Effects of Protaetia brevitarsis Larvae Manure Application on Lettuce Growth and Soil Chemical Properties

Agricultural land application of Protaetia brevitarsis larvae manure (PM) is a common process that improves soil fertility and increases crop production. The objective this study was to evaluate the effects PM on growth lettuce chemical properties. Lettuce planted in silt loam amended with three rates 0 (CF), 540 (CFP1), 1,080 (CFP2) kg 10a-1 fertilizer (20.0 N, 5.9 P2O5, 12.8 K2O) animal mixed compost (CFC). Increasing caused significant increase organic matter content yield compared CF (P < 0.05). Our findings suggest can be used as an raise crops. Effect growth.
