“…The analysis results showed three basic parameters which were soil type, macronutrients and micronutrients components (Table 3a). According to Kouadio et al (2018) conclusions, we may conclude that the plots were established on a sandy-silty soil. Indeed, there was a sand predominance for 74.35% (Table 3a).…”

“…Therefore, due to this high sand content, this soil has a low retention capacity in exchangeable bases (Kouadio et al, 2018). Accordingly, regarding cotton growing conditions and recommendations (CNRA, 2006;Kouadio et al, 2018), cotton plant needs have been evaluated for fertilizers application (Tables 3b and 3c). Following, the quantities used per ha in T1 and T2 experimental plots were 280 kg for NPKSB-15.15.15.6.1 and 65 kg for urea-46% (Table 3c).…”

The study was set to assess a complementary irrigation effect on seed cotton yields in the Northern Côte d’Ivoire where the cotton is the main cash crop. Firstly, the soil samples were collected from the surface down to 30 cm depth and analyzed. The soil was sandy and silty. So, 65 kg of 46%urea and 285 kg of NPKSB15-15-15-6-1 were applied for its correction. Secondly, in a complete randomized blocks, four tests were conducted, within those were T0 (no complementary irrigation and no crop protection products and fertilizers), T1 (no complementary irrigation, with crop protection products and fertilizers, the cotton cultivation ongoing practice in the Northern Cote d’Ivoire, therefore the reference), T2 (complementary irrigation, along with crop protection products and fertilizers), T3 (only complementary irrigation, without any crop protection products and fertilizers). Thirdly, the tests were replicated in 3 blocks. As a result, from T1 to T2, the plants heights, the plants density at harvest period, bolls number per plant and seed cotton yields were respectively 88.58±1.78 vs 96.08±1.78 cm (+8.47%) at day 73; 53,934±1,260.78 vs 67,593±1,260.78 plants per ha (+25.32%); 23.11±0.81 vs 26.39±0.81 bolls per plant (+14.19%) and 1,616.26±67.86 vs 2,657.77±67.86 kg/ha (+64.44%). Conversely, the complementary irrigation led to higher pest damages on bolls, because 13±2.2% of T2 bolls were attacked, while just 4.6±2.2% of T1 bolls were damaged by insects’ pest. Looking for solutions linked to climate change effects, a complementary irrigation in cotton farms in the Northern Côte d’Ivoire could be profitable to the cotton growers. Nonetheless, the farmers should pay a great attention to the pest management.

“…Cette texture sableuse confère à ces sols un bon drainage, une bonne circulation de l'air et une pénétration facile des racines. Ces sols possèdent de très faibles teneurs en matière organique total et leurs pH eau varie de 6 à 7 (Yoro, 2000 ;N'Gbesso et al, 2017 ;N'Goran et al, 2018). La réserve en eau de ces sols est en moyenne faible et la perméabilité est généralement élevée.…”

Le monde agricole est confronté à des baisses fréquentes de rendements qui sont liées à l’état physique (structure et/ou texture) ou à la non fertilité du sol. Pour y remédier, nous avons eu recourt aux légumineuses alimentaires. Ainsi, une étude a été conduite à la station de recherche sur le coton du Centre National de Recherche Agronomique (CNRA) à Bouaké, en vue d’évaluer l’effet combiné du précédent cultural arachide et du taux en éléments grossiers du sol sur la production du coton. Le dispositif expérimental mise en place a été en blocs de Fisher comportant quatre blocs et cinq traitements (T1, T2, T3, T4 et T5). Les résultats obtenus ont montré que la présence d’éléments grossier influence fortement la résistance à la pénétration des racines, avec des corrélations positives (r = 0,757) et (r = 0,768) dans les tranches (0-20) et (20-40). Ce qui joue négativement sur le développement racinaire (r = -0,820). Le précédent cultural a favorisé le développement des racines dans les traitements T3, T4 et T5. Celui-ci associé à la fertilisation minérale a permis d’obtenir un rendement de (1482 kg/ha) en T4, soit un gain de 58% par rapport à la pratique conventionnelle en milieu paysan (T2). La précédente arachide et les éléments grossiers du sol influencent la production du coton. Ces résultats pourraient être utiles pour les producteurs, dans le choix des parcelles et des pratiques culturales.Mots clés : Cotonnier, précédent cultural, éléments grossiers, développement racinaire. English Title: Effects of the previous peanut (Arachis hypogaea L.) and the loading of coarse soil elements on cotton production (Gossypium hirsutum L.)The agricultural world is confronted with frequent yield reductions that are linked to the physical state (structure and/or texture) or non-fertility of the soil. To remedy this, we have resorted to the use of food legumes. Thus, a study was conducted at the cotton research station of the National Center for Agronomic Research (CNRA) in Bouaké, in order to assess the combined effect of the previous groundnut crop and the level of coarse soil elements on production cotton. The experimental set-up was in Fisher blocks comprising four blocks and five treatments (T1, T2, T3, T4 and T5). The results obtained showed that the presence of coarse elements strongly influences the resistance to root penetration, with positive correlations (r = 0.757) and (r = 0.768) in the slices (0-20) and (20-40). Which negatively affects root development (r = -0.820). The previous crop favored the development of roots in T3, T4 and T5 treatments. This combined with mineral fertilization made it possible to obtain a yield of (1482 kg / ha) in T4, that is to say a gain of 58% compared to the conventional practice in peasant environment (T2). The previous peanut and coarse soil elements influence cotton production. These results could be useful for producers, in the choice of plots and cultural practices.Keywords: Cotton plant, crop precedent, coarse elements, root development.

“…Like other countries in the Gulf of Guinea, Cote d'Ivoire is facing a continuous decline in soil fertility resulting in stagnant or declining cotton yields (5). Soil fertility degradation through nutrient depletion, mainly by erosion and/or crop removal, is one of the threats facing agricultural systems in Cote d'Ivoire.…”

Cotton is the main cash crop in northern Côte d’Ivoire, where intensive cultivation along with low external inputs has led to a decline in crop yields due to soil degradation. The present study aims to assess the evolution of soil fertility during the 2013 and 2021 periods in the cotton basin area of Côte d’Ivoire. More specifically, the study (i) identified the limiting physico-chemical parameters of soil fertility, and (ii) analysed the state of evolution of soil fertility in 2013 and 2021 in the cotton basin of Côte d’Ivoire. For this purpose, a total of 64 soil samples were taken in 2013 and in 2021 on the same cotton plots on the 0-20 cm horizon. Chemical analyses of the soil samples in the laboratory were carried out on the following parameters: particle size distribution, pH water, total nitrogen (NT), Potassium (K+), Calcium (Ca2+), Magnesium (Mg2+), Sodium (Na+) and Cation exchange capacity (CEC). The results of the soil analyses showed that the sandy-clay textured topsoils dominate the whole study area in both years. This leads to a low retention capacity of exchangeable bases. Determination of the soil pH showed that the pH varies from slightly acidic to neutral (6.5<pH<7). The most limiting chemical properties are Cation exchange capacity (CEC) and the sum of the exchangeable bases (SEB) in the department of Korogho, Boundiali, and Ferkessedougou and the most limiting chemical properties in the department of Mankono are CEC. However, during the period from 2013 to 2021 the content of exchangeable cations (Ca2+, Mg2+ and K+) and the base saturation (BS) increased significantly in all the departments, more precisely in the department of Mankono. Although we observed a slight increase in the chemical properties of the soils in 2021 compared to 2013, the values were still below the minimum required threshold. This result implies that the soils have poor physico-chemical properties and consequently a low level of fertility, which compromises the sustainability of the cotton production system. The application of organic and mineral amendments is therefore essential to increase the nutrient content of these soils.
