The exploitation of peppers is oriented by their characteristics, namely and first the pheno-morphological ones. Those of peppers from the Haut-Sassandra region (Côte d’Ivoire) are poorly described. In order to establish them, 18 accessions were characterized from eight quantitative parameters in a five-repeat incomplete random block trial. The analyses revealed accessions with opposite and similar characteristics. Thus, the accession Bec d’oiseau collected in Zoukougbeu, with a long germination period (9 days), good growth and good vegetative development, the largest leaf area (26.61 cm2), is it the most different accession of the 17 others. Also the accession Inconnu collected in Daloa stood out with the shortest time to germination (5 days), good growth and vegetative development, the second highest plant height (23.02 cm), but low lateral growth and leaf area. Likewise, the accession Bec d’oiseau from Issia stood out with the longest time to germination (10 days), average growth and development. The other 15 accessions formed a cluster, with a relatively short to relatively long time to germination (6-8 days), relatively slow growth and vegetative development. This study showed the existence of an important pheno-morphological diversity within the 18 accessions of peppers studied. Time to germination, plant height and leaf area were particularly discriminant of these accessions. The characteristics of these peppers can be exploited in breeding.

This study highlighted the symbiosis between Anabaena-azollae cyanobacteria and Azolla aquatic fern in the production of Azolla filiculoides and its use as a biofertilizer. His trial of vegetative production using ordinary water + dung, carried out in 14 days of culture, showed a significant amount (6473g). Then, the use of this one as an amendment for the growth of CB-one rice, showed its positive impact on soil fertility thus translating high yields of CB-one rice contrary to the unamended witness. Indeed, with this treatment, the average number of tillers observed after 56 days of culture, was 18.1 ± 4.23 tillers contrary to the NPK (15.83 ± 4.98) and the control (10, 4 ± 3.27). The average number of leaves was significant in Azolla (57.20 ± 13.45), average for the NPK fertilizer (48.86 ± 15.79) and low for the control (34.83 ± 14, 52). In sum, the trays treated with Azolla filiculoides produced many more panicles and grains compared to treatments. As a result, Azolla is likely to restore soil fertility by providing the soil with the nutrients needed for crop productivity.
