Cowpea is important for food safety in several countries of Africa. In spite of this importance, we have an insufficiency of data on the morphophenologic and nutritional characteristics of Vigna unguiculata in Côte d’ Ivoire. Then, in the present study, analysis of morphological and phenologic traits of 10 cowpea accessions was carried out to identify ideal plant producing simultaneously in quantity seeds and fodder during a short time of culture cycle. The 10 accessions were cultivated under the same pedological and climatic conditions according to a device in block with 5 repetitions. Germination growth and reproduction parameters were evaluated from the sowing to the harvest period. Results show that any accession can be retained as the ideal plant. However, NR2 and NRB1 can be recommended for their high seed yield. NB1 can be retained for the production of seeds and fodder. On the other hand, accessions NN1, NN2, NRB2, NMC1, and NMC2 can be appreciated for a higher length of pods and for their earlier cycle.
Cashew (Anacardium occidentale (L.), Anacardiaceae), a forest plant initially became a cash crop. The national production is in clear progression with the extension of cultivated surfaces. However, the yield remains low. This study aims to assess the situation of producers and cashew nut orchards in the regions of Bounkani and Gontougo. The plantations of selected producers have been visited. An investigation sheet has been completed. Some parameters related to producers and plots were evaluated. Eight sub-prefectures were visited and 240 producers interviewed. The age of the producers was between 30 and 50 years old and 61 to 67% of the producers were uneducated. Average densities of orchards visited ranged from 724 to 769 plants / ha. The highest yield of cashew nuts was obtained in orchards between 21 and 30 years old in the Gontougo region (356.72 Kg / ha). In the plantations visited, only herbicides were used as phytosanitary products. 3.70% of peasants used fertilizers in orchards. Asked about the presence of disease in orchards, 54.17% of producers in the Gontougo region and 51.24% in Bounkani found the diseases. On the other hand, at the level of the 73.96 and 97.52% pests respectively in the plantations of Gontougo and Bounkani observed the presence of pests in their orchards. The annual production of cashew was strongly influenced by the density of plantations.
