Exploiting Fly Ash as Soil Ameliorant to Improve Productivity of Sabai Grass (Eulaliopsis binata (Retz.) C.E. Hubb) under Acid Lateritic Soil of India

摘要

Present investigation was carried out for two years in sandy loam acid lateritic soil to study the effect of Fly Ash (FA), organic wastes like Farm Yard Manure (FYM), vermicompost (VC) and green manure (Sesbania rostratd) (GM) and chemical fertilizerson growth and yield of sabai grass (Eulaliopsis binata). Integrated application of FA, organic wastes and CF resulted in significantly higher tiller number, dry matter accumulation and green leaf yield as compared to sole application of CF in both the years. Application of fly ash in combination with organic wastes and chemical fertilizers recorded maximum yield advantage (up to 22.8 and 27.6% in the wet season of first and second year, respectively), while the yield increase was 3.6 and 9% in the first and second year, respectively when it was used in combination with only chemical fertilizers. As regards organic wastes GM recorded higher yield as compared to FYM or VC during wet season, however, the performance of sabai grass was superior under residual fertility of VC based treatments as compared to FYM or GM during dry season.
