“…The presence of the sugarcane straw blanket on the soil surface was expected to suppress plant tillering by lowering soil temperatures (Viator et al, 2005; Toppa et al, 2010; Sandhu et al, 2013; Awe et al, 2015; Correa et al, 2017) and acting as a physical barrier to tillering. Previous studies, however, have shown variable plant tillering responses to straw cover.…”

“…Reducing incident light delays sprouting of basal vegetative buds (Toppa et al, 2010). Reducing soil temperature during the winter (Sandhu et al, 2013) and increasing soil moisture in early spring can limit plant growth and reduce stalk yield (Kingston et al, 2005; Viator et al, 2005; Viator and Wang, 2011). 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.…”

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

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.

“…Sugarcane cultivation has caused enormous changes in land use with the removal of tropical forest and other vegetation types (Scherr and Sthapit 2009). Some practices related to sugarcane such as burning bring with them the further decline of air and soil quality and affect the regional climate due to variations of soil temperature (Sandhu et al 2013), which can be reflected for example in the heat flux and moisture transport at this scale. The common practice of sugarcane burning methods, before and after the harvest, is an anthropogenic source of emissions of greenhouse gases (GHG) and aerosol to the atmosphere that may also cause respiratory toxicity (França et al 2012, Mazzoli-Rocha et al 2014.…”

Sugarcane cultivation is an agricultural activity of worldwide importance. This crop has been cultivated in Mexico for centuries, impacting important productive areas like the study region called Huasteca Potosina which is located at the Central-East part of Mexico. The relationship between soil conditions, weather and production per hectare allows identifying the edaphological and climatic conditions (aptitude levels) for cultivating sugarcane in the study area. The objective of this research work is to analyze the relation between the cultivated hectares and production of sugarcane. Likewise, to explain its behavior and interpret the contribution of N and C released to the atmosphere for burning sugar cane in association with events and meteorological parameters involved in the flux of water between soil and atmosphere such as drought, evapotranspiration and rainfall. The methods and indicators for burning waste provided by the Intergovernmental Panel on Climate Change (IPCC), the value of potential evapotranspiration as Thornthwaite and drought severity index were applied in order to understand the correlations between the drought severity index and potential evapotranspiration, and between C and N release and potential rainfall availability. The results show the increment of harvested hectares and the loss of water from the soil by the increase of periods of drought events and evapotranspiration. The volatilized nutrients in soil varied from 1.32 × 10 5 to 2.17 × 10 5 t for C and from 1.32 × 10 3 t to 2.17 × 10 3 t for N during the burning of sugarcane, affecting production levels with values fluctuating between 38 t/ha to 77 t/ha for the term of 1990-2010.
