Effect of cattle manure on growth and yield of carrot (Daucus Carrota L.) under Jimma condition

So far, research has been conducted to know the effect of cattle manure fertilizer on growth and yield of carrot under Jimma condition. Experiment was conducted at Jimma University College of Agriculture and Veterinary Medicine at horticulture garden during 2016 cropping season under irrigation condition. Experiment was laid out in randomized complete block design and cattle manure applications with four treatments (0, 5, 10 and 18 tons per hectare) were used. Each treatment was replicated three times. Data was collected from five randomly taken plants per plot. The finding revealed that application of cattle manure on carrot showed a highly significant effect for growth parameters (plant height, canopy diameter, root length and root diameter). Application of cattle manure at 10 tons ha⁻¹ increased carrot root weight by 48.8% compared to the non-fertilized control treatment. Therefore, this finding would be a base for future research to be conducted.
