INFLUENCE OF PHOSPHORUS AND POTASSIUM ON RAIN-FED GROUNDNUT (ARACHIS-HYPOGAEA)

The field experiment was conducted during rainy (kharif) seasons of 19 87 -- 89 to find out the effect of phosphorus and potassium on yield a nd yield-attributing characters of rainfed 'Co. l' groundnut (Arachis hypogaea L.). The P and K @ 0, 50, 75, 100 and 150% recommended dose ( 10 and 45 kg/ha each) were compared. Application of recommended dose o f P2O5 and K2O @ 10 and 45 kg/ha respectively along with N @ 10 kg/ha applied basal resulted in increased pod number, 100-kernel weight, per centage of sound mature kernel and shelling as well as pod and haulm y ields.
