| Comparison of eri silkworm rearing by using different major food plants, different lines of kesseru(Heteropanaxfragrans); Thai and Indian lines, and cassava Rayong 72 was conducted. The results showed that eri silkworm fed with kesseru leaves and cassava leaves has similar life cycles, 57-73 days and 53-73 days, respectively. Using Indian kesseru, larval (1-5 instar) and adult survival rates were 100%. Cocoon yield obtained from feeding with Rayong 72 was significantly higher (P<0.05) than feeding with both 2 lines of kesseru. However, average yields of fresh cocoon, pupa weight, %cocoon shell, total shell weight and fresh cocoon weight/10,000 larvae derived from cassava feeding were 2.2312 g, 1.9029 g, 14.37%, 9.52 g, and 22.31 kg, respectively, and... |

| Cassava, Manihot esculenta Crantz, represents the main food source for more than one billion people. Cassava's production is affected by several diseases, one of the most serious is cassava bacterial blight (CBB) caused by Xanthomonas axonopodis pv. manihotis (Xam). A quantitative trait loci (QTL) analysis for CBB resistance was performed under natural infection conditions, using a mapping population of 99 full-sibs genotypes highly segregant and a SNP-based high dense genetic map. The phenotypic evaluation was carried out in Puerto López, Meta, Colombia, during the rainy season in 2015. Both resistant and susceptible transgressive segregants were detected in the mapping population. Through a non-parametric interval mapping analysis, two QTL were detected,... |

| The aim of this study was to evaluate the genetic dissimilarity among wild and domesticated species of Manihot for resistance to cassava green mite during the insect life cycle. Nine accessions of wild Manihot species, M. esculenta ssp. flabellifolia, M. esculenta ssp. peruviana, and M. carthaginensis ssp. glaziovii, and two clones of M. esculenta (Cigana Preta and Sacaí) were evaluated under laboratory conditions at 25 ± 1°C, 70 ± 10% RH, and a 12-h photophase. Daily observations during the mite life cycle stages (larva-adult) were recorded. The data were subjected to an analysis of variance, a Scott-Knott test (5%), and Singh criterion, cluster, and principal component analyses. The larval-adult period ranged from 5.53 to 7.01 days: the longest period... |

| In Ghana a lot of products are produced from cassava roots, but processing of most cassava product requires peeling. Cassava peeling in Ghana is a major manual activity, which is time consuming and labour-intensive and hence requires mechanization. About 34% of freshly harvested cassava roots is lost along the food chain and faster processing is necessary to curb this situation. The development of an efficient equipment to help fast-track peeling of cassava root is key. A motorized cassava peeler with four different lining materials (concrete, metal, rubber and wood) was developed and tested with two local cassava varieties (Asi-Abayiwa and Dabon). The batch loading weight, peel removal efficiency, percent flesh loss and peeling capacity of the peeler was... |

| Energy inputs and yield relationship in cassava production was investigated to establish correlation between inputs and output in cassava production in Nigeria. Production data of energy inputs and crop yields were collected from 54 cassava farms in twelve cassava producing villages through site visits, interaction with the farmers and physical measurements for three production seasons (2013-2016). The data were analyzed statistically. Amount of inputs per hectare were calculated and multiplied by coefficients of energy equivalents. Total energy inputs in cassava production in this study was 36,482.8 MJha-1 while average output of cassava tubers was 32, 022.6 kgha-1. Energy use ratio, energy productivity and specific energy of the surveyed farms were 4.9,... |

| Abstract The morphoagronomic characterization of 12 genotypes of M. esculenta was performed during the 2013/2014 and 2014/2015 crop years. The 12 genotypes were planted in a randomized block design, with four replicates per genotype. Number of tuberous roots per plant, weight of tuberous roots, root yield, total plant weight, harvest index, plant height, height of first branch, number of shoots, stem diameter, number of buds, leaf dry weight and petiole length were evaluated. Genotypes “Camuquem” and “Goiás” were the most productive, and “Amarela” and “Gema de Ovo” were the most divergent. Seventy percent of genetic diversity was due to petiole length (22.86%), root yield (19.20%), weight of tuberous roots (14.89%) and number of buds (13.72%). Overall, the... |

| Este trabalho teve por objetivo avaliar o efeito da poda da parte aérea, realizada em três épocas distintas, sobre alguns parâmetros fitotécnicos da mandioca (Manihot esculenta Crantz). Todos os tratamentos foram plantados em outubro de 1991. Em 1992, efetuaram-se as podas da parte aérea em maio, julho e outubro. A testemunha foi conduzida sem poda. Em maio de 1993, todos os tratamentos foram colhidos. As produções da parte aérea na poda, foram alteradas pela quantidade de folhas. As produções fresca e seca das raízes e da parte aérea e o índice de colheita, foram modificados após a poda, em relação ao tratamento sem poda. O stand final e o número de raízes por planta, não foram alterados pela poda. |

| Starch nutritional fractions as well as thermal properties and other analysis are essential for food and industrial application. Cassava bagasse is an important agro-industrial residue and its starch content was evaluated using two alternative methods. Thermal characterization and microscopy analyses helped to understand how hydrolysis digests starchy fraction of cassava bagasse. The melting point of cassava starch occurred at 169.2ºC. Regarding TG analyses, after moisture content, there were observed two main mass losses for all samples. Results suggest hydrolysis carried out using enzyme is less effective in order to convert total starch content in cassava bagasse. However, using sulfuric acid, fibers are affected by analyses conditions. |

| The present work had the objective of evaluating the effect of different line spacing upon some agronomic parameters of cassava (Manihot esculenta Crantz) culture. The experiment was conducted in county of Palotina, in the west region of Paraná State, Brazil. The studied spacing were 0.8, 1.0, 1.4 e 1.6 m between lines and 0.6 m between plants, which rendered population densities of 20,830, 16,660, 13,880, 11,900 and 10,410 plants/ha. For the production of fresh and dry root matter and stem fresh matter, the best space between lines was 1.0 m. The highest number of tuberous roots per plant, obtained with the space of 1.40 m between lines did not guarantee the highest productivity of root matter/ha. The production of the vegetative portion was not... |

| Cassava starch, partially hydrolyzed by fungal á-amylase, was characterized using thermal analysis, light microscopy and X-ray diffraction. Thermal degradation was initiated at lower degradation temperatures after enzymatic treatment and the DSC (Differential scanning calorimetry) analysis showed almost similar range of gelatinization temperature, but the enthalpies of gelatinization were quite increased for the partially hydrolyzed starch granules. The results suggested that the partial degradation of the starch granules was concentrated in the amorphous regions. |
