Abstract
This study aims to determine the effect of aerobic rice system, either with or without organic fertilization and intercropping with soybean, on growth and yield of two genotypes of red rice. The experiment was arranged in Completely Randomized Design testing three treatment factors: rice cultivation techniques (T1= conventional, T2= aerobic rice intercropped with soybean, T3= aerobic rice without intercropping); organic fertilization (B0= without, B1= with organic fertilization using “Bokashi”); red rice genotypes (V1= Inpago Unram 1, V2= Amp-G9), with three replications. The results indicated that the interaction was significant only between cultivation techniques and organic fertilization on plant height at 8 weeks after planting (WAP) and leaf number at 5 WAP. However, rice cultivation techniques significantly affected almost all observation variables, whereas organic fertilization significantly affected only plant height at 8 WAP. In relation to yield, the aerobic rice system without intercropping with soybean (T3) yielded significantly the highest rice grain weight per clump (40.32 g) compared with the aerobic system intercropped with soybean (32.68 g) and the conventional technique (22.67 g). Based on "Best Subsets Regression", growth rate of tiller number (which was highest in T3), contributed the highest to rice grain yield (55.8%), and panicle length (59.6%).
