Synopsis

Standardization of fertigation regimes for ginger (Zingiber officinale Rosc.) cultivars was studied at the Department of Horticulture, GKVK, UAS, Bangalore during 2021–22 under the eastern dry zone of Karnataka. Two cultivars, Rio-de-Janeiro and Himachal, were evaluated in RCBD with 11 treatments replicated thrice. Treatments included 50–200% RDF applied through fertigation, alone or with biofertilizers (Azotobacter, PSB, AMF, and potassium mobilizers), along with FYM and neem cake.Results showed that 200% RDF (200:100:100 kg N:P₂O₅:K₂O/ha) via fertigation + FYM (30 t/ha) + neem cake (2 t/ha) significantly improved growth and yield. It recorded maximum plant height (40.24, 41.50 cm), tillers/clump (115.86, 112.40), leaves/plant (10.26, 9.66), primary (3.56, 4.96) and secondary fingers (2.93, 3.80), fresh (11.46, 14.54 t/ha) and dry rhizome yield (3.81, 2.47 t/ha) in Rio-de-Janeiro and Himachal, respectively. Quality parameters such as gingerol (11.75–12.00%), oleoresin (9.26–9.47%), crude fibre (6.10–6.18%), and essential oil (2.94–3.00%) were also highest. Maximum B:C ratio was 1.95 (Rio-de-Janeiro) and 2.58 (Himachal).
