The present study determines the effects of tillage methods
and physico-chemical properties of soil on agro-morphological properties and
yield of Cassava (Manihot esculenta Crantz) in Abongoua, Côte d'Ivoire. Various
cultivation techniques have been initiated, including plowing, which aims to
create a favorable environment in the soil for the development of cultivated
plants. It is through these cultivation techniques improve the structure of the
soil, and its physical state and consequently increase its permeability and
porosity, creating conditions more suitable for the development of tuberous
roots. The experiment was conducted in the field for 13 months (June 2019 to
July 2020) in Abongoua in the department of Bongouanou (East-central Côte
d'Ivoire). After cleaning a 900 m2 fallow surface and cleaning all plant
debris, soil samples were taken with an auger in the 40 cm surface in each
corner and in the center of the experimental plot to form the composite sample
for laboratory analysis. The cuttings were directly sown at a rate of 12
cuttings per treatment. The data for the various parameters obtained were
subjected to an analysis of variance (ANOVA) using SAS software version 9.4,
and the means were separated using the Newman and Keuls test at the 5% probability
level. The findings revealed an acidic soil with a sandy texture and an
abundance of nutrients, particularly major elements, trace elements, and the
clay-humus complex. In decreasing order of importance, treatments T3 (ridged
soil), T2 (mounded soil), and T1 (tilled soil) produced good growth and
development of agro-morphological parameters as well as yield (T0). The study
clearly demonstrated that the kind of tillage, particularly the ridged tillage
technique, enhances cassava agromorphological parameters, productivity, and
yield. What we recommend to farmers in the area for a good cassava harvest in
Abongoua, East-Central Côte d'Ivoire.
