Effect of irrigation schedules on productivity, quality and water use of Indian mustard (Brassica juncea) under staggered sowing in Northwest India

A field experiment was conducted during the winter (rabi) seasons of 2019–20 and 2020–21 at Guru Kashi University, Talwandi Sabo, Bathinda (Punjab), to study effect irrigation schedules on different growth, yieldattributing characters, yield, quality water use in Indian mustard [Brassica juncea (L.) Czern.] relation sowing time. Results revealed that, early-sown crop, i.e. 10 October, recorded higher growth parameters, viz. plant height, dry-matter accumulation, primary branches/plants, secondary branches/plant, yield-attributing siliquae/plant, seeds/siliqua, siliqua length 1,000-seed weight mustard. The crop sown October gave highest seed yield (1449 kg/ha) which significantly than 25 (1,171 November (643 kg/ha). Oil nitrogen content protein were also crop. Early-sown resulted 21.2 119.5% water-use efficiency (7.55 kg/ha/mm) (6.23 kg/ha mm) (3.44 Application 3 irrigations, branching, flowering siliqua-formation stages, dry matter, weight, stover harvest index Three irrigations stages (1,658 kg/ha), oil (42.2%), (699.7 kg) (22.3%). This treatment 23.3% (6.50 control (5.27 kg/ha/mm).
