A field experiment was conducted at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan), during 1998-99 and 1999-2000. Pooled analysis of data indicated a significant improvement in wheat (Tnticum aestivum L. emend. Fiori & Paol.) growth (plant height and total tillerslm2), yield attributes (effec- tive tillerslm2, grainslear), yields, benefit : cost ratio and P uptake was recorded with the herbicides but all were at par with each other. Pendimethalin resulted in highest grain (47.2 qlha), straw (63.3 qlha) and biological (1 10.5 qlha) yields as well as P uptake (30.4 kglha) followed by isoproturon. However, maximum benefit : cost ratio (3.60) was obtained from isoproturon followed by pendimethalin (3.15). Further, weed- control efficiency of all the herbicides did not produce significant variation with each other. P fertilization at 45 kg P20$ha significantly enhanced the plant height, total tillerslm2, effective tillerslm2, grainslear, test weight and yield as well as benefit : cost ratio (3.19) and P uptake (28.6 kglha) over 30 kg P20,1ha. Seed inoculation with phosphate-solubilizing bac- teria (PSB) had significantly positive effects on total tillerslm2, effective tillerslm2 and grainslear as well as yield, benefit : cost ratio (3.18) and P uptake (29.0 kglha) by crop compared to no inoculation.References
