Economic Threshold Level of Chenopodium album L. and Phalaris minor Retz. in Wheat

A. Tanveer, S. Ahmad, M. Ayub, A. Ali, R. Ahmad


Two field experiments were conducted to determine the economic threshold level of C. album and P. minor in wheat. Different densities viz., check (weed free). 50. 100. 150. 200. 250. 300. 350. 400. 450 and 500 m-2 of each weed species were maintained separately. Grain yield obtained from plots having C, album densities up to 250 m-2 was not statistically different from that obtained from weed free plots (check). In P. minor, minimum grain yield was obtained at the highest weed density of 500 m-2 as compared with that in the absence of weeds.
