Abstract: A field experiment entitled was conducted at Research Farm, AICRP on Forage Crops, Department of Agronomy and Plant Physiology, JNKVV, Jabalpur (Madhya Pradesh) during Kharif season of the year 2018-19. The treatments comprised of 7 weeds control methods viz. application of herbicides Tembotrione @120g ha^-1, Topramezon @35g ha^-1, Tembotrione+Atrazine @120g+250g ha^-1, Topramezon+Atrazine @35g+250g ha^-1, 2,4-D @500g ha^-1, two hand weeding, and another one kept untreated (weedy check) in each replication. The research experiment was laid out in a randomized block design replicated thrice. Plant height significantly increased due to weed control treatments. The highest plant height was noted in treatment T₆ hand weeding and lowest plant height in treatment T₇- Control (weedy check) The biochemical estimations viz., protein (%), fat (%), carbohydrate (%), fibre (%), ash (%) significantly influenced by weed control treatments. Treatment T₆-Hand weeding had maximum value of carbohydrate (69.33), fat (3.95), fibre (2.87), ash (2.64). Whereas, treatment T₄-Topramizon + Atrazine @35g+250g ha^-1 found maximum value of protein (9.97). The major yield components were also found superior for number of cobs plant^-1, cob length, cob girth, number of grains cob^-1, cob weight, 100 grain weight including high biological yield and seed yield and highest harvest index in the hand weeding treatment (T₆) due to better control of weeds which resulted into better photo assimilate transportation towards the sink.
