Impact of Fertigation Regimes on Quality of Ginger (Rio-de-Janeiro and Himachal)

Abstract

Ginger is used as one of the important ingredients in traditional as well as modern medicine besides as a spice. It boosts immunity and is a rich source of many biologically active substances and minerals. Although it is a medicinally important crop, its productivity is, however, affected due to poor nutrient management and therefore it requires an adequate supply of nutrients in the form of inorganic fertilizers or organic manuring, or a mixture of both. In this context, the present study was aimed to investigate the effect of fertigation regimes on quality of ginger (Rio-De-Jenereo and Himachal) at vegetable division in department of Horticulture, Gandhi Krishi Vignana Kendra, University of Agricultural Sciences, Bangalore. The experiment comprised of eleven treatments, Sources of nutrients used were FYM (Farm Yard Manure), Azotobacter, PSB (Phosphate Solubilising Bacteria), AMF (Arbuscular Mycorrhizal Fungi), KMB (Potassium Mobilizing Bio fertilizer), Inorganic sources (Urea, DAP, MOP, SSP, Ginger special, Neem cake). The results showed that the application of 200 % RDF (200:100:100 N: P2O5: K2O kg/ha) fertigation + FYM 30 t/ha, Neem cake 2 t/ha] was found effective for increment in essential oil (%), oleoresin content (%), gingerol (%) and crude fibre (%) in both varieties of ginger among the all treatments evaluated in this zone (Bangalore).
