Hevea brasiliensis, a natural rubber producing species, is widely cultivated due to its high rubber yield potential. Natural rubber is synthesised in the rubber particles of laticifers. Latex diagnosis (LD) was established to characterise the physiological state of the laticiferous system by measuring its physiological parameters, i.e., sucrose, in...
BACKGROUND: Cassava processing is a crucial source of livelihood for rural farmers and processors in Nigeria and Cameroon. This study investigated the varietal effect on the processing productivity of women farmer processors within their working environment and compared this with the food product quality as evaluated by the processors and the field...
Rubber trees (Hevea brasiliensis Muell. Arg.) are a major crop of economic importance in Thailand. The main product harvested from the rubber trees is latex. Latex production depends on a biochemical process for synthesis, degradation, mobilization, and the storage of nonstructural carbohydrates (NSCs), such as starch and sucrose. The rubber trees ...
Rubber (Hevea brasiliensis) latex production is crucial to the local economy, yet Xishuangbanna's climate is considered sub-optimal for rubber cultivation. The prevalence of the powdery mildew disease (Oidium heveae) in this region has decreased the annual latex yield by 20%. Rubber latex yield is influenced by several factors, including temperatur...
Description du sujet. Le débat sur la relation entre la taille des exploitations agricoles et les résultats de production est ancien, mais il n'est pas encore tranché. Au Sénégal, ce débat est alimenté par le fait que les gouvernements récents tendent à favoriser des exploitations irriguées de grande taille, alors que les premiers périmètres distri...
The demand for cocoa has increased over the past years following the growth of cocoa-based products linked to the rise in living standard in highly populated countries. Cacao industry is therefore currently facing the dilemma of producing more cacao while ensuring its sustainability. Cacao monocrops and agroforestry systems (AFS) are two contrastin...
CONTEXT: Cocoa agroforestry systems differ in the diversity of shade tree species composition. Though cocoa benefits from shade, there is a lack of species-specific information on shade trees that enhance soil fertility and yield. OBJECTIVE: We examined how soil characteristics and cocoa yield were affected by eight commonly retained forest tree sp...
Enhancing the value of biomass residues holds promise for mitigating open burning. However, biomass utilization as an energy feedstock encounters its own set of challenges owing to inherent properties. To address these concerns, torrefaction, an essential thermal pretreatment process for carbonaceous materials, emerges as a viable solution. In a la...
Coffee is deemed to be a high-risk crop in light of upcoming climate changes. Agroforestry practices have been proposed as a nature-based strategy for coffee farmers to mitigate and adapt to future climates. However, with agroforestry systems comes shade, a highly contentious factor for coffee production in terms of potential yield reduction, as we...
La rizipisciculture est, d'une part, un modèle agro-écologique durable et, d'autre part, une forme d'intégration agriculture – élevage efficiente. Sur une même superficie de rizière, la production de poissons s'ajoute à celle du riz, avec une augmentation du rendement rizicole de l'ordre de 10 à 20%. La culture riz – poisson contribue à la sécurité...
