fertilizer efficiency, straw compost
Sustainability or food security (rice) is highly dependent on the quality and health of soil and water availability. Current conditions indicate that about 70% of paddy fields in Indonesia has been experiencing severe degradation of land and can be categorized as an illness (sick soils), therefore, efforts to restore health and increase the productivity of paddy soil in a sustainable manner can be done by integrating fertilizer-based integrated management organic and biological fertilizers (bio- fertilizers) with SOBARI (System of Organic Based Aerobic Rice Intensification) technology. The experiment was conducted from March to August 2011 in the fields experiment Faculty of Agriculture Padjadjaran University, Ciparay The aims were to test the use of straw compost + bio-fertilizer for efficiency inorganic fertilizer (N, P, K) and to increase rice production by SOBARI technology Experiment was using a split plot design. The main plot consisted of 8 standard combination of organic fertilizer (compost straw 0; 2.5; 5.0; and 7.5 t/ ha, with no biological fertilizers and biological fertilizers 400 g/ha. The sub plots consisted of 5 inorganic fertilizer levels on N, P, and K (100; 90; 80; 70; and 60% of recommended dosage). The data obsereved were analyzed by ANOVA (analysis of variance) and Duncan’s Multiple Range Test (DMRT) at α 5%. The parameters observed were plant height, number of tillers, productive tillers, and rice production, There was an interaction occur between the provision of straw compost + bio-fertilizer to the yield per plot, Dosage of 5.0 t/ha of compost straw 400 g/ha biological fortilizer by accompanied N, P, K 80% of the recommended, showed the highest yields and increase the yield of 13.3% compared to controls is 7,29 kg/plot (6,654 t/ha) and gained efficiency fertilizer N, P, K 20% of the recommendation.
