Abstract
A field study comprising fertilizer application and competition periods was conducted during 1992-94 using a split-plot design. Phosphorus concentrati on and its uptake by Lamb's quarters (Chenopodium album L.) was significant ly more in broadcast incorporate method than side placement. Wheat (Triticu m aestivum L. emend Fiori & Paol.) showed high concentration and uptake of P in side placement. Maximum P concentration and its uptake by Lamb's quart ers was 1.12% and 1.24 kg/ha respectively in 6 weeks competition. Maximum p hosphorus concentration and its uptake for wheat was 0.72% and 25.75 kg/ha at 5 weeks after emergence and in full season competition respectively.
