Abstract

Date et densité optimales de semis du niébé en association avec le mil.

Contribution of arbuscular mycorrhizal fungi to the bioavailability of micronutrients (iron and zinc) in millet accessions

“…The application rates of cow dung and horse manure were determined based on their nutrient content (N, P, and K) in conjunction with the nutritional requirements of the pearl millet plants, as outlined in previous studies ( Ouendeba and Teme, 2011 ; Mbaye et al., 2014 ) and summarized in Table 2 . Inorganic fertilizers were additionally applied to fulfill the N and K requirements of the crops, as specified in Table 2 .…”

Influence of nitrogen fertilization (urea) and association with a legume (Vigna unguculata L.) on the Nutritional Value of three potentially dual-purpose Millet Accessions and Thialack 2 and Souna 3 Varieties in Senegal

“…The growth of two or more crops in combination often results in lower yields of both crops due to competition for limited essential resources 16 -18. Mbaye and al. 19 , working on different dates and seedling densities of cowpea associated with millet found no significant effect of cowpea on millet productivity and showed that the results differ by one year from other depending on dates and sowing densities.…”

Sorghum [Sorghum bicolor (L.) Moench] and cowpea [Vigna unguiculata (L.) Walpers] intercropping improves grain yield, fodder biomass, and nutritive value

“…For cowpea, they were done from 25 to 30 July and 28 July to 3 August in 2019 and 2020, respectively. Cowpea sowings were shifted approximately 10 days later from those of sorghum in order to optimize its grain yield and biomass (Mbaye et al, 2014). Spacing was 80 cm between rows and 40 cm between plants within rows for all cultivars.…”

“…These comparative advantages can be explained by the beneficial relationships of complementarity between the two associated crops for the use of nitrogen resources, space (very different aerial architectures), and growth peaks (Justes et al, 2014;Barro et al, 2016;Louarn et al, 2016). Shifting the sowing date between the two associated crops reduces the interspecific competition (Mbaye et al (2014). Indeed, the symbiotic fixation of atmospheric nitrogen by cowpeas limits its competition with sorghum, which uses mineral nitrogen in the soil.…”

“…Cereal and legume intercropping is more suitable for agropastoralists and sedentary crop-livestock farmers because of this dual need for food and feed for human beings and livestock, respectively (Nasir et al, 2019). The use of improved food-feed cultivars, which can fit into smallholder farmer's cropping calendar, is likely to provide greater benefits both for grains and fodder biomass (Mbaye et al, 2014;Louarn et al, 2016;Abera et al, 2021;Sanfo et al, 2023). Previous studies revealed that intercrop of maize-cowpea-sorghum-cowpea led to an increase in grain yield and fodder biomass in the range of 30-60% with better weed control (Matusso et al, 2014;Obulbiga et al, 2015;Coulibaly et al, 2017;Sanfo et al, 2023), and land equivalent rations were greater in cowpea-maize intercropping systems (Sanfo et al, 2023).…”
