“…The common bean (Phaseolus vulgaris L.) is one of the most important legumes for the human diet, due to its high nutritional quality (20-25% protein), vitamins, and minerals (Broughton et al, 2003). Brazil is considered one of the largest producers worldwide of this legume (Zucareli et al 2016). Low inputs requirement, high economic value, and adequate climate conditions enabling production over three growing seasons throughout the year (Aug.-Nov., Dec.-Mar., and Apr.-Jul.).…”

“…A feasible alternative to reduce the yield gap in these areas is the adoption of high quality seeds, which have resulted in good agronomic performance and consequently high yields. High quality seeds possess great genetic, physical, physiological, and sanitary attributes (Zucareli et al, 2016), which helps crops withstand environmental stresses and defend against pests and diseases. Among those attributes, physiological quality is one of the most important and is related to the ability that seeds have in performing vital functions.…”

“…Among those attributes, physiological quality is one of the most important and is related to the ability that seeds have in performing vital functions. Thus, seeds with high physiological quality promote fast germination, uniform emergence, and yielding seedlings with great tolerance to environmental adversity (Marcos Filho, 2005;França Neto et al 2010;Zucareli et al, 2016). In general, physiological attributes of seeds are highly influenced by the environment (i.e., climate conditions) in which the seeds were produced (Zucareli et al, 2016) and by crop management practices, such as the use of cover crops and fertilizers, which may affect the nutritional and sanity status of the parent plant.…”

Several studies have shown that cover crop can increase common bean (Phaseolus vulgaris L.) yield. However, little is known about the influence of cover crop mixtures in association with topdressing N fertilization on common bean seed quality. We, therefore, evaluated the physiological quality of common bean seeds produced under cover crop residues and N fertilized in a no-till farming system. A 5 × 4 factorial experiment (cover crops and N rates) was performed under field conditions in Mato Grosso do Sul, Brazil. Single-specie and cover crops mixtures [pearl millet (Pennisetum glaucum), pearl millet-jack bean (P. glaucum; Canavalia ensiformis), pearl millet-pigeon pea (P. glaucum; Cajanus cajan), pearl millet-sunn hemp (P. glaucum; Crotalaria juncea), and pearll millet-velvet bean (P. glaucum; Mucuna pruriens)] were grown and common bean was planted in succession. Nitrogen fertilizer (50, 100, and 150 kg N ha-1) was topdressed applied to common bean at the V4 stage. At maturity, common bean plants were harvested, and physiological quality of seeds was assessed. The first germination count, final germination, germination speed index, accelerated aging, and N and protein concentration were influenced by cover crop residues and/or N rates (main effect). A cover crop × N rate interaction was observed for seedling dry biomass after germination and accelerated aging. All treatments produced seeds with high physiological quality. Although the cover crops showed variable results, the application of 100 kg N ha-1 in topdressing slightly improved seed quality attributes compared to the other N rate treatments. We conclude that addition of N fertilizer and cover crop treatments does not affect common bean seed quality to a large extent.

“…The use of seeds with high physiological potential is related to their ability to perform vital functions, characterized by longevity, germination, and vigor (Cardoso et al, 2012). However, these characteristics may be influenced by the genotype (Mambrin et al, 2015), environmental conditions of its production and season yields (Zucareli et al, 2016).…”

“…However, in regions with a warmer climate, such as the North of Minas Gerais, for cultivation in drought and winter seasons, there is a greater advantage in cultivation in the harvest of the waters due to the higher temperatures that tend to cause greater abortion of flowers (Didonet & Vitoria, 2006), greater competition with weeds (Barrosos et al, 2010), and the risk of harvesting in the rainy season (Araújo & Camelo, 2015), impairing the production of good quality seeds. Zucareli et al (2016) reported that bean cultivation in the dry season provides seeds with greater germination and vigor compared to the harvest of the waters.…”

ABSTRACT:This work was carried out in order to evaluate the physiological quality of common bean seeds of different types of growth, according to the sowing seasons. The treatments were arranged in 2 x 4 factorial scheme, involving two sowing seasons (dry and winter) and four genotypes (Ouro Vermelho, Ouro Negro, BRSMG Madrepérola e Manteigão Vermelho), in randomized blocks design . The seeds were initially evaluated as for water content, thousand seeds weight and physiological potential by the germination and vigor tests (first germination count, plantlets emergence in sand, emergence speed Index and electrical conductivity). The seeds of the prostrate genotypes, with type of growth III (Ouro Negro and BRSMG Madrepérola) or semiprostate with type of growth II/III (Ouro Vermelho) present better physiological potential, regardless of the sowing season. In the crop of Summer/autumn, the sowing of bean is more suitable for producing seeds with high physiological quality in the conditions of cultivation of the north of Minas Gerais.Key words: crops; germination; Phaseolus vulgaris L.; vigor Época de semeadura e potencial fisiológico de sementes de feijoeiros de diferentes tipos de crescimento RESUMO: O objetivo neste trabalho foi avaliar a qualidade fisiológica de sementes de feijão-comum de diferentes tipos de crescimento, em função das épocas de semeadura. Os tratamentos foram dispostos em esquema fatorial 2 x 4, envolvendo duas épocas de semeadura (seca e inverno) e quatro genótipos (Ouro Vermelho, Ouro Negro, BRSMG Madrepérola e Manteigão Vermelho), em delineamento experimental casualizado em blocos. As sementes foram inicialmente avaliadas quanto ao teor de água, massa de mil sementes e potencial fisiológico pelos testes de germinação e vigor (primeira contagem de germinação, emergência de plântulas em areia, índice de velocidade de emergência e condutividade elétrica). As sementes dos genótipos de porte prostrado, com tipo de crescimento III (Ouro Negro e BRSMG Madrepérola) ou semiprostrado com tipo de crescimento II/ III (Ouro Vermelho) são de melhor potencial fisiológico, independente da época de semeadura. Na safra da seca, a semeadura do feijoeiro é mais adequada para a produção de sementes com elevada qualidade fisiológica nas condições de cultivo do norte de Minas Gerais. Palavras

Evaluation of coatings for application in raffia big bags in conditioned storage of soybean cultivars in seed processing units

et al. 2020

Different regions have different environmental conditions, which may be unfavorable for the preservation of the quality of stored soybean seeds over time. Thus, it is necessary to adopt specific technologies to control the storage environment conditions. Big raffia bags are widely used for the storage of soybean seeds, however these consist of a porous, permeable material that allows the exchange of gases between the packaging and the storage environment. In an effort to find a solution to this problem, in this study we evaluated low cost big bag coating alternatives, in order to minimize the effects of temperature and intergranular humidity on stored seeds. Thus, the aim of this work was to evaluate the quality of soybean cultivars subjected to different temperature and storage duration conditions and stored in raffia bags with or without internal coating. We used a completely randomized, three-factor (10 × 6 × 5) experimental design. We assessed 10 soybean cultivars, six storage environments, and five evaluation periods. Our results showed that seeds of the M-SOY 8866, M7110 IPRO, CD 2737 RR, and BMX DESAFIO 8473 RSF soybean cultivars preserved their physiological quality better in different storage environments. The storage duration had a cumulative effect on the negative factors that favor the deterioration of the quality of the stored seeds. The storage temperature was the main factor that affected the physiological quality of the stored seeds. The use of coated packaging was beneficial in preserving the physiological quality of stored soybean seeds; however, its effect was greater at ambient temperature than in a cold environment. The best storage environment for the preservation of the quality of the seeds was characterized by 10°C temperature conditions and the use of coated packaging, while the worst storage environment was characterized by ambient temperature conditions without the use of coated packaging. Thus, it was concluded that the use of coatings in raffia big bags can be an alternative for maintaining the quality of seeds of different soybean cultivars during storage in seed processing units.
