“…However, in order to reach this stage, the sowing of summer corn must often be delayed, which can reduce the biomass yield between 10 and 20%, raising questions about the feasibility of this management. With the advancement of maturity, there is a reduction in the quality of the fiber fraction, either by the loss in the participation of leaves or by the greater thickening and lignification of the cell wall (Leão et al, 2016).…”

The goal of this study was to evaluate the effects of successive harvests, with or without application of foliar fungicide, on the morphometric characteristics, yield and nutritional value of rye forage harvested at the hard dough grain stage, aiming at silage production. The preventive control of foliar diseases was carried out with the fungicide OrkestraTM SC®, in a single application, at early flowering, for both harvesting systems. The first harvest was conducted at the full vegetative stage and the second, at the hard dough grain stage. The system with two harvests resulted in higher cumulative yield compared with the single-harvest system (40,680 and 9,029 kg ha-1 fresh and dry biomass with two harvests, against 8,816 and 5,375 kg ha-1 fresh and dry biomass). Fungicide application promoted a reduction in neutral detergent fiber content in both systems, with values of 753.9 against 790.6 g kg-1 for the single-harvest system and 734.4 against 773.3 g kg-1 for the two-harvest system, with and without fungicide, respectively. For lignin content, the application of the fungicide reduced values (97.2 against 110.3 g kg-1) only in the two-harvest system. Rye management with a harvest at the vegetative stage increases the cumulative dry biomass yield without negatively affecting the harvest yield at the hard dough grain stage, and without drastic changes in the nutritional value of the plant. Even under adverse conditions, fungicide application positively interferes with plant cell wall components

This study aimed to evaluate the forage yield, morphology, and nutritional value of three winter cereal wheat (Triticum aestivum cv. BRS Umbu), white oats (Avena sativa cv. URS Guará), and black oats (Avena strigosa cv. Embrapa 139), harvested in two successive cuts, at the vegetative and full vegetative stages, applied or not with fungicide pyraclostrobin. Pyraclostrobin was sprayed two times during the vegetative stage, the first application at the phenological stage V5, and the second, 12 days after the first cut of each forage species. In general, the application of pyraclostrobin resulted in an increase in the participation of leaves in the plant structure, from 72.2% to 86.9% in the second cut; and crude protein increased, and lignin decreased (from 22.75% and 9.89% to 25.60% and 6.30%, respectively) in the first cut and (from 20.82% and 11.73% to 22.28% and 9.20%, respectively) in the second cut. Black and white oats had a higher cumulative biomass production, 3,698 kg ha-1, and 3,277kg ha-1, respectively, and white oats had the lowest content of acid detergent fiber (27.90%) at the second cut.
