摘要

田间试验于2000年和2001年雨季在巴古达(北纬110 - 33′,东经80 - 23′)国家园艺研究所进行。本试验旨在评价蔷薇品种对不同施氮水平和50 kg P/ hm2的响应,确定蔷薇最适氮肥需要量。采用3个重复的完全随机区组设计,采用0、30、60、90和120 kg N hm -1 5个氮肥配施量。施氮量显著增加。在北几内亚热带草原上,施用50 kg磷/ha对2001年度玫瑰色品种的种子产量有显著(P 0.05)的影响,60 kg氮/ha对深红色品种的种子产量和纯白色品种的种子产量有显著影响,分别为690.0 kg/ha和550.0 kg/ha。

Effect of nitrogen fertiliser on the growth and calyx yield of two cultivars of roselle
Field experiments were carried out during the 2000 and 2001 rainy seasons on the field of National Horticultural Research Institute at Bagauda (latitude 11o 33’ N and longitude 8o 23’E of the equator). The experiment was aimed at evaluating the response of roselle cultivars to different levels of N in combination with 50 kg P/ha and establishing an optimum N fertilizer requirement by roselle. Five rates of nitrogen (0, 30, 60, 90 and 120 kg N ha-1) were combined with deep red and pure white cultivars of roselle in a randomized complete block design arrangement with three replications. Application of N significantly (p o roselle. Application of 50 kg P/ha as basal dressing significantly (p 0.05) were recorded in the seed yields of roselle cultivars in 2001 season and 60 kg N/ha produced optimum levels of 690.0 kg/ha for deep red and 550.0 kg/ha for pure white cultivars seed yields in Northern Guinea savanna.
