The Effect of Neem Leaves Powder (Azadiractha Indica A. Juss) and Storage Time to Rejected Corn Quality

Abstract

This research has aimed to determine the level of neem leaves powder (Azadirachta indica A. Juss) and the optimal storage time of rejected corn to decrease aflatoxin content, percentage of water content, and percentage of moldy seeds. This research uses a completely randomized experimental design (CRD) 6 x 4 factorial with three replications. Where factor A is the level of neem leaves powder (0, 0.5%, 1%, 1.5%, 2%, 2.5%) and factor B is the storage time (2, 4, 6 and 8 weeks). The analysis showed that there was no interaction (P> 0.05) between factor A and factor B to the content of aflatoxin, percentage of water content and percentage of moldy seeds, but respectively for factor A and factor B had a very significant effect (P <0.01 ) against aflatoxin content and percentage of water content. For a percentage of moldy seed, only factor B had a very significant effect (P <0.01). The results of the study can be concluding that the selected treatment found on neem leaves powder level of 1% with four weeks of storage time (A3B2). In this condition, a decrease in the aflatoxin content of rejected corn from 170 ppb to 53 ppb (a decrease of 68.43%) with a water content of 14.47% and 0% moldy seeds.
