Plant nutrition can positively influence quality of seeds by improving plant tolerance to adverse climate. In this context, silicon is currently considered a icronutrient and it is beneficial to plant growth, especially Poaceaes such as white oat and wheat, thereby improving physiological quality of seeds. This study had the objective of evaluating the effects of silicon leaf application on plant tillering, silicon levels and physiological quality of white oat and wheat seeds besides establishing correlations between them. Two experiments were carried out in winter with white oat and wheat. The experimental design was the completely randomized block with eight replications. Treatments consisted of foliar application of silicon (0.8% of soluble silicon, as stabilized orthosilicic acid) and a control (with no application). Silicon levels in leaves were determined at flowering whereas the number of plants and panicles/spikes per area was counted right before harvest. Seed quality was evaluated right after harvest through mass, germination and vigor tests. Data was submitted to variance analysis and means were compared by the Tukey test at a probability level of 5%. Person?s linear correlation test was performed among silicon level in plants, tillering and seed quality data. Silicon leaf application increases root and total length of white oat seedlings as an effect of higher Si level in leaves. Silicon leaf application increases mass of wheat seeds without affecting germination or vigor.

The livestock systems are mostly forage-based and the off-season is the most challenging period of the year in Brazil. Mixed pastures established after cropping soybean can greatly enhance the herbage accumulation in crop-livestock systems. Besides, fertilization is not a common practice during the off-season, although, in the Amazon Biome, there is no temperature or photoperiod restrictions. Our objective was to evaluate the fertilization effect on the mixed of Sorghum bicolor (L). Moench cv. BRS 810 with Urochloa ruziziensis during the off-season in Sinop, MT, Brazil. The experiment was planted after soybean harvest, on 10 Mar. 2020, at the Embrapa Agrossilvipastoril, Sinop, MT, Brazil. The experimental design was a randomized complete block with three fertilizations inputs and three replicates. The thee treatments were 0 (control), 25, and 50 kg/ha of N and K in the form of urea + ammonium sulphate and potassium chloride, which were applied on 2 April. Herbage mass was harvested using three quadrats (0.5 m2) per plot, at 20-cm stubble height, to calculate herbage accumulation (HA). The plots were harvest on 20 Apr. (when the sorghum canopy height was higher than 120 cm), 18 May and 15 June. The fertilization rate did not affect Urochloa ruziziensis HA (3505 kg DM/ha). The Sorghum bicolor HA was the greatest under 25 kg/ha of fertilizer (4870 kg DM/ha), and the control was the least (3435 kg DM/ha). The input of 50 kg/ha of fertilizer was similar to both, averaging 4240 kg DM/ha. The mixed HA (Urochloa ruziziensis + Sorghum bicolor) was similar regardless of the fertilizer input (on average, 7690 kg DM/ha). We concluded that 25 kg/ha of fertilizer increased Sorghum bicolor HA improving the forage budget during the off-season.
