The planting material productivity and quality of the vertical layers of the poor-growing clonal stock 54-118 of the apple-tree with the 3-year growth period in the matrix and of the apple-tree with 6 pomological varieties on the stock 54-118 in thenursery in the chernozem with average supply of nitrogen, phosphorus and potassium in the middle gardening zone of Russia, were studied. The effective minimal fertilizing doses have been defined, that increases the matrix shrub prouting and the standardlayers coming-up in th matrixes: N_(180)P_(90)K_(90) or manure 20 t/ha + N_(90) by 30...40 percent.
