Influence of weed control measures on growth and yield of wheat (Triticum aestivum L.)

One year field experiment was conducted during rabi season of 2021-2022 at the agricultural research farm (Pili Kothi) Tilak Dhari Post Graduate College Jaunpur U.P. The experiment comprised of nine treatments viz. weedy check, weed free (Two hand weeding), Clodinofop @0.005 kg ha^-1, Metsulfuron @0.006 kg ha^-1, Metsulfuron @0.004 kg ha^-1, Pendimethalin @1.25 kg ha^-1,Metribuzin @0.2 kg ha^-1, 2,4-D 0.5 kg ha^-1 and Carfentrazone @0.02 kg ha^-1 replicated four times in Randomized Block Design. Wheat variety HD-2967 was used at attest crop. Application of Metsulfuron @0.006 kg ha^-1 significantly increased the plant height and dry matter accumulation at different growth stages over weedy check resulted into higher yield attributes viz. effective plant population in m2 at 120 days, grain ear^-1 and 1000 grain weight (38.77 g ) consequently, highest grain (45.03 q/ha) Straw (57.19 q/ha) and biological yield (102.22 q/ha) were through controlling weeds by Metsulfuron @0.006 kg ha^-1 after two hand weeding which was at per Metsulfuron @0.004 kg ha^-1 (43.70, 57.69,101.39 q/ha) followed by 2,4-D 0.5 kg ha^-1 and proved significantly superior over rest of other treatments.
