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).

Breeding Oilseed Crops for Sustainable Production: Opportunities and Constraints
<i> <p>Breeding Oilseed Crops for Sustainable Production: Opportunities and Constraints</i> presents key insights into accelerating the breeding of sustainable and superior varieties. </p> <p>The book explores the genetic engineering/biotechnology that has played a vital role in transforming economically important traits from distant/wild species to cultivated varieties, enhancing the quality and quantity of oil and seed yield production. Integrated nutrient management, efficient water management, and forecasting models for pests diseases outbreaks and integrated pest and pest management have also added new dimensions in breeding for sustainable production. With the rise in demand, the scientific community has responded positively by directing a greater amount of research towards sustainable production both for edible and industrial uses. </p> <p>Covering the latest information on various major world oil crops including rapeseed mustard, sunflower, groundnut, sesame, oilpalm, cotton, linseed/flax, castor and olive, this book brings the latest advances together in a single volume for researchers and advanced level students. </p>
