Abstract

A field experiment was carried out during kharif 2009-10 to 2011-12 at Agronomy Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar, Gujarat to study the effect of herbicides on weed control and yield of groundnut (Arachis hypogaea L.). Nine treatments of weed control were evaluated in randomized block design and replicated four times. Besides weed free treatment, an application of pendimethalin @ 1000 g/ha PE + imazethapyr 75 g/ha PoE at 15-20 DAS and H. W. + IC at 20 and 40 DAS recorded higher mature pods per plant, shelling percent, pod yield,  haulm yield, gross return, net return, BCR and weed control efficiency as well as lower weed index and dry weight of  weeds.  No adverse effect of herbicides was observed on plant population, grain and straw yield of succeeding wheat crop.
