Application of Dosage Combination of Evagrow Biofertilizer and Chemical Fertilizer on Soil Characteristics, Growth and Yield of Rice

Research the effectt of Evagrow biofertilizer and chemical fertilizers on soil properties, growth and yield of rice has been carried out in the glasshouse Faculty of Agriculture Udayana University in the form of factorial experiment with a Randomized Block Design (RBD). The first is Evagrow bifertilizer factor in 3 level E0 (without biofertilizers), E1 (5 g biofertilizer. per litre) E2 (10 grams biofertilizer per litre. The second factor is chemical fertilizer consists of 3 levels: K0 (without chemical fertilizers), K1 (150 kg Urea/ha + 75 kg SP36/ha + 37.5 kg KCl/ha), K2 (300 kg Urea/ha + 150 kg SP36/ha + 75 kg KCl/ha). The results showed that chemical fertilizers, give a signifant effect to the very significant effectl against most of the rice growth and yield parameters. The application of chemical fertilizers K1 and K2 each can increase the yield of dry grain harvest amounted to respectively 52.87% and 102.54% compared to controls. While the application of Evagrow bifertilizer has no effect against the real parameters of growth and yield of rice. The interaction between the application of chemical fertilizers and Evagrow biofertilizer was not found. Similarly to some of the soil properties, the granting of biological fertilizer and chemical fertilizer does not show the real influence on most of the soil properties, except on levels of salt. Key word: rice, inorganic fertilizer, evagrow biofertilizer
