Chicken manure, chemical fertilizer and their combination affect yield and post-harvest shelf-life of carrot (Daucus carota L.)
Inadequate cultivation practices of carrots often result in lower yields. Proper soil fertilization combined with a good choice of variety can contribute to both qualitative and quantitative optimization of carrot production. Although several works have been carried out on carrots, there...

Inadequate cultivation practices of carrots often result in lower yields. Proper soil fertilization combined with a good choice of variety can contribute to both qualitative and quantitative optimization of carrot production. Although several works have been carried out on carrots, there is still a lack of information regarding the influence of the types and doses of fertilizers applied in the field by farmers in Cameroon on yield and post-harvest shelf-life of the most frequently grown carrot varieties. This study aimed to determine the interactions between carrot variety and fertilization on the yield attributes and post-harvest conservation of carrots. Nine treatments involving individual and combined applications of chemical fertilizer (NPK: 20-10-10) and chicken manure were tested on five carrot varieties (New Kuroda, Pamela+, Madona, Amazonia, and Vanessa F1) in a split-split plot design with three replications. Yield variables were measured after 110 days of experimentation, followed by measurement of post-harvest shelf-life for thirty days. The best yield was obtained with 10 t ha−1 chicken manure. The variety Pamela+ was the most productive. This fertilizer/variety combination was identified as the best interaction for achieving optimal performance. The maximum storage time observed was 20 days. Application of chicken manure at 5 t ha−1 and 10 t ha−1 and the variety Vanessa F1 were associated with low percentages of deterioration. The best shelf-life was achieved with the variety Vanessa F1 fertilized with 5 t ha−1 of chicken manure, which showed the lowest deterioration (8.33% after 20 days of storage). |
