Changes in soil fertility with vermicompost, eco farm, and mycorrhiza on two rice varieties under drought stress conditions

Abstract Fulfillment of food needs is a shared global responsibility. This is to maintain the calorie needs of the population in all countries. Organic farming is an option to support the sustainability of world food production. Research on the use of vermicompost, eco farms, and mycorrhiza is part of an effort to overcome the impact of drought that has hit most of the world’s agricultural land. The study used 3x2x2 split-split plot design with the main factors of soil amendments consisting of vermicompost, eco farm, and mycorrhiza, with drought treatment being tried on two rice varieties, IPB 9G and Inpago 12. The results showed changes in soil pH, ECe, NPK content, and SPAD values. The changes that occurred varied greatly, indicating specific responses to the three soil amendments, the level of drought, and the physiology of rice roots. The study’s results can be used as approaches to overcome the decline in soil fertility in increasing rice yields.
