Resumo: | The search for renewable energy sources coupled with the need to reduce pollution drives the ethanol production. In this scenario, the sweet sorghum culture has been gaining notoriety for filling the sugarcane off-season, having good biomass production, stalks rich in fermentable sugars and a short cycle. However, the high size of the plants makes the crop susceptible to lodging, representing difficulties in harvesting and possible reduction in production. In this way, the aim of the present study was to evaluate the responses of the broth production, it’s quality, the plant morphology and lodging of sweet sorghum, cultivars BRS 511 e BRS 506, on different doses (0,75 L ha-¹ e 1,5 L ha-¹) and application times (Vegetative 5 e Vegetative 8) of the active principle trinexapac-ethyl, in order to identify the correct dosage and application season that reduces crop lodging, without significant losses in total production and quality of the broth produced. In addition, sought to understand the correlations between the morphological variables. Three trials were carried out in the city of Santa Maria - RS on the crop years of 2018/2019, 2019/2020 e 2020/2021. The analyzed variables were: total broth production (PC), soluble solids content (SS), plant height (ALT), stem diameter (DC), leaf dry matter (MSF), panicle dry matter (MSP), stem dry matter (MSC) and lodging. The data obtained were submitted to the Shapiro-Wilk test, test F and test T de Student with 5% probability, the correlation coefficients between the morphological variables were also estimated through the Pearson correlation. The application of trinexapac-ethyl with the tested dosages reduces the vegetative development of the plants, decreasing lodging and maximizing the soluble solids content of the broth, however it results in a significant drop in the total amount of broth produced, regardless of application season and grow crops. Furthermore, there is significant positive linear correlation of high magnitude among the morphological variables ALT, MSF e MSC. |

Nesse cenário, a cultura do sorgo sacarino vem ganhando notoriedade por preencher a entressafra da cana-de-açúcar, ter boa produção de biomassa, colmos ricos em açúcares fermentescíveis e ciclo curto. Entretanto, o elevado porte das plantas torna a cultura suscetível ao acamamento, representando dificuldades na colheita e possível redução na produção. Dessa forma, o objetivo do presente estudo foi avaliar as respostas na qualidade e na produção total de caldo do sorgo sacarino, cultivares BRS 511 e BRS 506, em diferentes dosagens (0,75 L ha-¹ e 1,5 L ha-¹) e épocas de aplicação (vegetativo 5 e vegetativo 8) do principio ativo trinexapac-ethyl, afim de identificar a dosagem e época correta de aplicação que reduza o acamamento de plantas, sem perdas significativas na produção total e qualidade do caldo produzido. Além disso buscou-se compreender o comportamento e as correlações entre as variáveis morfológicas nas dosagens, épocas e cultivares. Foram realizados três ensaios na cidade de Santa Maria – RS nos anos agrícolas 2018/2019, 2019/2020 e 2020/2021. As variáveis analisadas foram: produção total de caldo (PC), teor de sólidos solúveis (SS), altura de planta (ALT), diâmetro de colmo (DC), massa seca de folha (MSF), massa seca de panícula (MSP), massa seca de colmo (MSC) e acamamento. Os dados obtidos foram submetidos ao teste de Shapiro-Wilk, teste F e teste T de Student a 5% de probabilidade, também foram estimados os coeficientes de correlação entre as variáveis morfológicas, através da correlação de Pearson. A aplicação do trinexapac-ethyl nas dosagens testadas reduziu o desenvolvimento vegetativo das plantas, diminuindo o acamamento e maximizando o teor de sólidos solúveis do caldo, entretanto resultou em queda significativa na quantidade total de caldo produzida, independentemente da época de aplicação e cultivar. Ademais, existiu correlação linear positiva significativa de alta magnitude entre as variáveis morfológicas ALT, MSF e MSC.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em AgronomiaUFSMBrasilAgronomiaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessSorghum bicolor (L.)

In this scenario, the sweet sorghum culture has been gaining notoriety for filling the sugarcane off-season, having good biomass production, stalks rich in fermentable sugars and a short cycle. However, the high size of the plants makes the crop susceptible to lodging, representing difficulties in harvesting and possible reduction in production. In this way, the aim of the present study was to evaluate the responses of the broth production, it’s quality, the plant morphology and lodging of sweet sorghum, cultivars BRS 511 e BRS 506, on different doses (0,75 L ha-¹ e 1,5 L ha-¹) and application times (Vegetative 5 e Vegetative 8) of the active principle trinexapac-ethyl, in order to identify the correct dosage and application season that reduces crop lodging, without significant losses in total production and quality of the broth produced. In addition, sought to understand the correlations between the morphological variables. Three trials were carried out in the city of Santa Maria - RS on the crop years of 2018/2019, 2019/2020 e 2020/2021. The analyzed variables were: total broth production (PC), soluble solids content (SS), plant height (ALT), stem diameter (DC), leaf dry matter (MSF), panicle dry matter (MSP), stem dry matter (MSC) and lodging. The data obtained were submitted to the Shapiro-Wilk test, test F and test T de Student with 5% probability, the correlation coefficients between the morphological variables were also estimated through the Pearson correlation. The application of trinexapac-ethyl with the tested dosages reduces the vegetative development of the plants, decreasing lodging and maximizing the soluble solids content of the broth, however it results in a significant drop in the total amount of broth produced, regardless of application season and grow crops. Furthermore, there is significant positive linear correlation of high magnitude among the morphological variables ALT, MSF e MSC. |
