Development Plant Jatropha (Jatropha curcas L.) In Relation Application Of Doses Of N.

The Jatropha (Jatropha curcas L.) is an oilseed crop with great potential for biodiesel production. But there are few researches concerning the mineral nutrition of the plant. The objective of this study was to evaluate the effects of different doses of mineral nitrogen fertilization on the early growth of Jatropha in the Cerrado region. The trial was conducted at the experimental farm of the Teaching and Research of the Faculty of Engineering of Ilha Solteira - UNESP, located in Selvíria-MS. The experimental design was a randomized block design with three replications and four N rates (0, 45, 90 and 135 kg ha^-1). Conclude that up to 90 kg N ha^-1 resulted in the highest development of Jatropha plants.
