Abstract

This study aims to obtain the best dose or optimum dose of biochar, compost, and phonska in improving the yield of corn in the dry land. This experiment used a randomized block design (RBD) 3 replication with a nested experiment, where the dose factor was nested in each type of fertilizer. The treatment factor consisted of 3 types of fertilizer (J), namely[Inserted: the ]: biochar (B), compost (K), and phonska (P) with 3 fertilizer doses (D) and a control as a comparison. The results showed that the dosage of [Inserted: a]biochar 10 t ha-1 could increase the highest total oven dry weight of 509.31 g, which increased by 23.95% when compared with without biochar of 410.90 g. Composting doses of 20 t ha-1 can yield the highest total dry weight of the oven of 525.05 g, an increase of 27.78% when compared with no treatment of 410.90 g. Phonska dosage of 300 kg ha-1 can give the highest yield of the dry weight of the highest total plant oven of 563,91 g, increasing by 37,24% when compared with without treatment equal to 410,90 g. The results of this study obtained the optimum dose of [Inserted: the ]biochar 10.52 t ha-1, compost 20,22 t ha-1, and phonska 313,37 kg ha-1 that can be used to improve a yield of the corn plant in the dry land.
