Efeito de diferentes adubos NPK no processo de produção de mudas de eucalipto

Abstract

The present study had as its objective to evaluate the growth of seedlings of Eucalyptus camaldulensis in response to different NPK fertilizer. The study was conducted in a greenhouse, located in Ipê Nursery in the city of Goiânia-GO, between the months from December 2012 through March 2013. The seedlings were grown in commercial substrate. The experimental design was utilized randomized completely with three treatments, consisting of two NPK fertilizer, 19-06-10 Osmocote and 03-26-05 NPK conventional, and control (without fertilizer addition). For each treatment were used ten repetitions with five plants each. At 120 days after emergence were evaluated the roots length, height, stem diameter, dry mass of shoot, dry mass of root system and the reason of the dry mass of roots by dry mass of shoots. It was found that the plants respond differently to treatment and that the best results were obtained with the use of Osmocote.
