Effect of FYM, NPK and Algal fertilizers on the Growth and Biomass of Vetiver Grass [Vetiveria zizanioides L.Nass]

Dhirendra Kumar, Kumar Nikhil

Vetiver grass (Vetiveria zizanioides) is a warm season perennial grass grown as a phyto-remediation tool for soil, water, control/check soil erosion on overburden dumps slopes during rainy season and recently proposed as a plant material source for biofuel production. However, limited information exists on Vetiver grass fertility management practices in cropping systems. Therefore, the effects of nitrogen, phosphorus and potassium (NPK) fertilizer in the form of Suphala (15:15:15), Farm yard manure (FYM) and dry algae as algal bio-fertilizer as individual dose and in combination of thereafter. This individual fertilization and combination makes it six different treatments and control with five replications each respectively. Each replication under all the six treatments including control, two numbers of Vetiver grass each were planted in all the 30 pots for this experiment to study the increment in height, culm numbers, root length, root:shoot ratio, fresh and dry above and below ground biomass (FAGB, FBGB, DAGB and DBGB) after 39 and 65days respectively and data analysed.
