Abstract: A field experiment was conducted during four kharif season (2010 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 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 results revealed that the average pod as well as haulm yield of groundnut was significantly influenced by different potassium treatments. The average higher pod (1485 kg ha-1) and haulm (3747 kg ha-1) yield were recorded with application of 50 kg K2O ha-1 in two split. Increase in groundnut pod yield to the tune of 34 percent over control. The shelling percentage and oil content in kernel was significantly affected by different potassium treatments. The maximum shelling percentage and oil content was recorded with potassium application of 50 kg K2O ha-1 as basal and in two split, respectively. Significantly higher N, P, K and S uptake by pod and haulm were recorded with treatment application of 75 kg K2O ha-1 as basal and in two split, respectively.
