Abstract

tuber yield of Carrot in the Botanical Garden of the University of Ilorin, Ilorin, Kwara State, Nigeria, between April and August, 2018. The experiments were arranged in a complete randomized design (CRD) with six treatments (T0, T1, T2, T3, T4 andT5) of three replicates each.Data on number of leaf, leaf height, leaf petiole girth, root tuber girth and root tuber length were taken and analyzed with Analysis of Variance (ANOVA) using SPSS package and means were separated by Duncan Multiple Range Test (DMRT). The results revealed that all growth and yield parameters were significantly improved by organic and inorganic fertilizers. The highest values for number of leaf (16.67), leaf height (18.33cm) and leaf petiole girth (0.30cm) were obtained in organic fertilizer from poultry dung. These values were much higher than those obtained in inorganic fertilizer. Inorganic fertilizer (NPK) showed the highest value (5.17cm) for root tuber girth, followed by control (4.93cm) and least (3.93cm) in organic fertilizer respectively. Highest root tuber length (7.33cm) was obtained in inorganic fertilizer treated carrot plants, followed by control experiment (6.97 cm) and least in organic fertilizer (6.27cm).This study concluded that the application of organic and inorganic fertilizers enhanced increase in all growth and yield parameters like leaf rachis girth, leaf height, number of leaf and root tuber.
