Abstract

Field study was conducted to quantify the relative uptake by wheat and associated weeds under the influence of new herbicides. Minimum NPK uptake by weeds was registered, when weeds were controlled by 2, 4-D (ester) 400 + isoproturon 750 g ha−1, which was followed by sulfosulfuron 25 and 30 g ha−1. Conversely, maximum NPK removal by wheat was registered under the influence of 2, 4-D (ester) 400 + isoproturon 750 g ha−1, the results of which were followed by sulfosulfuron 30 g ha−1in the order of significance.
