DOSES DE LITHOTHAMNIUM E DIFERENTES SUBSTRATOS NA PRODUÇÃO DE MUDAS DE MARACUJAZEIRO 'DOCE'

Abstract

The aim of this work was to verify the effects of Lithothamnium (Concinal Fertilizador®) in different substrates. The experiment was carried out at plant formation area at Federal University of Lavras orchard, testing the following doses of Lithothamnium: 0; 2; 4; 6; and 8 kg m-3 in two compositions of substrates: A (organic compost + sand + soil at 1:1:3 volume proportion) and B (Plantmax + sand + soil at 1:1:3 volume proportion). The randomized blocks was 5 x 2, with 4 repetititons, and 5 plants for plot. The following characteristics had been evaluated: length of the aerial part (CPA), length of the system to radicular (CR), leaf number (NF), dry substance of the aerial part (MSPA) and dry substance of the root (MSR). For seedling production of passion fruit, Lithothanium was good option for growth of passion fruit seedling, and the substrate B promoted best plants.
