“…Thus, the first goal of the coating process, which is to enhance and modify the shape and density of the seed was reached, what should provide greater accuracy in sowing and in the application of chemicals (Mendonça et al, 2007). However, the use of larger doses of micronutrients ended up being harmful to the increase of the weight of the seeds, because as the doses grew larger, the adhesiveness of the coating material reduced.…”

The objective of this work was to study combinations of high doses of boron (B) and zinc (Zn) in the recoating of perennial soybean seeds, in order to provide these nutrients to the future plants. The physical, physiological and nutritional characteristics of the coated seeds and initial development of plants in a greenhouse were evaluated. Tests carried out in the laboratory were conducted in a completely randomized design, and the experiments completed in a greenhouse were a randomized block design. The coating with the dose 0.8 kg of H 3 BO 3 + 0.8 kg of ZnSO 4. kg-¹ of seeds provides the best quality coating. The combination of B and Zn in seed coating reduces the production of shoot dry matter, while the other treatments do not affect the growth variables of the plants. Plants absorb and accumulate the micronutrients added to the coating of the seeds.

“…Results presented on Table 2, however, show lower moisture contents in the pelleted seed as compared to naked seeds. Mendonça et al (2007) and Conceição et al (2009) achieved similar results and attributed the reduction of moisture content in the pelleted seeds to the increase of the total dry weight what resulted in the apparent reduction of moisture content of the pellets.…”

“…Fragmentation (FR): similar to the work of Mendonça et al (2007), a fragmentation test was performed on three replicates (50 pellets each), which were individually evaluated to verify the physical structure of the pellets, with the aid of a magnifying lens (10 X magnification). The evaluation was carried out by surveying the number of pellets presenting cracks or broken parts and the results were expressed in percentage of fragmented pellets.…”

-The supersweet (Sh 2 ) corn seeds have a thin tegument and an irregular shape, which hinder the sowing procedure. As a function of those factors, the significance of using the pelleting process to improve sowing and standardize the stand of plants in the field without the need of thinning within the row is emphasized. Although this technique has already been known for many years, little has been studied on the effect of such procedure on the plantability and on the moisture content of the supersweet corn seeds. Therefore, this research work aimed at evaluating the effects of pelleting on the moisture content of the seeds along the storing process, on the occurrence of gaps on seed deposition and on the dropping of double seeds, with the aid of a testing seeder. Other physical attributes of seeds and pellets were also evaluated through tests of fragmentation, screen retention, mass of a thousand seeds and apparent volume. Results have shown an increase on the mass and on the volume of the pelleted seeds that presented highly resistance to cracks and breaking. The pelleting was efficient on the reduction of gaps and on the deposition of double seeds at sowing, thus providing highly satisfactory results for these attributes. An increase on the seed moisture content was also observed as a function of storage with a significant reduction on this factor after the pelleting procedure. Results allow concluding that the pelleting process reduces seed moisture content and improves plantability, positively affecting the efficiency of the sowing process.Index terms: Zea mays, seed covering, physical quality, pellets.Plantabilidade e teor de água durante o armazenamento em câmara fria de sementes de milho superdoce (Sh 2 ) peletizadas RESUMO -As sementes de milho superdoce (Sh 2 ) possuem tegumento fino e formato irregular, dificultando a operação de semeadura. Em função disso, surge a possibilidade de utilizar o processo de peletização para facilitar a semeadura e obter estande uniforme sem a necessidade de raleio de plantas. Embora essa técnica seja conhecida há muitos anos, pouco se estudou sobre o efeito desse procedimento na plantabilidade e no teor de água de sementes de milho superdoce. Deste modo, este trabalho teve como objetivo avaliar o efeito da peletização no teor de água ao longo do armazenamento e na ocorrência de falhas e de sementes duplas em semeadora de provas. Foram avaliados também outros atributos físicos das sementes e dos péletes por meio dos testes de fragmentação, retenção de peneiras, massa de mil sementes e volume aparente. Os resultados mostram aumento no massa e no volume das sementes peletizadas, que se mostraram muito resistentes à formação de trincas e quebras. O revestimento foi eficiente na redução das falhas e ocorrência de sementes duplas, proporcionando resultados altamente satisfatórios para esses atributos. Foi observado também aumento do teor de água em função do armazenamento e redução do mesmo após o revestimento. Os resultados permitiram concluir que o revestimento reduz ...

The knowledge about the physical characteristics of seeds, whether coated or not, is essential for the design of machines and equipment. Therefore, the objective of this work was to determine the physical characteristics of colza (Brassica napus L.) seeds coated with bentonite, gypsum and kaolin, treated with fungicide (carboxin + thiram) and aqueous extract of black pepper (Piper nigrum L.). The untreated colza seeds were submitted to the coating process using bentonite, gypsum and kaolin as fillers, and as treatment products were used as fungicide (carboxin + thiram) and an aqueous extract of black pepper which were added to an aqueous solution of 30% PVA glue (cementing mixture). Then the physical characteristics were determined: diameter, number of times increased, porosity, angle of repose, resistance, classification in sieves and weight of one thousand seeds. The experiment was organized in a completely randomized design and arranged in a factorial scheme. The means, when necessary, were compared by the Scott-Knott test. The colza seeds coated with bentonite presented greater diameter, number of times increased, porosity, angle of repose and weight of a thousand seeds, followed by gypsum and kaolin. The treatment products had little influence on the physical characteristics of the coated seeds.
