Utilization of rice husk biochar and tofu dregs compost to growth and yield of sweet corn (Zea mays saccharata sturt.)

Abstract

This research aimed to obtain the appropriate dosage of rice husk biochar and tofu dreg compost for the growth and yield of corn plants. It was also to find out the interaction between biochar rice husk and tofu dreg compost on the growth and yield of corn plants. The study was conducted at the BPTP Lampineung field, Banda Aceh, from April to July 2018. The analysis used in this study was a randomized complete block design (RBD) with a factorial pattern of 3 x 3 with 3 replications. The factors studied are; a. rice husk biochar consist of 3 levels b. Tofu waste compost factor consists of 3 levels. The parameters observed included plant height, flowering age, cob length, and cob weight. The results showed that the treatment of rice husk biochar had no significant effect on plant height 15, 30, 45 DAP, the cob diameter and weight, but had a significant effect on flowering age, and had a very significant effect on plant height of 60 DAP. The treatment of various tofu dregs compost doses significantly affected plant height at 60 DAP but did not significantly affect plant height at 15, 30, 45 DAP, flowering age and cob weight. There was a very significant interaction of providing rice husk biochar and tofu compost to the length of corn cobs.
