A field experiment was laid out in randomized block design consisting of metsulfuron methyl (a herbicide) treatments at 2, 4, 8 g/ha during two consecutive years. The experiment was designed to study its effect on biochemical attributes viz. total chlorophyll, chlorophyll ‘a’, chlorophyll ‘b’ and total sugar content of wheat crop. Wheat plant samples were collected at 0 (2 h), 15, 30, 45, 60, 75 and 90 days after herbicide application. In general, an increase in the total chlorophyll, chlorophyll ‘a’, chlorophyll ‘b’ and total sugar content was observed after metsulfuron methyl treatment in wheat leaves. The results also revealed that among all the three metsulfuron methyl treatments, highest value of chlorophyll content, sugars content in plant and sugar content in wheat grain was observed in metsulfuron methyl 4 g ha-1 (recommended dose) suggesting weed control efficiency is maximum at recommended dose and indicated the positive correlation between chlorophyll and carbohydrate content at all stages of sampling. Based on the results of our study, it could be concluded that the metsulfuron methyl at recommended dose have a non-significant effect on the biochemical attributes of wheat and can be used by farmers for better yield of crop.
