Protaetia brevitarsis Larvae Manure as an Organic Amendment for Cultivation of Lettuce and Red Pepper

Abstract

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 inpots 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 P2O5 10a-1, 6.5 kg K2O 10a-1, and calcium carbonate 170 for lettuce and 10.3 kg N 10a-1,11.2 kg P2O5 10a-1, 9.1 kg K2O 10a-1, calcium carbonate 170 for red pepper) and PM at three rates (0, 540, and1,080 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.
