APLICAÇÃO DE BORO, ZINCO E NITROGÊNIO NA CULTURA DO PINHíO MANSO (Jatrophacurcas L) NA REGIíO DO SEMI-ÁRIDO POTIGUAR

Resumo

The Jatropha is native of Brazil, the family of Euforbiaceae. The objective of this research is to study the effects of boron, zinc and nitrogen on the growth and production variables of jatropha. The experiment was conducted in drainage lysimeters under protected. The statistical design was conducted in randomized block design with four replications for each treatment, were studied, plant height, stem diameter, number of leaves, leaf area. The soil substrate was used as an Ultisol non-saline, sandy loam. The irrigation was performed daily, twice daily. Thus, we examine whether or not these fertilizers caused a significant effect on all variables.
