“…Nxumalo et al (2017) reported that delayed plant emergence and early crop establishment due to straw cover did not affect the final plant population compared with straw removal. In contrast, Campos et al (2010) concluded that raking improved plant tillering and final population compared with no raking (i.e., straw cover), particularly for cooler regions of southeastern Brazil. Our results were similar to those of Campos et al (2010), especially at the cooler Bom Retiro site, where the plant tillering responses were similar between bare soil in the second ratoon.…”

“…Agronomically, a straw blanket may negatively affect plant growth and stalk yield with the magnitude of this effect dependent on site-specific soil and climate conditions (Oliveira et al, 2001;Campos et al, 2010). Reducing incident light delays sprouting of basal vegetative buds (Toppa et al, 2010).…”

“…Sandhu et al (2017) reported negative effects of a straw blanket on plant tillering and leaf area index (LAI) from 120 to 200 d but no effect on final stalk yield and sucrose concentrations under subtropical conditions. In Brazil, studies have shown slow initial crop growth and development in the presence of a straw blanket, especially in cooler areas of the main sugarcane-producing region (Oliveira et al, 2001;Campos et al, 2008;Campos et al, 2010;Landell et al, 2013).…”

Sugarcane Straw Blanket Management Effects on Plant Growth, Development, and Yield in Southeastern Brazil

et al. 2019

In Brazilian sugarcane (Saccharum spp.) production systems, the practice of moving harvesting residue from row to inter‐row positions (i.e., raking) has increased in response to producer concerns over the potential negative effects of sugarcane straw on crop establishment and stalk yield. Despite increasing adoption among sugarcane farmers, the impacts of straw raking practices on plant growth and yield remain unclear. A 2‐yr experiment that included both dry and wet seasons was conducted at two sites in southeastern Brazil to evaluate straw management strategy effects on plant tillering, phytomass accumulation, plant nutritional status, and stalk yield. The experiments were established at the Bom Retiro mill and the Univalem mill. Experimental treatments included raking straw to inter‐rows (raked), total straw removal (bare soil), and no straw removal (straw cover). Raked and bare soil treatments improved plant tillering but did not influence final plant population. Straw management had a slight effect on phytomass accumulation. Reduction of phytomass yield was observed from the first to the second ratoon during both seasons at both sites. At Bom Retiro, phytomass yield decreased 37% for stands established during the dry season and 19% for stands established during the wet season. At Univalem, phytomass yield decreased 20% for stands established during the dry season and 30% for stands established during the wet season. Retaining straw in the field (regardless of treatment) increased leaf tissue P content but not stalk yield. Raking straw from row to inter‐row positions at these locations in southeastern Brazil had no benefit on sugarcane yield but may result in soil compaction and higher production costs over time.

“…Campos et al (2008) avaliaram a influência da palhada sobre o perfilhamento, o acúmulo de biomassa fresca e a produtividade da cana-de-açúcar da variedade SP 832847, e observaram efeitos negativos da palhada, em área total, sobre as três variáveis, com redução de cerca de 10% da produtividade. Resultados semelhantes foram encontrados por Campos (2010), com a variedade RB 855453. Entretanto, Ball-Coelho et al (1993) observaram que a manutenção da palhada sobre o solo causou aumentos de 43% da produção de matéria seca da cana-de-açúcar.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de diferentes quantidades de palhada sobre os índices biométricos e fisiológicos e sobre a produtividade da cana-de-açúcar, no primeiro ciclo de cultivo (cana-planta) da variedade SP 801816. Cinco tratamentos -com 0, 25, 50, 75 e 100% de palhada -foram avaliados aos 60, 180, 270 e 350 dias após o plantio. Determinaram-se os seguintes índices biométricos: área foliar, número de folhas, massa de matéria fresca e número de perfilhos. Os índices fisiológicos foram: índice de área foliar (IAF), taxa de crescimento da cultura (TCC) e taxa de crescimento relativo (TCR). Observou-se efeito significativo da palhada em todas as variáveis. Os tratamentos com 100, 75 e 50% de palhada proporcionaram os maiores valores de IAF, TCC, TCR e número de perfilhos, e os tratamentos com 50 e 75%, as maiores produtividades. A manutenção da palhada em superfície não foi prejudicial ao desenvolvimento da cultura. A retirada total ou a manutenção de 25% da palhada resultaram nas menores produtividades. A retirada de 50% da palhada não causa prejuizos à cultura.Termos para indexação: Saccharum, análise de crescimento, cana crua, produção, resíduo agrícola. Productivity and biometric and physiological indices of sugarcane grown under different amounts of strawAbstract -The objective of this work was to evaluate the effect of different amounts of straw mulch on the biometric and physiological indices and on the yield of the sugarcane variety SP 801816, in the first crop cycle (plant cane). Five treatments -with 0, 25, 50, 75, and 100% straw mulch -were evaluated at 60, 180, 270, and 350 days after planting. The following biometric indices were determined: leaf area, number of leaves, fresh matter weight, and number of tillers. The physiological indices were: leaf area index (LAI), crop growth rate (CGR), and relative growth rate (RGR). A significant effect of straw mulch was observed on all variables. Treatments with 100, 75, and 50% straw provided the highest values for LAI, CGR, RGR, and number of tillers, and the treatments with 50 and 75% straw provided the highest yields. Keeping straw mulch at the soil surface had no effect detrimental to sugarcane development. Total removal or straw kept at 25% resulted in the lowest yields. Removal of 50% straw can be done without harming the crop.
