Abstract: The field experiment was conducted to assess the effect of various levels of potassium on yield of soybean and soil nutrient status on farmer’s field in vertisols at Kanehri, Tq. Barshitakli, Dist. Akola during Kharif 2015-16.The experiment comprised four treatments and six replications as six farmer’s laid out in Randomized Block Design. The treatments comprised of 30:75:00 kg NPK ha^-1 (T₁), 30:75:30 kg NPK ha^-1 (T₂), 30:75:60 kg NPK ha^-1 (T₃) and 30:75:90 kg NPK ha^-1 (T₄). The results of the present experiment indicated that the soil chemical properties viz., pH, EC and organic carbon were significantly improved with the application of 30:75:90 kg NPK ha^-1 followed by 30:75:60 kg NPK ha^-1.The available N, P and K were improved significantly with the application of 90 kg K₂O ha^-1 along with recomended dose of N and P.
