Agronomic and biochemical evaluation of some ecotypes of cowpea [Vigna unguiculata (L.) walp. (Fabaceae)]Collected in Côte d’Ivoire

Abstract

This work aims to propose to the peasants producing varieties of seeds, biomass and to determine some physico-chemical characteristics of these seeds. Thirteen agronomic parameters and 8 characters were evaluated. The got results showed an important variability between the ecotypes. The most relevant variables which make it possible to describe variability between the groups are the number of pod, the number of seeds, the weight of the hulls, the biomass, and the rate of filling, the height and the scale. Thus, the varieties N21DR, N10BBrp, N8BRcp, and N18ZRET N9BN produced more seeds whereas the varieties N15ZBoNg and N7BRc produced more air biomass. They can be selected at agronomic ends within the framework of the fertilization of the grounds. The results revealed that the seeds are energy foods, rich in proteins and glucids. On the other hand, they are low in lipids, ashes and have low moisture being able to facilitate their conservation over one relatively long period. The cultivar N1KBN which recorded the highest ash content could be used in the fortification of food. Cultivar white N1KBN recorded the highest content of proteins. Consequently, its seeds could be used to supplement traditional food and to be recommended in the sector of the made up flours. The use of seeds in these fields could contribute to reduce the protein deficits at certain poor populations, in the grip of protein-energy diseases.

Ethnobotanical investigation and Morphobiometric Characterization of different Cowpea seeds (Vigna Unguiculata Subsp. Unguiculata (L.) Walp) in the Hoggar region (Algerian Sahara): acquisition And future investment project for food security in Algeria

“…Similarly with results from other cowpea varieties in Nigeria and Togo [16], Ghana and Mali [17]. However, the Weight of 100 seeds (WHS) are recorded an average low than some researchers have found in this field [18][19][20][21][22][23] . this differences are due to the adaptation to the specific arid conditions of Hoogar which results in reduction in the size and weight of the pods and seeds , Hoover the dimensions of cowpea and their weight of 100-seed give indication of the space the flour would occupy as well as their bulkiness [19,24] .…”
