Abstract
Reid studies carried out during 1998–99 and 1999–2000 revealed that the LAI of frenchbean increased upto 60 DAS and thereafter, it decreased under all the weed control treatments and different levels of nitrogen. Maximum values of fresh as well as dry weight per plant, LAI, NAR, CGR, RGR, harvest Index and seed yield were recorded under weed free condition, followed by application of pendimethalin @ 0.75 kg/ha+one HW at 45 DAS, Ukewise, physiological parameters viz., fresh as well as dry matter production per plant LAI, NAR, RGR, CGR and harvest index were significantly higher under the highest level of nitrogen Le. 120 kg N/ha. The lowest values of all the growth parameters were registered under the weedy check treatment receiving no nitrogen
