Crescimento de mudas de Moringa (Moringa oleifera lam.) submetidas a doses crescentes de composto orgânico

Abstract

The growing demand for good quality seedlings with vigorous characteristics, in a short period of production, requires the adaption of faster and sustainable alternatives, helping to reduce environmental impacts. it is necessary to use alternative fertilizers, which help reduce waste generated by the population and are more accessible to small producers, such as organic fertilizers. In view of the above, the objective of this work was to evaluate the growth of Moringa oleifera LAM seedlings. submitted to increasing doses of organic compost. The experiment was conducted in a greenhouse at the Jundiaí Agricultural School (EAJ) from May to June 2018. The experimental design was a randomized block design with six treatments and four replicates, totaling 24 experimental units. The organic compost was applied at the doses of 0, 420, 850, 1270, 1690 and 1900 g pot-1, corresponding respectively to 0, 4, 8, 12, 16 and 18% volume of compost per volume of soil (v/v). The variables evaluated were: plant height (cm), stem diameter (mm), fresh and dry leaf mass, fresh and dry mass of the stem (g), fresh and dry mass of the main root (g), main root length (cm), and leaf area (cm²). The dose of 420 g.vaso-1 presented the best average values for most variables, except fresh stem mass, main root length, and fresh and dry mass of the main root.
