“…However, the distribution of root length observed in the treatment TWI levels were more homogeneous in the soil profile compared to irrigated treatments, which showed greater root length in the region near the emitter tube (Figure 3). BUSO et al (2009) also observed a decrease in root length as to increase the depth in the soil profile. SANTOS (2010) states that subsurface drip irrigation provides a more homogeneous distribution of roots in the profile, different cultivation without irrigation where there is a predominance of roots in the first layer.…”

Irrigation with domestic sewage effluent (DSE) has been recommended by subsurface dripping, as it can obtain a high rate of irrigation efficiency and faster use of salts in comparison with other irrigation methods. The study aimed at evaluating the area, the length and the effective depth of the root system of sugarcane irrigated with DSE by subsurface drip system and with different irrigation rates at depths of 0. 00-0.20, 0.20-0.40, 0.40-0.60 and 0.60-0.80m. The experiment was carried out in the municipality of Piracicaba, in the state of São Paulo (SP), Brazil, in a sugarcane area irrigated with DSE in a completely randomized blocks set up in furrows, with three replications and four treatments, which are: one area without irrigation (AWI) and three irrigated areas meeting 50% (T50%), 100% (T100%) and 200% (T200%) of the crop's water need between each round of irrigation. T100% and T200% provided smaller areas and lengths of roots in the two deepest layers, as compared to AWI and T50%, which stimulated the development of deeper roots due to the water stress. TWI, T100% and T200% presented 80% of the roots up to a depth of 0.40m and T50% treatment presented 76.43% of roots total. KEYWORDS:Root; water reuse; subsurface drip. DISTRIBUIÇÃO DO SISTEMA RADICULAR DA CANA-DE-AÇÚCAR IRRIGADA COM EFLUENTE DE ESGOTO DOMÉSTICO POR GOTEJAMENTO SUBSUPERFICIAL RESUMO:A irrigação com efluente de esgoto doméstico (EED) tem sido recomendada para aplicação por gotejamento subsuperficial, podendo-se obter elevados índices de eficiência de irrigação e mais rápido aproveitamento dos sais em comparação com outros métodos de irrigação. O trabalho objetivou avaliar a área de raiz, o comprimento e a profundidade efetiva do sistema radicular da cana-de-açúcar irrigada com EED aplicado por gotejamento subsuperficial e com diferentes lâminas de irrigação, nas camadas de solo de 0,00-0,20; 0,20-0,40; 0,40-0,60 e 0,60-0,80 m. O experimento foi realizado em Piracicaba-SP, numa área de cana-de-açúcar irrigada com EED, em um delineamento de blocos casualizados dispostos no esquema de faixas, com três repetições e quatro tratamentos, sendo estes: uma área sem irrigação (TSI) e três áreas irrigadas, atendendo a 50% (T50%), 100% (T100%) e 200% (T200%) da necessidade hídrica da cultura entre cada turno de rega. O T100% e o T200% proporcionaram menores áreas e comprimento de raízes nas duas camadas mais profundas, quando comparados ao TSI e ao T50%, que devido ao estresse hídrico, proporcionado à cultura, estimularam o desenvolvimento de raízes mais profundas. O TSI, T100% e T200% apresentaram 80% das raízes até 0,40 m e, nessa mesma profundidade, o tratamento T50% apresentou 76,43% do total de raízes.

“…The study includes both cane-plant and ratoon cane, between 1997 and 2009: crop coefficients (Kc) were recommended by Allen et al (1998), whose periods were fitted to the developmental stages proposed by Machado et al (2009), and the rooting system effective depth (z) was recommended by Buso et al (2009) (Table 1).…”

Water requirements and restrictions to sugarcane in cane plants and ratoon cane cycles in Southern Brazil

et al. 2020

In a site with a Cfa-type climate in southern Brazil, the water requirements and restrictions for the cultivation of sugar cane (Saccharum spp.), in plant and soca (second cut) were characterized. Water availability was calculated based on the daily water balance and evapotranspiration was estimated using the Penman-Monteith method. The thermal and water requirements of sugarcane were calculated taking as reference the agroecological zoning in the state of Paraná, Brazil. Water requirement index did not show limiting factors for the development of the crop both in plant and soca. Water deficit was the most important agroclimatic risk factor. In Paranavaí-PR, Brazil, sugarcane is a safe crop, with possibilities of saving water in the development stage (phase II), with frequent additional irrigation needs of 508.8 mm/crop cycle for plant and 486.5 mm/sugarcane cycle for soca.

“…After harvest, each plant was separated into stem and top+leaves, which were labeled and placed in an oven at 60°C to obtain the dry weight (Oliveira, 2008). Total leaf area (TLA m 2 ) was determined by measuring from the first to the sixth leaf of eight plants in two linear meters of sampling area in each experimental plot, measuring leaf length and width in the middle portion with a graduated ruler, using the equation TLA=L.W.c proposed by Buso et al (2009), where L= length; W= width; c=correction factor. Biometric data were collected to determine parameters related to plant production following the method proposed by Barbosa (2005), where the number of plants was obtained by counting the plants sampled in two linear meters of each plot, and mean stem height was measured with a graduated ruler, measuring plant height from ground level to the top.…”

The great expansion of sugar cane production to non-traditional regions in Brazil has demonstrated the importance of knowledge on the growth characteristics to maintain the productivity and sustainability of the sector. Among the alternatives available to evaluate different varieties of sugar cane, the growth analysis has been one of the most used tools. The objective of this study was to evaluate the growth and development of three varieties of sugar cane for the Pre-Amazon region of Brazil. The varieties used were RB 867515, RB 863129 and RB 92579, and the following parameters of growth were evaluated: accumulation of biomass on the part area, leaf area, number of plants, height of stems, the nitrogen content in different parts of the plant (stem and leaf +3), brix and productivity. For that, samples were collected at 60, 120, 180, 240 and 300 days after planting. For all collecting dates and at 300 days after planting the variety RB 863129 presented better results (P<0.05) for plant height, stem dry weight, N content in leaf +3 and final yield compared to the varieties RB92579 and RB 867515. There was no difference for number of plants (P>0.05) for the varieties RB 863129 and RB 92579. Leaf area was greater (P<0.05) for the variety RB 867515; and nitrogen content of stems were greater for the variety RB 92579 at 300 days after planting. Overall, the RB 863129 variety was the most promising for cultivation in this region during the sugarcane-plant season.
