UTILIZATION OF VERMICOMPOST AND BLACK SOLDIER FLY FRASS IN ORGANIC RICE CULTIVATION
Main Article Content
Abstract
This study aimed to compare the effects of chemical and organic fertilizers on the growth and yield components of Oryza sativa L. cv. RD43. The experiment was conducted using a randomized complete block design (RCBD) with five treatments: no fertilizer, vermicompost from different rearing substrates, and Black Soldier Fly (BSF) frass. The results showed that BSF frass significantly enhanced plant height (112.12 cm), chlorophyll content (maximum 36.27 SPAD units), and produced the highest number of tillers (16.25), panicles (14.00), and grains per panicle (141.06). However, this treatment resulted in a lower percentage of filled grains (63.37 %) and a higher percentage of unfilled grains (36.62 %). In contrast, the vermicompost treatment yielded fewer grains per panicle but had the highest percentage of filled grains (83.59 %) and a greater 100-grain weight (2.37 g), indicating a more balanced and efficient grain development process. In conclusion, organic fertilizers, particularly BSF frass, demonstrate potential in enhancing vegetative growth and structural yield components; however, nutrient management during the grain-filling stage may be necessary to optimize grain quality.
