The results of these trials show that using pigeon pea for pig feed had positive impact on the Average Daily Growth (ADG) rate. The ADG obtained after 150 days with Groups 2 (523 g/days) and 3 (529 g/days) were significantly higher (P

This cattle breed used seems well adapted for fattening and showed a strong response to improved fodder. However, this bull fattening activity presented two major constraints.First, it seems difficult for smallholders to carry out this kind of livestock production without technical support and use of fertiliser (thermophosphate). The second limiting factor could be that the system was first perceived as requiring an initial cash investment.Development of specific market channels for forage seed production could indirectly improve pasture management, avoid high stocking rates and generate new income that could be invested in fertiliser and animal care. A global approach involving credit access, technical and political support has to be defined to develop productive and efficient livestock production on this ecology. This poses a great challenge which, if grasped, could yield great benefits on the upper part of the Nam Ngum river basin.

The results of the WSA analysis are promising, highlighting the positive features of forage species like B. ruziziensis and S. guianensis, which seem able to aggregate smaller soil particles. Annual records should be made for B. ruziziensis, S. guianensis and others systems, and linked with analysis of microbial activities to show the beneficial functions of each species or system in soil aggregation. It is difficult to interpret the positive features of species in regard to bulk density and soil permeability as interaction is complex and various parameters are involved. At the same value of bulk density, this parameter will be affected by article size and arrangement, and organic content. In the case of rice and pine forest, the lower bulk density is mainly related to macro-porosity (high level of permeability). In contrast, B. ruziziensis and S. guianensis showed, for lower Da, a lower value of permeability probably related to an increase of micro-porosity. This characteristic has to be analysed during subsequent measurements of Da and soil permeability data as micro-porosity is a main component influencing water retention.

The results of these surveys show that there are currently more than 1,200 smallholders using DMC systems on a total of about 1,500 ha of cultivated land. Overall, the rates and levels of DMC systems’ adoption by smallholders appear more important in areas where the environment is the most degraded and/or particularly fragile (case of Nongphakbong village, Botene district). In contrast, in less environmentally-degraded and less fragile areas, the level of DMC systems’ adoption is still rather limited. With more productive soils, mechanized mono-cropping can still provide high profits and, as such, retain the interest of a majority of farmers (case of Bouamlao village, Paklay district)

Methodology of DMC. A Holistic Approach to Generate, Adapt, Validate andDisseminate Technologies with Smallholders

A sector-based program in agroecology for a national extension of DMC According to the results obtained by the Lao National Agroecology Program (PRONAE), the Council of Ministers asked, on the one hand, to the Ministry of Agriculture and Forestry (MAF) to promote DMC technologies to the whole of Lao PDR and, on the other hand, that this approach is registered in he university and school courses. The national authorities required from Cirad and AFD a support for the implementation of a sector based program in agroecology

Comment fait-on le Coton SCV : recommandations pratiques?

Mucuna pruriens est une légumineuse rampante et volubile qui nécessite des sols de fertilité moyenne, bien draînés et peu compactés. Ses graines sont traditionnellement utilisées comme aliment pour les animaux. Elle est agressive contre les mauvaises herbes (ombrage). Sa production de graines est aisée. Elle est facilement contrôlable par fauche et elle disparaît après l’hiver. Sa fixation symbiotique de l’azote atmosphérique en fait un excellent précédent pour le maïs.
