Adubação em "torrão paulista" de Eucalyptus Saligna SM

Abstract

This paper deals with a3 X 3 X 3 X 2 factorial experiment with N, P, K, manure, applied to seedlings of Eucalyptus saligna Sm., planted in pots of the type known as "torrão paulista". Results were statistically significant for N, P and manure. The average heights of plants, 3½ months after planting in the pots were, in centimeters, the following: N0 42,4 ± 1,5 P0 56,4 ± 1,5 E0 54,9 ± 1,2 N1 62,8 ± 1,5 P1 58,4 ± 1,5 E1 64,0 ± 1,2 N2 73,2 ± 1,5 P2 63,6 ± 1,5 The averages corresponding to some more interesting treatment combinations are given below: N0PoK0Eo 41,3 ± 6,2 N2P2K0E1 83,0 ± 6,2 N2P0K0E0 59,6 ± 6,2 N2P2K2E1 87,4 ± 6,2 N2P2K0E0 64,0 ± 6,2
