Abstract

Field experiments were conducted at the National Horticultural Research Institute, Bagauda between 1999 and 2000 in Kano State to test the responses of two cultivars of roselle namely deep red and pure white to five rates of nitrogen: 0, 30, 60, 90 and 120kg Nha-1. A 2 x 5 factorial experiment was arranged in a randomized complete block design with three replication over two growing seasons or 1999 and 2000. Data collected on plant height, number of leaves, number of branches, pod , stem girth (cm), leaf area index, calyx and seed yields were analyzed using ANOVA .The results for two years showed that optimum N requirements by roselle at Bagauda for plant height was 60kg N/ha for deep red (81.4cm) and 30kg N/ha for pure white roselle (77.7cm), highest number of leaves of 119.6 for deep red and 124.98 for pure white resulted from the application of 60kg N and 18.3 for pure white responded better to 30kg N/ha, number of pods/ plants of 48.2(deep red) at 60kg and 104.6 (pure white) at 30kg N/ha, stem girth of 3.16cm (deep red) and 4.67cm (pure white) at 60kg N and leaf area index (LAI) of 0.25 and 0.40 / plant for both cultivars responded optimally to 60kg N/ha. The calyx yield of 423.0kg/ha fresh weight and 193.0kg/ha dried weight (deep red) were best at 60kg N/ha while 968.0kg (fresh calyx) and 380kg/ha (dried calyx) for pure white responded better to 30kg N/ha. Seed yield of 220kg for deep red and 275kg/ha obtained from pure white were significantly (P<0.05) influenced by the application of 30kg N/ha.
