CLOD STRUCTURE AND THE QUALITY OF MORINGA SEEDLINGS (Moringa oleifera LAM.) GROWN IN COMMERCIAL SUBSTRATE AND IN ORGANIC COMPOSTS

ABSTRACT The cultivation of tuberous-root species such as Moringa oleifera Lam. (moringa) requires well-dimensioned containers and the use of appropriate substrates, since seedlings will be removed from the container before their planting. Sugarcane bagasse, urban waste compost (compost), and vermic...

Zusammenfassung:ABSTRACT The cultivation of tuberous-root species such as Moringa oleifera Lam. (moringa) requires well-dimensioned containers and the use of appropriate substrates, since seedlings will be removed from the container before their planting. Sugarcane bagasse, urban waste compost (compost), and vermicompost are promising wastes for substrate composition. The present study aims to assess the quality of moringa grown in substrate produced from sugarcane bagasse associated with compost or vermicompost in different-volume tubes. The study followed a randomized blocks design, at 2x7 factorial arrangement, namely: tubes’ volumes (50 and 240 mL) x seven substrates (commercial substrate; sugarcane bagasse associated with urban waste compost at three different ratios (1:3; 1:1 and 3:1) and sugarcane bagasse associated with vermicompost at ratios 1:3; 1:1 and 3:1). In conclusion, the 240 mL container was the most appropriate one for moringa seedlings’ production. Substrates presenting higher organic compost ratios led to greater shoot and tuberous root growth and to greater nitrogen-use accumulation and efficiency, which was equivalent to that of the commercial substrate. Higher sugarcane bagasse rates in substrate composition made it easier to remove the seedlings from the tubes and led to better physical quality of the clod after seedling removal from the tubes. RESUMO O cultivo de mudas de espécies com raízes tuberosas como Moringa oleifera Lam. (moringa), requer recipientes bem dimensionados e o uso de substratos adequados, considerando que a muda será retirada do recipiente antes do plantio. Bagaço de cana, composto de lixo urbano (composto) e vermicomposto são resíduos promissores na composição de substratos. O trabalho teve como objetivo avaliar a qualidade das mudas de moringa cultivadas em substratos produzidos a partir de bagaço de cana associado com composto ou vermicomposto em tubetes de diferentes volumes. O delineamento experimental foi em blocos casualizados, em esquema fatorial 2x7, sendo: volumes dos tubetes (50 e 240 mL) x sete substratos (substrato comercial; bagaço de cana misturado a composto de lixo urbano em tres diferentes proporções (1:3; 1:1 e 3:1) e bagaço de cana misturado a vermicomposto nas proporções 1:3; 1:1 e 3:1). Concluiu-se que o recipiente de 240 mL foi o mais adequado para a produção de mudas de moringa. Substratos com maiores proporções de composto orgânico resultaram em maior crescimento da parte aérea e das raízes tuberosas, co
