Re-visiting of nitrogen and sulphur requirements in Indian mustard (Brassica juncea) under irrigated conditions

Present study was carried out during 2018–19 and 2019–20 at ICAR-Directorate of Rapeseed-Mustard Research, Bharatpur, Rajasthan to evaluate the effect nitrogen (N) sulphur (S) nutrition on production efficiency, water productivity, economics Indian mustard [Brassica juncea (L.) Czern & Coss.] under irrigated conditions. The experiment conducted in a split plot design with 5 levels (0, 60, 80, 100 120 kg/ha) as main treatment 4 20, 40, 60 subplot 3 replications. Results revealed that application kg N/ha recorded highest plant height (205 cm), leaf area index (5.4), number leaves/ (47.3), primary branches/plant (6.8), secondary (18.9), SCMR (46.5), siliquae/plant (382), seeds/silique (18), stem girth (6.65 test weight (5.79 g) seed yield (3.04 t/ha). Among different S levels, maximum values growth physiological parameters, attributes were S/ha (2.71 Similarly, efficiency (22.1 kg/ha/day) productivity (1.53 seed/m3) found higher than S/ha. net monetary returns Benefit cost (B: C) ratio S/ha.Thus, N may be revised kg/ha, respectively for semi-arid climates achieve profitability.
