This study was conducted to determine the effects of pix on the seed yield and some agronomic characters of peanut cultivar Halisbey in 2011 and 2012. The trial was arranged in the Randomized Complete Blocks Design with three replications. The pix applications at different growing stages significantly increased pod yield. The pod yield was 5808 kg ha-1 in the pix applied plot while 4930 kg ha-1 in the control plot. The highest pod yield increases (17.8% and 15.7%) were obtained from pix applied plots at four (beginning of the flowering + peg formation + pod formation + seed formation) and three (beginning of flowering + peg formation + pod formation) different growing stages respectively
