“…Pourtant, la microdose se pose comme une solution alternative pour pallier ces contraintes. 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.

Striga hermonthica infection poses a major constraint to sorghum production in sub-Saharan Africa, and low soil fertility aggravates the S. hermonthica problem. Under mineral nutrient deficiency, the sorghum host secretes large quantities of strigolactones, signalling molecules, into the rhizosphere. These induce S. hermonthica seed germination and subsequent infection of the host roots. In a combination of field and glasshouse experiments, we analysed the effect of microdose applied diammonium hydrogen phosphate (DAP) fertiliser on production of strigolactones, S. hermonthica infection and yield of three different African sorghum genotypes (CGM-19 ⁄ 1-1, Lina-3, DouaG). The sorghum cultivars all produced the strigolactones sorgomol and 5-deoxystrigol, albeit in different quantity and ratio. Without fertiliser, high S. hermonthica infection and emergence occurred under both glasshouse and field conditions. DAP application reduced secretion of sorgomol and 5deoxystrigol and reduced S. hermonthica germination (66-70%), emergence (49-73%) and dry biomass (90-96%) under glasshouse conditions. Under field conditions, DAP microdosing reduced S. hermonthica emergence by 40-84% and increased sorghum grain yield by 47-142%. Thus DAP application reduced secretion of strigolactones into the rhizosphere and S. hermonthica parasitism both under controlled and field conditions. Microdosing of DAP may prove to be an efficient and cost effective option to reduce S. hermonthica damage in sorghum in sub-Saharan Africa, particularly in combination with other control options, such as intercropping, use of organic fertiliser and hand pulling of S. hermonthica at flowering to achieve integrated S. hermonthica management.

“…Thus, production techniques involving the management of water and nutrients across the land have been developed, improved and disseminated in the central and the northern region of Burkina Faso (Zougmoré et al, 2002). Zaï association with mineral fertilization by micro dose led to an increase in sorghum grain and straw production (Palé et al, 2009;Barro et al, 2011;Kate et al, 2016).…”

The realization of mechanized zaï with draft animal encounters the weakness of hitch traction capabilities. To overcome this issue, a study was conducted in three villages in the northern Burkina Faso with the aim at evaluating the effect of improved yoke and improved collar respectively with oxen and donkey harnessing on the traction force delivered. The experimental design was a simple randomized bloc comparing improved yoke to classic yoke and improved collar to classic collar. The results showed that the improved yoke allows oxen harness to get 57% more traction force compared with the harness of classic yoke which was 53 daN (P < 0.0001). For the donkey harness there was no statistical difference between the improved collar and the classic one (24 daN and 23 daN). Tillage quality was better with the improved yoke and generates more soil roughness index. This led to increase in sorghum grain yield by 60% (694 kg.ha -1 ) and sorghum straw yield increase by 91% (2688 kg.ha -1 ). The improved yoke increases oxen traction force, dry soil tillage efficiency and sorghum production. These results showed that improved yoke can contribute to an increase in sorghum yield in the northern Burkina Faso.
