This study was conducted to investigate the influence of nitrogen (N) nutrition on fruit quality and shelf life of cucurbitaceous vegetable, bitter gourd (Momordica charantia L.) using poultry manure as an organic source. Three levels of nitrogen (200, 250 and 300 kg N haâ1) were applied in three ratios of organic-chemical N substitutions (1:1, 1:2, 2:1) at three different frequencies of application. The experiment was laid out as confounded 33 design in 9-plot blocks with two replications confounding LR2F in RI and LRF2 in RII. The crude protein, total phosphorus (P), potassium (K), and iron (Fe) content of fruits increased with increasing levels of N application and were highest with 300 kg. Highest iron content was recorded (0.10%) with higher doses of N. Higher levels of N nutrition reduced the ascorbic acid content in fruits. More frequent split application of nutrient N or greater proportion of organic source enhanced the shelf life of fruits.View full textDownload full textKeywordsbitter gourd, nitrogen substitution, poultry manure, shelf life, split applicationRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01904167.2012.676127

机译：以家禽粪便为有机源，研究了氮（N）营养对葫芦科苦瓜（Momordica charantia L.）的果实品质和货架期的影响。在有机氮的三种化学取代比（1：1、1：2、2：1）下，施用了三个氮水平（200、250和300 kg N ha â1）三种不同的应用频率。实验布局为在9个图块中混杂3 3 设计，其中两个重复使RI中的LR 2 F和RII中的LRF 2 混杂。水果中的粗蛋白，总磷（P），钾（K）和铁（Fe）含量随着施氮量的增加而增加，最高时为300 kg。氮含量最高时，铁含量最高（0.10％）。氮含量较高时，水果中抗坏血酸含量降低。营养素N的更频繁的分次施用或更多比例的有机源可以延长水果的保质期。查看全文下载全文关键词苦瓜，氮置换，家禽粪便，保质期，分开施用，services_compact：“ citeulike，netvibes，twitter，technorati，美味，linkedin，facebook，stumbleupon，digg，google，更多”，发布号：“ ra-4dff56cd6bb1830b”}；添加到候选列表链接永久链接http://dx.doi.org/10.1080/01904167.2012.676127
