg ha-1 provides the best dose seen from the results of P uptake, N uptake, stover weight and soil pH higher than other treatments.
