In situ earthworm breeding in orchards significantly improves the growth, quality and yield of papaya (Carica papaya L.).

ABSTRACT: The aim of this study was to compare the effects of four fertilizer applications-control (C), chemical fertilizer (F), compost (O), and in situ earthworm breeding (E)-on the growth, quality and yield of papaya (Carica papaya L.). In this study, 5 g plant^-1 urea (CH₄N₂O, %N = 46.3%) and 100 g plant^-1 microelement fertilizer was applied to each treatment. The fertilizer applications of these four treatments are different from each other. The results showed that the E treatment had the highest growth parameters over the whole growth period. At 127 days after transplantation, the order of plant heights from greatest to smallest was E > F > O > C, and the stem diameters were E > F > O > C, with significant differences between all treatme
