RESUMEN
Little is known about folk perception of pearl millet livestock fodder status across the Niger republic. Thus, this work assesses farmers' perceptions of the main pearl millet accessions fodder performance features in Niger. To that end, we: (i) Identify farmers' criteria for choosing pearl millet accessions fodder-profile, (ii) Analyze the farmer preferences for pearl millet accessions adapted to local cropping systems, and (iii) Analyze current cropping systems. Data have been derived from semi-structured surveys based on individual and focus group interviews of 508 stakeholders which were sampled from seven major ethnic groups across the eight country regions. Generated database was submitted to multivariate analysis in XLSTAT software. As results, the farmers' perception of a fodder profile may combine long and wide leaves, abundant tillers, slender stems, coupled to a large biomass and a plant capacity to regrow after grazing or mowing. Height accessions were agro-ecologically and socio-culturally chosen and valued by Farmers across the country, i.e. Haïni Kirey at Tillabéry, Niamey and Dosso, HKP and Guerguéra at Tahoua, Ankoutess at Agadez, Goudiss and Môro at Diffa, Batoukouché at Zinder, and HKP and Zongo at Maradi. Distinctive producers' groups occur despite wider similarities in crop management practices. The prominent cropping system associated pearl millet to cowpea or groundnut. Therefore, identifying, characterizing or improving pearl millet accessions with a grain or fodder profile requires significant involvement of the farmers across Niger.

RESUMEN
BACKGROUND: An ethnobotanical study was conducted in the eight regions of Niger to identify local knowledge variation of millet (Pennisetum glaucum (L.) R. Br) uses. In fact, the level of individual knowledge can be affected by many factors such as gender, age, ethnicity, occupation, religious and cultural beliefs, etc. This study documented indigenous knowledge of millet uses in Niger and aimed specifically to (i) identify the different types of millet organ uses and (ii) assess the variation of local knowledge of millet uses along with ethnicity, occupation, and age. METHODS: The data were collected in 32 major millet-producing villages in Niger through individual semi-structured interviews and focus group discussions. About 508 individuals from 5 ethnic groups were interviewed. The assessment of the knowledge was performed by calculating five ethnobotanical indices such as the number of reported uses by parts of the plant (RU), the use-value of the parts of the plant (PPV), the specific use-value (SU), the intraspecific use-value (IUV), and the relative frequency of citations (FRC). Data were analyzed using descriptive, univariate, and multivariate statistical analyses. RESULTS: The results indicated a significant variation in uses across ethnic groups (H = 38.14, P = 0.000) and socio-occupational categories (H = 6.80, P = 0.033). The Hausa, Kanuri, and Zarma-Sonhrai ethnic groups, farmers were the largest users of the species. Dietary (51.40%) and forage (40.35%) were the most reported uses. The most commonly used parts of the plant were the stubble (74.92%) and grains (73.68%). CONCLUSIONS: The study showed the importance of P. glaucum in the daily life of local people. It also confirmed the uneven distribution of indigenous knowledge of millet uses in Niger due to social factors. Now, the challenge is how to incorporate these social differences in knowledge of millet uses in view to sustainable management and conservation of local genetic resources of millet. Finally, this work could be an important decision-making tool for future millet valuing.
