A pesquisa detalhada sobre a interação entre Crotalaria juncea e cana-de-açúcar revelou benefícios amplos para a sustentabilidade agrícola, incluindo a condição do solo, redução de custos e impactos ambientais positivos. O estudo visou analisar essa interação, compreendendo sua eficácia na promoção da saúde do solo e promover melhores práticas de agricultura. Além disso, examinou os benefícios econômicos, como a diminuição dos gastos com fertilizantes nitrogenados, e identificou modelos econômicos para encorajar os agricultores a adotarem essas práticas. Impactos ambientais favoráveis, como a redução das emissões de gases de efeito estufa e a conservação da biodiversidade. A resistência a pragas e doenças, bem como a redução da dependência de pesticidas na cana-de-açúcar, foram destacadas. Em conclusão, o estudo não só demonstra os benefícios da interação entre Crotalaria juncea e cana-de-açúcar, mas também ressalta a importância de uma abordagem integrada e colaborativa. Essa pesquisa oferece uma contribuição para pesquisadores, agricultores e formuladores de políticas, impulsionando práticas agrícolas mais sustentáveis.

“…The crotalaria juncea and breviflora were the most sensitive to the toxicity of aluminum. Thus, considering both the productivity of crotalaria juncea and the successor crop, usually sugarcane, doses of limestone should be applied to increase saturation by bases to 60%, which will have an impact on the complete neutralization of exchangeable aluminum (ERNANI & ALMEIDA, 1986;RAIJ, 2011;OLIVEIRA et al, 2019).…”

“…Among the main desirable characteristics of a plant to be used as green fertilizer are: the possibility of mechanization from sowing to seed harvesting; the capacity to associate with nitrogen-fixing bacteria in the air; rapid growth to control weeds; having mechanisms, or synthesizing compounds, that help in the control of pests such as nematodes and diseases; the absence of dormant seeds; a vigorous and deep root system that helps in the recycling of nutrients from the deeper layers and in the decompaction of the soil, since the intensive use of the soil with conventional practices, such as excessive mechanization, has reduced the organic matter and caused compaction of those soils. Crotalaria juncea has all the characteristics described above and for this reason has been the green fertilizer preferentially used in the areas of planting or reforming sugarcane, providing excellent agronomic and financial results (OLIVEIRA et al, 2019;2021b;WUTKE et al, 2023).…”

Crotalaria juncea and spectabilis have been widely used in green manuring, mainly due to the fact that they incorporate large amounts of N into the soil, through biological fixation of atmospheric N2, and also because they have a vigorous and branched root system, characteristics that help to recycle nutrients from the deeper layers of the soil. The present work was carried out in the municipality of Mercês, in the Mata Mineira area. Growth rates and nutrient accumulation were evaluated in the aerial part of sunn hemp and sunn hemp, grown in soil with good nutrient availability. The soil in the chosen area had good fertility, with no exchangeable aluminum in the 0 to 20 cm layer. Soon after the first spring rains, the soil was subsoiled, plowed, and harrowed, and the study was then installed, conducted in an experimental design in randomized blocks with five replications. The plots consisted of six furrows of five meters in length with 0.50 meters of spacing. Sowing was carried out in the first week of October. Evaluations of dry matter accumulation and plant height were carried out in the four central furrows of the plots, at 30; 45; 60; 75; 90 and 105 days after emergence (D.A.E.), with a sample area of 1.0 m of furrow (0.5 m2). In the biomass collected at 105 D.A.E, phenological stage of grain filling, the contents of nitrogen, phosphorus, potassium, calcium, magnesium and sulfur were determined, with the objective of quantifying the accumulation of these elements in the aerial part of sunn hemp. The results obtained in this edaphoclimatic environment led to the conclusion that sunn hemp juncea had faster vegetative development than sunn hemp spectabilis, therefore, a plant with greater soil protection potential against the impact of raindrops than sunn hemp spectabilis. Although they have very different growth rates, both for sunn hemp and sunn hemp, the highest rates of growth and dry matter accumulation in the shoots occurred in the periods from 45 to 60 D.A.E., with mean values, respectively, of 406, 7 and 140.0 kg per hectare per day. The accumulation of dry matter in the aerial part, as a function of the age of the plants, can be described by the quadratic equation, y = 0.0024 x2 + 0.5267x -11.8086 (R2= 0.9888), for sunn hemp, and y = 0.0008 x2 + 0.2003x -4.4657 (R2= 0.9928), for sunn hemp spectabilis. For the adopted production system, and in this climatic environment, sunn hemp was a better recycled/fixing plant than sunn hemp spectabilis, thus, green manuring with sunn hemp was more advantageous than with sunn hemp spectabilis.

“…In Brazil, sugarcane plants are mainly planted in two different seasons (January to March or October/November) in South-Eastern Brazil and the cropping season and best suited varieties vary for each [ 6 ]. When planting is carried out between September and early December, the term “one-year” sugarcane is used since the crops are harvested around 12 months after planting.…”

To reduce the potentially irreversible environmental impacts caused by fossil fuels, the use of renewable energy sources must be increased on a global scale. One promising source of biomass and bioenergy is sugarcane. The study of this crop’s development in different planting seasons can aid in successfully cultivating it in global climate change scenarios. The sugarcane variety SP80-3280 was field grown under two planting seasons with different climatic conditions. A systems biology approach was taken to study the changes on physiological, morphological, agrotechnological, transcriptomics, and metabolomics levels in the leaf +1, and immature, intermediate and mature internodes. Most of the variation found within the transcriptomics and metabolomics profiles is attributed to the differences among the distinct tissues. However, the integration of both transcriptomics and metabolomics data highlighted three main metabolic categories as the principal sources of variation across tissues: amino acid metabolism, biosynthesis of secondary metabolites, and xenobiotics biodegradation and metabolism. Differences in ripening and metabolite levels mainly in leaves and mature internodes may reflect the impact of contrasting environmental conditions on sugarcane development. In general, the same metabolites are found in mature internodes from both “one-year” and “one-and-a-half-year sugarcane”, however, some metabolites (i.e., phenylpropanoids with economic value) and natural antisense transcript expression are only detected in the leaves of “one-year” sugarcane.
