Evaluacion de los analisis de suelos de las zonas productoras de yuca en Colombia
The results are given of physicochemical analyses of soils and estimated cassava yields for five production zones in Colombia. There was little correlation between yield and the factors studied. Yields tended to increase as P increased; and there was a positive response to K in 2 zones and Ca/Mg in 2 others. However, there were contradictory results with K and pH in three of the zones. Other factors affecting yield should be studied to find the reasons for this discrepancy. (CIAT

Post-harvest management and associated food losses and by-products of cassava in southern Ethiopia
Improved (high yield and disease resistant) cassava varieties were introduced into Ethiopia around the onset of the twenty-first century, as a potential food security crop. At present, limited information is available from the country on post-production aspects of the value chain (VC) and related food losses. The lack of such data prevents policymakers and VC actors from taking steps towards improving VC efficiencies, which can have a significant impact on livelihoods and food security. The focus of this study was to examine the prevailing post-harvest practices in the cassava VC in southern Ethiopia and quantify the extent of food losses and associated by-products in the framework of the recently developed âfood loss and waste protocolâ. The majority of the cassava in the study area was processed into dry chips and milled into a composite flour with teff and maize to prepare the staple bread (injera). âCritical loss pointsâ were during sun-drying (4%) and stockpiling at farm and marketplace (30â50%). Insect pest damage was primarily responsible for food losses at farm and market level. The most important insect species infesting dry cassava were identified during the survey. As far as the by-products were concerned, the ratio of leaf:wood (stem and stump):starchy root on a dry matter basis at harvest was 1:6:10. Further emphasis should be on improving processing and storage technologies to reduce food losses and the better recovery and utilisation of by-products, especially the leaves of cassava, which could be a potential source of protein in human diets
