Abstract: A field experiment was conducted during three summer season (2011 to 2013) at Main Oilseeds Research Station, Junagadh Agricultural University, Junagadh, to study the effect of potassium fertilization on yield, quality and nutrients uptake by summer groundnut. The experiment was laid out in randomized block design with seven treatments comprising of three levels of potassium viz; 25, 50 and 75 kg ha-1 each as basal and in two split (1/2 at sowing and 1/2 at 30 days after sowing) along with control (No potassium). The average higher pod (2505 kg ha-1) and haulm (4479 kg ha-1) yield were recorded with application of 75 kg K2O ha-1 in two split. Increase in groundnut pod yield to the tune of 23.6 percent over control. The higher shelling percentage, oil content and HPS count were recorded with potassium application of 50 kg K2O ha-1 as basal. Significantly higher uptake of N and K by pod and haulm and S by haulm were recorded with application of 75 kg K2O ha-1 in two split while, P uptake by pod and haulm and S uptake by haulm were recorded with application of 50 kg K2O ha-1 in two split.
