Greenhouse watermelon was grown to evaluate the effects of 'autumn mulching' (fertilizing and mulching in autumn of the previous year) on soil properties and fruit productivity. Compared with conventional 'spring mulching' (fertilizing and mulching in spring just before planting), autumn mulching tended to improve initial growth and nitrogen (N) uptake. Autumn mulching held fertilizer N and soil nitrate N in autumn of the previous year and increased soil nitrate N at the planting. In sandy clay loam (SCL) field, autumn mulching improved fruit yield and soluble solid content. In clay loam (CL) and light clay (LiC) field, autumn mulching tended to improve fruit yield and soluble solid content. Autumn mulching has the advantage that can be omitted cultivate works in springtime, in addition to the improvement of fruit productivity. From the above, it was recommended the introduction of autumn mulching in any of the field soil texture of SCL, CL and LiC.
