ABSTRACT
A field experiment was conducted during summer season of 2009 to study the physiological aspects on weedcontrol efficiency (WCE) in brinjal (Solanum melongena L.) at University of Agricultural Sciences, Dharwad. Theexperiment was laid out in randomized block design with ten treatments consisted of four herbicide treatmentsat two different concentrations with weed free check and unweeded control and replicated at three times. Themorpho-physiological characters and total dry matter accumulation were found to be lowest in unweededcontrol and application of pendimethalin @ 1.5kg e.i. ha-1 increased all these parameters. The growth parametersviz., leaf area, LAI, AGR, CGR, NAR, LAD, SLW and BMD were significantly lower in unweeded control whilethe application of herbicides increased these parameters.
