“…Cattle manure with moisture content of 15 % was used for the experiment. Mineral fertilizer application was a micro-dose of NPK at a dose of 3 g per hole (62 kg ha −1 at a sowing spacing of 80 cm × 60 cm) [19]. Varieties and cropping systems were combined to have 8 levels of treatment (M1, M2, C1, C2, M1C1, M1C2, M2C1 and M2C2).…”

Background:In search of options to cope with climate change and variability, a trial combining fertilization and improved varieties of millet and cowpea (intercropped or as sole crop) was conducted on three sites (Lemnogo, Tibtenga and Ramdolla) in the northern region of Burkina Faso. The application of cattle manure (3 t ha ) of a mineral fertilizer composed of 14 % N, 23 % P 2 O 5 and 14 % K 2 O (NPK), their combination and a control (no manure and no NPK) as four soil fertilization options, two improved varieties of millet (SOSAT-C88 and IKMP5), two varieties of cowpea (KVX 396-4-5-2D and KVX 61-1) and two cropping systems (millet-cowpea intercropping, sole crop) were tested on-farm for two seasons (2013 and 2014). During the third season a survey was conducted on the acceptability by farmers of the tested combinations as a way of buffering or coping with rainfall variability.Results: Two-year trial revealed that the combination of manure and NPK applied to the intercropping of millet and cowpea significantly increased crop production (land equivalent ratio = 1.83 ± 0.18 and 1.78 ± 0.20, intercropping millet variety IKMP5 with cowpea KVX 61-1 and intercropping millet variety SOSAT-C88 with cowpea KVX 396-4-5-2D, respectively). During erratic rainfall year, intercropping millet IKMP5 and cowpea KVX 61-1 performed the best, while under well-distributed rainfall conditions, intercropping millet SOSAT-C88 with cowpea KVX 396-4-5-2D displayed higher production, respectively, for millet and cowpea. Some varieties were not well accepted by most farmers (based on a survey of 36 farmers) mainly because of loss in grains before harvest for millet IKMP5 (97 %) and high grain attacks by insects in storage for cowpea KVX 61-1 (89 %). The alternative for farmers rejecting these varieties could be the intercropping of millet SOSAT-C88 and cowpea KVX 396-4-5-2D fertilized with manure. Conclusions:Making weather forecasts and related agronomic advices available to farmers in this region will allow them to better plan their agricultural practices such as mineral fertilizer application and will also be a great move toward climate-smart agriculture. Developing more performant storage measures that drastically reduce insect attacks for some of the tested varieties (cowpea KVX 61-1, for instance) could contribute to promoting their adoption.

“…En effet, ces auteurs étaient parvenus à la conclusion que la différence entre la microdose et la dose vulgarisée n'était pas statiquement significative. De même, des études récentes ont montré des résultats similaires avec le mil sur des sols sableux du Niger (Tabo et al, 2007 ;Hayashi et al, 2008;Ibrahim et al, 2014Ibrahim et al, , 2015 ainsi qu'avec le niébé et le sorgho au Mali (Bagayoko et al, 2011) et au Burkina Faso (Taonda et al, 2008Pale et al, 2009).…”

“…La microdose consiste à des apports de petites quantités d'engrais minéraux dans les poquets (Tabo et al, 2005 ;Taonda et al, 2008 ;Palé et al, 2009 ;FAO, 2012). De nombreuses études ont mis en évidence le rôle positif de la microdose dans la réduction des pertes diverses des nutriments (Demers, 2008), l'amélioration de l'efficience d'utilisation des nutriments par sa concentration au niveau du système racinaire (Tabo et al, 2006(Tabo et al, et 2007Palé et al, 2009).

RESUMELa baisse de la fertilité des sols agit fortement sur la productivité des cultures et par conséquent, le revenu des agriculteurs. L'utilisation des engrais minéraux permet d'améliorer la productivité des sols mais son accès reste limité aux petits producteurs. L'objectif de la présente étude est d'évaluer l'efficacité agronomique et économique de la microdose selon la toposéquence. Des tests ont été implantés suivant la toposéquence pendant deux ans et des enquêtes ont été menées auprès des ménages pour évaluer la rentabilité de la technologie. Effects of fertilizer microdosing on cowpea, millet and sorghum production as a function of the toposequence ABSTRACT The decline in soil fertility has a strong effect on crop productivity and, consequently, on farmers' incomes. The use of mineral fertilizers improves soil productivity, but access is limited to small-scale producers. The objective of this study was to evaluate the agronomic and economic efficiency of the microdose according to the toposequence. Tests were carried out following the toposequence during two cropping seasons and household surveys were conducted to assess the cost-effectiveness of the technology. NPK (14-23-14) fertilizer was applied on cowpea and sorghum at a rate of 2 g / pit and 3 g /pit for millet pocket (62.5 kg/ha). Urea was applied only on sorghum and millet respectively at a rate of 1 g/pit (31.25 kg/ha) and 1.5 g/pit (46.88 kg/ha). These treatments were compared with the recommended fertilizer rate and an absolute control. Microdose increased grain yields by 143%, 134%, and 155% respectively for sorghum, millet and cowpea compared with the control. Microdose was economically more profitable than the recommended fertilizer rate.

“…Tabo et al (2006) have shown that micro-dose (4 kg P/ha) increased millet and sorghum grain yields up to 43-120% and farmer's income were improved trough Warrantage by 52-134% in the studied countries (Burkina Faso, Mali et Niger) (Table 6.1).…”
