“…As for the lesser-studied root and tuber crops, good practices for sustainable and low environmental impact sweetpotato and yam production include manure application and mulching to increase soil nutrients and moisture (Bridge et al 2005), as well as crop rotation, intercropping and site cleaning (burning infected plant material) to reduce pest and disease risks (Stathers et al 2003). The use of disease-free growing material and judicious use of chemicals (e.g., dipping vines in insecticide prior to planting to delay infestations) is also recommended to mitigate potentially heavy losses from disease (Lebot 2009).…”

Many environmental factors constrain the production of major food crops in Sub-Saharan Africa and South Asia. At the same time, these food production systems themselves have a range of negative impacts on the environment. In this paper we review the published literature and assess the depth of recent research (since 2000) on crop x environment interactions for rice, maize, sorghum/millets, sweetpotato/yam and cassava in these two regions. We summarize current

“…In addition, the authors reported that the average nematode population per 50 g of tuber peelings at harvest was 1,410 specimens which correspond to approximately 28 individuals per gram of tissue. Although, the application of the treatment significantly reduced the nematode population, according to Bridge et al (2005), populations of S. bradys in excess of 20 nematodes/g of tuber peelings are necessary to produce external symptoms of damage. In the present work, up to 2,727 specimens of P. coffeae per gram of tuber peelings were recorded.…”

The objective of this study was to evaluate the effect of organic-matter incorporated into the soil on population densities of the causal agents of the dry rot disease of yam, under field conditions. The experiment was performed in a natural infested area with a mixed population of Pratylenchus coffeae and Scutellonema bradys, in Quebrangulo county (Alagoas state, Brazil) in a randomized block design with five treatments and five replicates. The sources of organic matter used as soil amendments were: coconut husk powder, castor bean cake, cattle manure and chicken manure. Non amended soil was used as a control. Nine months after planting, the tubers were harvested. No statistical differences were found among disease incidence, yam production and nematode population densities in the soil. However, the application of chicken manure reduced P. coffeae population in tubers.

“…Meloidogyne spp. so far identified to be associated with yam in West Africa are M. arenaria, M. enterolobii, M. incognita, M. javanica, and M. hapla of which M. incognita is reported to be the most important (Bridge et al, 2005;Kolombia et al, 2014). Infected tubers become deformed and disfigured, affecting their quality and marketability, but also act to re-infect following crop cycles if infected tubers are used as seed material.…”
