To find an alternative to the use of nitrogenous fertilizers in sugarcane cultivation, this study was initiated in order to improve soil fertility and sugarcane yield by growing legumes. The trials were carried out on-farm according to split-splot design in ferké 1 sugar bowl northern Côte d’Ivoire. The main factor was the cropping system (4 levels) and the subsidiary factor was the treatment with urea (3 levels). On the experimental plot, two legumes fallows (Soybean and Lablab) were grown in rotation with sugarcane.

Medicinal plants of Côte d’Ivoire and viral infections: Diagnosis of Begomovirus | IJAAR

By: J. A. N’cho

Abstract

diseases pose a real threat to their culture and development. It is useful to determine the health status of medicinal plants in Côte d’Ivoire. Surveys and collection of samples were made at sites identified in Abidjan, Alépé and Yamoussoukro. The symptoms observed were mentioned. Herbal hosts of Begomovirus, incidence and severity of these symptoms have been identified.

Abstract

The length-weight relationship, condition factor and proportionality index of Callinectes amnicola and Cardisoma armatum from Ebrié Lagoon, Grand-Bassam, Côte d’Ivoire, were studied. The carapace width and length were measured to the nearest millimeter (mm) while weight was measured to the nearest grams (g). The length-weight relationship of all samples collected were determined for the various sexes and mixed populations. The values of the exponent ‘b’ for all the sexes and mixed populations ranged from 2.01-2.69. The growth generally exhibited negative allometry in all the sexes and mixed populations. The proportionality index showed that Cardisoma armatum was longer and Callinectes amnicola was wider.

Occurrence of Babesia spp in bovine breeding in Poro area (Côte d’Ivoire) – IJAAR

By: Yahaya Karamoko

Abstract

Babesia spp is an emergent pathogenic which constitute a major constraint in bovine breedings in Côte d’Ivoire. Little information on Babesia exists in Poro area. A study was carried out on 120 bovine blood samples, with an aim to evaluate Babesia prevalence. Microscopic technique was used to determine prevalence of Babesia (19.17%). Hematocrit values varied from 20 ± 0.00% to 41.44 ± 7.47%.
