Dry Matter of Cymbopogon Martini Stapf and Nutrient Status of the Plant and Soil as Influenced by Fly Ash and Vermicompost
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
Different levels of fly ash and vermicompost in soil were tried and their effect on dry matter (%), plant N, P and K content (%) in Cymbopogon martini Stapf and available soil N, P and K (kg/ha) were observed for a period of two harvests during 2014-2015 at CIMAP, Boduppal, Hyderabad. The perusal of the data revealed that treatment T7 with 6 t/ha of fly ash + 4 t/ha of vermicompost recorded maximum dry matter content (50.95% and 40.76%), plant N (2.14% and 2.03%), P (0.32% and 0.30%) and K (4.23% and 3.79%) content at both harvests. The treatment T1 receiving 10 t/ha of vermicompost recorded maximum soil available N (414.61kg/ha and 372.42 kg/ha) and P (29.32 kg/ha and 21.56 kg/ha) at both harvests. Maximum soil available K (558.25 kg/ha and 542.13 kg/ha) was recorded by the treatment T11 receiving 10 t/ha of fly ash alone. From the investigation, it can be concluded that 6 t/ha of fly ash with 4 t/ha of vermicompost as best treatment as it recorded maximum dry matter and nutrient status in palmarosa, followed by treatments T8, T9, T10 and T11 that were on par with the treatment T7 for dry matter and nutrient status in palmarosa.
