- Abstract
This paper aimed to obtain appropriate indigenous arbuscular mycorrhizal fungi types and determine the right dosage of phosphate fertilizer to increase rice yields under the System of Rice Intensification Cultivation. The research design used a factorial randomised block design with three replications. Factor I was a type of arbuscular mycorrhizal fungi (Glomus sp. 2, Glomus sp. 3, and Sclerocystis sp) on Agam river sand media with the number of spores being 120 spores per 100 grams of sand media. The dose of arbuscular mycorrhizal fungi was1.6 tons/ha or 15 g/plant. Factor II was the dose of phosphate fertilizer (P = 0%, P1 = 25%, P2 = 50%, and P3 = 75%) of the recommended dose which was applied for each treatment at these rates:: P = 0 g/plot, P1 = 20 g/plot, P2 = 40 g/plot, and P3 = 60 g/plot. The data was analsed for variance using the SAS program. The results showed that Glomus sp. 3 with 50% phosphate fertilizer efficiency had statistically significant different results (p <0.05) for plant height, number of tillers, number of panicles, number of filled grains, weight of 1000 seeds, and yield per hectare compared to the other treatments. The nutrient content of paddy fields pH, CN-ratio, total N, P available and CEC showed a statistically significant difference between the arbuscular mycorrhizal fungi types and the P fertilizer efficiency treatment. No statistically significant difference was found in the CN ratio between Glomus sp. 3 and Sclerocystis sp., but there was a statistically significant difference from Glomus sp. 2.
