Field experiments were conducted during rabi seasons of 1997-98 and 1998-99 at Varanasi, India, to study the effect of plant population and sulfur levels on root growth, consumptive use, productivity and moisture use efficiency of mustard (Brassica juncea) varieties viz. 'Sanjukta Asceh' and 'Varuna' under rainfed conditions. Variety 'Varuna' proved superior to 'Sanjukta Asceh' in respect of dry weight of root (g plant-1) and seed yield (kg ha-1) during both the years. Interaction effects of variety and plant population were found significant on pooled seed yield. Variety Varuna recorded the maximum seed yield at the intermediate population level of 1 48 000 ha-1. Averaged over seasons, 'Varuna' recorded consumptive use of 150.5 mm, seed yield of 1258 kg ha-1 and moisture use efficiency of 8.4 kg seed ha-1 mm-1 as compared to 127.3 mm, 850 kg ha-1 and 6.7 kg ha-1 mm-1 in 'Sanjukta Asceh', respectively. Moisture use efficiency increased with increase in levels of plant population. The crop responded up to 20 kg S ha-1.
