| Nos últimos anos houve uma notável expansão das áreas de cultivo sob solos arenosos, principalmente nos Estados de Maranhão, Tocantins, Piauí e Bahia, Estados estes que compõem a nova fronteira agrícola no Brasil (Brasil, 2018). Isso foi possível, em partes, pela evolução das práticas de manejo, como o plantio direto (PD) e Integração Lavoura-Pecuária-Floresta (ILPF), que favorecem a maior produção e manutenção da matéria orgânica no solo, propiciando maior disponibilidade de nutrientes e água (Balbino et al., 2012; Gil et al., 2016). Dessa forma, tornou-se possível o uso de solos de textura arenosa que antes eram considerados de pouca relevância em regiões agrícolas, mesmo quando presentes em áreas favoráveis à mecanização, por causa de limitações de... |

| In the current scenario of climate change, sorghum crop has high growth potential, requiring adaptation and selection studies for the various Brazilian production environments. Sorghum is among the most drought-tolerant cereals; however, extended summer can reduce the size and number of grains in the plant, reflecting into poorer yields. Sorghum breeding programs aim to develop hybrids more tolerant to water deficit, to ensure profitable yield even in the face of drought stress. The objective of the present study was to evaluate the effects of water restriction on grain sorghum hybrids in the pre- and post-flowering phases in the Brazilian semiarid. Twenty-five hybrids were evaluated under controlled irrigation conditions in Nova Porteirinha-MG and... |

| ABSTRACT - This study aimed to select grain sorghum R lines based on grain yield and disease traits. The experiment consisted of 360 experimental R lines and two checks cultivars CMSXS180R and 9503062R. The experimental design used was of augmented blocks. The evaluated characteristics were plant height, days to flowering, thousand-grain mass, grain yield, and evaluation of leaf blight (Exserohilum turcicum) and anthracnose (Colletotrichum graminicola). In the analysis of variance, the interaction between Lines and checks was significant for all characteristics evaluated. All traits showed heritability above 70%, except a thousand-grain mass below 60%. In this work, the lines that obtained the best means were L57 and L74, considered earlier, with plant... |

| Forage sorghum presents tall plants, what makes mechanical seed harvesting a difficult task. Plant hormones can reduce plant height and facilitate the harvesting. Thus, the objective of this study was to evaluate the effect of the growth regulator trinexapac-ethyl on plant height and seed yield in forage sorghum. This research was carried out at Embrapa Maize and Sorghum, in two seasons (2017 and 2018), in a randomized complete block design, four replications and three varieties (BRS Ponta Negra, 1141574 and 0947216) under application of Trinexapac-ethyl in two stages of the plant growth (V8, V12, V8 + V12). The characteristics evaluated were: plant height, seed yield and mass of 1000 seeds. The effect of the hormone was significant in both stages of... |
