Abstract:
Utilization of legume cover crop (LCC) as insitu-green fertilizer is an alternatives for carbon (C) storage in soil and nitrogen (N) source for organic farming. However, its usages were not optimum due to lack of synchronization state (un-matching point between nutrient release and plant need). This research aim to describe model of synchronization point of Maize (Zea mays) using green feilizer from LCC. A pot experiment had conducted using factorial block randomized design (RBD) with two factors: 1) types of LCC residues (Crotolaria usaramoensis and Phaseolus lunatus); and 2) application time (10, 20 and 30 days before planting-DBP). The results showed that, there was no difference between types of LCC, mean while application time (10 DBP) was significant (p<0.05) difference for synchronization state of N during vegetative phase (60 days) than others.
