USO DE DIFERENTES SUBSTRATOS E DO SUPERFOSFATO SIMPLES NA PRODUÇÃO DE MUDAS DE NESPEREIRA (Eriobotrya japonica Lind)

Abstract

It was carried out, in the nursery area located at Campus of Federal University of Lavras (UFLA) Minas Gerais, an experiment aiming to evaluate different doses of simple super phosphate and two substrates in plant production of loquat tree. It was tested four doses of simple super phosphate (0; 2.5; 5; 10 kg m-3 of substrate) and two substrates: A (organic compost + sand + soil in 1:1:3 volume proportion) and B ( Plantmax + sand + soil 1:1:3 volume proportion) A randomized block design was used with a 4 x 2 factorial scheme, with four replications and four plants per plot. The following characteristics were evaluated: high of plants (cm); length of root (cm); number of leaves/plant, dry matter of above ground part, roots and total (g/plant). The results showed that for seedlings of loquat tree, it is recommended to mix to substrate the super phosphate fertilizer in doses until 6 kg m-3. Between the substrates, the one the showed more viable was the substrate A (organic compost + sand + soil in 1:1:3 volume proportions).
