Abstract

The aim of the present study was to initiate an adaptation trial and observe the influence of three composts on carrot yield under the agro-ecological conditions of Gbadolite. The experimental design adopted was that of randomized complete blocks with 4 treatments distributed over 3 replications. The total area of the experimental field was 28.8 m2, i.e. 8 m long and 3.6 m wide. Each elementary plot had an area of 2.4 m², i.e. 2 m long and 1.20 m wide. The distance between the blocks was 0.50 m and the plots were also 1.00 m apart. Treatments were as follows: T0: Unamended control plot; T1: Bursary; T2: Chromolaena+legume amendment; T3: Chromolaena+grass amendment. Each treatment was amended with 15kg of compost per bed following the composts. Final planting was carried out at 0.15 m x 0.40 m spacing, with one plant per stake, i.e. a density of 30 plants per plot of 2.4 m2 each. The plot enriched with dung compost yielded 16.75 t/ha (T3); the plot amended with C. odorata + grasses yielded 14.25 t/ha; the plot amended with C. odorata + legume mulch yielded 13.33 t/ha; and the control plot yielded 8.17 t/ha. Carrot cultivation is therefore feasible in the agro-ecological conditions of gbadolite.
