Effects of tillage methods and poultry manure rates on the production of Carrot (Daucus carota L) in Nsukka, Southeast Nigeria

Carrot (Daucus carota L.) has historically been classified as a northern crop because it predominantly grows in the regions of Nigeria. Transportation harvested roots to south consequently resulted decay, shrinkage, loss due high temperature and long distant travels, cost produce etc. The objective was find out variety tillage method that will enhance production carrots Southeast Nigeria appropriate poultry manure rates for production. Two varieties (Touchon mega Kurado) were evaluated under field experiment grown three (PM) (0,5,10 t ha-1) two methods (Ridge Bed) assess their effects on growth yield carrot roots. Roots at 90th day after planting data collected seedling emergence, root weight, leaf whole plant biomass, percentage marketable yield, total yield. result showed significantly (p<0.05) enhanced higher yields. ridge gave than Bed type. Kurado had highest percent though there no significant (p>0.05) differences between varieties. influenced suggesting rate environment. From results experiment, could be concluded environment is recommended its yielding capacity while Ridge farmers area efficient use ability support penetration; 10 ha-1 found most economical rate. Key words: Tillage methods, variety.
