The participatory research was part of a community-based approach for systems improvement. Grain yields of maize (Zea mays) and bean (Phaseolus vulgaris) following one season of crotalaria fallow were 41% and 43%, respectively, more than following a two-season weedy fallow. Grain yields of maize following a one-season fallow with mucuna and lablab were 60% and 50% higher, respectively, as compared with maize following maize. Maize and bean yield were more, although effects were small, during the second and third subsequent seasons, indicating probable residual effects of the green manures. Mucuna and lablab were successfully produced by intersowing into maize at three weeks after sowing maize, although the yields of the associated maize crop were reduced by 24% to 28%. Farmers estimated the labor requirements for mucuna and lablab to be less than for crotalaria. Farmers independently experimented on how these species can be integrated into banana (Musa spp.), coffee (Coffea robusta), sweet potato (Ipomoea batatas), and cassava (Manihot esculenta) production systems. Farmers reported that the beneficial effects of the green manures included higher food-crop yields; weed suppression; improved soil fertility, soil moisture, and soil tilth; and erosion control. Mucuna and lablab were preferred because of reduced labor requirements and increased net benefits compared with continuous cropping. Farmer participation in the green manure research resulted in efficient generation and adaptation of green manure technology now being promoted in eastern and central Uganda.", "keywords": ["2.

Most soils of the West African savanna zones are so poor that the efficiency of mineral fertilizers, if applied, is very low. For this reason and because of their high cost and unavailability, many small-scale farmers are reluctant to apply fertilizer. This work investigates a fertilizer management strategy using integrated soil fertility management with a leguminous cover crop (mucuna) so as to improve the soil fertility and increase the use efficiency of fertilizer. The experiment was conducted in the coastal savanna of Togo at Djaka Kope. The aim was to evaluate the effectiveness of mucuna short fallow (MSF) in increasing maize grain yield through an improved use efficiency of mineral fertilizer. A 2-year maize\u2013mucuna relay intercropping system was compared with continuous sole maize cropping. Fertilizer treatments were factorial combinations of 0, 50 and 100 kg nitrogen (N) ha\u20131 and 0, 20 and 40 kg phosphorus (P) ha\u20131. While maize grain yield was significantly increased by N fertilization, P did not show any important effect on grain yield. With no N and P applied, grain yield after MSF was on average 40% (572 kg ha\u20131) higher than without. The response to N was much greater than the response to MSF, indicating that N was undoubtedly the key element for maize yield building. P fertilization and MSF together positively influenced the apparent N recovery fraction (NRF). N uptake alone did not reflect on its own the yield obtained, and the relationship between grain yield and N uptake is shifted by MSF, with the grain yield increase per unit of N uptake being higher with than without MSF. Combining MSF and P fertilization may therefore lead to improved N use efficiency, making the application of fertilizer N (lower rates) more attractive to small-scale farmers.", "keywords": ["Soil nutrients", "0106 biological sciences", "2.

Utilis) On Soil Carbon In An Ultisol Under Maize Cultivation In Southern Benin", "description": "<p>Abstract.  Long term fallow is no longer possible in densely populated tropical areas, but legume cover crops can help maintain soil fertility. Our work aimed to study changes in soil carbon in a sandy loam Ultisol in Benin, which involved a 12\uffe2\uff80\uff90year experiment on three maize cropping systems under manual tillage: traditional no\uffe2\uff80\uff90input cultivation (T), mineral fertilized cultivation (NPK), and association with Mucuna pruriens (M). The origin of soil carbon was also determined through the natural abundance of soil and biomass 13C. In T, NPK and M changes in soil carbon at 0\uffe2\uff80\uff9340 cm were \uffe2\uff88\uff920.2, +0.2 and +1.3 t C ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921, with residue carbon amounting to 3.5, 6.4 and 10.0 t C ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921, respectively. After 12 years of experimentation, carbon originating from maize in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil (0\uffe2\uff80\uff9340 cm) represented less than 4% of both total carbon and overall maize residue carbon. In contrast, carbon originating from mucuna in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil represented more than 50% of both total carbon and overall mucuna residue carbon in M, possibly due to accelerated mineralization of native soil carbon (priming effect) and slow mulch decomposition. Carbon originating from weeds in litter\uffe2\uff80\uff90plus\uffe2\uff80\uff90soil represented c. 10% of both total carbon and overall weed residue carbon in T and NPK. Thus mucuna mulch was very effective in promoting carbon sequestration in the soil studied.</p>", "keywords": ["Soil nutrients", "Carbon sequestration", "13C natural abundance", "[SDE] Environmental Sciences", "Soil management", "http://aims.fao.org/aos/agrovoc/c_7170", "Npk", "SOL CULTIVE", "F08 - Syst\u00e8mes et modes de culture", "Soil fertility", "Zea mays", "http://aims.fao.org/aos/agrovoc/c_875", "630", "plante de couverture", "Legume cover crops", "Benin", "http://aims.fao.org/aos/agrovoc/c_1301", "legume cover crop", "Mucuna pruriens", "http://aims.fao.org/aos/agrovoc/c_4971", "ANALYSE STATISTIQUE", "580", "LEGUMINEUSE TROPICALE", "Acrisol", "2.
