Qualidade do fruto verde de coqueiro em função da irrigação com água salina
Open accessAbstract
Foram estudados, neste trabalho, os efeitos de quatro níveis de salinidade da água de irrigação (0,1, 5,0, 10,0 e 15,0 dS m-1) obtidos mediante adição de NaCl, na qualidade de frutos de coco (Cocos nucifera L.) cultivar Anão Verde do Jiqui, com 3,5 anos de idade e na salinização do solo. O ensaio foi conduzido em blocos inteiramente ao acaso, em solo de textura arenosa não salino, utilizando-se de sistema de irrigação por microaspersão, no município de Parnamirim, RN, durante o período de janeiro/2000 a março/2001. A qualidade do fruto foi avaliada com base no peso médio, volume de água, ºbrix, e composição iônica da água. A salinidade da água de irrigação reduziu o peso médio e o volume de água dos frutos, elevando o teor de açucares (ºbrix) a concentração iônica expressa pela condutividade elétrica (CE) da água do fruto. Os íons em maior concentração na água de coco foram o cloreto e o potássio. A CE do extrato de saturação do solo, 11 meses após iniciada a irrigação, aumentou até à profundidade de 0,80 m, em função da concentração salina da água de irrigação, atingindo valores superiores a 4 dS m-1 principalmente nos últimos dois níveis de CE (10 e 15 dS m-1).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
