Adubação com NPK em coqueiro-anão-verde (Cocos nucifera L.) rendimento e qualidade de frutos
Open accessAbstract
A produção de coco para extração de água no Estado de São Paulo está em expansão. Entretanto, faltam informações básicas sobre o manejo desta cultura. Desse modo, instalou-se um experimento de campo em Pereira Barreto (20º47'S; 51º01'W), visando ao estudo da resposta do coqueiro à adubação com NPK de set/2000 a fev/2004. Empregou-se o esquema fatorial fracionado 1/2 (4³), sendo os tratamentos formados pelas combinações de doses anuais de N (0; 120; 240 e 360 kg ha¹ de N), P (0; 100; 200 e 300 kg ha¹ de P2O5) e K (0; 120; 240 e 360 kg ha¹ de K2O). Como fontes de N, P e K, respectivamente, aplicaram-se NH4NO3, superfosfato triplo e KCl, fracionadamente, durante a época das chuvas. A aplicação de N causou diminuição no volume de água e massa média dos frutos e na quantidade de frutos por cacho; inversamente, a adubação potássica teve efeito positivo nestas características. Os teores de P e K da água de coco aumentaram com a aplicação de P e K, entretanto não houve efeito dos tratamentos nos resultados da avaliação sensorial. A aplicação de P não teve efeito significativo na produção de frutos.

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.
