Efecto de la fertirrigación con n y k en el crecimiento de la palma de coco enano Verde de jiqui

The coconut palm crop has increased with the use of the fertigation technique in Brazil in the last years. The objective of this work was to evaluate the influence of N and K rates via fertigation, on vegetative growth of three year old palms, cultivated in the littoral region of the Ceará State, Brazil, with tropical rainy climate. The study was conducted in a sandy soil using the variety of green dwarfed Jiqui coconut palm. The experimental design was a randomized complete block, with 10 treatments, including five nitrogen and five of potassium rates, according to the model of the experimental matrix Plan Puebla III. The nitrogen and potassiun applications via fertigation influenced significantly the plant height, stem perimeter, and the number of leaves and folioles. © 2009 Universidad Centroccidental Lisandro Alvarado (UCLA).
