Crescimento e produção de coqueiro Anão verde fertigado com nitrogênio e potássio

Abstract: Tal como ocorre em outras culturas, no cultivo de coco irrigado a utilização da técnica da fertigação também tende a aumentar. Objetivou-se com este trabalho estudar os efeitos de doses de N e K2O via fertigação no desenvolvimento vegetativo e na produção do coqueiro Anão verde. O ensaio foi conduzido no período de abril de 2002 a março de 2004, em campo experimental da Empresa de Pesquisa Agropecuária do Rio Grande do Norte - EMPARN, em Parnamirim, RN. O delineamento estatístico adotado foi em blocos inteiram… Show more

“…Considering that urea was applied in the same amount in all treatments, possibly the inhibition of nitrogen absorption by plants results from the increase in soil Clconcentration that accompanied the GCSL doses, in addition to the high C/N ratio of GCSL. Crisóstomo and Aragão (2011) determined that, among the anions, Clis found at higher concentration in the effl uent, with 3681.6 mg L -1 , and that it can thus compromise the absorption of N, due to the competition between Cland NO 3 for the same anion transport sites (FERREIRA NETO et al, 2014). Regarding the C/N ratio, the increase in GCSL doses contributes to the signifi cant increase in organic matter (OM) content in the soil.…”
