Liquid organic fertilizer effectiveness test and the combination with chemical fertilizer on maize to increase yield in dry land

Abstract

Abstract The aim of the research was to examine the effectiveness of Liquid Organic Fertilizer (LOF) combination with chemical fertilizer on maize to increase yield in dry land. The research was conducted from May to October 2018 in Kediri Regency. The research used a RBD with seven treatments and four replications, namely were: A = Control; B = RRCF; C = 6 L LOF ha-1; D = ¾ RRCF + 3 L LOF ha-1; E = ¾ RRCF + 6 L LOF ha-1; F = RRCF + 3 L LOF ha-1, and G = RRCF + 6 L LOF ha-1. The data were analyzed by ANOVA using SPSS 2.2 software, and result further tested using DMRT at 5% significance level. The addition 6 L LOF ha-1 with RRCF (G), seeds yield of maize reached 8.44 t.ha-1 it yield was higher than the treatment of 3 L LOF ha-1 with RRCF (F) which was 7.85 t.ha-1. The calculation of the RAE value showed that treatment G obtained the highest RAE value of 139.46%, while the second highest RAE value was obtained for treatment F of 119.73%.
