The effects of composted pineapple residue return on soilproperties and the growth and yield of pineappleAbstract:A field experiment was conducted to investigate the influence of composted pineapple residue return (CPRR) onsoil bio-chemical properties and the growth performance of next-cropped pineapple plants. The results suggestedthat CPRR markedly decreased the soil bulk density and increased the contents of available P and K. CPRRsignificantly increased the abundance of bacteria and actinomycetes, and the activities of catalase, acid phosphataseand invertase in the soil were notably heightened. Growth characteristics, including the plant height, length ofleaves and roots, leaf width, number of leaves and fresh weight of the aboveground and belowground parts weresignificantly increased by CPRR. The contents of chlorophyll, soluble sugars, and soluble protein, as well rootvigor were also markedly increased. CPRR also increased the fruit transverse and longitudinal diameters, weightand yield of next-cropped pineapple.Keywords: Pineapple, residue return, compost, soil properties, growth performance1.
