This study was conducted to investigate the application effects of dried food waste powder (FWP) and mixtures of FWP and organic fertilizer (MFOs) on the growth of lettuce and Chinese cabbage. The physicochemical properties of FWP and MFOs were analyzed. As FWPs containing 3.11% NaCl was applied at 250 kg, 500 kg and 1,000 kg per 10a, growth factors of lettuce and Chinese cabbage, such as a number of leaf, leaf length, leaf width, and dry weight were decreased than those of control appling organic fertilizer. The higher the FWP ratio in the MFOs, the lower the concentrations of N and P₂O₅ in the MFOs, while the higher the concentration of NaCl. As compared to dry weight of control after treating MFOs, lettuce were not significant in MFOs treatments containing 10~30% FWP, and Chinese cabbage in MFOs treatment containing 10% FWP.

This study was conducted to investigate effects of mixture with dried food waste powder (FWP) and mixed organic fertilizer (MOF) on growth of pakchoi. As compared with non-fertilizer treatment (NF) or control (MOF treatment), growth of pakchoi in FWP treatments (2,500 kg/ha, 5,000 kg/ha, 10,000 kg/ha) was inhibited by salt (NaCl) content in the FWP. In comparison with control, mixtures of MOF and FWP (FWP10, FWP20, and FWP30 treatment) were not significantly different, and their salt content correlated with pakchoi growth factors negatively (P<0.05). Applied of FWP10, (FWP10: 2,500 kg/ha, 2FWP10: 5,000 kg/ha, 3FWP10: 7,500 kg/ha, 4FWP10: 10,000 kg/ha), growth factors of FWP10, 2FWP10 and 3FWP10 treatment were not significantly different than those of chemical fertilizer treatment, and of 4FWP10 decreased. Correlation coefficient between NaCl supply by FWP10 application and growth factor was negative (P<0.01). These results indicated that FWP was used as another source of organic fertilizer, and the organic fertilizers blending with FWP inhibited a pakchoi growth by increase of salt content containing in the them or of salt supplying amount after their application.

This study was conducted to evaluate the properties of mixtures of mixed organic fertilizer (MOF) and various organic sources such as livestock manure compost (LMC), dried compost of poultry manure (CPM), dried food waste powder (FWP) and amino acid by-product fertilizer (ABF) and their influences on growth of lettuce and Chinese cabbage. The content of N, P2O5 and K2O of mixture of MOF, LMC and FWP (MLF) was 3.6~3.9%, 2.1~2.2% and 1.3~1.4%, respectively. Lettuce dry weight of MLF3 treatment blending with MOF (60%), LMC (10%) and FWP (30%) was increased by about 29% than that of MOF. The content of N, P2O5 and K2O of mixture of MOF, CPM, FWP and ABF (MCFA) was 4.5~4.7%, 1.7~1.9% and 1.3~1.4%, respectively. Compared to MOF, growth factors of lettuce and Chinese cabbage in the MCFA treatments were not significantly deferent. These results indicated that MLFs and MCFAs, the mixtures of respectively organic sources and MOF, could be applied as orgnic fertilizer in the cultivation of lettuce and Chinese cabbage, and were expected that LMC and ABF might be used as another sources of organic fertilizer.
