“…In addition, we can infer over the size of the grain, as well as over its maturity and sanity (Brasil, 2009). In literature, it is reported that the specific mass of the seeds is strongly influenced by the edaphoclimatic conditions and chemical management of the soils (Batistella Filho et al, 2013).…”

ABSTRACT. This study aimed at verifying the adaptability and stability of soybean cultivars, considering the grain yield and quality of seeds, adopting univariate and multivariate approaches. The experiments were conducted in two crops, three environments, in 2013/2014 and 2014/2015 crop seasons, in the county of Inconfidentes, Lavras, and Patos de Minas, in the Minas Gerais State, Brazil. We evaluated 17 commercial soybean cultivars. For adaptability and stability evaluations, the Graphic and GGE biplot methods were employed. Previously, a selection index was estimated based on the sum of the standardized variables (Z index). The data relative to grain yield, mass of one thousand grain, uniformity test (sieve retention), and germination test were standardized (Z ij ) per cultivar. With the sum of Z ij , we obtained the selection index for the four traits evaluated together. In the Graphic method evaluation, cultivars NA 7200 RR and CD 2737 RR presented the highest values for selection index Z. By the GGE biplot method, we verified that cultivar NA 7200 RR presented greater stability in both univariate evaluations, for grain yield, and for selection index Z.

“…Batistella Filho et al (2013), in a study on fertilization with phosphorus and potassium for soybean seeds production and quality, concluded that the phosphate fertilization increases yield and does not affect the physiological quality of soybean seeds produced, even in soils with very little phosphorus available. In its turn, fertilization with potassium does not affect the yield nor alter soybean seeds vigor, but can improve germination in soil with medium levels of this nutrient.…”

Spatial variability in soybean seeds quality and in chemical attributes of the soil of a production field in the Brazilian Cerrado

The objective of this study was to evaluate the spatial variability in soybean seeds quality and in soil chemical attributes of a production field. Data were collected at 138 georeferenced points of a soybean production property located in Santo Antônio de Leverger -MT. Soil related variables, such as phosphorus, potassium, calcium, magnesium, and organic matter (OM) contents, pH, cation exchange capacity (CEC) and base saturation (V%) were evaluated. On the other hand, yield, one thousand seed mass, size, germination, emergence in seedbed, electrical conductivity, accelerated aging and tetrazolium reaction were evaluated as seed variables. The data were submitted to descriptive and geostatistical analysis, and the fit semivariogram parameters were used to elaborate spatial distribution maps of the analyzed variables. After the analysis, it was possible to conclude that there was spatial variability in the evaluated attributes for both seeds and soil related variables, indicating that the soybean seed production area can be divided into management zones, which allows the definition of areas to be harvested or discarded within a field of seed production.

“…Guerra et al (2006) also found that phosphorus applied at the time of sowing increased the vigor, germination, and seedling emergence potential of crops in the field. However, Batistella Filho et al (2013) found that phosphorus fertilization increased the productivity and seed mass for soybean, but did not affect physiological quality. Similar results were observed by Salum et al (2008), who reported that the physiological quality of seeds was favored neither by the phosphorus content in the seed nor its availability in the soil.…”

The use of appropriate management practices, such as sowing and fertilizing, associated with the use of promising genotypes are strategies for obtaining bean seeds of high quality. The aim of this study was to evaluate the physiological quality of cultivars of common bean seeds produced in two growing seasons under different phosphorus levels. The experimental design was completely randomized in a factorial design of 2 × 2 × 6, with four replications. We evaluated two common bean cultivars ('IAC Carioca Precoce' and 'IAC Carioca Tybatã'), two planting seasons of common beans (rainy season and dry season), and six rates of phosphorus fertilization (0, 30, 60, 90, 120, and 150 kg ha -1 of P 2 O 5 ) applied to the planting rows, using triple super phosphate as the source of P. Seed quality was evaluated by testing the water content, germination, first account of the germination test, accelerated aging test and the water content after the test, electrical conductivity, and seedling emergence in the field. Data were subjected to analysis of variance and the means of cultivars and growing seasons were compared using Tukey's test at 5% probability. Regression analysis was performed for phosphorus levels. Seeds of 'IAC Carioca Precoce' produced during the rainy season showed higher germination. In the dry season, the highest seedling emergence in the field was recorded for 'IAC Carioca Tybatã'. Common bean cultivation provided seeds with higher germination and vigor in the dry season than in the rainy season. The accelerated aging test showed that when phosphorus was applied in the planting rows, the vigor of common bean seed was enhanced, with a better response to higher doses when cultivated in the dry season.

ResumoA utilização de práticas de manejo adequadas, como época de semeadura e adubação, associados ao uso de genótipos promissores, são estratégias para a obtenção de sementes de feijão de elevada qualidade. O objetivo do trabalho foi avaliar a qualidade fisiológica de sementes de cultivares de feijão carioca produzidas em duas épocas de cultivo com diferentes doses de fósforo. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 2 × 2 × 6, com quatro repetições. Foram avaliados duas cultivares de feijão carioca ('IAC Carioca Tybatã' e 'IAC Carioca Precoce'), duas épocas de cultivo de feijão (época das águas e da seca) e seis doses de fósforo (0, 30, 60, 90, 120 P 2 O 5 ) aplicadas no sulco de semeadura, utilizando como fonte o superfosfato triplo. A qualidade das sementes foi avaliada pelos seguintes testes: teor de água, germinação e primeira contagem do teste de germinação, envelhecimento acelerado e teor de água após o teste, condutividade elétrica e emergência de plântulas em campo. Os dados foram submetidos à análise de variância e as médias das cultivares e épocas de cultivo comparadas pelo teste de Tukey, a 5% de probabilidade e as doses de fósforo foram analisadas através de regressã...
