A field experiment entitled, “Effect of Potassium on Growth, Yield and Quality of Groundnut (Arachis hypogaea L.) grown in loamy sand soil” was carried out at Castor - Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during summer2017. The soil of the experimental field was loamy sand in texture; neutral in reaction (pH- 7.2) and electrical conductivity (EC- 0.1 dSm-1); low in both organic carbon (0.2 %) and available N (156 kg/ha); medium in both available P2O5 (44.2 kg/ha) and available K2O (256 kg/ha).Total ten treatments namely,T1: RDF (25:50:00 kg/ha),T2 : RDF + KSB, T3 : RDF + 20 kg K2O,T4 : RDF + 40 kg K2O, T5: RDF + 15 kg K2O + KSB, T6 : RDF + 30 kg K2O + KSB, T7: 75 % RDF + NPK consortium, T8:NPK consortium, T9 : RDF + NPK consortium and T10 : Absolute control were evaluated in randomised block design with three replications with groundnut variety GG 2 as a test crop.Almost all the growth and yield parameters of groundnut viz., plant height at harvest (58.3 cm), number of pod per plant (29.3), pod yield (2872 kg/ha) and haulm yield (4274kg/ha) were recorded significantly higher with application of RDF + NPK consortium (T9) over the rest of the treatments. With regards to oil content of groundnut application of RDF + NPK consortium (T9) gave significant impact on increment of oil content in kernel (48.35 %). However, the fatty acid profile (%) of groundnut oil was not affected significantly due to different treatments. Higher benefit: cost ratio of 3.70 was observed with treatment RDF + NPK consortium (T9).
