The effects of weed extracts of Ageratum conyzoides L., Chenopodium album L., Cynodon dactylon (L.) Pers. and Parthenium hysterophorus L. were examined on the seed germination, seedling growth, total protein and protein profile in french bean (Phaseolus vulgaris L.) varieties (Pant Anupama, Pant Bean-2, Contender, Arkakomal, HAFB-1 and HAFB-2). The inhibitory effect of weed extracts on seedling growth (length and dry weight) of different varieties followed the order: C. album > A. conyzoides > P. hysterophorus and > C. dactylon. The total protein content was increased with weed extracts in all french bean varieties than control. All weed extracts significantly affected the total number of protein bands present in different varieties as compared to control. The Similarity Index (based on presence and absence of different protein bands between control and treatment) was more similar between C. album × C. dactylon (46.6%) in Pant Bean-2 and less similar between control × P. hysterophorus (18.8%) in Arkakomal.
