Growth and production of purple eggplant (Solanum melongena L.) with application of chicken manure and liquid organic fertilizer of goat urine

It is feared that the continuous use of inorganic fertilizers at high doses could cause a decrease in soil fertility. Besides that, currently people tend to prefer organic plant products. Efforts that can be made to reduce the use of inorganic fertilizers are using liquid organic fertilizer goat urine and steps to improve soil quality require the application of manure. This study aims to determine the effect of the interaction of dosing chicken manure and the concentration of goat urine liquid organic fertilizer. This study used a factorial completely randomized design consisting of two factors, namely chicken manure with 3 dose levels of 10, 20, 30 t.ha-1 and liquid organic fertilizer (LOF) of goat urine with 3 concentration levels of 10, 20, 30%. The results showed that the interaction between chicken manure and goat urine liquid organic fertilizer did not provide an increase in all observation parameters. Applying several doses of chicken manure can increase plant height and stem diameter in purple eggplant plants with the best growth found at a dose of chicken manure 20 t.ha-1. Application of liquid organic fertilizer goat urine does not improve the entire parameter. Application of chicken manure dose of 20 t. ha-1 and concentration of 20% LOF showed the best growth and production of purple eggplant plants.
