“…However, health of people may be affected [31], particularly in years when drought has affected other crops, which increases people's dependency in cassava. In addition to higher consumption of cassava roots, drought generally increases CG levels in them [32].…”

Vitamin A deficiency (VAD) is a preventable tragedy that affects millions of people, particularly in sub-Saharan Africa. A large proportion of these people rely on diets based on cassava as a source of calories. During the last two decades, significant efforts have been made to identify sources of germplasm with high pro-vitamin A carotenoids (pVAC) and then use them to develop cultivars with a nutritional goal of 15 μg g −1 of β-carotene (fresh weight basis) and good agronomic performance. The protocols for sampling roots and quantifying carotenoids have been improved. Recently, NIR predictions began to be used. Retention of carotenoids after different root processing methods has been measured. Bioavailability studies suggest high conversion rates. Genetic modification has also been achieved with mixed results. Carotenogenesis genes have been characterized and their activity in roots measured.

“…The papers by Gray et al (2013) and Vandergeer et al (2013) in this volume emphasise the below ground processes and acquisition side of the equation, which are still considerably less explored than above ground plant functions. Plants appear to be able to capitalise on higher atmospheric CO 2 so long as they have access to adequate N, underlining the importance of nitrogen use efficiency in crops (Reich and Hobbie 2012).…”

“…Moreover, the increased severity and duration of heat waves, coupled with higher evapotranspiration, are likely to decrease soil moisture. In a study relevant to these probable scenarios, Dias de Oliveira et al (2013) Vandergeer et al (2013) showed that cassava yields and quality are sensitive to drought.…”

“…Maintaining and improving the quality of food is also essential. Consideration needs to be given to the impact of elevated [CO 2 ] and climate change on protein (Högy et al 2009), micronutrients and toxic secondary metabolites such as cyanogenic glucosides (Vandergeer et al 2013). Johnson (2013) in this volume reviews current research aimed at increasing Fe concentrations in (mainly rice) grain, which could significantly improve nutritional quality and health outcomes for large human populations.…”

Abstract. The papers in this special issue were mainly derived from sessions at the International Botanical Congress in July 2011 in Melbourne, and at the ComBio meeting in Cairns, September 2011. They make contributions towards one of the most burning issues we face today: increasing sustainable crop production to provide sufficient high quality food to feed an ever increasing global human population, all in the face of climate change. Plant and crop science will have a major part in ensuring that agricultural production can meet these multiple demands. Contributions in this volume go beyond raising issues and highlighting potential effects of climate change factors, but also point out ways to better adapt to the inevitable.

“…The concentration of CG is dependent on cultivar, growth conditions, farming practices and age of plant (Butler et al, 1973;McMahon et al, 1995). Vandegeer et al (2013) reported that water deficit resulted in a 3 to 4 folds increase of CG concentration in young leaves and tubers respectively. Butler et al (1973) concluded that altering farming practices to reduce cyanide levels was not practical as most cassava farming systems do not possess irrigation or machinery, further suggesting that selective breeding for cultivars with reduced production of cyanide compounds was more feasible.…”

Mineral nutrient calibration for Cassava (Manihot esculenta Crantz) grown in dry-tropical North-Eastern Queensland, Australia: with a focus on Phosphorus and Boron

Cassava (Manihot esculenta Crantz) is a common food crop grown in the tropical and subtropical regions of Asia, South-America and Africa due to the high tolerance of nutrient limitations and abiotic stresses. Recently, renewed interests in cassava as a source of industrial production of textile materials and gluten-free food raise the needs for large-scale commercial production with advanced, sustainable management. To satisfy its regions starch demand, a Korean company Cheil Jedang (CJ) began cassava farming in the Burdekin area, north-east Queensland, Australia by converting grazing land into an intensive, irrigated cassava farm. Proper fertiliser management is known to result in high starch production; however, no previous calibration work has been conducted in the Burdekin region for the production of cassava. A scoping survey had identified five main soil subgroups on the property of CJ: 1B and 1D (Vertosols, cracking clays), 2A and 2C (Sodosols, sodic duplex soils) and 3B (Chromosol, non-sodic duplex soil). The objectives of this study were to determine potential mineral nutrient limitations to crop growth on selected soils using soil ii | P a g e was possible to control soil solution B at a lower rooting density using the current technique.Modifications were recommended for the objective to be achieved. Overall, this study demonstrated the needs of calibration for soil chemical analysis with the better understanding of factors that contribute to its limitation.iii | P a g e
