Abstract
A field experiment was conducted on sandy-loam soil at the Main Research Station. UAS, Hebbal, Bangalore, during 2 summer seasons of 1990 and 1991, to study the response of soybean [Glycinemnr (L.) Merr.] to organic matter (FYM t ri;e straw in the proportion of 1 :1 at 0,s and 10 tonnesha) and phosphorus (37.5 and 56.25 kg P,o,/ha:~. At the peak growth of 60 DAS, the leaf-area index &AI) was significantly increased from 2.57 in the control to 3.41 and 4.05 with 5 and 10 tonneslha of organic matter. Similarly, grain yield increased significantly from 20.7 to 23.0 and 26.9 qha with increase from 0 to 5 and 10 tonnestha organic matter and 22.7 to 24.1 qha with 37.5 to 56.25 kg P,O,/ha as a result *- - of increwed dry-matter production at various growth stages.References
