Crescimento inicial de Moringa oleifera em substrato arenoso com adição de vermicomposto em duas luminosidades

Initial growth of Moringa oleifera in the sandy substrate with the addition of vermicompost in two luminosities

Abstract

Objectives: evaluate the formation of seedlings of Moringa oleifera during 150 days, in oleifera in sandy substrate with addition of vermicompost in two luminosities. Method: experiment was conducted in an experimental design of randomized blocks with four treatments: T1) typic quartzipsamment 60% + 40% vermicompost; T2) typic quartzipsamment 80% + 20% vermicompost; and, T3) 100% typic quartzipsamment, under two light intensities (in full sun and 70% of solar radiation). The sample collections were 30, 60, 75, 90 and 105 days after transplanting and determined the height, dry weight of the aerial part, dry weight of the root, total dry weight, diameter of the stem and Dickson Quality Index (IQD). The data were visualized through a regression curve and submitted to analysis of variance (Tukey test at 5%). Results: the substrates with a higher concentration of organic matter are more suitable for the seedlings and the species has growth plasticity, in relation to luminosity. Conclusions: the IQD demonstrated that plants kept in greater light and amount of organic matter are more robust and that the T1 treatment was the most effective for the production of quality seedlings.
