Integrated Farming With Organic and Inorganic Fertilizers on Yield and Quality of Ginger (Zingiber Officinales Rosc.)

Ginger is an important rhizomatous spice is widely cultivated in India. A study was conducted to assess the effect of organic manure and inorganic healizer on yield and quality of ginger. Highest rhizome yield (11.59 t/ha) was recorded with azospirillum alone in comparison to inorganic fertilizers although the differences were non significant. The quality attributes significantly increased by all the organic fertilizer treatments. Maximum dry matter (17.7%), oil (2.0%) and oleoresin (6.98%) was recorded under the application of azospirillum + phosphorus + wood ash. The lowest dry matter was recorded with phosphorus alone when no biofertilizer was applied in comparison to inorganic fertilizers.
