Growth and Flavonoids Content of Black Rice (Oryza sativa L. indica) with Compost Tea of Oyster Mushroom Waste

Abstract

The flavonoid compounds in black rice (<em>Oryza sativa</em> L. <em>indica</em>) are very important for health, they serve, for instance, as antioxidants and anticancer. Giving compost tea of oyster mushroom waste (COMW) can increase plant growth and flavonoid content to black rice. This research aims to determine the effectiveness of COMW to increase the growth and flavonoid content of black rice. This experiment using completely randomized design with single factor of five COMW concentrations, four replicates respectively. The COMW was given at five different concentrations (0, 25, 35, 45 and 55%) from 25 to 45 days after planting. Parameters observed including plant height, fresh and dry weight of plants, fresh and dry weight of roots, fresh weight of grain, fresh and dry weight of total and flavonoid content. The results showed that COMW significantly increased black rice growth, the best growth was obtained by the concentration of 45% and the highest flavonoid content is by 35% concentration. No significant effect on crown height and canopy dry weight. There were significant effects on root fresh weight, shoot fresh weight, grain fresh weight, total fresh weight, root dry weight, dry weight grain, total dry weight and increased levels of flavonoids in black rice. From the research, it can be concluded that COMW increased both growth and flavonoids content of black rice.

Assessing the Effect of Rice Management System on Soil and Rice Quality Index in Girimarto, Wonogiri, Indonesia

“…Each cultivation style produces rice with a different quality index, indicating that land management changes rice quality. The organic rice field farming approach will increase soil and crop quality over time (Khoerunnisa et al, 2022). According to Mujiyo et al (2022), organic paddy fields produce better rice in Girimarto District, Wonogiri.…”

Effect of Farming Systems on Soil Carbon Sequestration and Crop Yield of Paddy (Oryza sativa L.) in Irrigated Rice Field

“…Growing and developing roots can optimally absorb water as photosynthetic material (Hodge, 2014). Increased photosynthesis can increase the results of photosynthesis in the form of acylates translocated to grain and all parts of the plant to increase biomass (Khoerunnisa et al, 2022). The amount of carbon stored in plant biomass shows carbon dioxide (CO2) absorbed from the atmosphere.…”

Effect of Compost Tea in Horticulture

“…Composting seems to be a lucrative area in agriculture biotechnology where agro-waste management is aimed at minimizing waste output, reducing environmental contamination, and boosting substrate recycling capacity [59]. The influence of compost tea from Oyster Mushroom Waste on the growth and the flavonoid content in the black rice was evaluated by Khoerunnisa et al [71]; the results displayed an increase in both the growing rate and flavonoid content depending on the treatments administered to the plants, in particular it was showed that the administration of compost tea of 45% lead to best rice growth, while the concentration of 35% lead to a best flavonoids content [71]. An example of the combined use of compost tea with other treatments is given by Lu et al [72], who investigated how hydroponically grown plants respond to UV light exposure and compost tea treatment.…”

“…Increases in production and, more generally, increases in plant biomass, as well as a physiological drive, are indicative of these impacts [7]. It is interesting to learn that compost teas can influence the final content of micro and macronutrients, thereby increasing nutritional characteristics and also increasing the content of bioactive substances, which can help maintain and improve human health [68,71]. Compost tea has shown the potential to be an ideal beneficial product in any crop system.…”
