Application of biofertilizer consortium formulation of cellulolytic bacteria based on organic liquid waste on yield of upland rice (Oryza sativa L.)

Abstract

Abstract Rice production in Riau Province is lower than demand. One of the efforts made is the use of organic fertilizer based on organic liquid waste, in addition to reducing the use of inorganic fertilizers. The method that can be applied to support rice yield is the use of cellulolytic bacterial consortium applications. This study aimed to finding out the formulation and dose of biological fertilizer based on cellulolytic bacteria based on the organic liquid waste that was good for growth and yield of upland rice. This research used a Completely Randomized Design which consisted of 12 treatments, namely of biofertilizer of rice washing water, biofertilizer of coconut water, biofertilizer of wastewater tofu, biofertilizer of palm oil mill with doses 5, 10, 15 ml. The result showed that all biofertilizers based on organic wastewater cellulolytic consortium could provide varied results on all parameters of observation so that all biological fertilizers could be applied to upland rice plants with the use of inorganic fertilizers at half the recommended dose. Biofertilizers from rice washing water with a dose of 10 ml gave a good response to the growth and yield of upland rice compared with other treatments.
