This study assessed the use of fertilizers, vermicompost, and NPK to improve the quality of production of Moringa oleifera trees in calcareous soil conditions. It found that increasing vermicompost levels and using NPK fertilization significantly improved the yield of pods, seeds, and fixed oil, with the best results seen in the combination treatments of 10 and 20 ton ha(-1) vermicompost plus NPK control.
A shortages of soil nutrients resources and a lack of accessibility to them especially in calcareous soil are considered some of the main factors that limit plant production. In particular, the cultivation of the Moringa oleifera trees in this type of soil is of special interest given the increasing demand for every part of this tree. Several studies have focused on the production of its leaves as an herbaceous plant and not as a tree, but there has not been extensive research on its pods, seeds, and fixed oil production. In this sense, in this study, we provide an assessment of the use of fertilizers, vermicompost and NPK (as traditional minerals and as nanoparticles), in order to improve pods, seeds, and fixed oil contents, as indicators of the quality of the production of the Moringa oleifera trees in calcareous soil conditions. In this experiment, it was observed that all parameters and the yield of pods, seeds, and fixed oil of the Moringa oleifera tree were significantly improved by increasing the level of vermicompost and using NPK fertilization and combination treatments in both seasons of the study. The combination treatments of 10 and 20 ton ha(-1) vermicompost plus NPK control produced the highest percentage of oleic acid with insignificant differences between them.
