The present study was conducted to evaluate fertigation effects of balanced manure nutrients from combined fertilizers on the growth of eggplant (Solanum melongena L.) and soil chemical properties in greenhouse cultivation. There are 4 treatments for fertigation; animal liquid manure (LM), LM supplemented with chemical ferilizer (LM+CF) to make nutrient-balanced ferilizer, LM supplemented with chemical ferilizer and phosphorus acid (LM+CF+PA), and conventional chemical fertilzer (CCF). Fruit lenth, width, and weight for LM treatment were significantly lower than LM+CF, LM+CF+PA, and CCF treatments. There was no significant differences in fruit length, width, and weight among LM+CF, LM+CF+PA, and CCF treatments. The yield of eggplants per plant for LM treatment (26.2 kg) was decreased by 6% compared to CCF treatment (27.9 kg). The growth and yield of eggplants were not significant different among CCF, LM+CF, and LM+CF+PA treatments. The marketable yield for LM treatment was lowest among 4 treatments and that for LM+CF+PA treatment (26.6 kg) was increased by 8% compared to CCF treatment (24.1 kg). The chemical properties of the soil for CCF treatment, in general, tended to be higher compared to the other treatments. In conclusion, the present study demonstrates that the application of balanced liquid manure combined with mineral fertilizer to soil is considered as a good management practices because it improves, eggplant quality and soil properties.
