“…The lower NPLM, in the conventional cultivation may have helped the plants to present higher growth, reaching higher HPF, consequently, higher HIP, because the small number of plants causes a smaller competition for water and The NDM was lower than those determined by [31] (Table 3) with a cycle varying from 80 to 150 days, these values are dependent on the variety and environmental conditions.…”

The objective of this research was to evaluate the agronomic performance and productivity of sixteen genotypes of Chenopodium quinoa cultivated in agroecological and conventional production systems. The evaluations were carried out, based on agronomic characteristics and yields of sixteen C. quinoa genotypes, grown in two simultaneous experiments, in an agroecological production and a conventional production system carried out at the town of Entre Rios do Oeste, Paraná, Brazil in the harvest 2015/16. Each experiment was composed of three replicates, following the randomized block design. Number of plants in flowering, number of plants per linear meter, height of insertion of the first panicle, number of days for maturation and productivity were the parameters evaluated. The data were submitted to statistical analysis with the aid of the GENES computational application. Genotype Q13-24 showed a more suitable production for the conventional production system. While the genotype Q13-01, presented the increase of productivity, being more indicated to the system of agroecological production. The characteristics height of plant flowers (HPF) and height of insertion of the first panicle (HIP) had higher values when the plants were cultivated in a conventional system. The number of plants per linear meter (NPLM) was higher in the agroecological crop, when compared to conventional cultivation. The same quinoa genotype can behave differently depending on the area management, being a productivity and the genotype cycle depends on the production system and the genotype used.

“…It can be cultivated during the fall season or the off-season (winter) of the soybean and/or corn production in the counties of the Brazilian Cerrado, due to water restriction tolerance, high biomass and short cycle grain production (SPEHAR et al 2003, TEIXEIRA et al 2003. Therefore, it is a crop that should be better used in Brazil, including for soil coverage under no-tillage.…”

Seed germination involves complex physiological and biochemical mechanisms. The cultivation of amaranth, of great food importance, lacks information about this process. The aim of this study was to evaluate the effect of temperature, light and different substrates on the germination of amaranth seeds. The experimental design was entirely randomized in a trifactorial scheme, with two temperatures, two conditions of light and four substrates, with four repetitions of 100 seeds each. The percentage of seed germination was evaluated until 24 days of implementation and the cumulative germination at 07, 14 and 24 days. The germination began on the fourth day for the substrate between sand and for the other substrates it began on the eleventh day, stabilizing in the fourteenth day. There was triple significant interaction among temperature, light condition and substrate factors used on the germination test. The best condition for amaranth seed germination is at a 25 ºC temperature, in the absence of light and on paper roll substrate, with 87% of germination. These conditions can be used in germination tests for seed lots, to test its quality.

“…Por apresentar crescimento rápido e ser capaz de se desenvolver e frutificar em ambientes com luminosidade intensa, alta temperatura e restrição hídrica, o amaranto tornou-se uma ótima opção para cultivo no Cerrado brasileiro (Spehar et al, 2003).…”

“…A literatura apresenta vários métodos de pipocamento de grãos de amaranto, desde o convencional, que usa chapa metálica quente, passando pelo fluxo de ar quente, vapor superaquecido em sistema de leito fluidizado, até o uso de extrusoras adaptadas (Singhal & Kulkarni, 1991;Tovar et al, 1994;Tosi et al, 1996;Tikekar & Karwe, 2009).…”

Resumo -O objetivo deste trabalho foi avaliar a influência do teor de umidade, da temperatura de armazenamento e do momento da hidratação de grãos de amaranto (Amaranthus cruentus L.) sobre sua capacidade de expansão térmica, bem como comparar as composições químicas de grãos crus e pipocados. Os atributos diâmetro médio ponderado, volume de expansão, densidade, rendimento, quantidade descartada e tempo de residência de grãos da variedade BRS Alegria foram avaliados de acordo com três teores de umidade (9,5, 11,5 e 13,5%), duas formas de armazenamento, temperatura ambiente de ±28°C e congelado a -18°C, e dois momentos de hidratação, antes e após congelamento. Utilizou-se chapa metálica aquecida a 215°C para pipocar os grãos. Grãos congelados com umidade de 13,5% tiveram maior diâmetro médio ponderado e volume de expansão, e menor densidade e tempo de residência. A umidade de 13,5% proporcionou os maiores rendimentos e expansão dos grãos. O armazenamento a -18°C produziu pipocas maiores e mais leves do que em condições ambientais. As pipocas apresentaram redução nos teores de proteínas e fibras insolúveis e aumento nos de lipídeos e fibras solúveis, em relação ao grão cru. O congelamento dos grãos a -18ºC e sua hidratação a 13,5% de umidade favorecem o pipocamento de grãos de amaranto, com produção de pipocas de melhor qualidade.Termos para indexação: Amaranthus cruentus, composição química, pipocamento, propriedades físicas. Moisture and freezing of amaranth grains and their thermal expansion capacityAbstract -The objective of this work was to evaluate the influence of moisture content, storage temperature, and moment of hydration of amaranth (Amaranthus cruentus L.) grains on their expansion capacity, as well to compare the chemical compositions of raw and popped grain. The attributes mean weight diameter, volume of expansion, density, yield, amount of non popped grains and residence time of BRS Alegria grains were evaluated according to three grain moisture contents (9.5, 11.5 and 13.5%), two forms of storage, environment temperature (±28°C) and freezing (-18°C), and two different stages of hydration, before and after freezing. A metal plate was heated to 215°C to pop the grains. Frozen grains with 13.5% moisture content had higher average diameter and volume expansion, lower density and residence time. The grain moisture content of 13.5% produced the highest yields and grain expansions. The storage at -18°C provided larger and lighter popping than the environmental one. Popping presented reduced protein and insoluble fibers and increased lipid and soluble fiber in relation to the raw grain. Frozen grains at -18ºC and hydration at 13.5% moisture, favors the popping of amaranth, and results in higher quality of the popped grains.
