“…Irrigation management strategies with controlled water deficit, without compromising the crop yield, can save water, energy, and labor, avoiding wasting water, which is a highly limiting and costly factor in the semiarid region (OLIVEIRA et al, 2016a). Thus, information on the effects of water deficit on the physiology of this crop is essential for an irrigation management capable of increasing water use efficiency (AZEVEDO et al, 2011).…”

“…Water deficits during the sugarcane crop cycle were studied by several authors using different irrigation depths, showing positive trends for the plant morphophysiological and productive parameters with increasing water availability (MAURI, 2012;PEDROZO et al, 2015). However, some cultivars respond differently, with greater development and productivity when subjected to irrigation depths lower than 100% of evapotranspiration (RODOLFO JÚNIOR et al, 2016;OLIVEIRA et al, 2016a). Controlled water deficit is one of the strategies used in irrigated crops to improve and synchronize some physiological stages and, consequently, to achieve greater yields.…”

Sugarcane is one of the most affected crops by water scarcity. The efficient use of the irrigation water is an alternative to minimize this problem. The objective of this work was to evaluate biometric parameters, yield, and technological quality of sugarcane plants subjected to different controlled water deficit regimes in the sub-middle São Francisco Valley, Brazil. The experiment was conducted in a randomized block design, in two crop cycles, with three replications, with ten treatments consisted of three controlled water deficits (15%, 30%, and 45% of the crop evapotranspiration - ETc), applied at three development stages of the plant - sprouting and tillering (Stage I), grand growth (Stage II), and maturation (Stage III) - and a control with 100% of the ETc throughout the entire crop cycle. The controlled water deficit did not affect the technological quality of the sugarcane in any development stage. The sugarcane yield was higher when using a controlled water deficit of 30% of ETc in the sprouting and tillering stages of the plants. The water deficit of 15% of ETc is recommended for the grand growth, or maturation stages of the sugarcane plants for a greater water use efficiency of the production system.

“…Organomineral fertilizers based on sanitized sewage sludge can replace the mineral fertilization efficiently on maize [46] and sorghum [47] while improving soil fertility even in reduced doses and without heavy metal contamination. In soybean, reduced doses (25% less compared to mineral fertilizer) of pelletized organomineral fertilizer formulated with sanitized sewage sludge or sugarcane filter cake resulted in increments in plant height and stem diameter [9; 48].…”

Sugarcane is one of the major alternatives for the biofuel sector and its large production has considerable environmental impacts. Organomineral fertilizers formulated with environmental liabilities such as filter cake and sewage sludge positively affect parameters of plant growth and development. The objective of this study was to evaluate the chemical and technological characteristics of sugarcane fertilized with pelletized organomineral fertilizers based on filter cake and sewage sludge. Eight field treatments were studied, being three levels of organomineral (50, 100, 150%) of two organic matter sources (filter cake, sewage sludge), plus a control with 100% of the recommended fertilization via mineral fertilizer and no fertilization control (0%). Sugarcane was evaluated during two consecutive harvest, and the amount of stalks per hectare (ton ha−1), the sugarcane productivity (ton ha−1), the quantity of sugar per hectare (TSH, ton ha−1), and the chemical and technological analysis of the sugarcane juice: pol (%), brix (%), purity (%) and fiber (%) were evaluated. None of the organomineral sources or doses differed from the exclusive mineral fertilization. The analysis of both harvests indicated that the first cut was the most productive since the responses of the first harvest were superior or similar to the second harvest. The recommended organomineral dose to obtaining maximum quantitative and qualitative sugarcane results was between 102 and 109% of the regular recommendation for mineral fertilization, regardless of the organic source in the first sugarcane harvest. In the second sugarcane harvest, sewage sludge source increase by 4.68 and 4.19% the total amount of sugar per hectare and the quantity of sugarcane compared to the sugarcane filter cake source. Sewage sludge and sugarcane filter cake as sources for organominerals are viable alternatives and advantageous in economic and environmental terms for the cultivation of sugarcane.

“…L.) is an important product of Brazilian agriculture, being considered one of the main alternatives for biofuel production, and its production was 633.26 million tons in the 2017/18 season, which represents a 3.6% reduction compared to the previous season. Sugarcane cultivation in the northeastern region of Brazil has been carried out since the colonial period, particularly concentrated in the coastal and Agreste regions of the states of Alagoas, Pernambuco and Paraíba (Conab, 2017;Oliveira et al, 2016).…”

Sugarcane is considered one of the main alternatives for biofuel production and an important product of Brazilian agriculture, so it is indispensable to adopt new techniques for its cultivation and management. Thus, the present study aimed to evaluate the effect of the quality of supplemental lighting, based on light-emitting diode (LED), on the acclimation of pre-sprouted sugarcane seedlings in a protected environment. The experimental design was completely randomized, consisting of three supplemental LED lighting systems, with light proportions of 90% red + 10% blue (R:B 90/10), 80% red + 20% blue (R:B 80/20) and 70% red + 30% blue (R:B 70/30), and a control, with natural solar radiation, with 5 replicates. Multivariate principal component analysis was used based on the matrix of correlation between all variables (meteorological, physiological and biometric). It was found that the different LED lighting systems increased the photosynthetically active radiation; however, until 20 days after planting, the seedlings were little influenced by the supplemental lighting systems. At the end of the acclimation period, the R:B 80/20 lighting system was the most associated with the growth and size of sugarcane seedlings.
