Utilization of Biochar, Compost and Phonska in Improving Corn Results on Dry Land

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.
