A expressão do potencial genético da cultura da soja, possui relação direta com a qualidade da operação de semeadura, bem como, a utilização de sementes de elevado vigor e qualidade sanitária. O tratamento fitossanitário de sementes, é uma alternativa utilizada com a finalidade de proteger as sementes e plântulas nos estádios iniciais de desenvolvimento da cultura contra a ação de patógenos causadores de danos. Deste modo, objetivou-se avaliar diferentes métodos e produtos utilizados para o tratamento fitossanitário de sementes de soja, observando o seu efeito no desempenho de um dosador de disco alveolar horizontal. Os fatores observados foram os diferentes métodos de tratamento fitossanitário de sementes em quatro níveis, tratamento em tambor rotativo, adição de polímeros em tratamento industrial, tratamento industrial com adição de grafite e sementes sem adição de produto (testemunha). O segundo fator, foram as diferentes densidades de semeadura em quatro níveis (12, 14, 16, 18 sem m-1). As variáveis analisadas foram os espaçamentos entre sementes, aceitáveis, múltiplos, falhos e precisão. Após a análise e interpretação dos dados concluiu-se que, tanto o lubrificante sólido grafite como também os polímeros de recobrimento, podem ser utilizados sem que ocorra redução da qualidade de distribuição longitudinal de sementes com tratamento fitossanitário.Palavras-chave: densidade de semeadura, dosador de precisão, polímeros adesivos. LONGITUDINAL DISTRIBUTION OF SOYBEAN SEEDS WITH DIFFERENT METHODS OF PHYTOSANITARY TREATMENT BY A HORIZONTAL PERFORATED DISC METER ABSTRACT:The expression of the genetic potential of the soybean crop is directly related to the quality of the sowing operation, as well as the use of high vigor seeds and sanitary quality. Phytosanitary treatment of seeds is an alternative used to protect seeds and seedlings in the early stages of development of the crop against the action of pathogens causing damage. In this way, the objective was to evaluate different methods and products used for the phytosanitary treatment of soybean seeds, observing its effect on the performance of a horizontal disk metering. The factors observed were the different methods of phytosanitary treatment of seeds at four levels, rotary drum treatment, addition of polymers in industrial treatment, industrial treatment with addition of graphite and seeds without addition of product (control). The second factor was the different sowing densities at four levels (12, 14, 16, 18 without m-1). The analyzed variables were seed spacings, acceptable, multiple, fail and precision. After the analysis and interpretation of the data, it was concluded that both the graphite solid lubricant and the coating polymers can be used without reducing the quality of the longitudinal distribution of seeds with phytosanitary treatment.Keywords: seeding density, metering precision, adhesive polymers.

ABSTRACT The correct longitudinal distribution of seeds by the seeder machine is one of the features that most contributes to obtain an adequate plant stand and good crop yield. The objective of this study was to evaluate the longitudinal distribution of corn seeds by seed conductor tube types, combined with a horizontal perforated disc and a pneumatic meter, altering the seeding density rate. The experiment was conducted in a laboratory using a seed meter test bench. Treatments were a combination of two seed meters, six conductor tubes and four peripheral speeds for the meter disc, corresponding to densities of 60, 70, 80 and 90 thousand corn seeds per hectare and were organized in a three-factor scheme with four repetitions. By increasing the seeding rate into the same ground speed, there was a reduction in the percentage of acceptable spacing, this effect being more pronounced when conductor tubes with a small diameter and straight profile were used.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The aim of this work was to correlate macronutrient content of soybean seeds to physiological quality of different cultivars. The work was developed in the Federal University of Pelotas, in the facilities of the Seed Science and Technology Graduate Program. The experimental design was randomized blocks in arranged in four replicates. The following soybean cultivars were used: BMX Apolo RR (12 lots), BMX Ativa RR (13 lots), BMX Energia RR (26 lots), BMX Força RR (24 lots), BMX Impacto RR (35 lots), BMX Magna RR (16 lots), BMX Turbo RR (44 lots), BMX Potência RR (82 lots) and NA 5909 RR (28 lots), with seeds produced in northwest Rio Grande do Sul. The determination of nutritional contents found in plant tissues of soybean seeds, were measured: Nitrogen (N), Phosphorus (P), Potassium (K), Magnesium (Mg), Calcium (Ca), Sulfur (S). The macronutrient contents of the seeds vary according to genetic characteristics of the cultivars, with higher oscillations of nitrogen, phosphorus, magnesium and sulfur contents present in soybean seeds. Potassium and calcium are defined as the most stable nutrients for the cultivars and seed lots analyzed. High concentrations of nitrogen, phosphorus and calcium are determinants for the physiological quality of soybean seeds.

Differences in levels of lignin in the plant between conventional and transgenic cultivars RR has been reported by several authors, however, there are few studies evaluating the influence of spraying of glyphosate on the lignin in the plant and RR soybean seeds. The aim of this study was to evaluate the physiological quality of RR transgenic soybean seeds and the lignin contents of plants sprayed with the herbicide glyphosate. The assays were conducted both in greenhouse and field in the municipality of Lavras, MG, in the agricultural year 2007/08. The experiment was arranged in a splitplot design with four replicates, considering the treatments hand weeding and herbicide glyphosate as plots, and five RR soybean cultivars (BRS 245 RR, BRS 247 RR, Valiosa RR, Silvânia RR and Baliza RR) as splitplots. In the greenhouse, the cultivars tested were BRS 245 RR and Valiosa RR in a randomized block design with four replicates. The sprayings were carried out at stages V3, V7 and early R5 (3L/ha). The 1000 seed weight, mechanical injury, germination and germination velocity index, emergence velocity index, accelerated aging, electrical conductivity and water soaking seed test, lignin content in the seed coat, in the stem and legumes were determined. The spraying of glyphosate herbicide, in greenhouse and field, did not alter the physiological quality of seeds and the lignin contents in the plant.
