Abstract
Background: Weeds infestation is one of the major threats to crop production and leads to severe crop-weed competition which finally reduce the crop productivity in term of quality and quantity. To enhance crop productivity therefore efficacy of various pre and post-emergence herbicides were evaluated on the basis of Amaranthus viridis, Commelina benghalensis and Cynodon dactylon population reduction, nutrient concentration and their uptake by groundnut. Methods: The present investigation was conducted consecutively for two kharif seasons of 2016 and 2017, at Instructional Farm, CTAE, MPUAT, Udaipur with six weed management practices and four phosphorus levels thus, 30 treatment combinations; all were evaluated in split-plot design with three replications. Result: The experimental results revealed that all herbicidal treatments as well as weed free recorded significantly lowest weed density as well as highest weed control efficiency, nitrogen, phosphorus and potassium concentration and also their uptake by groundnut as compared to weedy check except quizalofop-ethyl at 30 DAS in respect to control Cynodon dactylon. Further, pod yield response to phosphorus was found quadratic. The results also showed that phosphorus exhibit significantly increase nutrients concentration and their uptake by groundnut over control during the experimentation.
