ABSTRACT

A field experiment was carried out during kharif seasons of 2003 and 2004. Pooled
analysis of data indicated no significant influence of both phosphorus sources viz.,
DAP and PR (34/74) + cowdung (1:3) + PSB on water relations and quality parameters
of soybean. Phosphorus levels also did not differ significantly. with RWC and proline
content of leav~s, however 60 kg P20 S ha·1 recorded significantly higher oil and protein
content (19.7(j and 40.77 per cent, respectively) and their yields (277.33 and 570.81
kg ha-1, resp~ctively) over 40 kg P205 ha·1• Amongst the agrochemicals, foliar
application of brassinolide (0.25 ppm) significantly reduced proline content and
increased RWC of leaves at 40 and 70 DAS. It also increased oil and protein content
and their yield by 4.44 and 3.42 and 19.32 and 18.24 per cent, respectively over
water spray.
