Effect of weed management on nutrient content, uptake and yield of summer groundnut (Arachis hypogaea L.)

An experiment was conducted to assess the effect of weed management on growth attributes and yield of summer groundnut (Arachis hypogaea L.) during summer, 2015 at the Department of Agronomy, College of Agriculture, JAU, Junagadh. The results of experiment indicated that content and uptake of N, P and K by crop were significantly higher under weed free. Significantly the highest content and uptake of N, P and K by weeds was recorded under weedy check (T1). Significantly higher pod yield, haulm yield and biological yield under weed free.
