Effect of Different Cropping Systems on the Growth and Yield of Ginger (Zingiber officinale Roscoe) in Daloa, Côte d’Ivoire

Abstract

Aims: The aim of the present study was to develop a technical itinerary to improve ginger cultivation. Study Design: The experiment was laid down in three blocks completely randomized consisting of three cultivation techniques with three replications. Place and Duration of Study: Department of Agronomy and Forestry, Jean Lorougnon GUEDE University Université (Daloa, Côte d’Ivoire), experimental farm of Laboratory for the Improvement of Agricultural Production, between February 2024 and January 2025. Methodology: To achieve this, three cultivation techniques were studied. Dark yellow-fleshed ginger rhizomes with three buds are sown on flat soil, on ridges, and on mounds. Sowing was carried out for 10 ridges, each containing five sowing holes. A total of 50 rhizomes were sown for the ridge factor. For the mounds, 50 mounds were created, each containing one rhizome. For the trials on flat soil, 10 rows of seedlings, each containing five rhizomes, were studied. A total of 50 rhizomes were sown for this last factor. For all factors studied, the spacing between sowing hole was 0.5 m within the same row and between rows. Observations were made on six agronomic parameters (number of leaves per plant, leaf length, leaf width, leaf area, plant height and rhizome weight per plant). Results: Results indicate that cultivation techniques significantly influence the agronomic parameters (P ˂ .001). Thus, the mound cultivation technique gave the highest values for most of the agromorphological parameters studied, mean number of leaves per plant (230.2 ± 22.0), leaf width (3.01 ± 0.71 cm), leaf area (37.98 ± 4.71cm2). While ridges cultivation technique gave the lowest yields for all agronomic parameters. The most optimal yield was achieved through the implementation of the mound cultivation technique. The rhizomes harvested from the mounds have mean weight per plant of 547.1 ± 90.1g. Conclusion: These findings provide valuable cultivation techniques for optimizing ginger production. The mound cultivation technique improves ginger production outcomes.
