<![CDATA[This study aims to investigate the effect of biochar and phonska as well as its interaction on the growth and yield of corn crops. This experiment used a randomized block design (RBD), a factorial pattern with 2 factors. The first factor was the biochar dose consisting of 4 levels, ie: without biochar, 5 t ha-1, 10 t ha-1, and 15 t ha-1. The second factor was the dose of phonska fertilizer consisting of 2 levels: without phonska and 300 kg ha-1. The results showed that the dose of biochar 10 t ha-1 gave the highest dry weight of seed per hectare of 8.12 tons, an increase of 32.77% compared with without biochar of 6.12 tons. The treatment of phonska fertilizer dosage of 300 kg ha-1 gave the highest dry weight of seed per hectare of 8.07 tons and the increase of 26.68% compared with without phonska of 6.37 tons. Based on a result of regression analysis test obtained optimum dose 10.44 t ha-1 with a dry weight of seed per ha maximum 7.90 ton. Keywords: charcoal, bamboo biochar, NPK phonska, corn]]>
