How to improve early development in wheat

The use of Pack Seed nutritional complex, via seed treatment, improved germination, emergence and initial root development in the wheat.

In Brazil, wheat cultivation (Triticum aestivum) occupies an area of ​​2,5 million hectares for a production of 7,6 million tons. Grain crops sown in Brazil use chemically treated seeds. The application of sprays based on mixtures of fungicides, insecticides, inoculants and bioregulators has demonstrated satisfactory results in the physiological quality of seeds and crop yield.

The application of nutrients via seed treatment is an excellent alternative, due to the direct contact of the product with the seed, which allows the use of smaller doses and better physiological potential of the seeds. Similar behavior is observed when polynutrient nutritional complexes, such as Pack Seed, are added to the chemical treatment. In this scenario, in order to reduce the number of products applied pre-sowing, Spraytec innovated and developed the Pack Seed, a product that combines several elements to compose a single formulation, capable of being applied via seeds, in the furrow and on the leaves.

Pack Seed is a complex mixture of compounds of different biochemical nature and 100% biodegradable for seed treatment. It is a differentiated product, as in addition to the traditional Co and Mo, it provides mineral macro and micronutrients, biostimulants, amino acids, rooting agents, organic acids and microorganisms. It is a complete formulation for seed treatment, and a promising alternative in industrial or on-farm treatment, applied alone or together with other products. The use of cultivars with high genetic potential associated with sustainable development requires innovative and disruptive products such as Pack Seed.

Goal

The present work aimed to evaluate the effectiveness of the Pack Seed product, applied via treatment of wheat seeds, on the physiological quality parameters of the seeds.

Material and methods

The work was conducted at the Center for Applied Agricultural Research at the State University of Maringá, in the municipality of Maringá, Paraná. Wheat seeds from the TBIO Toruk cultivar (Biotrigo) were used. The experiment was installed adopting a completely randomized experimental design for laboratory tests and randomized blocks for emergency tests in the field and in sand, with eight replications. The treatments consisted of absence (standard) and presence (Pack Seed), that is, 0ml and 300ml/100kg of seeds. The evaluation of the physiological potential of wheat seeds was carried out using standard germination tests, first germination count (indicative of vigor), seedling dry mass (aerial part, radicle and seedling), accelerated aging, seedling emergence in substrate sand and seedling emergence in the field. The collected data were subjected to analysis of variance (p < 0,05) and, when significant, the means were compared using the Tukey test, using the Sisvar statistical analysis system.

Results

Comparing the pairs of treatments without and with the presence of Pack Seed, it was noted that the addition of Pack Seed provided better results than those observed in treatments in which the product was not added. Pack Seed's innovative formulation contains substances that can provide a phytonic effect on the physiological performance of wheat seeds. For all variables analyzed, the use of the Pack Seed product ensured superior results to those observed in treatments carried out without the use of the product. Differences were observed between the means of the analyzed variables, in which the treated seeds presented better performance for the first count (PC), germination (G) and accelerated aging (EA) evaluations. This fact occurred due to the seeds showing greater speed in metabolic processes, providing faster and more uniform emission from the primary root in the germination process and a higher growth rate, producing seedlings with a larger initial size. Pack Seed treatment improved seed performance. Regarding emergence in sand and in the field, treating wheat seeds with Pack Seed provided the best results (Figure 1). Analyzing the results, it is noted that for the variables aerial part dry mass (MSPA), root system dry mass (MSSR) and total seedling dry mass (MSTP), the application of the Pack Seed product provided better initial development, indicating the effectiveness of the product in increasing wheat seed performance and seedling development (Figure 2).

Conclusion

The results achieved in the present trial showed that the best results in germination and physiological potential of wheat seeds were obtained using a dose of 300ml/100kg of Pack Seed seeds. The use of the Pack Seed product to treat wheat seeds improved the performance of the seeds in different tests, without causing symptoms of phytotoxicity.
