“…The gross input of carbon by the sugarcane crop was estimated to be 11.7-12.4 t ha -1 year -1 ). Trash is a useful source of plant nutrients and contains 0.42% N, 0.15% P and 0.57% K besides 26, 2045, 236 and 17 ppm of Zn, Fe, Mn and Cu, respectively (Yadav et al 1987). At many places, farmers prefer to burn the trash before harvest for convenience and even after harvest due to handling difficulties and its decomposition is not as easy as that of other crop residues.…”

“…A saving of 75 kg N ha -1 may be obtained by the integrated use of 5 t of cane trash with 75 kg N ha -1 in the sub-tropics (Yadav et al 1987) and with 175 kg N ha -1 in the tropics (Shinde et al 1984). In a multiple ratooning system, keeping trash in furrows and pocket manuring using crow bar was found to be a better technique of trash and fertilizer management with higher benefit:cost ratio.…”

Integrated Nutrient Management in Sugarcane

Integrated nutrient management holds great promise in meeting the growing nutrient demands of intensive sugarcane agriculture and maintaining productivity at higher levels with overall improvement in the quality of resource base. It helps to improve and sustain soil fertility and provides a sound basis for crop production systems to meet the changing needs. Balanced use of organic, inorganic and biofertilizers is essential to maintain a good soil physical and chemical environment and also serve as energy source for the soil microbial biomass. Sugar productivity can be sustained by replenishing the nutrients removed by crops through proper recycling of crop residues and factory wastes along with biofertilizers. As organic manures often leave profound residual effect, recommendations need to be made on cropping system basis.

“…The low contribution of the sugarcane straw to the potassium concentration may result from the relatively short incubation period (60 days) of the plant material, combined with the fact that microbial activity was not favored under the laboratory conditions because of the controlled factors, including temperature and irrigation, which were lower than in the field, thus preventing the full release of potassium. Yaday et al (1987) reported that sugarcane straw incubated at 28 °C released 35% of the potassium in the first 15 days of incubation and that only 70% of all of the total K contained in this crop residue had been released at the end of the experimental period (120 days). Oliveira et al (2003) observed that after a long period of time, the dry matter yield, ranging from 15.6 to 18.5 t, had a mean K accumulation of 130 kg per hectare.…”

Changes in soil chemical reactions in response to straw sugar cane and vinasse

Sugarcane harvesting is predominantly mechanical because of environmental restrictions, reduced requirements for manpower, and the quest for improved efficiency. Therefore, large amounts of straw remain available in the soil. Vinasse, a liquid waste, is a main byproduct of the sugar and alcohol industry, in addition to sugarcane straw. Both accumulate in sugarcane fields; however, the effects of their interaction are unclear. In this study, the effects of applications of sugarcane straw and vinasse on the pH and the potassium (K), calcium (Ca), and magnesium (Mg) concentrations of a dystroferric sugarcane straw and incubated for 60 days. Following the analysis, by layer, the data were subjected to analysis of variance by partitioning the degrees of freedom into orthogonal polynomials. The pH and the Ca, Mg, and K concentrations increased throughout the soil profile upon vinasse application. An acid-base imbalance was observed in the topsoil layers in association with the high K saturation. The application of sugarcane straw enhanced the effects of the vinasse across all of the depths analyzed but did not increase the pH. The best results were obtained when applying a dose of 300 m 3 ha -1 vinasse and 6 t ha -1 sugarcane straw.

Somada à palha, a vinhaça é o principal resíduo líquido da indústria sucroalcooleira. Ambos são depositados a campo; porém, o efeito da interação entre os mesmos, ainda não está esclarecido. Avaliouse a influência da aplicação de palha de cana-de-açúcar e vinhaça no pH e nos teores de potássio (K), cálcio (Ca) e magnésio (Mg) em Nitossolo Vermelho distroférrico de alta saturação por bases. Em 64 colunas de PVC de 0,036 × 0,30 m (diâmetro × altura) foram reproduzidos perfis do solo coletados nas profundidades 0-0.05, 0.05-0.10, 0.10-0.20 e 0.20-0,30 m, em área de cultivo. Os solos foram tratados com vinhaça, em doses equivalentes a 0, 125, 250 e 500 m 3 ha -1 e 0, 3, 6 e 9 t ha -1 de palha de cana-deaçúcar e submetidos à incubação por 60 dias.

“…Sometimes the leaves are instead stripped from the stalks, often cut into small pieces and left as a 15-20-metric ton/ha mat of "greenchop" covering the soil surface [137] 8-10 cm deep [37,138]. While greenchop mulch has been reported to improve sugarcane yield [139][140][141][142][143], it can also immobilize N and P [144,145], inhibit uptake of soil N under certain conditions [146,147], and, presumably because of the induced stress, reduce tillering [148] and yield [149]. Planting season sugarcane stalks harvested in the Lower Rio Grande Valley had 2.3-and 2.8-fold more E. loftini entry holes per stalk in field plots where greenchop was left on the soil surface as a mulch and where greenchop was mechanically incorporated 20 cm into the soil, respectively, than in plots without greenchop [150].…”

Selected Abiotic and Biotic Environmental Stress Factors Affecting Two Economically Important Sugarcane Stalk Boring Pests in the United States

Sugarcane, Saccharum spp., in the United States is attacked by a number of different arthropod pests. The most serious among those pests are two stalk boring moths in the Family Crambidae: the sugarcane borer, Diatraea saccharalis (F.), and the Mexican rice borer, Eoreuma loftini (Dyar). The two species are affected by abiotic and biotic environmental stress factors. Water deficit and excessive soil nitrogen alter physical and physiochemical aspects of the sugarcane plant that make the crop increasingly vulnerable to E. loftini. Weed growth can be competitive with sugarcane but it also supports enhanced abundances and diversity of natural enemies that can suppress infestations of D. saccharalis. In an instance where the stalk borer is considered a stress factor, proximity of vulnerable crops to sugarcane can influence levels of E. loftini infestation of sugarcane. The adverse effects of each stress factor, in terms of stalk borer attack, can be reduced by adopting appropriate cultural practices, such as adequate irrigation, judicious use of nitrogen fertilizer, using noncompetitive weed growth, and not planting vulnerable crops near sugarcane fields. Understanding the relationships between stress factors and crop pests can provide valuable insights for plant breeders and tools for incorporation into integrated pest management strategies.
