The field study was conducted during winter season of 1999–2000. The experiment was conducted in completely randomized block design with fifteen treatments. There were significant differences in Crop growth rate (CGR) with respect to various herbicides between 30–60 days after sowing. Pendimethalin 1.0 kg ha−1 and weed free treatment being at par recorded highest CGR as compared to rest of the treatments. Higher Relative growth rate (RGR) values were found in treatments like pendimethalin 1.0 kg. Oxyfluorfen 0.3 kg; linuron and fluchloraiin each at 1.0 kg ha−1 and fenoxaprop 60 g ha−1 at 30–60 days after sowing. Pendimethalin 1.0 kg ha−1 provided significantly higher Leaf abscission rate (LAR) between 60–90 days. Weed free treatment being on par with linuron 1.0 kg ha−1 recorded higher CGR, RGR and Leaf production rate (LPR) values and proved best treatment for seed production of French bean.
