“…Additionally, the area presented the uniformity in the environment conditions, with a slowlevelled topography, with no soil variation and soil management. The trial area was divided into two sub-areas, composed by no-tillage and, reduced tillage soil preparation systems, where sugarcane cultivars (RB965902, RB985476, RB966928, RB855156, RB975201, RB975242, RB036066 and RB855536) were manually planted on July 21, 2016, in density of 15 stalks per meter (Arcoverde et al, 2019a;Arcoverde et al, 2019b). For each soil preparation system, the sugarcane cultivars were planted in a completely randomized design, and eight treatments and four replications.…”

“…Each experimental unit contained 5 sugarcane -plants lines of 5 meters length, spaced in 1.50 m (37.5 m 2 ), adding up 32 experimental units per soil preparation system. The fertilizer rate for planting was uniform for the whole experimental area, with application of 0.3 Mg ha -1 of NPK compost in a formulation 10-25-26 (Arcoverde et al, 2019a;Arcoverde et al, 2019b).…”

“…For the soil tillage and furrow opening operations, the New Holland 4x2, 8030 a tractor, 89.79 kW (122 hp) engine, 2200 rpm, 3rd gear reduced, 14.9-58 front tires and rear tires 23.1-30 and, mass of 4.51 Mg was used. For furrows covering and phytosanitary treatment, was used the Massey Fergusson 4x2 TDA tractor, model MF292 engine power 68.74 kW, 2200 rpm, 3rd gear, 7.50-18 front tires and rear 18.4 -34, and mass of 3.40 Mg; and a sprayer KO Crosss 2000, with 9.5-24 tires, 14 m spray boom and, weight of 1.4 Mg (Arcoverde et al, 2019a;Arcoverde et al, 2019b).…”

“…At 100, 125, 150, 215 and 395 days after planting (DAP), we evaluated the crop height, stalks diameter of ten plants from the three central lines of each experimental unit, considering 1.0 m of the ends of each line as border (Arcoverde et al, 2019a;Arcoverde et al, 2019b). The crop height measurements were performed using a graduated tape measure, of 0.1 mm resolution, measuring the distance from the stalks base to the collar (dewlap) of leaf +1, according Abreu et al (2013).…”

This study aims to evaluate the growth and yield of the sugarcane plant cultivars, and their correlation to soil mechanical penetration resistance in a Dystroferric Red Oxisol submitted to reduced tillage and, no-tillage systems. Eight sugarcane plant cultivars (RB965902, RB985476, RB966928, RB855156, RB975201, RB975242, RB036066 and RB855536) were in each soil preparation system, and the trial was conducted in a completely randomized design and eight treatments and four replications. The trial evaluated: number of tillers per meter, stalks height and diameter, and stalks yield and sugar content. Additionally, were evaluated the soil mechanical penetration resistance (PR) and soil moisture. The highest rates of daily elongation, yield of stalks and sugar content were observed under no-tillage, due to the lower soil mechanical penetration resistance and higher soil moisture. The cultivar RB966928 presented higher values for growth, yield of stalks and sugar content, while RB855536 and the medium to late maturity cultivars RB975201, RB975242, RB036066, which had either a lower stalk growth rate or presented lower number at the end of the cycle in both soil tillage.

The area cultivated with sugarcane in Mato Grosso do Sul, Brazil, has increased significantly in recent years, in which to meet the demand of the mills, the use of adapted varieties has proved to be a fundamental strategy, combined with the use of irrigation, especially in periods of water deficit. The study aimed to evaluate the growth and yield of four sugarcane varieties (CTC 4, RB966928, RB975201, and RB92579) in plant cane cultivated with and without irrigation. The experiment was conducted at Embrapa Western Agriculture (Embrapa Agropecuária Oeste) in Dourados, MS, Brazil. A randomized block design arranged in a 2 x 4 factorial scheme with three replications was used. At 90, 150, 210, 270, 330, and 390 days after planting (DAP), stalk height and diameter, leaf area index (LAI), and dry biomass were evaluated. The soil cover percentage (%SC) was determined through aerial images taken with a drone, with evaluations made from planting to the maximum soil cover. Total recoverable sugar (TRS), number of stalks m-1, stalk (STY), and sugar (SGY) yield were evaluated at 390 DAP (harvest). The RB975201 variety has the highest growth in height, stem diameter, and LAI when grown under irrigation or without irrigation, and the CTC 4 variety has the smallest. The irrigated production system increases the growth of stalks, LAI, and degree of soil cover for the sugarcane varieties in plant cane and a greater amount of stems m-1, STY, and SGY, highlighting the varieties RB92579 and RB975201.

Desenvolvimento inicial da cana-soca sob lâminas de irrigação de salvamento

A cana-de-açúcar é um dos principais produtos agrícolas do Brasil, gerando alimento e energia sustentável para o mundo. No estado de Goiás, o déficit hídrico é um dos fatores limitantes do acúmulo de biomassa, devido à baixa umidade do solo durante praticamente todo o outono e o inverno. Objetivou-se com este trabalho avaliar os efeitos de lâminas de irrigação de salvamento no desenvolvimento inicial da cana-soca de sequeiro, durante os primeiros 30 dias. O experimento foi realizado na Fazenda Isaura, pertencente à Usina São Martinho - Unidade Boa Vista, no município de Quirinópolis, GO. A colheita foi finalizada em 18 de setembro de 2019 e a irrigação ocorreu com Lead Time (dias após colheita) de 7 dias, no dia 25 de setembro de 2019. Utilizou-se o delineamento de blocos casualizados arranjado em faixas. Foram utilizadas cinco lâminas de irrigação (20 mm, 30 mm, 40 mm, 50 mm e 60 mm), uma testemunha (sem irrigação) e seis repetições. Foram avaliados os parâmetros biofísicos: número de perfilhos por metro linear, altura das plantas e massa fresca dos perfilhos. O número de perfilhos por metro linear, altura das plantas e massa fresca dos perfilhos responderam ao aumento das lâminas de irrigação, em todos os períodos avaliados após o plantio, sendo o modelo de regressão linear o de melhor ajuste. Desde que não supere a capacidade de armazenamento de água no solo, o aumento da lâmina de água proporciona aumento do perfilhamento, altura média das plantas e massa fresca dos perfilhos da cana-soca. A lâmina de irrigação de salvamento de 60 mm foi a quantidade ótima para potencializar o perfilhamento da cana-soca.
