Asif Tanveer, Shahbaz Ahmad, Muhammad Ashar Ayub et al. · Journal of Agricultural and Marine Sciences · 1998 · 10.24200/jams.vol3iss2pp7-11

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 …

Competition Effect of Chenopodium album L. for Potassium and Grain Yield in Wheat (Triticum aestivum L.)

Asif Tanveer, Muhammad Ashar Ayub, Riaz Ahmad · Journal of Agricultural and Marine Sciences · 2001 · 10.24200/jams.vol6iss0pp11-14

A field experiment was conducted to estimate potassium (K) and yield losses by Chenopodium album in wheat under different competition periods. The study consisted of zero competition, competition for 3,4,5,6,7,8 weeks after emergence (WAE), and for full season. Potassium concentration in C. album was maximum (4.91 %) w …
