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

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.

Utilization of solid organic waste as a biofertilizer formulation for upland rice plants supports sustainable rice farming

“…[8] reported that the application of several biofertilizer wastes did not have a significantly different effect on several growth and production parameters [9]. Also showed that the application of biofertilizer waste did not have a significantly different effect on the parameters of panicle length, number of pithy grains per panicle, 1000 grain weight, percentage of pithy grain, weight of milled dry grain per clump [10]. The application of biofertilizers on upland rice plants has not seen a real effect.…”

The effect of Tofu Wastewater on Cabbage Growth and Preference of Plutella xylostella

“…Tanaman yang tumbuh dengan baik karena nutrisinya terpenuhi belum tentu bebas dari serangan hama dan penyakit tumbuhan. Limbah cair tahu pada volume 15 ml dapat meningkatkan jumlah biji padi per malai, akan tetapi tanaman padi tersebut terancam oleh gangguan hama, berupa walangsangit dan kumbang lainnya, sehingga efek peningkatan jumlah biji per malainya tidak terlalu signifikan (Hapsoh, et al, 2019).…”

Sustainable cultivation of red chili plants (Capsicum annuum L.) through a composition of NPK and biological organics fertilizers

“…The given cellulolytic bacterial consortium can also be applied in the form of biofertilizer. The biofertilizer has been applied to several plants, namely rice plants [6] and corn plants [7]. Some of the functions of biofertilizer are increasing the availability of essential macro nutrients (N, P and K) [8], producing phytohormones that can stimulate plant growth [9], NPK fertilizer can be reduced by 30%, and yields increase in horticultural crops.…”
