Abstract

COELHO, Ruimário Inácio; CARVALHO, Almy Júnior Cordeiro de; THIEBAUT, Jose Tarcisio Lima  and  SOUZA, Matheus Fonseca de. Leaf nutrient contents on ´smooth cayenne´ planting material as response to fertilization. Rev. de Ciências Agrárias [online]. 2010, vol.33, n.2, pp.173-179. ISSN 0871-018X.

‘Smooth Cayenne’ planting material obtained through stem sectioning were trea-ted with foliar  fertilization with different concentrations of urea, KCl, in weekly pulverizations, and H3BO4, totalizing twenty-six for urea and KCL pulverizations and four for H3BO3, which was applied monthly The treatments were began nine weeks after planting thestem sections. The experimental scheme was a fractionated factorial (1/5)53 with three types of fertilizers (urea, KCl and H3BO3) and five concentrations in a total of 25 treatments. There were 50 sections per plot. Treatments were a combination of concentrations in g L-1: 0, 2.5, 5.0, 7.5 and 10 of urea and KCl, and 0, 0.5, 1.0, 1.5 and 2,0 of  H3BO3.  Sample analyses of ‘D’ leaves showed urea and H3BO3 effect on  S, Cl and B leaf contents whereas  KCL affected leaf K and Cl contents. Urea did not affect N leaf content, however it strongly influenced N content in planting material.

Keywords : Ananas comosus; foliar fertilization; pineapple; propagation.
