Daftar Isi:
- The average productivity of upland rice in Indonesia is around 4.4 tons per ha. This productivity is classified as very low when compared to the potential yield which can reach 8.5 tons per ha. The utilization of synthetic zeolite as soil amendment and liquid organic fertilizer (LOF) is one of the technologies that can be applied to increase the growth and yield of upland rice. This study was carried out by factorial experiment consisting of 2 factors. The first factor is the application of synthetic zeolite which consists of 4 levels (0, 100, 150, and 200 kg per ha) and the second factor is the application of LOF which consists of 3 levels (0, 200, and 400 ml per clump), and each combination was repeated 3 times. The results showed that the application of synthetic zeolite and catfish LOF at each dose had no significant effect on plant height, maximum number of tillers and productive tillers, panicle exit age, harvest age, and weight of milled dry grain per clump. The interaction of synthetic zeolite at a dose of 100 kg per ha with catfish LOF at a dose of 400 ml per clump increased the number of pithy grain per panicle by 70%, the weight of milled dry grain per clump by 68%, and the harvest index 37.5% significantly compared to no treatment.
