TL;DR: Among the tropical tuber crops, cassava is regarded as the most sustainable as evident from the results of a long term fertilizer experiment (LTFE) at CTCRI since 1977 as the crop could maintain an average yield of 10-15 t ha-1 without any manures and fertilizers from the same field as mentioned in this paper.
Abstract: Among the tropical tuber crops, cassava is regarded as the most sustainable as evident from the results of a long term fertilizer experiment (LTFE) at CTCRI since 1977 as the crop could maintain an yield of 10-15 t ha-1 without any manures and fertilizers from the same field. The inherent physiological mechanism of the plant to shed its leaves at times of drought coupled with high leaf dry matter production and high leaf nutrient content is directly related to the C sequestration potential and the physio-chemical and biological nutrition of the soil for better tuberization and tuber bulking. The experience over 20 years under LTFE indicated that, through the acquisition of 60.38 ppm of atmospheric CO2, the leaf dry matter production was 3.573 t ha-1, reducing the atmospheric CO2 to 317 ppm, increasing the SOC by 2780 ppm resulting a tuber yield to 26 t ha-1 under the recommended practice. The above potentialities of the cassava crop designate it as a sustainable climate resilient food security crop. These crop specificities need to be exploited to utilize the neglected waste lands to partially meet the rising food demand in addition to combating the current issues of rising atmospheric temperature under global warming.

TL;DR: A major portion of the area under cassava in India is under irrigated Vertisols, and the farmers face a number of soil-related constraints which significantly reduce the tuberous root yield of cassava.
Abstract: A major portion of the area under cassava in India is under irrigated Vertisols, and the farmers face a number of soil-related constraints which significantly reduce the tuberous root yield of cassava. In order to reclaim these arid lands and to increase the yield and profitability of farmers, farmer-friendly technologies have been developed based on field experiments conducted during the past 7 years since 2003. Three different on-farm experiments were conducted to study these problems and to develop a sustainable reclamation strategy. Major components of the technology include adoption of deep tillage with a chisel plough, application of neem cake, application of biofertilizers such as N fixer, P-solubilizing bacteria and AM fungi and biocontrol agents like Trichoderma and Pseudomonas. Besides this, a balanced fertilization schedule based on site-specific nutrient management (SSNM) approach have also been developed to address the problems due to imbalance in nutrient applications by farmers in those arid environments. Studies have shown that these technologies have resulted in significant increase in tuberous root yield and income of farmers besides improving soil health and soil quality.

TL;DR: The accessions TL-3 and Megh-1 (Meghalaya) were found to be far apart from other accessions and can be utilized for further breeding programmes.
Abstract: Principal component and cluster analysis were used to examine diversity among growth traits and yield components of 43 accessions of taro at the Regional Centre of Central Tuber Crops Research Institute, Bhubaneswar, Orissa, India. Principal component analysis identified three vectors with minimal Eigen value criterion, which explained 78% of the variation in the traits. Varimax rotation enabled loading of similar type of variables on a common principal component. The genotypes were further subjected to Hierarchical cluster analysis that resulted in eight clusters containing one to seventeen genotypes. The maximum number of genotypes was included in cluster III. The accessions TL-3 and Megh-1 (Meghalaya) were found to be far apart from other accessions and can be utilized for further breeding programmes.

TL;DR: Suja et al. as mentioned in this paper investigated the effect of organic farming on the soil micro-environmentchanges and microbial count under cassava, which is the third largest source of food carbohydrates in the tropics after rice and maize.
Abstract: Alternative soil management practices like organicfarming assume special significance in the context ofglobal climate change for sustainable and safe foodproduction, protection of environment and humanhealth. Organic farming provides a clean environmentby promoting soil quality and sequestering soil organicC. Cassava (Manihot esculenta Crantz) is an importanttropical tuber crop that plays a significant role in thefood and nutritional security. Cassava is the third largestsource of food carbohydrates in the tropics, after riceand maize. It is grown for its starchy roots, which servesas a staple food and also a raw material for starch, sagoand animal feed industries. It has the potential to producemaximum dry matter and has the ability to adapt to awide range of climate and soil. The favourable impact oforganic farming on growth, yield and soil properties oftuberous vegetables viz., elephant foot yam, tannia andyams has been documented (Suja et al., 2009; 2010;2012a; 2012b; Suja, 2013; Suja and Sreekumar, 2014).However, there is limited information on the effect of alternative management practices like organic farmingon the soil micro-climate (Montanaro et al., 2012). Hence the objective of this study was to investigate theeffect of organic farming on the soil micro-environmentchanges and microbial count under cassava.

TL;DR: The distribution of Sri Lankan cassava mosaic virus (SLCMV) in the buds regenerated from the nodes of stem cuttings varied with different varieties using different diagnostic techniques (ELISA, PCR and NASH) as mentioned in this paper.
Abstract: The distribution of Sri Lankan cassava mosaic virus (SLCMV) in the buds regenerated from the nodes of stem cuttings varied with different varieties Using different diagnostic techniques (ELISA, PCR and NASH), the SLCMV distribution in 8 varieties of cassava viz, Sree Sahya, Sree Prakash, Sree Visakham, Sree Padmanabha, Sree Vijaya, M-4, H-165 and H-226 were diagnosed Top portions (one third of total stem used for planting) of the stems in all the varieties tested had maximum virus accumulation except Sree Padmanabha, which showed high virus accumulation in bottom portion Similar results were obtained from the diagnosis of bark samples of all the varieties with variation in the virus accumulation level
