Abstract:

A field experiment was conducted during the winter season of 1997-98 on sandy-loam soil in New Delhi, India, to study the effect of irrigation levels (irrigation at the flowering stage or at the flowering and pod development stages), dates of sowing (16 October, 31 October and 15 November) and cultivars (Synthetic Early Juncea 2 or SEJ 2 and Pusa Bold) on the growth, yield attributes (plant height, number of branches per plant, number of siliquae per plant, number of seeds per siliqua and 1000-seed weight), productivity, consumptive water use and water use efficiency of Indian mustard (B. juncea). Growth, yield attributes, yields (seed and oil yields) and consumptive water use increased, whereas water use efficiency decreased with increasing irrigation level. The average increase in seed yield with irrigation at the flowering and pod development stages and irrigation at the flowering stage over the control was 62.9 and 41.7%, respectively. The crop sown on 16 October recorded a higher seed yield (1945 kg/ha) than the crops sown on 31 October (1556 kg/ha) and 15 November (872 kg/ha). Delayed sowing beyond 16 October significantly reduced growth, yield attributes, yields, consumptive water use and water use efficiency. Pusa Bold was superior to SEJ 2 in terms of growth, yield characters, yields (1527 kg/ha) and consumptive water use (235.5 mm), but a higher water use efficiency (0.70 kg/m3 of water) was recorded for SEJ 2.
