Abstract

A field experiment was conducted during the 2015 growing season from March to June of 2015 to study the effects of combined applications of organic- P and inorganic –N fertilizers on yield of carrot (Daucus carrota L.) at Menschen fur Menschen Foundation Agro ecology Department Demonstration Site. Factorial combinations of organic –P fertilizer (309kg orga ha-1 with three rates of inorganic N fertilizer (0, 68, and 411 kg Urea ha-1) were used. Treatments were laid down in a randomized Complete Block Design (RCBD) in a factorial combination with three replications. The result of this study revealed that the application of organic –P fertilizer and inorganic- N fertilizer showed a significant differences (P 0.05) difference result was recorded for emergency date and leaf number. The application of 309kg/ha orga + 411kg N/ha as a source urea and 309kg/ha orga + 68kgN/ha as source urea increase plant height by 145.15% and 143.70% over control. Similarly, the application of 309kg/ha orga + 411kgN/ ha as source urea, 309kg/ha orga + 68kg N/ha as source urea, 309kg/ha orga +0 kgN/ha as source urea increased root weight by 174.33%, 149.23% and 129.26% over control. There was also an increase root volume by 170.4%, 150.41% and 145.13% over control for the application of 309kg/ha orga +411kg N/ha as urea, 309kg/ha orga +68kgN/ha as source urea and 309kg orga + 0 kgN/ha as urea respectively
