PHYLLOCHRON VARIABILITY AND CUTTING MANAGEMENT PRACTICES ON THE AGRONOMIC POTENTIAL OF SORGHUM (Sorghum bicolor (L.) Moench)

et al. 2023

The phyllochron is an indispensable parameter associated with the potential production of sorghum. Accordingly, management practices applied directly in the sorghum (Sorghum bicolor (L.) Moench) crop, such as the cutting technique, provide the ability of plants to regrowth and reestablish the performance of vegetative and reproductive development based on the stimulation of growth in the photosynthetically active area. Appropriately, the aim of this study was to evaluate the alterations in phyllochron and leaf emission rate expressed by the implementation of cutting management practices in sorghum plants from high and low-quality seeds. The study was performed in the experimental and didactic area of the Federal Institute of Rio Grande do Sul (IFRS) – Ibirubá, Rio Grande do Sul, Brazil. The experimental design was completely randomized and the treatments were plants from higher (HQS) and lower (LQS) quality seeds and two season crops (2015/16 and 2016/17) with eight replications. The mean phyllochron (°C day leaf-1), height (cm), main stem diameter (cm), number of nodes, dry mass (kg ha-1), and number of tillers were evaluated as a strategy to verify the performance of each treatment. Furthermore, meteorological data obtained from an automatic station was required to calculate phyllochron and the evapotranspiration (ETc). Finally, this study indicated that the diameter of the stem and tillers is directly associated to the accumulation of a dry mass of the crop, based on the results of biomass productivity. Moreover, it was demonstrated that forage sorghum plants derived from HQS indicated a higher capacity to accumulate photoassimilates, stimulating the production of dry mass.

“…According to SANTOS et al ( 2019), sorghum easily adapts to direct competition with other species. Among physiological responses to competition for light and physical space, stem elongation is one of most known (OLIVEIRA et al, 2020). In the present study, sorghum showed 2.7% increased height and 43.7% decreased stem diameter compared to corn.…”

Urochloabrizantha and corn or sorghum silage integrated production: agronomic evaluation, fermentation losses, and aerobic stability of silage

et al. 2023

The present study evaluated germination, production, and morphological composition of Urochloabrizantha intercropped with corn and sorghum; and silage fermentation losses and aerobic stability of intercrop silage using microbial inoculant. Twenty experimental parcels (5.0 × 3.6 m) were used in a blocked randomized design to evaluate four treatments obtained from a 2 × 2 factorial arrangements: I) crop material (corn vs. sorghum) and II) Brachiaria (U. brizantha) establishment (present vs. absent). Corn- and sorghum-brachiaria integrated systems showed similar brachiaria germination, forage yield, and morphological composition. There was no crop and brachiaria interaction effect on the variables related to corn and sorghum plants and the total productivity. Brachiaria decreased the stem diameter and increased the population of maize and sorghum plants. However, it did not affect systems productivity. Microbial inoculation did not affect corn silage effluent losses and reduced sorghum silage effluent losses. In corn silage, brachiaria did not affect gas losses, while in sorghum silage, brachiaria increased the gas losses. Total losses were higher in sorghum silage than in corn silage, which resulted in a lower DM recovery. The treatments did not affect the pH of the silage after aerobic exposure. However, brachiaria increased silage temperature evaluated at 32 and 40 hours after aerobic exposure. Thus, corn or sorghum consortium has similar brachiaria morphological composition and productivity. Moreover, in intercropped silage, brachiaria increases effluent losses and reduces silage aerobic stability.

“…Importantly, with a dry biomass production of approximately 20,000 kg ha -1 of the grain sorghum hybrid BRS 330, grown after soybean, it represents an exciting option for straw production for the notill system, as highlighted by Rossi et al (2013) for the same locality. Furthermore, sorghum biomass produced after soybean becomes an alternative for animal feed in integrated crop-livestock systems in the Cerrado (Oliveira et al, 2020a(Oliveira et al, , 2020bSantos et al, 2020;Sousa Júnior et al, 2020).…”

The appropriate arrangement of sorghum plants combined with the supply of nutrients increases grain yield. In this context, the objective was to evaluate the agronomic performance of grain sorghum grown under different plant arrangements and nitrogen fertilization levels. Experiments were carried out in Rio Verde and Montividiu in a 3 x 2 factorial randomized completely block design with six replications, with three spacing between rows (reduced, traditional and double row) and the use or not of 90 kg ha-1 topdressing nitrogen. There was a beneficial effect of topdressing nitrogen fertilization on grain yield when sorghum was grown in double rows in both locations, and for the reduced arrangement in Montividiu. However, the effect of topdressing nitrogen fertilization on grain yield in the traditional arrangement was not found. The dry shoot biomass of sorghum plants increased with nitrogen fertilization in Montividiu. The arrangement or topdressing nitrogen fertilization did not influence the thousand-grain weight of Sorghum.
