Effects of sugarcane residue and green manure practices in sugarcane-ratoon-wheat sequence on productivity, soil fertility and soil biological properties

Abstract

In a field experiment conducted during 2002 to 2004 in silty clay loam soil at Pantnagar, India, treatment of trash burning þ Sesbania aculeata green manure (GM) incorporation gave the highest increases of 50.6 and 17.7% in ratoon cane yield and 15.0 and 19.4% in wheat grain yield over trash removal and trash burning treatments, respectively. Soil organic C and available N after ratoon and wheat crops were highest with trash removal þ GM incorporation and available P and K with trash removal þ GM mulch. The different treatments of trash and GM management were also superior to trash removal and trash burning in organic C and available N and P in soil at termination of the study. Soil microbial biomass C and dehydrogenase activity at the end were at a maximum with trash burning þ GM mulch and trash removal þ GM mulch treatments, respectively. Compared to trash removal and trash burning, counts of bacteria in soil after ratoon and wheat crops were significantly more only with different GM treatments; however, all GM and trash application treatments recorded significantly higher counts of fungi and actinomycetes. Irrespective of the treatments, population of total bacteria in soil decreased, while that of fungi and actinomycetes increased as compared to their initial counts following sugarcane-ratoon-wheat sequence.

A Review on Effect of INM on Sugarcane Growth, Yield and Quality

“…Srivastava et al, (2008) reported highest cane yield with sulphitation press mud (@ 10 t ha -1 ) + FYM (@ 10 t ha -1 ) in autumn and spring planted sugarcane crop. Trash burning along with incorporation of Sesbania aculeata gave 50.6 and 17.7 per cent increase in ratoon cane yield over trash removal and trash burning treatments respectively (Chandra et al, 2008). Integration of FYM at 25 per cent RDN with fertilizers and biofertilizers to plant crop and trash incorporation (@ 10 t ha -1 ) to ratoon crop increased cane yield (Virdia et al, 2009).…”

Multi-Analytical Interactions in Support of Sugarcane Agroecosystems Sustainability in Tropical Soils

“…Schumann et al [66] published an interesting review of green manuring practices in sugarcane production. However, only recently, the effects of green manure on soil microbial populations, diversity, and activity in sugarcane soils have been reported [67], in which decrease in the total bacterial population in the soil was revealed, while that of fungi and actinomycetes increased. In addition, Ambrosano et al [68] verified that green manure is an alternative source of N for sugarcane crops and can supplement or even replace mineral N fertilization.…”

Efecto de la aplicación de levasa (mosto de caña de azúcar) en la producción y calidad de Agave Tequilana Weber

“…Entre gran variedad de fertilizantes orgánicos que se encuentran disponibles en el mercado, el mosto de caña de azúcar, que se obtiene como un subproducto del proceso industrial en la producción de levaduras para la panificación, ha mostrado buenos resultados en la producción de diversos cultivos; sin embargo, no se encuentran reportados; sólo hay información a nivel de residuos de caña azúcar (Chandra et al, 2008). El objetivo del presente estudio fue evaluar el efecto de dosis crecientes de mosto de caña de azúcar en el desarrollo, rendimiento y calidad de Agave tequilana Weber Var.…”
