Respons Tanaman Padi Pada Media Tanam Tanpa-Tanah Berbasis Irigasi Berselang

Urban Farm DB summary

An experiment examining the response of rice plants to non-soil planting media based on alternate wetting-drying irrigation, aimed at soilless rice cultivation as an urban farming method for subsistence food production. Conducted at a screen house in Sumberjeruk Village, Jember Regency, Indonesia, from January to May 2022, the study used a two-factor, fully randomized factorial design with three replications: husk-to-water ratio (0:1, 1:4, 1:6, and 1:8, total media volume 25 L) as the first factor, and rice variety (Inpari 46 and IR 64) as the second. The combination of a 1:6 husk:water ratio with the Inpari 46 variety had a significant effect on the number of productive tillers (25.17 stems) and grain weight per hill (34.07 g); the 1:6 ratio showed no significant difference from 1:4 in total grain number (124.21) or full grain number (83.52). The Inpari 46 variety showed the highest values for total grain number (133.07), full grain number (84.88), and 1000-seed weight (22.43 g). The study concludes that husk-and-water media at the right ratio is an ideal medium for landless rice cultivation because it can supply oxygen to the media.
