Agricultural land application of Protaetia brevitarsis larvae manure (PM) is a common process that improves soil fertility and increases crop production. The objective of this study was to evaluate the effects of PM on the growth of lettuce and soil chemical properties. Lettuce was planted in silt loam soil amended with three rates of PM 0 (CF), 540 (CFP1), and 1,080 (CFP2) kg 10a -1 with chemical fertilizer (20.0 kg 10a -1 N, 5.9 kg 10a -1 P 2 O 5 , and 12.8 kg 10a -1 K 2 O) and animal mixed compost 540 kg 10a -1 with chemical fertilizer (CFC). Increasing rates of PM caused a significant increase in soil organic matter content and yield of lettuce compared to CF (P < 0.05). Our findings suggest that Protaetia brevitarsis larvae manure can be used as an organic fertilizer to raise crops.

This study was conducted to investigate the effects of the application of Protaetia brevitarsis larvae manure (PM) on the growth lettuce (Lactuca sativa L.) and red pepper (Capsicum annuum L.). Crops were planted in pots containing silt loam soils and cultivated with the basal application of chemical fertilizer at a standard rate (10.0 kg N 10a -1 , 5.9 kg P 2 O 5 10a -1 , 6.5 kg K 2 O 10a -1 , and calcium carbonate 170 for lettuce and 10.3 kg N 10a -1 , 11.2 kg P 2 O 5 10a -1 , 9.1 kg K 2 O 10a -1 , calcium carbonate 170 for red pepper) and PM at three rates (0, 540, and 1,080 kg) in pots (1/5000a). The growth of lettuce and red pepper increased with increased application of PM. Our results suggest that PM can be used as organic amendment for crop cultivation.
