Abstract

The average productivity of upland rice in Indonesia is around 4.4 tons per ha, significantly lower than its potential yield of 8.5 Mg per ha. The utilization of synthetic zeolite as a 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 with 2 factors: synthetic zeolite application at 4 levels (0, 100, 150, and 200 kg per ha), and catfish LOF application at 3 levels (0, 200, and 400 ml per clump), and each combina- tion was repeated three times. The results showed that applying 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 grains per panicle by 70%, the weight of milled dry grain per clump by 68%, and the harvest index 37.5% significantly compared to control (no treatment).

Abstract

The low productivity of upland rice on Podzolic (Ultisol) soil is caused by various constraints including low pH, the content of macronutrient N, P, K, Ca and Mg, BS and CEC were low, solubility and high Al saturation, high P fixation, delicate to erosion and water availability were low. Applied of zeolite synthesized from coal fly ash with high CEC is expected to overcome these constraints. The high negative charge on zeolite contributes to increasing soil absorption of nutrients provided or dissolved from soil minerals and decomposition of organic matter. The study was conducted experimentally using a completely randomized design, zeolite fly ash as the treatment consisting of 6 levels (0, 100, 150, 200, 250 and 300 kg ha-1) each repeated 3 times. The results showed that the application of zeolite fly ash dose 100-300 kg.ha-1 tends increased the plant height, filled grain number per panicle, the percentage of filled grain and 1000 grain weight compared without zeolite application and the highest increased showed in the number of maximum tillers and productive tillers and weight of milled dry grain per clump was obtained at a dose of 200 kg.ha-1 compared without zeolite is 45, 107 and 106% respectively.
